THE COMPANY AND BASIS OF PRESEN

THE COMPANY AND BASIS OF PRESENTATION	12 Months Ended
	Jan. 01, 2017
Organization, Consolidation and Presentation of Financial Statements [Abstract]
THE COMPANY AND BASIS OF PRESENTATION	THE COMPANY AND BASIS OF PRESENTATION QuickLogic Corporation, ("QuickLogic", the "Company"), was founded in 1988 and reincorporated in Delaware in 1999. The Company enables Original Equipment Manufacturers or OEMs to maximize battery life for highly differentiated, immersive user experiences with Smartphone, Wearable, Tablet and Internet-of-Things or IoT devices. QuickLogic delivers these benefits through industry leading ultra-low power customer programmable System on Chip or SoC semiconductor solutions, embedded software, and algorithm solutions for always-on voice and sensor processing, and enhanced visual experiences. The Company is a fabless semiconductor provider of comprehensive, flexible sensor processing solutions, ultra-low power display bridges, and ultra-low power Field Programmable Gate Arrays, or FPGAs. QuickLogic's fiscal year ends on the Sunday closest to December 31. Fiscal years 2016 , 2015 and 2014 ended on January 1, 2017 , January 3, 2016 and December 28, 2014 , respectively. Liquidity The Company has financed its operations and capital investments through sales of common stock, capital and operating leases, and bank lines of credit. As of January 1, 2017 , the Company's principal sources of liquidity consisted of its cash and cash equivalents of $14.9 million and an additional $6.0 million credit line is available for draw at the Company's election upon credit approval under its revolving line of credit arrangement with Silicon Valley Bank. The revolving line of credit will expire in September 2017 and the Company would need to renew this line of credit or find an alternative lender prior to the expiration date. Further, any violations of debt covenants during 2017 will restrict the Company’s access to any additional cash draws from the revolving line of credit, and may require immediate repayment of the outstanding debt amounts. Additionally, the Company has an accumulated deficit of approximately $240 million , has experienced net losses in the past years and expects such losses to continue through at least the end of fiscal year 2017 as the Company continues to develop new products, applications and technologies. On September 25, 2015, the Company entered into a Second Amendment to Third Amended and Restated Loan and Security Agreement with Silicon Valley Bank to extend the line of credit for two years through September 25, 2017 . This amendment modifies some of the financial covenants. This line of credit provides for committed loan advances of up to $6.0 million , subject to increases at the Company's election of up to $12.0 million if the Company meets certain requirements in the debt agreement. On February 10, 2016, the Company entered into a Third Amendment to Third and Restated Loan and Security Agreement to further modify the covenants. See Note 5 for a description of the modified covenants. The Company is in compliance with all loan covenants as of the end of the current reporting period. On March 21, 2016, the Company issued 10.0 million shares of common stock at a price of $1.00 per share, $0.001 par value. The Company received net proceeds of approximately $8.8 million , after deducting underwriting commissions and other offering related expenses. The Company uses the net proceeds from the offering for working capital and other general corporate purposes. The Company may also use a portion of the net proceeds to acquire and/or license technologies and acquire and/or invest in businesses when the opportunity arises. The shares were offered pursuant to a shelf registration statement previously filed with the SEC, which was declared effective by the SEC on August 30, 2013, and as supplemented by a prospectus supplement dated March 17, 2016 filed with the Securities and Exchange Commission or SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended. On December 9, 2016, the Company filed a new shelf registration statement on Form S-3 under which the Company may, from time to time, sell securities in one or more offerings up to a total dollar amount of $40.0 million . The Company's earlier shelf registration statement filed on July 31, 2013 expired on August 30, 2016. The Company currently uses its cash to fund its capital expenditures and operating losses. Based on past performance and current expectations, the Company believes that its existing cash and cash equivalents, together with available financial resources from the revolving line of credit with Silicon Valley Bank will be sufficient to fund its operations and capital expenditures and provide adequate working capital for the next twelve months. The Company’s revolving line of credit with Silicon Valley Bank will expire in September 2017 and the Company would need to renew this line of credit or find an alternative lender prior to the expiration date. Further, any violations of debt covenants during 2017 will restrict the Company’s access to any additional cash draws from the revolving line of credit, and may require immediate repayment of the outstanding debt amounts. Management believes that it is probable that the Company will be able to either renew the revolving line of credit or obtain alternative financing on the acceptable terms. The Company's liquidity is affected by many factors including, among others: the level of revenue and gross profit as a result of the cyclicality of the semiconductor industry; the conversion of design opportunities into revenue; market acceptance of existing and new products including solutions based on its ArcticLink ® and PolarPro ® solution platforms; fluctuations in revenue as a result of product end-of-life; fluctuations in revenue as a result of the stage in the product life cycle of its customers' products; costs of securing access to and availability of adequate manufacturing capacity; levels of inventories; wafer purchase commitments; customer credit terms; the amount and timing of research and development expenditures; the timing of new product introductions; production volumes; product quality; sales and marketing efforts; the value and liquidity of its investment portfolio; changes in operating assets and liabilities; the ability to obtain or renew debt financing and to remain in compliance with the terms of existing credit facilities; the ability to raise funds from the sale of equity in the Company; the issuance and exercise of stock options and participation in the Company's employee stock purchase plan; and other factors related to the uncertainties of the industry and global economics. Over the longer term, the Company anticipates that the generation of sales from its new product offerings, existing cash and cash equivalents, together with financial resources from its revolving line of credit with Silicon Valley Bank, assuming renewal of the line of credit or the Company entering into a new debt agreement with an alternative lender prior to the expiration of the revolving line of credit in September 2017, and its ability to raise additional capital in the public capital markets will be sufficient to satisfy its operations and capital expenditures. However, the Company cannot provide any assurance that it will be able to raise additional capital, if required, or that such capital will be available on terms acceptable to the Company. The inability of the Company to generate sufficient sales from its new product offerings and/or raise additional capital if needed could have a material adverse effect on the Company’s operations and financial condition, including its ability to maintain compliance with its lender’s financial covenants. Principles of Consolidation The consolidated financial statements have been prepared in accordance with Generally Accepted Accounting Principles, in the United States of America or US GAAP and the applicable rules and regulations of the Securities and Exchange Commission, or SEC, and include the accounts of QuickLogic and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. Foreign Currency The functional currency of the Company's non-U.S. operations is the U.S. dollar. Accordingly, all monetary assets and liabilities of these foreign operations are translated into U.S. dollars at current period-end exchange rates and non-monetary assets and related elements of expense are translated using historical exchange rates. Income and expense elements are translated to U.S. dollars using the average exchange rates in effect during the period. Gains and losses from the foreign currency transactions of these subsidiaries are recorded as interest income and other expense, net in the statements of operations. Use of Estimates The preparation of these consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities and the reported amounts of revenue and expenses during the period. Actual results could differ from those estimates, particularly in relation to revenue recognition; the allowance for doubtful accounts; sales returns; valuation of investments; valuation of long-lived assets; valuation of inventories including identification of excess quantities, market value and obsolescence; measurement of stock-based compensation awards; accounting for income taxes and estimating accrued liabilities. Concentration of Risk The Company's accounts receivable are denominated in U.S. dollars and are derived primarily from sales to customers located in North America, Asia Pacific, and Europe. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. See Note 11 for information regarding concentrations associated with accounts receivable. For the twelve months ended January 1, 2017 , the Company generated 33% of its total revenue from shipments to a tier one customer, Samsung Electronics Co., Ltd. ("Samsung"). See Note 11 for information regarding revenue concentrations associated with our customers and distributors.

SIGNIFICANT ACCOUNTING POLICIES

SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended

Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Cash Equivalents The Company considers all short-term, highly liquid investments with an original or a remaining maturity at purchase of ninety days or less to be cash equivalents. The Company's investment portfolio included in cash equivalents is generally comprised of investments that meet high credit quality standards. The Company's investment portfolio consists of money market funds. Fair Value The guidance for the fair value option for financial assets and financial liabilities provides companies the irrevocable option to measure many financial assets and liabilities at fair value with changes in fair value recognized in earnings or equity. The Company has not elected to measure any financial assets or liabilities at fair value that were not previously required to be measured at fair value. Foreign Currency Transactions All of the Company's sales and cost of manufacturing are transacted in U.S. dollars. The Company conducts a portion of its research and development activities in India and has sales and marketing activities in various countries outside of the United States. Most of these international expenses are incurred in local currency. Foreign currency transaction gains and losses, which are not significant, are included in interest income and other expense, net, as they occur. Operating expenses denominated in foreign currencies were approximately 18% , 17% and 18% of total operating expenses in 2016 , 2015 and 2014 respectively. The Company incurred a majority of these foreign currency expenses in India, the United Kingdom and Korea in 2016, 2015 and 2014. The Company has not used derivative financial instruments to hedge its exposure to fluctuations in foreign currency and, therefore, is susceptible to fluctuations in foreign exchange gains or losses in its results of operations in future reporting periods. Inventories Inventories are stated at the lower of standard cost or net realizable value. Standard cost approximates actual cost on a first-in, first-out basis. The Company routinely evaluates quantities and values of its inventories in light of current market conditions and market trends and records reserves for quantities in excess of demand and product obsolescence. The evaluation, which inherently involves judgments as to assumptions about expected future demand and the impact of market conditions on these assumptions, takes into consideration historic usage, expected demand, anticipated sales price, the stage in the product life cycle of its customers' products, new product development schedules, the effect new products might have on the sale of existing products, product obsolescence, customer design activity, customer concentrations, product merchantability and other factors. Market conditions are subject to change. Actual consumption of inventories could differ from forecast demand, and this difference could have a material impact on the Company's gross margin and inventory balances based on additional provisions for excess or obsolete inventories or a benefit from inventories previously written down. The Company also regularly reviews the cost of inventories against estimated market value and records a lower of cost or market reserve for inventories that have a cost in excess of estimated market value, which could have a material impact on the Company's gross margin and inventory balances based on additional write-downs to net realizable value or a benefit from inventories previously written down. The Company's semiconductor products have historically had an unusually long product life cycle and obsolescence has not been a significant factor in the valuation of inventories. However, as the Company pursues opportunities in the mobile market and continues to develop new solutions and products, the Company believes its product life cycle will be shorter which could increase the potential for obsolescence. A significant decrease in demand could result in an increase in excess inventory on hand. Although the Company makes every effort to ensure the accuracy of its forecasts of future product demand, any significant unanticipated changes in demand or frequent new product developments could have a significant impact on the value of its inventory and its results of operations. Property and Equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets, generally one to seven years. Amortization of leasehold improvements and capital leases is computed on a straight-line basis over the shorter of the lease term or the estimated useful lives of the assets, generally one to seven years. Long-Lived Assets The Company reviews the recoverability of its long-lived assets, such as property and equipment, annually and when events or changes in circumstances occur that indicate that the carrying value of the asset or asset group may not be recoverable. The assessment of possible impairment is based on the Company's ability to recover the carrying value of the asset or asset group from the expected future pre-tax cash flows, undiscounted and without interest charges, of the related operations. If these cash flows are less than the carrying value of the asset or asset group, an impairment loss is recognized for the difference between the estimated fair value and the carrying value, and the carrying value of the related assets is reduced by this difference. The measurement of impairment requires management to estimate future cash flows and the fair value of long-lived assets. During 2016 , 2015 and 2014 the Company wrote-off equipment with a net book value of $368,000 , $8,000 and $5,000 , respectively. Licensed Intellectual Property The Company licenses intellectual property that is incorporated into its products. Costs incurred under license agreements prior to the establishment of technological feasibility are included in research and development expense as incurred. Costs incurred for intellectual property once technological feasibility has been established and that can be used in multiple products are capitalized as a long-term asset. Once a product incorporating licensed intellectual property has production sales, the amount is amortized over the estimated useful life of the asset, generally up to five years. Revenue Recognition The Company supplies standard products which must be programmed before they can be used in an application. The Company's products may be programmed by us, distributors, end-customers or third parties. The Company recognizes revenue as products are shipped if evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, collection of the resulting receivable is reasonably assured and product returns are reasonably estimable. Revenue is recognized upon shipment of programmed and unprogrammed parts to both OEM customers and distributors, provided that legal title and risk of ownership have transferred. Parts held by distributors may be returned for quality reasons only under its standard warranty policy. The Company records allowance for sales returns. Amounts recorded for sales returns were $93,000 and $19,000 for the years ended January 1, 2017 and January 3, 2016, respectively Warranty Costs The Company warrants finished goods against defects in material and workmanship under normal use for twelve months from the date of shipment. The Company does not have significant product warranty related costs or liabilities. Advertising Costs related to advertising and promotion expenditures are charged to “Selling, general and administrative” expense in the consolidated statements of operations as incurred. Costs related to advertising and promotion expenditures were $51,000 in 2016, $60,000 in 2015, and were not material in 2014. Stock-Based Compensation The Company accounts for stock-based compensation under the provisions of the amended authoritative guidance, and related interpretations which require the measurement and recognition of expense related to the fair value of stock-based compensation awards. The fair value of stock-based compensation awards is measured at the grant date and re-measured upon modification, as appropriate. The Company uses the Black-Scholes option pricing model to estimate the fair value of employee stock options and rights to purchase shares under the Company's 1999 Employee Stock Purchase Plan, or ESPP, consistent with the provisions of the amended authoritative guidance. The fair value of restricted stock awards, or RSAs, and restricted stock units, or RSUs, is based on the closing price of the Company's common stock on the date of grant. Equity compensation awards which vest with service are expensed on a straight-line basis over the requisite service period. Service based Performance awards are expensed on a straight-line basis over the vesting period. If performance conditions are other than service, an accelerated method of amortization is used, which treats each vesting tranche as a separate award over the expected life of the unit. The Company regularly reviews the assumptions used to compute the fair value of its stock-based awards and it will revise its assumptions as appropriate. In the event that assumptions used to compute the fair value of its stock-based awards are later determined to be inaccurate or if the Company changes its assumptions significantly in future periods, stock-based compensation expense and the results of operations could be materially impacted. See Note 10 for further details. Accounting for Income Taxes The Company is required to estimate its income taxes in each of the jurisdictions in which the Company operates. This process involves estimating the Company's actual current tax exposure together with assessing temporary differences resulting from different tax and accounting treatment of items, such as deferred revenue, allowance for doubtful accounts, the impact of equity awards, depreciation and amortization and employee related accruals. These differences result in deferred tax assets and liabilities, which are included on the Company's balance sheets. The Company must then assess the likelihood that its deferred tax assets will be recovered from future taxable income and to the extent the Company believes that recovery is not likely, it must establish a valuation allowance. Significant management judgment is required in determining the Company's provision for income taxes, the Company's deferred tax assets and liabilities and any valuation allowance recorded against the Company's net deferred tax assets. The Company's deferred tax assets, consisting primarily of net operating loss carryforwards, amounted to $79.2 million tax effected as of the end of 2016 . The Company has also recorded a valuation allowance of $79.2 million , tax effected, as of the end of 2016 due to uncertainties related to the Company's ability to utilize its U.S. deferred tax assets before they expire. In making such determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, ability to project future taxable income, and results of recent operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of its net recorded amount, the Company would make an adjustment to the deferred tax assets valuation allowance, which would reduce its provision for income taxes. The Company accounts for uncertainty in income taxes using a two-step approach for recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Company classifies the liability for unrecognized tax benefits as current to the extent that it anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes. Accrued interest and penalties are included within the related tax liability line in the Consolidated Balance Sheet. Concentration of Credit and Suppliers Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash and cash equivalents and accounts receivable. Cash and cash equivalents are maintained with high quality institutions. The Company's accounts receivable are denominated in U.S. dollars and are derived primarily from sales to customers located in North America, Europe and Asia Pacific. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. See Note 11 for information regarding concentrations associated with accounts receivable. The Company depends on a limited number of contract manufacturers, subcontractors, and suppliers for wafer fabrication, assembly, programming and test of its devices, and for the supply of programming equipment, and these services are typically provided by one supplier for each of the Company's devices. The Company generally purchases these single or limited source services through standard purchase orders. Because the Company relies on independent subcontractors to perform these services, it cannot directly control its product delivery schedules, costs or quality levels. The Company's future success also depends on the financial viability of its independent subcontractors. Comprehensive Income (Loss) Comprehensive income (loss) includes all temporary changes in equity (net assets) during a period from non-owner sources. The Company's comprehensive loss equaled to net loss for all periods presented. New Accounting Pronouncements Recently adopted accounting pronouncements: In August 2014, the Financial Accounting Standards Board or FASB issued Accounting Standards Update or ASU No. 2014-15, Presentation of Financial Statements - Going Concern (Sub Topic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern . This ASU 2014-15 provides guidance to an entity’s management with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are currently commonly provided by entities in the financial statement footnotes. This ASU 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016. The Company adopted this guidance prospectively with no material effect on the consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718) : Improvements to Employee Share-Based Payment Accounting. This update was issued as part of the FASB’s simplification initiative and affects all entities that issue share-based payment awards to their employees. The amendments in this update cover such areas as the recognition of excess tax benefits and deficiencies, the classification of those excess tax benefits on the statement of cash flows, an accounting policy election for forfeitures, the amount an employer can withhold to cover income taxes and still qualify for equity classification and the classification of those taxes paid on the statement of cash flows. The Company has decided to early adopt ASU 2016-09 in Q4 2016 and has elected to continue to estimate their forfeiture rate rather than recognizing forfeitures as they occur. The ASU 2016-09 is considered to be effective from the beginning of the year of adoption. In the year of adoption, ASU 2016-09 requires that the cumulative effect adjustment be recorded to retained earnings. Due to the full valuation allowance, there is no cumulative effect adjustment to record. Excess windfall net operating loss carryforwards are converted into deferred tax net operating losses with a corresponding increase in valuation allowance as of the beginning of 2016; the year of adoption. Recently issued accounting pronouncements not yet adopted: In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. In July 2015, the FASB approved a one-year delay in the effective date by issuing ASU 2015-09, Revenue from Contracts with customers. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The Company is currently evaluating the impact of the adoption of ASU 2014-09 on its consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the measurement of Inventory, which amends the accounting guidance on the valuation of inventory. The guidance requires an entity to measure in scope inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent measurement is unchanged for inventory measured using LIFO or the retail inventory method. The amendments do not apply to inventory that is measured using last-in, first-out (LIFO) or the retail inventory method. The amendments apply to all other inventory, which includes inventory that is measured using first-in, first-out (FIFO) or average cost. This guidance is effective for reporting periods beginning after December 15, 2016, including interim periods within those fiscal years. The Company is currently evaluating the impact of ASU 2015-11 on the consolidated financial statements and footnote disclosures. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases . The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact of our pending adoption of the new standard on the consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-08, Revenue from contracts with customers (Topic 606): Principal versus Agent Considerations Reporting Revenue Gross versus Net. The amendments are intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations by amending certain existing illustrative examples and adding additional illustrative examples to assist in the application of the guidance. The effective date and transition of these amendments is the same as the effective date and transition of ASU 2014-09. Public entities should apply the amendments in ASU 2014-09 for annual reporting periods beginning after December 15, 2017, including interim reporting periods therein (i.e., January 1, 2018, for a calendar year entity). The Company is currently evaluating the impact of our pending adoption of the new standard on the consolidated financial statements. In May 2016, the FASB issued ASU No. 2016-12, Revenue from contracts with customers (Topic 606) : Narrow Scope Improvements and Practical Expedients . This update among other things: (1) clarify the object of the collectability criterion for applying paragraph 606-10-25-7; (2) permit an entity to exclude amounts collected from customers for all sales (and other similar) taxes from transaction price; (3) specify that the measurement date for noncash consideration is contract inception; (4) provide a practical expedient that permits an entity to reflect the aggregate effect of all modifications that occur before the beginning of the earliest period presented when identifying the satisfied and unsatisfied performance obligations, determining the transaction price, and allocating the transaction price to the satisfied and unsatisfied performance obligations; (5) clarify that a completed contract for purposes of transition is a contract for which all (or substantially all) of the revenue was recognized under legacy GAAP before the date of initial application, and (6) clarify that an entity that retrospectively applies the guidance in Topic 606 to each prior period reporting is not required to disclose the effect of the accounting change for the period of adoption. This amendment is effective for public entities for annual reports beginning after December 15, 2017, including interim periods therein. For nonpublic entities one year later. The Company is currently evaluating the impact of our pending adoption of the new standard on the consolidated financial statements. In August 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-15, Statement of Cash Flows (Topic 230) : Classification of Certain Cash Receipts and Cash Payments . This update clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This ASU is effective for public business entities for fiscal years beginning after December 15, 2017, and for interim periods therein with early adoption permitted and must be applied retrospectively to all periods presented. The Company is currently evaluating the impact of our pending adoption of the new standard on the consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity transfers of assets other than inventory. This update removes the requirement under which the income tax consequences of intra-entity transfers are deferred until the assets are ultimately sold to an outside party, except for transfers of inventory. The tax consequences of such transfers would be recognized in tax expense when the transfers occur. The standard is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those annual periods. Early adoption is permitted. The Company is currently evaluating the impact of adopting this guidance on the consolidated financial statements.

Earnings Per Share [Abstract]
NET LOSS PER SHARE	NET LOSS PER SHARE Basic net loss per share is computed by dividing net loss available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net loss per share was computed using the weighted average number of common shares outstanding during the period plus potentially dilutive common shares outstanding during the period under the treasury stock method. In computing diluted net loss per share, the weighted average stock price for the period is used in determining the number of shares assumed to be purchased from the exercise of stock options and warrants. For 2016 , 2015 and 2014 , 7.4 million shares, 7.6 million shares, and 7.0 million shares, respectively, associated with equity awards outstanding and the estimated number of shares to be purchased under the current offering period of the 2009 Employee Stock Purchase Plan were not included in the calculation of diluted net loss per share, as they were considered antidilutive due to the net loss the Company experienced during those years.

FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Pursuant to the accounting guidance for fair value measurements and its subsequent updates, fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market and it considers assumptions that market participants would use when pricing the asset or liability. The accounting guidance for fair value measurement also specifies a hierarchy of valuation techniques based upon whether the inputs to those valuation techniques reflect assumptions other market participants would use based upon market data obtained from independent sources (observable inputs) or reflect the company's own assumption of market participant valuation (unobservable inputs). The fair value hierarchy consists of the following three levels: • Level 1 – Inputs are quoted prices in active markets for identical assets or liabilities. • Level 2 – Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data. • Level 3 – Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable. Money market funds classified within Level 2 because they are not actively traded, have been valued using quoted market prices or alternative pricing sources and models utilizing observable market inputs. The following table presents the Company's financial assets that are measured at fair value on a recurring basis as of January 1, 2017 and January 3, 2016 consistent with the fair value hierarchy provisions of the authoritative guidance (in thousands): As of January 1, 2017 As of January 3, 2016 Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Assets: Money market funds (1) $ 14,692 $ 1,338 $ 13,354 $ — $ 18,021 $ 2,137 $ 15,884 $ — Total assets $ 14,692 $ 1,338 $ 13,354 $ — $ 18,021 $ 2,137 $ 15,884 $ — ___________________________ (1) Money market funds are presented as a part of cash and cash equivalents on the accompanying consolidated balance sheets as of January 1, 2017 and January 3, 2016 .

Accordingly, the Company has provided a full valuation allowance against its U.S. federal and state deferred tax assets at January 1, 2017 . Any future release of the valuation allowance may be recorded as a tax benefit increasing net income or as an adjustment to paid-in capital, based on tax ordering requirements. The Company believes it is more likely than not it will be able to realize its foreign deferred tax assets. Deferred tax balances are comprised of the following (in thousands): January 1, 2017 January 3, 2016 Deferred tax assets: Net operating losses $ 53,924 $ 45,148 Capital losses 2,938 2,938 Accruals and reserves 1,875 1,732 Credits carryforward 5,080 5,831 Depreciation and amortization 14,415 12,738 Stock-based compensation 968 1,012 79,200 69,399 Valuation allowances (79,150 ) (69,349 ) Deferred tax asset $ 50 $ 50 Deferred tax liability — — A rate reconciliation between income tax provisions at the U.S. federal statutory rate and the effective rate reflected in the consolidated statements of operations is as follows: Fiscal Years 2016 2015 2014 Income tax (benefit) at statutory rate $ (6,489 ) $ (5,962 ) $ (4,423 ) State taxes (3 ) 2 — Stock compensation and other permanent differences 211 286 6 Foreign taxes (19 ) 41 22 Benefit allocated from other comprehensive income (loss) — — — Future benefit of deferred tax assets not recognized 6,365 5,779 4,463 Provision for income taxes $ 65 $ 146 $ 68 As of January 1, 2017 , the Company had net operating loss carryforwards of approximately $148.7 million for federal and $57.4 million for state income tax purposes. If not utilized, these carryforwards will expire beginning in 2017 for federal and state purposes. The Company has decided to early adopt ASU 2016-09 in Q4 2016 and has elected to continue to estimate their forfeiture rate rather than recognizing forfeitures as they occur. The ASU 2016-09 is considered to be effective from the beginning of the year of adoption. In the year of adoption, ASU 2016-09 requires that the cumulative effect adjustment be recorded to retained earnings. Due to the full valuation allowance, there is no cumulative effect adjustment to record. Excess windfall net operating loss carryforwards are converted into deferred tax net operating losses with a corresponding increase in valuation allowance as of the beginning of 2016; the year of adoption. The Company has research credit carryforwards of approximately $4.0 million for federal and $4.1 million for state income tax purposes as of January 1, 2017. If not utilized, the federal carryforwards will expire in various amounts beginning in 2018. The California credit can be carried forward indefinitely. Under the Tax Reform Act of 1986, the amount of and the benefit from net operating loss carryforwards and credit carryforwards may be impaired or limited in certain circumstances. Events which may restrict utilization of a company's net operating loss and credit carryforwards include, but are not limited to, certain ownership change limitations as defined in Internal Revenue Code Section 382 and similar state provisions. In the event the Company has had a change of ownership, utilization of carryforwards could be restricted to an annual limitation. The annual limitation may result in the expiration of net operating loss carryforwards and credit carryforwards before utilization. The Company has not undertaken a study to determine if its net operating losses are limited. In the event the Company previously experienced an ownership change, or should experience an ownership change in the future, the amount of net operating losses and research and development credit carryovers available in any taxable year could be limited and may expire unutilized. U.S. income taxes and foreign withholding taxes associated with the repatriation of earnings of foreign subsidiaries were not provided for on a cumulative total of $500,000 of undistributed earnings for certain foreign subsidiaries as of the end of fiscal 2016 . The Company intends to reinvest these earnings indefinitely in the Company's foreign subsidiaries. The Company believes that future domestic cash generation will be sufficient to meet future domestic cash needs. The Company has not recorded a deferred tax liability on the undistributed earnings of non-U.S. subsidiaries. If these earnings were distributed to the United States in the form of dividends or otherwise, or if the shares of the relevant foreign subsidiaries were sold or otherwise transferred, the Company would be subject to additional U.S. income taxes (subject to an adjustment for foreign tax credits) and foreign withholding taxes. The additional net taxes due would be immaterial or would not have a material impact on the Company’s financial position and results of operation. If the Company decides to repatriate foreign earnings, the Company would need to adjust its income tax provision in the period in which it is determined that the earnings will no longer be indefinitely reinvested outside the United States. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands): January 1, 2017 January 3, 2016 December 28, 2014 Beginning balance of unrecognized tax benefits $ 696 $ 516 $ 79 Additions for tax positions related to the prior year 1,204 (3 ) 330 Additions for tax positions related to the current year 150 199 162 Lapse of statues of limitations (36 ) (16 ) (55 ) Ending balance of unrecognized tax benefits $ 2,014 $ 696 $ 516 Out of $2.0 million of unrecognized tax benefits, there were no unrecognized tax benefits that would result in a change in the Company's effective tax rate if recognized in future years. For the twelve month period ended January 1, 2017, the Company does not have any interest accrued related to uncertain tax positions. As of January 1, 2017 and January 3, 2016 the Company had approximately $0 and $17,000 , respectively, of accrued interest and penalties related to uncertain tax positions. The Company is not currently under exam and the Company's historical net operating loss and credit carryforwards may be adjusted by the Internal Revenue Service, or IRS, and other tax authorities until the statute closes on the year in which such attributes are utilized. The Company estimates that its unrecognized tax benefits will not change significantly within the next twelve months. The Company is subject to U.S. federal income tax as well as income taxes in many U.S. states and foreign jurisdictions in which the Company operates. As of January 1, 2017 , fiscal years 2012 onward remain open to examination by the U.S. taxing authorities. The U.S. tax years from 1990 forward remain effectively open to examination due to the carryover of unused net operating losses and tax credits.

RSUs typically vest at a rate of 25% one year after the vesting commencement date, and one eighth every six months thereafter. The Company may implement different vesting schedules in the future with respect to any new equity awards. Employee Stock Purchase Plan The 2009 Employee Stock Purchase Plan, or 2009 ESPP, was adopted in March 2009. In January 2015, the 2009 ESPP was amended by the Board of Directors and approved by the Company's stockholders on April 23, 2015 to reserve an additional 1.0 million shares of common stock for issuance under the 2009 ESPP. As of January 1, 2017 , approximately 3.3 million shares were reserved for issuance under the 2009 ESPP. The 2009 ESPP provides for six month offering periods. Participants purchase shares through payroll deductions of up to 20% of an employee's total compensation (maximum of 20,000 shares per offering period). The 2009 ESPP permits the Board of Directors to determine, prior to each offering period, whether participants purchase shares at: (i) 85% of the fair market value of the common stock at the end of the offering period; or (ii) 85% of the lower of the fair market value of the common stock at the beginning or the end of an offering period. The Board of Directors has determined that, until further notice, future offering periods will be made at 85% of the lower of the fair market value of the common stock at the beginning or the end of an offering period.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION The Company's equity incentive program is a broad-based, long-term retention program intended to attract, motivate, and retain talented employees as well as align stockholder and employee interests. The Company provides stock-based incentive compensation, or awards, to eligible employees and non-employee directors. Awards that may be granted under the program include non-qualified and incentive stock options, restricted stock units, or RSUs, performance-based restricted stock units, or PRSUs, and stock bonus units. To date, awards granted under the program consist of stock options, RSUs and PRSUs. The majority of stock-based awards granted under the program vest over four years. Stock options granted under the program have a maximum contractual term of ten years. Stock-based compensation expense is recognized in the Company's consolidated statements of operations and includes compensation expense for the stock-based compensation awards granted or modified subsequent to January 1, 2006, based on the grant date fair value estimated in accordance with the provisions of the amended authoritative guidance. The impact on the Company's results of operations of recording stock-based compensation expense for fiscal years 2016 , 2015 , and 2014 was as follows (in thousands): Fiscal Years 2016 2015 2014 Cost of revenue $ 132 $ 109 $ 137 Research and development 658 826 924 Selling, general and administrative 794 1,064 1,181 Restructuring costs (1) — 29 — Total costs and expenses $ 1,584 $ 2,028 $ 2,242 (1) Stock-based compensation related to restructuring plan initiated in the second quarter of fiscal year 2015. No stock-based compensation was capitalized during any period presented above. In 2016 , the Company granted restricted stock units, or RSUs, to employees with various vesting terms. Total stock-based compensation related to RSUs was $953,000 in 2016 . The Company issued net shares for the vested RSUs, withholding shares in settlement of employee tax withholding obligations. In 2016 , the Company granted PRSUs to certain officers and cancelled PRSUs granted to certain employees in the prior year. Net credit received to stock-based compensation in 2016 due to the cancellation of PRSUs was $113,000 . The amount of stock-based compensation included in inventories at the end of 2016 , 2015 and 2014 was not significant. Valuation Assumptions The Company uses the Black-Scholes option pricing model to estimate the fair value of employee stock options and rights to purchase shares under the Company's 2009 ESPP. Using the Black-Scholes pricing model requires the Company to develop highly subjective assumptions including the expected term of awards, expected volatility of its stock, expected risk-free interest rate and expected dividend rate over the term of the award. The Company's expected term of awards assumption is based primarily on its historical experience with similar grants. The Company's expected stock price volatility assumption for both stock options and ESPP shares is based on the historical volatility of the Company's stock, using the daily average of the opening and closing prices and measured using historical data appropriate for the expected term. The risk-free interest rate assumption approximates the risk-free interest rate of a Treasury Constant Maturity bond with a maturity approximately equal to the expected term of the stock option or ESPP shares. This fair value is expensed over the requisite service period of the award. The fair value of RSUs and PRSUs is based on the closing price of the Company's common stock on the date of grant. Equity compensation awards which vest with service are expensed using the straight-line attribution method over the requisite service period. In addition to the assumptions used in the Black-Scholes pricing model, the amended authoritative guidance requires that the Company recognize expense for awards ultimately expected to vest; therefore the Company is required to develop an estimate of the number of awards expected to be forfeited prior to vesting, or forfeiture rate. The forfeiture rate is estimated based on historical pre-vest cancellation experience and is applied to all share-based awards. The following weighted average assumptions are included in the estimated fair value calculations for stock option grants: Fiscal Years 2016 2015 2014 Expected term (years) 7.1 6.3 6.6 Risk-free interest rate 1.40 % 1.75 % 1.98 % Expected volatility 52 % 56 % 58 % Expected dividend — — — The methodologies for determining the above values were as follows: • Expected term: The expected term represents the period that the Company's stock-based awards are expected to be outstanding and is estimated based on historical experience. • Risk-free interest rate: The risk-free interest rate assumption is based upon the risk-free rate of a Treasury Constant Maturity bond with a maturity appropriate for the expected term of the Company's employee stock options. • Expected volatility: The Company determines expected volatility based on historical volatility of the Company's common stock according to the expected term of the options. • Expected dividend: The expected dividend assumption is based on the Company's intent not to issue a dividend under its dividend policy. The weighted average estimated fair value for options granted during 2016 , 2015 and 2014 was $0.46 , $0.87 , and $1.99 per option, respectively. As of the end of 2016 , the fair value of unvested stock options, net of expected forfeitures, was approximately $1.6 million . This unrecognized stock-based compensation expense is expected to be recorded over a weighted average period of 3.10 years.

The total intrinsic value of options exercised during 2016 , 2015 and 2014 was $0 , $83,000 and $3.7 million , respectively. Total cash received from employees as a result of employee stock option exercises during 2016 , 2015 and 2014 was approximately $0 , $117,000 and $4.5 million , respectively. The Company settles employee stock option exercises with newly issued common shares. In connection with these exercises, there was no tax benefit realized by the Company due to the Company's current loss position. Total stock-based compensation related to stock options was $486,000 , $861,000 , and $1.1 million for 2016 , 2015 , and 2014 , respectively. Significant exercise price ranges of options outstanding, related weighted average exercise prices and contractual life information at the end of 2016 were as follows: Options Outstanding Options Exercisable Range of Exercise Prices Options Outstanding Weighted Average Remaining Contractual Life Weighted Average Exercise Price Options Vested and Exercisable Weighted Average Exercise Price (in thousands) (in years) (in thousands) $0.78 - $0.78 4 2.17 $ 0.78 5 $ 0.78 0.86 - 0.86 726 9.68 0.86 — — 0.90 - 1.32 463 2.62 0.96 414 0.92 1.63 - 1.63 731 1.92 1.63 731 1.63 2.17 - 2.76 446 4.04 2.29 446 2.29 2.78 - 2.78 1,299 3.08 2.78 1,299 2.78 2.82 - 3.39 635 5.20 3.29 530 3.28 3.48 - 3.82 185 5.63 3.60 164 3.57 3.92 - 3.92 2 4.28 3.92 1 3.92 4.17 - 4.17 488 0.79 4.17 488 4.17 $0.78 - $4.17 4,979 4.06 $ 2.35 4,078 $ 2.59 Restricted Stock Units RSUs entitle the holder to receive, at no cost, one common share for each restricted stock unit on the vesting date as it vests. The Company withholds shares in settlement of employee tax withholding obligations upon the vesting of restricted stock units. The stock-based compensation related to grants of vested RSUs was $953,000 , $834,000 , $854,000 in 2016 , 2015 and 2014 , respectively. In 2016 , the Company cancelled PSU's issued to certain officers, which resulted in a credit of $113,000 to the stock-based compensation.

Sales under the ESPP were 732,000 shares of common stock at an average price of $0.81 for 2016 , 458,000 shares of common stock at an average price of $1.26 for 2015 , and 278,000 shares of common stock at an average price of $2.76 for 2014 . Under the 2009 ESPP, the Company issued 732,000 shares at an average price of $0.81 per share during 2016 . As of January 1, 2017 , 687,000 shares under the 2009 ESPP remained available for issuance. For 2016 , the Company recorded compensation expenses related to the ESPP of $258,000 , $232,000 and $255,000 in 2016, 2015 and 2014, respectively. The fair value of rights issued pursuant to the Company's ESPP was estimated on the commencement date of each offering period using the following weighted average assumptions: Fiscal Years 2016 2015 2014 Expected life (months) 6.1 6.0 6.0 Risk-free interest rate 0.97 % 0.21 % 0.07 % Volatility 59.3 % 55 % 49 % Dividend yield — — — The methodologies for determining the above values were as follows: • Expected term: The expected term represents the length of the purchase period contained in the ESPP. • Risk-free interest rate: The risk-free interest rate assumption is based upon the risk-free rate of a Treasury Constant Maturity bond with a maturity appropriate for the term of the purchase period. • Volatility: The Company determines expected volatility based on historical volatility of the Company's common stock for the term of the purchase period. • Dividend Yield: The expected dividend assumption is based on the Company's intent not to issue a dividend under its dividend policy. As of the end of 2016 , the unrecognized stock-based compensation expense relating to the Company's ESPP was $97,000 and was expected to be recognized over a weighted average period of approximately 4.5 months.

Liquidity	Liquidity The Company has financed its operations and capital investments through sales of common stock, capital and operating leases, and bank lines of credit. As of January 1, 2017 , the Company's principal sources of liquidity consisted of its cash and cash equivalents of $14.9 million and an additional $6.0 million credit line is available for draw at the Company's election upon credit approval under its revolving line of credit arrangement with Silicon Valley Bank. The revolving line of credit will expire in September 2017 and the Company would need to renew this line of credit or find an alternative lender prior to the expiration date. Further, any violations of debt covenants during 2017 will restrict the Company’s access to any additional cash draws from the revolving line of credit, and may require immediate repayment of the outstanding debt amounts. Additionally, the Company has an accumulated deficit of approximately $240 million , has experienced net losses in the past years and expects such losses to continue through at least the end of fiscal year 2017 as the Company continues to develop new products, applications and technologies. On September 25, 2015, the Company entered into a Second Amendment to Third Amended and Restated Loan and Security Agreement with Silicon Valley Bank to extend the line of credit for two years through September 25, 2017 . This amendment modifies some of the financial covenants. This line of credit provides for committed loan advances of up to $6.0 million , subject to increases at the Company's election of up to $12.0 million if the Company meets certain requirements in the debt agreement. On February 10, 2016, the Company entered into a Third Amendment to Third and Restated Loan and Security Agreement to further modify the covenants. See Note 5 for a description of the modified covenants. The Company is in compliance with all loan covenants as of the end of the current reporting period. On March 21, 2016, the Company issued 10.0 million shares of common stock at a price of $1.00 per share, $0.001 par value. The Company received net proceeds of approximately $8.8 million , after deducting underwriting commissions and other offering related expenses. The Company uses the net proceeds from the offering for working capital and other general corporate purposes. The Company may also use a portion of the net proceeds to acquire and/or license technologies and acquire and/or invest in businesses when the opportunity arises. The shares were offered pursuant to a shelf registration statement previously filed with the SEC, which was declared effective by the SEC on August 30, 2013, and as supplemented by a prospectus supplement dated March 17, 2016 filed with the Securities and Exchange Commission or SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended. On December 9, 2016, the Company filed a new shelf registration statement on Form S-3 under which the Company may, from time to time, sell securities in one or more offerings up to a total dollar amount of $40.0 million . The Company's earlier shelf registration statement filed on July 31, 2013 expired on August 30, 2016. The Company currently uses its cash to fund its capital expenditures and operating losses. Based on past performance and current expectations, the Company believes that its existing cash and cash equivalents, together with available financial resources from the revolving line of credit with Silicon Valley Bank will be sufficient to fund its operations and capital expenditures and provide adequate working capital for the next twelve months. The Company’s revolving line of credit with Silicon Valley Bank will expire in September 2017 and the Company would need to renew this line of credit or find an alternative lender prior to the expiration date. Further, any violations of debt covenants during 2017 will restrict the Company’s access to any additional cash draws from the revolving line of credit, and may require immediate repayment of the outstanding debt amounts. Management believes that it is probable that the Company will be able to either renew the revolving line of credit or obtain alternative financing on the acceptable terms. The Company's liquidity is affected by many factors including, among others: the level of revenue and gross profit as a result of the cyclicality of the semiconductor industry; the conversion of design opportunities into revenue; market acceptance of existing and new products including solutions based on its ArcticLink ® and PolarPro ® solution platforms; fluctuations in revenue as a result of product end-of-life; fluctuations in revenue as a result of the stage in the product life cycle of its customers' products; costs of securing access to and availability of adequate manufacturing capacity; levels of inventories; wafer purchase commitments; customer credit terms; the amount and timing of research and development expenditures; the timing of new product introductions; production volumes; product quality; sales and marketing efforts; the value and liquidity of its investment portfolio; changes in operating assets and liabilities; the ability to obtain or renew debt financing and to remain in compliance with the terms of existing credit facilities; the ability to raise funds from the sale of equity in the Company; the issuance and exercise of stock options and participation in the Company's employee stock purchase plan; and other factors related to the uncertainties of the industry and global economics. Over the longer term, the Company anticipates that the generation of sales from its new product offerings, existing cash and cash equivalents, together with financial resources from its revolving line of credit with Silicon Valley Bank, assuming renewal of the line of credit or the Company entering into a new debt agreement with an alternative lender prior to the expiration of the revolving line of credit in September 2017, and its ability to raise additional capital in the public capital markets will be sufficient to satisfy its operations and capital expenditures. However, the Company cannot provide any assurance that it will be able to raise additional capital, if required, or that such capital will be available on terms acceptable to the Company. The inability of the Company to generate sufficient sales from its new product offerings and/or raise additional capital if needed could have a material adverse effect on the Company’s operations and financial condition, including its ability to maintain compliance with its lender’s financial covenants.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements have been prepared in accordance with Generally Accepted Accounting Principles, in the United States of America or US GAAP and the applicable rules and regulations of the Securities and Exchange Commission, or SEC, and include the accounts of QuickLogic and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated.
Foreign Currency Transactions	Foreign Currency The functional currency of the Company's non-U.S. operations is the U.S. dollar. Accordingly, all monetary assets and liabilities of these foreign operations are translated into U.S. dollars at current period-end exchange rates and non-monetary assets and related elements of expense are translated using historical exchange rates. Income and expense elements are translated to U.S. dollars using the average exchange rates in effect during the period. Gains and losses from the foreign currency transactions of these subsidiaries are recorded as interest income and other expense, net in the statements of operations. Foreign Currency Transactions All of the Company's sales and cost of manufacturing are transacted in U.S. dollars. The Company conducts a portion of its research and development activities in India and has sales and marketing activities in various countries outside of the United States. Most of these international expenses are incurred in local currency. Foreign currency transaction gains and losses, which are not significant, are included in interest income and other expense, net, as they occur. Operating expenses denominated in foreign currencies were approximately 18% , 17% and 18% of total operating expenses in 2016 , 2015 and 2014 respectively. The Company incurred a majority of these foreign currency expenses in India, the United Kingdom and Korea in 2016, 2015 and 2014. The Company has not used derivative financial instruments to hedge its exposure to fluctuations in foreign currency and, therefore, is susceptible to fluctuations in foreign exchange gains or losses in its results of operations in future reporting periods.
Use of Estimates	Use of Estimates The preparation of these consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities and the reported amounts of revenue and expenses during the period. Actual results could differ from those estimates, particularly in relation to revenue recognition; the allowance for doubtful accounts; sales returns; valuation of investments; valuation of long-lived assets; valuation of inventories including identification of excess quantities, market value and obsolescence; measurement of stock-based compensation awards; accounting for income taxes and estimating accrued liabilities.
Concentration of Credit and Suppliers	Concentration of Risk The Company's accounts receivable are denominated in U.S. dollars and are derived primarily from sales to customers located in North America, Asia Pacific, and Europe. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. See Note 11 for information regarding concentrations associated with accounts receivable. Concentration of Credit and Suppliers Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash and cash equivalents and accounts receivable. Cash and cash equivalents are maintained with high quality institutions. The Company's accounts receivable are denominated in U.S. dollars and are derived primarily from sales to customers located in North America, Europe and Asia Pacific. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. See Note 11 for information regarding concentrations associated with accounts receivable. The Company depends on a limited number of contract manufacturers, subcontractors, and suppliers for wafer fabrication, assembly, programming and test of its devices, and for the supply of programming equipment, and these services are typically provided by one supplier for each of the Company's devices. The Company generally purchases these single or limited source services through standard purchase orders. Because the Company relies on independent subcontractors to perform these services, it cannot directly control its product delivery schedules, costs or quality levels. The Company's future success also depends on the financial viability of its independent subcontractors.
Cash Equivalents	Cash Equivalents The Company considers all short-term, highly liquid investments with an original or a remaining maturity at purchase of ninety days or less to be cash equivalents. The Company's investment portfolio included in cash equivalents is generally comprised of investments that meet high credit quality standards. The Company's investment portfolio consists of money market funds.
Fair Value	Fair Value The guidance for the fair value option for financial assets and financial liabilities provides companies the irrevocable option to measure many financial assets and liabilities at fair value with changes in fair value recognized in earnings or equity. The Company has not elected to measure any financial assets or liabilities at fair value that were not previously required to be measured at fair value.
Inventories	Inventories Inventories are stated at the lower of standard cost or net realizable value. Standard cost approximates actual cost on a first-in, first-out basis. The Company routinely evaluates quantities and values of its inventories in light of current market conditions and market trends and records reserves for quantities in excess of demand and product obsolescence. The evaluation, which inherently involves judgments as to assumptions about expected future demand and the impact of market conditions on these assumptions, takes into consideration historic usage, expected demand, anticipated sales price, the stage in the product life cycle of its customers' products, new product development schedules, the effect new products might have on the sale of existing products, product obsolescence, customer design activity, customer concentrations, product merchantability and other factors. Market conditions are subject to change. Actual consumption of inventories could differ from forecast demand, and this difference could have a material impact on the Company's gross margin and inventory balances based on additional provisions for excess or obsolete inventories or a benefit from inventories previously written down. The Company also regularly reviews the cost of inventories against estimated market value and records a lower of cost or market reserve for inventories that have a cost in excess of estimated market value, which could have a material impact on the Company's gross margin and inventory balances based on additional write-downs to net realizable value or a benefit from inventories previously written down. The Company's semiconductor products have historically had an unusually long product life cycle and obsolescence has not been a significant factor in the valuation of inventories. However, as the Company pursues opportunities in the mobile market and continues to develop new solutions and products, the Company believes its product life cycle will be shorter which could increase the potential for obsolescence. A significant decrease in demand could result in an increase in excess inventory on hand. Although the Company makes every effort to ensure the accuracy of its forecasts of future product demand, any significant unanticipated changes in demand or frequent new product developments could have a significant impact on the value of its inventory and its results of operations.
Property and Equipment and Long-Lived Assets	Property and Equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets, generally one to seven years. Amortization of leasehold improvements and capital leases is computed on a straight-line basis over the shorter of the lease term or the estimated useful lives of the assets, generally one to seven years. Long-Lived Assets The Company reviews the recoverability of its long-lived assets, such as property and equipment, annually and when events or changes in circumstances occur that indicate that the carrying value of the asset or asset group may not be recoverable. The assessment of possible impairment is based on the Company's ability to recover the carrying value of the asset or asset group from the expected future pre-tax cash flows, undiscounted and without interest charges, of the related operations. If these cash flows are less than the carrying value of the asset or asset group, an impairment loss is recognized for the difference between the estimated fair value and the carrying value, and the carrying value of the related assets is reduced by this difference. The measurement of impairment requires management to estimate future cash flows and the fair value of long-lived assets.
Licensed Intellectual Property	Licensed Intellectual Property The Company licenses intellectual property that is incorporated into its products. Costs incurred under license agreements prior to the establishment of technological feasibility are included in research and development expense as incurred. Costs incurred for intellectual property once technological feasibility has been established and that can be used in multiple products are capitalized as a long-term asset. Once a product incorporating licensed intellectual property has production sales, the amount is amortized over the estimated useful life of the asset, generally up to five years.
Revenue Recognition	Revenue Recognition The Company supplies standard products which must be programmed before they can be used in an application. The Company's products may be programmed by us, distributors, end-customers or third parties. The Company recognizes revenue as products are shipped if evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, collection of the resulting receivable is reasonably assured and product returns are reasonably estimable. Revenue is recognized upon shipment of programmed and unprogrammed parts to both OEM customers and distributors, provided that legal title and risk of ownership have transferred. Parts held by distributors may be returned for quality reasons only under its standard warranty policy. The Company records allowance for sales returns. Amounts recorded for sales returns were $93,000 and $19,000 for the years ended January 1, 2017 and January 3, 2016, respectively
Warranty Costs	Warranty Costs The Company warrants finished goods against defects in material and workmanship under normal use for twelve months from the date of shipment. The Company does not have significant product warranty related costs or liabilities.
Advertising	Advertising Costs related to advertising and promotion expenditures are charged to “Selling, general and administrative” expense in the consolidated statements of operations as incurred.
Stock-Based Compensation and Valuation Assumptions	Stock-Based Compensation The Company accounts for stock-based compensation under the provisions of the amended authoritative guidance, and related interpretations which require the measurement and recognition of expense related to the fair value of stock-based compensation awards. The fair value of stock-based compensation awards is measured at the grant date and re-measured upon modification, as appropriate. The Company uses the Black-Scholes option pricing model to estimate the fair value of employee stock options and rights to purchase shares under the Company's 1999 Employee Stock Purchase Plan, or ESPP, consistent with the provisions of the amended authoritative guidance. The fair value of restricted stock awards, or RSAs, and restricted stock units, or RSUs, is based on the closing price of the Company's common stock on the date of grant. Equity compensation awards which vest with service are expensed on a straight-line basis over the requisite service period. Service based Performance awards are expensed on a straight-line basis over the vesting period. If performance conditions are other than service, an accelerated method of amortization is used, which treats each vesting tranche as a separate award over the expected life of the unit. The Company regularly reviews the assumptions used to compute the fair value of its stock-based awards and it will revise its assumptions as appropriate. In the event that assumptions used to compute the fair value of its stock-based awards are later determined to be inaccurate or if the Company changes its assumptions significantly in future periods, stock-based compensation expense and the results of operations could be materially impacted. See Note 10 for further details. Valuation Assumptions The Company uses the Black-Scholes option pricing model to estimate the fair value of employee stock options and rights to purchase shares under the Company's 2009 ESPP. Using the Black-Scholes pricing model requires the Company to develop highly subjective assumptions including the expected term of awards, expected volatility of its stock, expected risk-free interest rate and expected dividend rate over the term of the award. The Company's expected term of awards assumption is based primarily on its historical experience with similar grants. The Company's expected stock price volatility assumption for both stock options and ESPP shares is based on the historical volatility of the Company's stock, using the daily average of the opening and closing prices and measured using historical data appropriate for the expected term. The risk-free interest rate assumption approximates the risk-free interest rate of a Treasury Constant Maturity bond with a maturity approximately equal to the expected term of the stock option or ESPP shares. This fair value is expensed over the requisite service period of the award. The fair value of RSUs and PRSUs is based on the closing price of the Company's common stock on the date of grant. Equity compensation awards which vest with service are expensed using the straight-line attribution method over the requisite service period.
Accounting for Income Taxes	Accounting for Income Taxes The Company is required to estimate its income taxes in each of the jurisdictions in which the Company operates. This process involves estimating the Company's actual current tax exposure together with assessing temporary differences resulting from different tax and accounting treatment of items, such as deferred revenue, allowance for doubtful accounts, the impact of equity awards, depreciation and amortization and employee related accruals. These differences result in deferred tax assets and liabilities, which are included on the Company's balance sheets. The Company must then assess the likelihood that its deferred tax assets will be recovered from future taxable income and to the extent the Company believes that recovery is not likely, it must establish a valuation allowance. Significant management judgment is required in determining the Company's provision for income taxes, the Company's deferred tax assets and liabilities and any valuation allowance recorded against the Company's net deferred tax assets. The Company's deferred tax assets, consisting primarily of net operating loss carryforwards, amounted to $79.2 million tax effected as of the end of 2016 . The Company has also recorded a valuation allowance of $79.2 million , tax effected, as of the end of 2016 due to uncertainties related to the Company's ability to utilize its U.S. deferred tax assets before they expire. In making such determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, ability to project future taxable income, and results of recent operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of its net recorded amount, the Company would make an adjustment to the deferred tax assets valuation allowance, which would reduce its provision for income taxes. The Company accounts for uncertainty in income taxes using a two-step approach for recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Company classifies the liability for unrecognized tax benefits as current to the extent that it anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes. Accrued interest and penalties are included within the related tax liability line in the Consolidated Balance Sheet.
Comprehensive Income (Loss)	Comprehensive Income (Loss) Comprehensive income (loss) includes all temporary changes in equity (net assets) during a period from non-owner sources. The Company's comprehensive loss equaled to net loss for all periods presented.
New Accounting Pronouncements	New Accounting Pronouncements Recently adopted accounting pronouncements: In August 2014, the Financial Accounting Standards Board or FASB issued Accounting Standards Update or ASU No. 2014-15, Presentation of Financial Statements - Going Concern (Sub Topic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern . This ASU 2014-15 provides guidance to an entity’s management with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are currently commonly provided by entities in the financial statement footnotes. This ASU 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016. The Company adopted this guidance prospectively with no material effect on the consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718) : Improvements to Employee Share-Based Payment Accounting. This update was issued as part of the FASB’s simplification initiative and affects all entities that issue share-based payment awards to their employees. The amendments in this update cover such areas as the recognition of excess tax benefits and deficiencies, the classification of those excess tax benefits on the statement of cash flows, an accounting policy election for forfeitures, the amount an employer can withhold to cover income taxes and still qualify for equity classification and the classification of those taxes paid on the statement of cash flows. The Company has decided to early adopt ASU 2016-09 in Q4 2016 and has elected to continue to estimate their forfeiture rate rather than recognizing forfeitures as they occur. The ASU 2016-09 is considered to be effective from the beginning of the year of adoption. In the year of adoption, ASU 2016-09 requires that the cumulative effect adjustment be recorded to retained earnings. Due to the full valuation allowance, there is no cumulative effect adjustment to record. Excess windfall net operating loss carryforwards are converted into deferred tax net operating losses with a corresponding increase in valuation allowance as of the beginning of 2016; the year of adoption. Recently issued accounting pronouncements not yet adopted: In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. In July 2015, the FASB approved a one-year delay in the effective date by issuing ASU 2015-09, Revenue from Contracts with customers. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The Company is currently evaluating the impact of the adoption of ASU 2014-09 on its consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the measurement of Inventory, which amends the accounting guidance on the valuation of inventory. The guidance requires an entity to measure in scope inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent measurement is unchanged for inventory measured using LIFO or the retail inventory method. The amendments do not apply to inventory that is measured using last-in, first-out (LIFO) or the retail inventory method. The amendments apply to all other inventory, which includes inventory that is measured using first-in, first-out (FIFO) or average cost. This guidance is effective for reporting periods beginning after December 15, 2016, including interim periods within those fiscal years. The Company is currently evaluating the impact of ASU 2015-11 on the consolidated financial statements and footnote disclosures. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases . The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact of our pending adoption of the new standard on the consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-08, Revenue from contracts with customers (Topic 606): Principal versus Agent Considerations Reporting Revenue Gross versus Net. The amendments are intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations by amending certain existing illustrative examples and adding additional illustrative examples to assist in the application of the guidance. The effective date and transition of these amendments is the same as the effective date and transition of ASU 2014-09. Public entities should apply the amendments in ASU 2014-09 for annual reporting periods beginning after December 15, 2017, including interim reporting periods therein (i.e., January 1, 2018, for a calendar year entity). The Company is currently evaluating the impact of our pending adoption of the new standard on the consolidated financial statements. In May 2016, the FASB issued ASU No. 2016-12, Revenue from contracts with customers (Topic 606) : Narrow Scope Improvements and Practical Expedients . This update among other things: (1) clarify the object of the collectability criterion for applying paragraph 606-10-25-7; (2) permit an entity to exclude amounts collected from customers for all sales (and other similar) taxes from transaction price; (3) specify that the measurement date for noncash consideration is contract inception; (4) provide a practical expedient that permits an entity to reflect the aggregate effect of all modifications that occur before the beginning of the earliest period presented when identifying the satisfied and unsatisfied performance obligations, determining the transaction price, and allocating the transaction price to the satisfied and unsatisfied performance obligations; (5) clarify that a completed contract for purposes of transition is a contract for which all (or substantially all) of the revenue was recognized under legacy GAAP before the date of initial application, and (6) clarify that an entity that retrospectively applies the guidance in Topic 606 to each prior period reporting is not required to disclose the effect of the accounting change for the period of adoption. This amendment is effective for public entities for annual reports beginning after December 15, 2017, including interim periods therein. For nonpublic entities one year later. The Company is currently evaluating the impact of our pending adoption of the new standard on the consolidated financial statements. In August 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-15, Statement of Cash Flows (Topic 230) : Classification of Certain Cash Receipts and Cash Payments . This update clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This ASU is effective for public business entities for fiscal years beginning after December 15, 2017, and for interim periods therein with early adoption permitted and must be applied retrospectively to all periods presented. The Company is currently evaluating the impact of our pending adoption of the new standard on the consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity transfers of assets other than inventory. This update removes the requirement under which the income tax consequences of intra-entity transfers are deferred until the assets are ultimately sold to an outside party, except for transfers of inventory. The tax consequences of such transfers would be recognized in tax expense when the transfers occur. The standard is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those annual periods. Early adoption is permitted. The Company is currently evaluating the impact of adopting this guidance on the consolidated financial statements.
Net Loss Per Share	Basic net loss per share is computed by dividing net loss available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net loss per share was computed using the weighted average number of common shares outstanding during the period plus potentially dilutive common shares outstanding during the period under the treasury stock method. In computing diluted net loss per share, the weighted average stock price for the period is used in determining the number of shares assumed to be purchased from the exercise of stock options and warrants.
