Organization Consolidation And Presentation Of Financial Statements [Abstract]
The Company and Basis of Presentation	Note 1 — The Company and Basis of Presentation QuickLogic Corporation, or QuickLogic or 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, Hearable, 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. The Company’s wholly owned subsidiary, SensiML Corporation, or SensiML, provides Analytics Toolkit, which is used in many of the applications where the Company’s ArcticPro™, eFPGA intellectual property, or IP plays a critical role. SensiML Analytics toolkit is an end-to-end software suite that provides OEMs a straightforward process for developing pattern matching sensor algorithms using machine learning technology that are optimized for ultra-low power consumption. The accompanying interim unaudited condensed consolidated financial statements are unaudited. In the opinion of the Company’s management, these statements have been prepared in accordance with the United States generally accepted accounting principles, or U.S. GAAP, and include all adjustments, consisting only of normal recurring adjustments, necessary to provide a fair statement of results for the interim periods presented. The Company recommends that these interim condensed consolidated financial statements be read in conjunction with the Company's Form 10-K for the year ended December 29, 2019, which was filed with the Securities and Exchange Commission, or SEC, on March 13, 2020. Operating results for the three months ended March 29, 2020 are not necessarily indicative of the results that may be expected for the full year. QuickLogic's fiscal year ends on the Sunday closest to December 31 and each fiscal quarter ends on the Sunday closest to the end of each calendar quarter. QuickLogic's first fiscal quarters for 2020 and for 2019 ended on March 29, 2020 and March 31, 2019, respectively. COVID-19 Risks and Uncertainties On January 30, 2020, the World Health Organization (“WHO”) declared a global emergency due to the COVID-19 pandemic, and on February 28, 2020, the WHO raised its assessment of the threat from high to very high at a global level. The outbreak has resulted in significant governmental measures being implemented to control the spread of COVID-19, including, among others, restrictions on travel, business operations and the movement of people in many regions of the world in which the Company operates, and the imposition of shelter-in-place or similarly restrictive work-from-home orders impacting many of the Company’s offices and employees, including those located in the United States. As a result, the Company has temporarily closed or substantially limited the presence of personnel in its offices in several impacted locations, implemented travel restrictions and withdrawn from various industry events. The impact of the Company’s work-from-home policy that was implemented to protect its global workforce has contributed to delays in certain operational processes, including its routine quarterly financial statement close process for the first quarter of fiscal 2020. The Company has also experienced some disruption and delays in its supply chain, customer deployment plans, and logistics challenges, including certain limitations on its ability to access customer fulfilment and service sites. The COVID-19 pandemic and its potential effects on the Company’s business in its fiscal 2020 remain dynamic, and the broader implications for its business and results of operations remain uncertain. These implications could include further disruptions or restrictions on the Company’s ability to source, manufacture or distribute its products, including temporary disruptions to the facilities of its contract manufacturers in China, Taiwan, Philippines and Singapore, or the facilities of its suppliers and their contract manufacturers globally. Additionally, multiple countries have imposed and may further impose restrictions on business operations and movement of people and products to limit the spread of COVID-19. Delays in production or delivery of components or raw materials that are part of the Company’s global supply chain due to restrictions imposed to limit the spread of COVID-19 could delay or inhibit its ability to obtain the supply of components and finished goods. If COVID-19 becomes more prevalent in the locations where the Company, its customers or suppliers conduct business, or the Company experiences more pronounced disruptions in its operations, the Company may experience constrained supply or curtailed demand that may materially adversely impact its business and results of operations. In addition, any other widespread health crisis that could adversely affect global and regional economies, financial markets and overall demand environment for the Company's products could have a material adverse effect on the Company’s business, cash flows or results of operations. Liquidity The Company has financed its operations and capital investments through sales of common stock, finance and operating leases, a revolving line of credit and cash flows from operations. As of March 29, 2020, the Company's principal sources of liquidity consisted of cash and cash equivalents and restricted cash of $19.0 million, including $15.0 million drawn down from its revolving line of credit, or Revolving Facility with Heritage Bank of Commerce, or Heritage Bank. On November 6, 2019 the Company entered into a First Amendment to the Revolving Facility with Heritage Bank to extend the maturity date for one year through September 28, 2021. Under this amendment the Revolving Facility advances shall bear interest, on the outstanding daily balance thereof, at a rate per annum equal to the greater of (i) one half of one percentage point (0.50%) above the Prime Rate, or (ii) five and one half of one percentage points (5.50%). On May 6, 2020 we entered into a loan agreement with Heritage Bank for a loan of $1.2 million . See Note 18 to the Unaudited Consolidated Financial Statements for the details Various factors can affect the Company’s liquidity, 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 ® ® Over the longer term, the Company anticipates that sales generated from its new product offerings, existing cash and cash equivalents, together with financial resources from its Revolving Facility with the Heritage Bank, assuming renewal of the Revolving Facility 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 2021, 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. Reverse Stock Split Effective on December 23, 2019, the Company enacted a 1-for-14 reverse stock split of its outstanding common stock, in which, every 14 issued and outstanding shares of common stock of the Company were automatically combined into one issued and outstanding share of common stock without any change in the par value per share. Stockholders who would have otherwise been entitled to fractional shares of common stock as a result of the reverse stock split received a cash payment in lieu of receiving fractional shares. All share, equity awards, and per share amounts contained in this Form 10-Q and the accompanying Condensed Consolidated Financial Statements have been adjusted to reflect the reverse stock split for all prior periods presented. Warrants issued in connection with the May 2018 stock issuance were also adjusted to reflect the reverse stock split for all periods presented. Principles of Consolidation The unaudited condensed consolidated financial statements 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 unaudited condensed consolidated statements of operations. Uses 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 materially from those estimates, particularly in relation to revenue recognition, the allowance for doubtful accounts, sales returns, valuation of long-lived assets including mask sets, valuation of goodwill, capitalized internal-use software and related amortizable lives and intangibles related to the acquisition of SensiML, including the estimated useful lives of acquired intangible 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. Contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. Judgment is required to determine the Stand-alone Selling Price, or SSP, for each distinct performance obligation. The Company uses a range of amounts to estimate SSP when each of the products and services are sold separately and determines the discount to be allocated based on the relative SSP of the various products and services when products and services sold are bundled. In instances where SSP is not directly observable, such as when the Company does not sell the product or service separately, it determines the SSP using information that may include market conditions and other observable inputs. The Company typically has more than one SSP for individual products and services due to the stratification of those products and services by customers. In these instances, the Company may use information such as the size of the customer, customer tier, type of the technology used, customer demographics, geographic region and other factors in determining the SSP. 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 14 for information regarding concentrations associated with accounts receivable.

Accounting Policies [Abstract]
Significant Accounting Policies	Note 2 — Significant Accounting Policies During the three-month period ended March 29, 2020, there were no changes in the Company's significant accounting policies from its disclosures in the Annual Report on Form 10-K for the year ended December 29, 2019, except for the new accounting standards adopted during the three months ended March 29, 2020. For a discussion of the significant accounting policies, please see the Annual Report on Form 10-K for the fiscal year ended December 29, 2019, filed with the SEC on March 13, 2020. For a discussion of the new accounting standards adopted during the three months of 2020, see “New Accounting Pronouncements” below. Revenue Recognition The Company applies Accounting Standards Codification, or ASC, Topic 606, Revenue from Contracts with Customers , to recognize revenue. The guidance states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Under the new standard revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration it expects to receive in exchange for those products or services. The Company determines revenue recognition through the following steps: • Identification of the contract, or contracts, with a customer; • Identification of the performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contract; and • Recognition of revenue when, or as, a performance obligation is satisfied. As part of its assessment of each contract, the Company evaluates certain factors including the customer’s ability to pay, or credit risk. For each contract, the Company considers the promise to transfer products, each of which is distinct, to be the identified performance obligations. In determining the transaction price, the price stated on the purchase order is typically fixed and represents the net consideration to which the Company expects to be entitled, and therefore there is no variable consideration. As the Company’s standard payment terms are less than one year, the Company has elected, as a practical expedient, to not assess whether a contract has a significant financing component. The Company allocates the transaction price to each distinct product based on its relative stand-alone selling price. The product price as specified on the purchase order is considered the stand-alone selling price as it is an observable source that depicts the price as if sold to a similar customer in similar circumstances. Leases The Company applies Accounting Standards Update, or ASU, No. 2016-02, Leases (Topic 842) . ROU assets represent the Company’s right to use an underlying asset during the reasonably certain lease terms and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The Company primarily uses its incremental borrowing rate, based on the information available at commencement date, in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments related to initial direct cost and prepayments and excludes lease incentives. Lease expense is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. As of March 29, 2020, the Company’s right-of-use assets was approximately $2.4 million and lease liability was approximately $2.4 million as presented on the Company’s Consolidated Balance Sheet. See Note 8 to the Unaudited Consolidated Financial Statements for more details. Business Combinations The Company recognizes assets acquired (including goodwill and identifiable intangible assets) and liabilities assumed at fair value on the acquisition date. Subsequent changes to the fair value of such assets acquired and liabilities assumed are recognized in earnings, after the expiration of the measurement period, a period not to exceed 12 months from the acquisition date. Acquisition-related expenses and acquisition-related restructuring costs are recognized in earnings in the period in which they are incurred Goodwill and Intangible Assets Goodwill represents the excess fair value of consideration transferred over the fair value of net assets acquired in business combinations. The carrying value of goodwill and indefinite lived intangible assets are not amortized, but are annually tested for impairment and more often if there is an indicator of impairment. Company recognized goodwill of $185,000 due to tax benefits that arose from intangible assets acquired in the SensiML acquisition . Intangible assets with finite useful lives are amortized on a straight-line basis over the periods benefited. The Company reviews the recoverability of its long-lived assets 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 such asset, an impairment loss is recognized for the difference between estimated fair value and carrying value. The measurement of impairment requires management to estimate future cash flows and the fair value of long-lived assets. No impairment has been recognized to-date. Restricted cash Restricted cash represents amounts pledged as cash security related to the use of credit cards. New Accounting Pronouncements Recently adopted accounting pronouncements: In August 2018, the Financial Accounting Standards Board, or FASB, issued ASU, No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementations Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. For all other entities, the effective date is fiscal years beginning after December 15, 2021. In June 2016, FASB issued ASU No. 2016-13, or ASU 2016-13, "Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" New accounting pronouncements not yet adopted: In December 2019, the FASB issued ASU No. 2019-2, Simplifying the Accounting for Income Taxes

Net Loss Per Share

Net Loss Per Share	3 Months Ended
	Mar. 29, 2020
Earnings Per Share [Abstract]
Net Loss Per Share	Note 3 — Net Loss Per Share Basic 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 the three months ended March 29, 2020 and March 31, 2019, 699,000 and 597,000 shares of common stock, respectively, associated with equity awards and the estimated number of shares to be purchased under the current offering period of the 2009 Employee Stock Purchase Plan were outstanding. These shares were not included in the computation of diluted net loss per share as they were considered anti-dilutive due to the net losses the Company experienced during these periods. Warrants to purchase up to 386,100 shares were issued in connection with May 29, 2018 stock offering were also not included in the diluted loss per share calculation of the three months ended March 29, 2020 as they were also considered anti-dilutive due to the net loss the Company experienced during these periods. All shares, equity awards, and per share amounts have been adjusted to reflect the 1-for-14 reverse stock split of the Company’s outstanding common stock for all periods presented.

Income Tax Disclosure [Abstract]
Income Taxes	Note 13 — Income Taxes The Company recorded a net income tax expense of approximately $18,000 and benefit of $268,000 for the three months ended March 29, 2020 and March 31, 2019, respectively. A majority of the income tax expense for the first quarter of 2020 relates to the Company's foreign subsidiaries, which are cost-plus entities. A majority of the income tax benefit for the quarter ended March 31, 2019 relates to the deferred tax benefit arising from Intangible assets acquired from the acquisition of SensiML, which was offset by the income taxes from the Company's foreign subsidiaries, which are cost-plus entities. The Company believes it is more likely than not that federal and state net deferred tax assets will not be fully realized. In assessing the realizability of deferred tax assets, the Company’s management considers whether it is more likely than not that some portion or all of our deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. A valuation allowance is recorded for loss carryforwards and other deferred tax assets where it is more likely than not that such deferred tax assets will not be realized. Accordingly, the Company continues to maintain a valuation allowance against all of U.S. and certain foreign net deferred tax assets as of March 29, 2020. The Company continues to maintain a full valuation allowance against net federal, state and certain foreign deferred tax assets until there is sufficient evidence to support recoverability of the Company’s deferred tax assets. The Company had no unrecognized tax benefits as of March 29, 2020 and December 31, 2019, which would affect the Company's effective tax rate. The Company does not anticipate any material changes to its unrecognized tax benefits during the next 12 months. Accrued interest and penalties related to unrecognized tax benefits are recognized as part of the income tax provision in the condensed consolidated statements of operations. 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. The U.S. tax years from 1999 forward remain effectively open to examination due to the carryover of unused net operating losses and tax credits. 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. On March 27, 2020, the “Coronavirus Aid, Relief and Economic Security (“CARES”) Act was signed into law and GAAP requires recognition of the tax effects of new legislation during the reporting period that includes the enacted date. The CARES Act includes provisions relating to refundable payroll tax credits, deferment of the employer portion of certain payroll taxes, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. The Company is currently analysing the impact of these changes and therefore an estimate of the impact to income taxes is not yet available. The Company will continue to make and refine the calculations as additional analysis is completed.

COVID-19 Risks and Uncertainties	On January 30, 2020, the World Health Organization (“WHO”) declared a global emergency due to the COVID-19 pandemic, and on February 28, 2020, the WHO raised its assessment of the threat from high to very high at a global level. The outbreak has resulted in significant governmental measures being implemented to control the spread of COVID-19, including, among others, restrictions on travel, business operations and the movement of people in many regions of the world in which the Company operates, and the imposition of shelter-in-place or similarly restrictive work-from-home orders impacting many of the Company’s offices and employees, including those located in the United States. As a result, the Company has temporarily closed or substantially limited the presence of personnel in its offices in several impacted locations, implemented travel restrictions and withdrawn from various industry events. The impact of the Company’s work-from-home policy that was implemented to protect its global workforce has contributed to delays in certain operational processes, including its routine quarterly financial statement close process for the first quarter of fiscal 2020. The Company has also experienced some disruption and delays in its supply chain, customer deployment plans, and logistics challenges, including certain limitations on its ability to access customer fulfilment and service sites. The COVID-19 pandemic and its potential effects on the Company’s business in its fiscal 2020 remain dynamic, and the broader implications for its business and results of operations remain uncertain. These implications could include further disruptions or restrictions on the Company’s ability to source, manufacture or distribute its products, including temporary disruptions to the facilities of its contract manufacturers in China, Taiwan, Philippines and Singapore, or the facilities of its suppliers and their contract manufacturers globally. Additionally, multiple countries have imposed and may further impose restrictions on business operations and movement of people and products to limit the spread of COVID-19. Delays in production or delivery of components or raw materials that are part of the Company’s global supply chain due to restrictions imposed to limit the spread of COVID-19 could delay or inhibit its ability to obtain the supply of components and finished goods. If COVID-19 becomes more prevalent in the locations where the Company, its customers or suppliers conduct business, or the Company experiences more pronounced disruptions in its operations, the Company may experience constrained supply or curtailed demand that may materially adversely impact its business and results of operations. In addition, any other widespread health crisis that could adversely affect global and regional economies, financial markets and overall demand environment for the Company's products could have a material adverse effect on the Company’s business, cash flows or results of operations.
Liquidity	Liquidity The Company has financed its operations and capital investments through sales of common stock, finance and operating leases, a revolving line of credit and cash flows from operations. As of March 29, 2020, the Company's principal sources of liquidity consisted of cash and cash equivalents and restricted cash of $19.0 million, including $15.0 million drawn down from its revolving line of credit, or Revolving Facility with Heritage Bank of Commerce, or Heritage Bank. On November 6, 2019 the Company entered into a First Amendment to the Revolving Facility with Heritage Bank to extend the maturity date for one year through September 28, 2021. Under this amendment the Revolving Facility advances shall bear interest, on the outstanding daily balance thereof, at a rate per annum equal to the greater of (i) one half of one percentage point (0.50%) above the Prime Rate, or (ii) five and one half of one percentage points (5.50%). On May 6, 2020 we entered into a loan agreement with Heritage Bank for a loan of $1.2 million . See Note 18 to the Unaudited Consolidated Financial Statements for the details Various factors can affect the Company’s liquidity, 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 ® ® Over the longer term, the Company anticipates that sales generated from its new product offerings, existing cash and cash equivalents, together with financial resources from its Revolving Facility with the Heritage Bank, assuming renewal of the Revolving Facility 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 2021, 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.
Reverse Stock Split	Reverse Stock Split Effective on December 23, 2019, the Company enacted a 1-for-14 reverse stock split of its outstanding common stock, in which, every 14 issued and outstanding shares of common stock of the Company were automatically combined into one issued and outstanding share of common stock without any change in the par value per share. Stockholders who would have otherwise been entitled to fractional shares of common stock as a result of the reverse stock split received a cash payment in lieu of receiving fractional shares. All share, equity awards, and per share amounts contained in this Form 10-Q and the accompanying Condensed Consolidated Financial Statements have been adjusted to reflect the reverse stock split for all prior periods presented. Warrants issued in connection with the May 2018 stock issuance were also adjusted to reflect the reverse stock split for all periods presented.
Principles of Consolidation	Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of QuickLogic and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated.
Foreign Currency	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 unaudited condensed consolidated statements of operations.
Uses of Estimates	Uses 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 materially from those estimates, particularly in relation to revenue recognition, the allowance for doubtful accounts, sales returns, valuation of long-lived assets including mask sets, valuation of goodwill, capitalized internal-use software and related amortizable lives and intangibles related to the acquisition of SensiML, including the estimated useful lives of acquired intangible 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. Contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. Judgment is required to determine the Stand-alone Selling Price, or SSP, for each distinct performance obligation. The Company uses a range of amounts to estimate SSP when each of the products and services are sold separately and determines the discount to be allocated based on the relative SSP of the various products and services when products and services sold are bundled. In instances where SSP is not directly observable, such as when the Company does not sell the product or service separately, it determines the SSP using information that may include market conditions and other observable inputs. The Company typically has more than one SSP for individual products and services due to the stratification of those products and services by customers. In these instances, the Company may use information such as the size of the customer, customer tier, type of the technology used, customer demographics, geographic region and other factors in determining the SSP.
Concentration of Risk	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 14 for information regarding concentrations associated with accounts receivable.
Revenue Recognition	Revenue Recognition The Company applies Accounting Standards Codification, or ASC, Topic 606, Revenue from Contracts with Customers , to recognize revenue. The guidance states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Under the new standard revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration it expects to receive in exchange for those products or services. The Company determines revenue recognition through the following steps: • Identification of the contract, or contracts, with a customer; • Identification of the performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contract; and • Recognition of revenue when, or as, a performance obligation is satisfied. As part of its assessment of each contract, the Company evaluates certain factors including the customer’s ability to pay, or credit risk. For each contract, the Company considers the promise to transfer products, each of which is distinct, to be the identified performance obligations. In determining the transaction price, the price stated on the purchase order is typically fixed and represents the net consideration to which the Company expects to be entitled, and therefore there is no variable consideration. As the Company’s standard payment terms are less than one year, the Company has elected, as a practical expedient, to not assess whether a contract has a significant financing component. The Company allocates the transaction price to each distinct product based on its relative stand-alone selling price. The product price as specified on the purchase order is considered the stand-alone selling price as it is an observable source that depicts the price as if sold to a similar customer in similar circumstances.
Leases	Leases The Company applies Accounting Standards Update, or ASU, No. 2016-02, Leases (Topic 842) . ROU assets represent the Company’s right to use an underlying asset during the reasonably certain lease terms and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The Company primarily uses its incremental borrowing rate, based on the information available at commencement date, in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments related to initial direct cost and prepayments and excludes lease incentives. Lease expense is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. As of March 29, 2020, the Company’s right-of-use assets was approximately $2.4 million and lease liability was approximately $2.4 million as presented on the Company’s Consolidated Balance Sheet. See Note 8 to the Unaudited Consolidated Financial Statements for more details.
Business Combinations	Business Combinations The Company recognizes assets acquired (including goodwill and identifiable intangible assets) and liabilities assumed at fair value on the acquisition date. Subsequent changes to the fair value of such assets acquired and liabilities assumed are recognized in earnings, after the expiration of the measurement period, a period not to exceed 12 months from the acquisition date. Acquisition-related expenses and acquisition-related restructuring costs are recognized in earnings in the period in which they are incurred
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess fair value of consideration transferred over the fair value of net assets acquired in business combinations. The carrying value of goodwill and indefinite lived intangible assets are not amortized, but are annually tested for impairment and more often if there is an indicator of impairment. Company recognized goodwill of $185,000 due to tax benefits that arose from intangible assets acquired in the SensiML acquisition . Intangible assets with finite useful lives are amortized on a straight-line basis over the periods benefited. The Company reviews the recoverability of its long-lived assets 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 such asset, an impairment loss is recognized for the difference between estimated fair value and carrying value. The measurement of impairment requires management to estimate future cash flows and the fair value of long-lived assets. No impairment has been recognized to-date.
Restricted cash	Restricted cash Restricted cash represents amounts pledged as cash security related to the use of credit cards.
New Accounting Pronouncements	New Accounting Pronouncements Recently adopted accounting pronouncements: In August 2018, the Financial Accounting Standards Board, or FASB, issued ASU, No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementations Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. For all other entities, the effective date is fiscal years beginning after December 15, 2021. In June 2016, FASB issued ASU No. 2016-13, or ASU 2016-13, "Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" New accounting pronouncements not yet adopted: In December 2019, the FASB issued ASU No. 2019-2, Simplifying the Accounting for Income Taxes
Net Loss Per Share	Basic 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.
