As of January 1, 2023 The Company's principal contractual commitments include purchase obligations, re-payments of draw downs from the revolving line of credit, and payments under operating and finance leases. Purchase obligations are largely comprised of open purchase order commitments to suppliers. The Company's risk associated with the purchase obligations is limited to the termination liability provisions within those contracts, and as such, the Company does not risk. See Note 6 Heritage Bank has a first 6 On September 14, 2022 February 9, 2022, September 14, 2022 February 9, 2022 On September 22, 2021, September 30, 2021, $45 thousand in issuance costs.

Based on past performance and current expectations, the Company believes that its existing cash and cash equivalents, together with $3.2 million and $1.5 million gross cash proceeds from the September 14, 2022 February 9, 2022 twelve Various factors 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® and PolarPro® platforms, ArcticPro™, EOS S3 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 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 December 2024, 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, ("SEC"), and include the accounts of QuickLogic and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. Critical Accounting Policies and 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. Although these estimates are based on the Company’s knowledge of current events and actions it may may in regards to revenue recognition; and the valuation of inventories including identification of excess quantities, market value and obsolescence. The methods, estimates and judgments we use in applying our most critical accountin may 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 Revenue Recognition The Company recognizes revenue in accordance with Accounting Standards Codification ("ASC") Topic No. 606 The Company earns revenue from principal activities by delivering standard hardware products, eFPGA IP products, and software as a service to customers and other revenue. The Company applies a five • Identification of the contract, or contracts, with a customer, • Identification of the performance obligations in the contract, • Determination of the transaction price. T may • Allocation of the transaction price to the performance obligations in the contract, and • Recognition of revenue when, or as, we satisfy a performance obligation. As part of its assessment of each contract, the Company evaluates certain factors including the customer’s ability to pay, or credit risk. The following is a description the Company's revenue recognition policy by principal activity: Hardware Product Revenue The Company generates revenue by supplying standard hardware products, which must be programmed before they can be used in an application. Standard hardware products may third not one not eFPGA IP Revenue eFPGA IP revenue is comprised primarily of eFPGA intellectual property revenue, eFPGA-related professional services revenue, and eFPGA-related support and maintenance. The Company recognizes eFPGA intellectual property revenue from licensing its eFPGA intellectual property to customers and recognizes eFPGA-related professional services revenue from the fees associated with custom development and integration of the Company's technology solutions into hardware products. The Company recognizes eFPGA revenue from support and maintenance services for post-implementation customer support ratably over the service term. Renewals of support and maintenance contracts create new performance obligations which the Company recognizes as revenue ratably over the service term. e FPGA IP contractual arrangements often include promises to transfer intellectual property licenses, to customize hardware products, and to provide professional services and technical support services. T may not considered individual performance obligations. not Judgment is required to determine the SSP for each performance obligation. The Company rarely sell eFPGA IP on a standalone basis. Generally, the Company provides eFPGA-related professional services to customers based on unique contractual arrangement terms and conditions, with unique deliverables, often in conjunction with other performance obligations. not may may one may overall pricing objectives, taking into consideration market conditions and other factors, including the value of its contracts, type of the customer, customer tier, type of the technology used, customer demographics, geographic locations, and other factors. eparately if they are distinct. The Company allocates the transaction price to the separate performance obligations based on their relative SSP. The Company also provides eFPGA-related professional services on a time-and-material basis. The Company recognizes revenue on contracts with a customer with a single performance obligation to transfer eFPGA intellectual property when the Company transfers control to the customer, which is generally upon product delivery to the customer assuming all other criteria for revenue recognition have been met. Generally, the Company satisfies contractual performance obligations over time. When the Company satisfies performance obligations over time, it recognizes revenue by applying an over-time methodology that provides a faithful depiction of the transfer of the contractual arrangement's deliverables to the customer. These over-time methodologies may • Model measured using the input method such as units of labor, • Model measured using the input method reflecting a generally consistent effort • Model measured using the output method such as the specific deliverables produced, • Model measured using the input method such as time and material for professional engineering services provided. Due to the nature of the work performed under contractual arrangements, the estimation of the over-time model is complex and involves significant judgment. In the case of the input methods, the key factors reviewed by management to estimate costs to complete each contract is the estimated labor days-effort necessary to complete the project, budgeted hours, hourly cost to the Company, profit margins, and engineering hours at cut-off when projects extend beyond a reporting period. In the case of the output method, key factors reviewed by the Company are the specific deliverables specified in the contracts with customers. The Company has methods and controls in place for tracking labor-days incurred in completing customization and other professional services as well as quantifying changes in estimates. In the Fiscal Year ended January 2, 2022, not This deferred revenue was recognized to revenue during the year ended January 1, 2023. 8 SaaS & Other Revenue SaaS & Other revenue is comprised primarily of software as a s ervice ("SaaS") revenue, software-related professional services revenue, and royalties from licensing the Company's technology. SaaS revenue is generated when the Company licenses its software to customers and allows customers to access the software over a short-term subscription basis. The Company grants the customer the right to access and use software at the outset of the arrangement and throughout the entire term of the arrangement. The Company recognizes revenue from software-related professional services as services are provided to the customer. The Company recognizes royalty revenue on the later of (i) the subsequent sale or usage, or (ii) satisfaction of a performance obligation to which some or all of the sales-based royalty has been allocated. Practical Expedients, Elections, and Exemptions • Taxes collected from customers and remitted to government authorities and that are related to the sales of our products are excluded from revenues. • Sales commissions are expensed when incurred because the amortization period would have been one • The Company does not one Contract Balances Due to the terms in contractual agreements with customers, the timing of revenue recognition may The Company records a contract asset when revenue is recognized prior to invoicing if the Company does not not not not The Company had contract asset s of approximately $2.0 million and $0.3 million and contract liabilities (reflected as deferred revenue) of $0 and $0.3 million on the consolidated balance sheets at January 1, 2023 January 2, 2022, Assets Recognized from Costs to Obtain a Contract with a Customer The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if it expects the benefit of those costs to be longer than one none 606 January 1, 2023 January 2, 2022 no January 1, 2023, January 2, 2022. Hardware Product Sales Return Allowance The Company records an allowance for hardware product sales returns. The allowance for sales returns is based on a historical returns analysis performed on a quarterly basis. Amounts recorded for hardware product sales returns were a $13 thousand sales return reversal, and $30 thousand for the years ended January 1, 2023 January 2, 2022 January 3, 2021 on the Company's consolidated statements of operations. Cost of Revenues The Company records costs of revenue associated with hardware product revenues, eFPGA IP revenue and SaaS revenue. Hardware product costs include the cost of materials, contract manufacturing fees, shipping costs, and quality assurance. Hardware product costs also includes indirect costs such as warranty, excess and obsolete inventory charges, general overhead costs, depreciation and amortization of certain capitalized software. eFPGA IP and SaaS costs includes costs related to services under contractual agreements over the term of their respective agreements. These costs are primarily comprised of employee salary and benefits and other employee-related costs to perform work on revenue-generating contracts with customers, software tool utilization costs and contract engineering costs.

Significant Accounting Policies [Text Block]	NOTE 2 OTHER RELEVANT ACCOUNTING POLICIES Cash Equivalents and Restricted Cash The Company considers all short-term, highly liquid investments with an original or a remaining maturity at purchase of ninety Foreign Currency Transactions All of the Company’s revenue transactions and inputs to its cost of revenue are denominated in U.S. dollars. The Company conducts sales and marketing activities in various countries outside of the United States. The Company's foreign operations' monetary assets and liabilities 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. The Company's foreign operations' income and expenses are transacted in local foreign currency and translated to U.S. dollars using the average exchange rates in effect during the period. Gains and losses from the foreign currency transactions of the Company's foreign operations are recorded as interest income and other (expense) income, net in the consolidated statements of operations.

As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. Assets and liabilities recorded at fair value are measured and classified in accordance with a three • Level 1 • Level 2 not • Level 3 no The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The determination of fair value involves the use of appropriate valuation methods and relevant inputs into valuation models. The carrying value of cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to their relatively short maturities. The Company's financial assets consisting of an investment in non-marketable equity without a readily determinable fair value, are measured under a measurement election alternative to the requirement to carry equity interests at fair value. In the Fiscal Year ended January 2, 2022, no no 2013 321 3 no January 1, 2023. 8 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 seven one seven Capitalized Internal-Use Software The Company capitalizes costs related to the development of hosted services it provides to its customers and internally used enterprise-level business and finance software in support of the Company’s operational needs. Costs incurred in the application development phase are capitalized and amortized on a straight-line basis over their useful lives, which are generally five Long-Lived Assets The Company reviews the recoverability of its long-lived assets annually and when events or changes in circumstances occur that indicate that the carrying value of the asset or asset group may not The Company's long-lived assets include property and equipment. The Company assesses possible impairment based its 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, as well as the useful lives applied to the assets. 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 estima ted 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. The Company recognized gains on disposal of equipment of $27 thousand and $5 thousand in the years ended January 1, 2023 and January 2, 2022 , respectively. Allowance for Doubtful Accounts The Company estimates the amount of uncollectible accounts receivable at the end of each reporting period based on the aging of the receivable balance, current and historical customer trends, and communications with its customers. Amounts are written off only after considerable collection efforts have been made and the amounts are determined to be uncollectible. The Company provides an allowance for doubtful accounts based on both historical experience and a specific identification basis. As of January 1, 2023 January 2, 2022, January 1, 2023 January 2, 2022 Hardware Product Warranty Costs The Company warrants product hardware against defects in material and workmanship under normal use for twelve not 606. not not January 1, 2023 January 2, 2022 January 3, 2021 Leases The Company accounts for leases under ASC 842 842, 12 may not twelve The Company’s ROU assets were approximately $1.4 million and $1.5 million and lease liabilities were approximately and $1.4 million and $1.6 million on the Company’s consolidated balance sheets at January 1, 2023 January 2, 2022, 7 Business Combinations When the Company acquires a business, it allocates the purchase price to the acquired tangible assets and assumed liabilities, including deferred revenue, liabilities associated with the fair value of contingent consideration and acquired identifiable intangible assets with finite lives. Any residual purchase price is recorded as goodwill. The allocation of the purchase price requires the Company to make significant estimates in determining the fair values of these acquired assets and assumed liabilities, intangible assets with finite useful lives, and goodwill. These estimates are based on information obtained from management of the acquired companies, the Company's assessment of this information, and historical experience. These estimates can include, but are not may may may may The Company recognizes assets acquired (including goodwill and identifiable intangible assets with finite useful lives) and liabilities assumed at fair value on the acquisition date.

Advertising and promotion expense s were $40 thousand, $47 thousand and $76 thousand for the years ended January 1, 2023 January 2, 2022 January 3, 2021 Stock-Based Compensation The Company grants stock-based compensation under its stock plan (the "Plan") to eligible employees and non-employee directors and grants stock-based compensation under an employee stock purchase plan ("ESPP") for all eligible employees. 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. The fair value of restricted stock awards, restricted stock units, and performance-based restricted stock units is based on the closing price of the Company’s common stock on the date of grant. Using the Black-Scholes pricing model requires us to develop highly subjective assumptions, including the expected term of awards, expected volatility of our stock, expected risk-free interest rate and expected dividend rate over the term of the award. The expected term of awards is based primarily on our historical experience with similar grants. The expected stock price volatility for both stock options and ESPP shares is based on the historic volatility of our 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. The expected stock price volatility under the Plan and the ESPP is based on the historic volatility of our 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 appropriate for the expected term of stock awards under the Plan or the maturity appropriate for the term of the purchase period for the ESPP Plan. The dividend yield assumption is based on the Company's intent not Stock-based compensation expense is measured at the grant date based on the fair value of the award less expected forfeitures, over the requisite service period, which is typically the vesting period. Expected forfeitures are an estimate based on the historical pre-vest cancellation experience and is applied to all share-based awards. Equity compensation awards that contain a service condition are expensed using the straight-line attribution method over the req uisite service period. awards are expected to vest based on the achievement of a performance goal and are expensed over the estimated vesting period, which is estimated by management. We regularly review the assumptions used to compute the fair value of our stock-based awards and we revise our assumptions as appropriate. See Notes 11 12 Accounting for Income Taxes As part of the process of preparing our financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our 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 our balance sheets. We must then assess the likelihood that our deferred tax assets will be recovered from future taxable income. To the extent we believe that recovery is not The Company accounts for uncertainty in income taxes using a two first not second 50% one Concentrations 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.

Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value of Financial Instruments Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. Assets and liabilities recorded at fair value are measured and classified in accordance with a three • Level 1 • Level 2 not • Level 3 no The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The determination of fair value involves the use of appropriate valuation methods and relevant inputs into valuation models. The carrying value of cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to their relatively short maturities. The Company's financial assets consisting of an investment in non-marketable equity without a readily determinable fair value, are measured under a measurement election alternative to the requirement to carry equity interests at fair value.

The Company assesses possible impairment based its 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, as well as the useful lives applied to the assets. 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 estima ted 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. The Company recognized gains on disposal of equipment of $27 thousand and $5 thousand in the years ended January 1, 2023 and January 2, 2022 , respectively.
Accounts Receivable [Policy Text Block]	Allowance for Doubtful Accounts The Company estimates the amount of uncollectible accounts receivable at the end of each reporting period based on the aging of the receivable balance, current and historical customer trends, and communications with its customers.

Business Combinations Policy [Policy Text Block]	Business Combinations When the Company acquires a business, it allocates the purchase price to the acquired tangible assets and assumed liabilities, including deferred revenue, liabilities associated with the fair value of contingent consideration and acquired identifiable intangible assets with finite lives. Any residual purchase price is recorded as goodwill. The allocation of the purchase price requires the Company to make significant estimates in determining the fair values of these acquired assets and assumed liabilities, intangible assets with finite useful lives, and goodwill. These estimates are based on information obtained from management of the acquired companies, the Company's assessment of this information, and historical experience. These estimates can include, but are not may may may may The Company recognizes assets acquired (including goodwill and identifiable intangible assets with finite useful lives) and liabilities assumed at fair value on the acquisition date.

Share-Based Payment Arrangement [Policy Text Block]	Stock-Based Compensation The Company grants stock-based compensation under its stock plan (the "Plan") to eligible employees and non-employee directors and grants stock-based compensation under an employee stock purchase plan ("ESPP") for all eligible employees. 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. The fair value of restricted stock awards, restricted stock units, and performance-based restricted stock units is based on the closing price of the Company’s common stock on the date of grant. Using the Black-Scholes pricing model requires us to develop highly subjective assumptions, including the expected term of awards, expected volatility of our stock, expected risk-free interest rate and expected dividend rate over the term of the award. The expected term of awards is based primarily on our historical experience with similar grants. The expected stock price volatility for both stock options and ESPP shares is based on the historic volatility of our 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. The expected stock price volatility under the Plan and the ESPP is based on the historic volatility of our 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 appropriate for the expected term of stock awards under the Plan or the maturity appropriate for the term of the purchase period for the ESPP Plan. The dividend yield assumption is based on the Company's intent not Stock-based compensation expense is measured at the grant date based on the fair value of the award less expected forfeitures, over the requisite service period, which is typically the vesting period. Expected forfeitures are an estimate based on the historical pre-vest cancellation experience and is applied to all share-based awards. Equity compensation awards that contain a service condition are expensed using the straight-line attribution method over the req uisite service period. awards are expected to vest based on the achievement of a performance goal and are expensed over the estimated vesting period, which is estimated by management. We regularly review the assumptions used to compute the fair value of our stock-based awards and we revise our assumptions as appropriate. See Notes 11 12
Income Tax, Policy [Policy Text Block]	Accounting for Income Taxes As part of the process of preparing our financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our 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 our balance sheets. We must then assess the likelihood that our deferred tax assets will be recovered from future taxable income. To the extent we believe that recovery is not The Company accounts for uncertainty in income taxes using a two first not second 50% one
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentrations 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.

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.
