Notes to Financial Statements
Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]	1 THE COMPANY AND BASIS OF PRESENTATION QuickLogic Corporation was founded in 1988 1999. QuickLogic’s Fiscal Year ends on the Sunday closest to December 31. 2023 , 2022 , and 2021 December 31, 2023 , January 1, 2023 , and January 2, 2022 , respectively. The Company has one Liquidity The Company has financed its operations and capital investments through the sale of common stock, financing arrangements, operating leases, a revolving line of credit, and cash flows from operations. As of December 31, 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 arrangements. 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 7 Heritage Bank has a first 7 On March 21, 2023 3, On September 14, 2022 February 9, 2022 3, September 14, 2022 February 9, 2022 On September 22, 2021 September 30, 2021 3. 11 The Company currently uses its cash to fund its working capital, to accelerate the development of next-generation products and for general corporate purposes. Based on past performance and current expectations, the Company believes that its existing cash and cash equivalents, together with $2.3 million gross cash proceeds from the March 21, 2023 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 the Company's 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 on December 31, 2025 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 and the disclosures of commitments and contingencies at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The methods, estimates, and judgments the Company uses in applying its most critical accounting policies have a significant impact on the results it reports in its consolidated financial statements. The SEC has defined critical accounting policies as those that are most important to the portrayal of the Company's financial condition and results of operations and requires it to make its most difficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. Although these estimates are based on the Company’s knowledge of current events and actions it may may not may Revenue Recognition The Company recognizes revenue in accordance with Accounting Standards Codification ("ASC") Topic 606 The Company earns revenue from principal activities by (i) delivering standard hardware products, (ii) delivering and providing eFPGA IP products and professional services, (iii) and providing software as a service to customers, as well as (iv) other miscellaneous revenue. In accordance with ASC 606, five 1. Identification of the contract, or contracts, with a customer, 2. Identification of the performance obligations in the contract, 3. Determination of the transaction price. The Company estimates the transaction price based on the amount expected to be received for transferring the performance obligations in the contract, which may 4. Allocation of the transaction price to the performance obligations in the contract, and 5. Recognition of revenue when, or as, the Company satisfies a performance obligation. When entering into a new contract, the Company evaluates certain factors including the customer’s ability to pay, or credit risk. The following is a description of 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 not one not Hardware Product Sales Return Allowance While the terms and conditions of the sale of hardware products generally do not four Amounts recorded for hardware product sales returns were $2 thousand and a sales return reversal of $13 thousand for the years ended December 31, 2023 January 1, 2023 January 2, 2022 on the Company's consolidated statements of operations. not may may eFPGA IP Revenue eFPGA IP revenue is comprised of eFPGA intellectual property revenue, eFPGA-related professional services revenue, and eFPGA-related support and maintenance revenue. 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 the 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 for which the Company recognizes as revenue ratably over the service term. The majority of the Company's revenue is derived from sales of eFPGA IP licenses and professional services. eFPGA IP contractual arrangements often include promises to transfer intellectual property licenses, to customize hardware products, and to provide professional services and technical support services. The Company must determine whether the promised goods and services are distinct performance obligations that should be accounted for separately or are a single, combined performance obligation and should be accounted for together. In accordance with ASC 606, Additionally, judgment is required by management to allocation the transaction price to the separately identifiable performance obligations in the contract. The Company allocates the transaction price of the contract to each performance obligation based on its relative SSP. The Company rarely sells eFPGA intellectual property licenses on a standalone basis. Generally, the Company will provide eFPGA-related professional services and support and maintenance services to customers in conjunction with eFPGA IP licenses based on unique contractual arrangement terms and conditions. As such, the Company is required to estimate the SSP for each performance obligation. In instances where the SSP is not not not In other instances, the Company may one may Generally, the Company satisfies eFPGA-related contractual performance obligations over time as the customer simultaneously receives and consumes the benefits provided by the Company’s performance as it performs, the Company's performance creates or enhances an asset that the customer controls as it is created or enhanced, or the Company’s performance does not The Company’s over-time methodologies include, but are not • Revenue recognition model measured using an input method such as units of labor, • Revenue recognition model measured using an output method reflecting a generally consistent effort to satisfy performance obligations throughout the contractual arrangement term, • Revenue recognition model measured using an output method such as the specific deliverables produced, • Revenue recognition model measured using an input method such as time and material for professional engineering services. For revenue derived from time and material inputs, the Company estimates a fully-burdened overhead rate for the labor and any materials required. Due to the nature of the work performed under contractual arrangements, the selection and application of an over-time methodology is complex and involves significant judgment. In the case of the selection of an input method, the key factors reviewed by management to estimate costs to complete each contract include, but are not not When the expected consideration from a revenue contract with a customer is less than the expected costs of fulfilling the contract, the Company is required to first SaaS & Other Revenue SaaS & Other Revenue is comprised primarily of software as a service ("SaaS") revenue and software-related professional services revenue. 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 SaaS revenue ratably over the license term. The Company recognizes revenue from software-related professional services as services are provided to the customer. Other miscellaneous revenue is comprised primarily of royalties from licensing the Company’s technology. 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 the Company's products are excluded from revenues. • Sales commissions are expensed when incurred because the amortization period would have been one • The Company does not one Valuation of Inventories Hardware product inventories are stated at the lower of standard cost or net realizable value.

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 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, not January 1, 2023. In determining the fair value of the investment at acquisition of the common stock, the Company applied the Black-Scholes Option Pricing model using a back-solve technique and applied significant judgment to quantify inputs used in the model, in accordance with the AICPA Accounting and Valuation Guide, Valuation of Privately Held Company Equity Securities Issued as Compensation ( 2013 321, 3 December 31, 2023 January 1, 2023. 9 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 include indirect costs such as warranty, excess and obsolete inventory charges, general overhead costs, and depreciation and amortization of certain capitalized software. eFPGA IP and SaaS costs include 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.

Advertising and promotion expense s were $44 thousand, $40 thousand, and $47 thousand for the years ended December 31, 2023 January 1, 2023 January 2, 2022 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 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 expected term of awards is based primarily on the Company's historical experience with similar grants. The expected stock price volatility for both stock options and ESPP shares is based on the historic 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 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. The Company regularly reviews the assumptions used to compute the fair value of its stock-based awards and it revises its assumptions as appropriate. See Notes 11 12 Interest Income The Company's interest income is comprised of interest earned on its money market accounts and financing receivables. As of December 31, 2023, one 9 Accounting for Income Taxes As part of the process of preparing the Company's financial statements, the Company is required to estimate its income taxes in each of the jurisdictions in which it 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. To the extent the Company believes that recovery is not The Company accounts for uncertainty in income taxes using a two first not second 50% one Comprehensive Income (Loss) The net income (loss) in the consolidated statements of operations for each of the years ended December 31, 2023 January 1, 2023 January 2, 2022 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. Cash and cash equivalents are maintained with high-quality institutions. The Company’s accounts receivables 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 ollateral. See Note 14 The Company depends on a limited number of contract manufacturers, subcontractors, and suppliers for wafer fabrication, assembly, programming and testing of its hardware products and for the supply of programming equipment. These services are typically provided by one supplier for each of the Company’s hardware products. The Company generally purchases these single or limited source services through standard purchase orders. Since 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. 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.

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. In the Fiscal Year ended January 2, 2022, not January 1, 2023.

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 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 expected term of awards is based primarily on the Company's historical experience with similar grants. The expected stock price volatility for both stock options and ESPP shares is based on the historic 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 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. The Company regularly reviews the assumptions used to compute the fair value of its stock-based awards and it revises its assumptions as appropriate. See Notes 11 12

Income Tax, Policy [Policy Text Block]	Accounting for Income Taxes As part of the process of preparing the Company's financial statements, the Company is required to estimate its income taxes in each of the jurisdictions in which it 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.

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. Cash and cash equivalents are maintained with high-quality institutions. The Company’s accounts receivables 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 ollateral. See Note 14 The Company depends on a limited number of contract manufacturers, subcontractors, and suppliers for wafer fabrication, assembly, programming and testing of its hardware products and for the supply of programming equipment. These services are typically provided by one supplier for each of the Company’s hardware products. The Company generally purchases these single or limited source services through standard purchase orders. Since 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.
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.
