Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]	Note 1 — The Company and Basis of Presentation QuickLogic Corporation was founded in 1988 and reincorporated in Delaware in 1999. The Company provides innovative, programmable silicon and software platforms to enable its customers to develop custom hardware products in a fast time-to-market and cost-effective way. Specifically, QuickLogic is a fabless semiconductor company with a variety of products: embedded FPGA ("eFPGA") intellectual property ("IP"), low power, multi-core semiconductor system-on-chips ("SoCs"), discrete FPGAs, and AI software. QuickLogic's customers can use its eFPGA IP for hardware acceleration and pre-processing in their Application Specific Integrated Circuit ("ASIC") products, the Company's SoCs to run its customers' software and build their hardware around, and the Company's discrete FPGAs to implement their custom functionality. The Analytics Toolkit from SensiML Corporation ("SensiML"), the Company's wholly-owned subsidiary, provides an end-to-end Artificial Intelligence / Machine Learning solution with accurate sensor algorithms using AI technology. The full range of platforms, software tools, and eFPGA IP enables the practical and efficient adoption of AI, voice, and sensor processing across Aerospace and Defense, Consumer/Industrial IoT, and Consumer Electronics markets. The accompanying interim 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 (“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 unaudited condensed consolidated financial statements be read in conjunction with the Company's Form 10-K for the year ended December 31, 2023, which was filed with the Securities and Exchange Commission (“SEC”) on March 27, 2024. Operating results for the three months ended March 31, 2024 are not necessarily indicative of the results that may be expected for the full fiscal 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 quarter for 2024 and 2023 ended on March 31, 2024 and April 2, 2023, respectively. The Company has one reportable business segment based on how its Chief Operating Decision Maker ("CODM") manages the business and in a manner consistent with the internal reporting provided to the CODM. The CODM, the Company's Chief Executive Officer ("CEO"), reviews detailed income statements, balance sheets, and sales reports in order to assess performance of the Company. Sales and operating income are some of the key variables monitored by the CODM and management when determining the Company's financial condition and operating performance. *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 with Heritage Bank (the "Revolving Facility"), and cash flows from operations. As of March 31, 2024, the Company's principal sources of liquidity consisted of cash, cash equivalents and restricted cash of $27.4 million, inclusive of a $20.0 million advance from its Revolving Facility and $3.5 million in net proceeds from the Company's sale of common stock in the three months ended March 31, 2024. The Company's restricted cash balance as of March 31, 2024 was $0.1 million and relates to amounts pledged as cash security for the use of credit cards. The Company was in compliance with all the Revolving Facility loan covenants as of March 31, 2024. As of March 31, 2024, the Company had $20.0 million outstanding on the Revolving Facility with an interest rate of 9.00%. On March 13, 2024, the Company entered into common stock purchase agreements with certain institutional investors and their affiliated entities for the sale of an aggregate of 223 thousand shares of common stock, par value $0.001, in a registered direct offering, resulting in net cash proceeds of approximately $3.5 million. Issuance costs related to the offering were negligible. The purchase price for each share of common stock was $16.00. See Note 9 for additional information. On March 21, 2023, the Company entered into common stock purchase agreements with certain investors for the sale of an aggregate of 450 thousand shares of its common stock, in a registered direct offering pursuant to an effective shelf registration statement on Form S-3, resulting in net cash proceeds of approximately $2.3 million. Issuance costs related to the offering were immaterial. The purchase price for each share of common stock in the Share Placement was $5.14. On April 28, 2023, the Company converted accounts receivable for a customer in the amount of approximately $1.16 million to notes receivable (the "Note"). At the time, the Note bore an interest rate of 3.0% compounded monthly. On June 28, 2023, the Company cancelled the original note and entered into a revised promissory note with the customer, where the interest rate changed to 4.69% compounded monthly, or a 4.8% effective annual interest rate, accruing from the date of the prior note. If not prepaid prior to the Note maturity date of June 28, 2024, the principal and all accrued and unpaid interest will be due and payable to the Company. If an event of default occurs, the interest rate will increase to 10.0%. All other terms of the Note remained the same. As of March 31, 2024, the related note receivable balance was $1.21 million, including $54 thousand in accrued interest. 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 $3.5 million gross cash proceeds from the March 13, 2024 financing, its revenues from operations, and the available financial resources from the Revolving Facility with Heritage Bank will be sufficient to fund its operations and capital expenditures and provide adequate working capital for the next twelve months. 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 SoC, Quick AI solution, QuickAI™, SensiML Analytics Toolkit, Eclipse II products, and eFPGA IP license and professional services; fluctuations in revenue as a result of product end-of-life; fluctuations in revenue as a result of the stage in the product life cycle of its customers’ products; costs of securing access to and availability of adequate manufacturing capacity; levels of inventories; wafer purchase commitments; customer credit terms; the amount and timing of research and development expenditures; the timing of new product introductions; production volumes; product quality; sales and marketing efforts; the value and liquidity of its investment portfolio; changes in operating assets and liabilities; the ability to obtain or renew debt financing and to remain in compliance with the terms of existing credit facilities; the ability to raise funds from the sale of equity in the Company; the issuance and exercise of stock options and participation in the Company’s employee stock purchase plan; and other factors related to the uncertainties of the industry and global economics. Over the longer term, the Company anticipates that 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, and its ability to raise additional capital in the public capital markets will be sufficient to satisfy its operations and capital expenditures. However, the Company cannot provide any assurance that it will be able to raise additional capital, if required, or that such capital will be available on terms acceptable to the Company. The inability of the Company to generate sufficient sales from its new product offerings and/or raise additional capital if needed could have a material adverse effect on the Company’s operations and financial condition, including its ability to maintain compliance with its lender’s financial covenants. *Principles of Consolidation* The 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, and are insignificant for all periods presented. *Uses of Estimates* The preparation of these unaudited condensed 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 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 undertake in the future, actual results may ultimately materially differ from these estimates and assumptions. Areas where management uses subjective judgment include, but are not limited to, revenue recognition, inventory valuation, including the identification of excess quantities, market value, and obsolescence, and valuation of goodwill and long-lived and intangible assets. The Company believes that it applies judgments and estimates in a consistent manner and that such consistent application results in consolidated financial statements and accompanying notes that fairly represent all periods presented. However, any factual errors or errors in these judgments and estimates may have a material impact on the Company's financial statements. For additional information, please refer to the Company's most recent Annual Report on Form 10-K, which was filed with the SEC on March 27, 2024. *Concentration of Risk* The Company's accounts receivable and note 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 does not require collateral. See Note 12, Information Concerning Product Lines, Geographic Information and Revenue Concentration, for information regarding concentrations associated with accounts receivable. As of March 31, 2024 and December 31, 2023, the Company had $20.0 million of revolving debt outstanding with Heritage Bank; the revolving debt carried an interest rate of 9.00% per annum. Heritage Bank has a first priority security interest in substantially all of the Company's tangible and intangible assets to secure any outstanding amounts under the agreement. The Company was in compliance with all loan covenants under the agreement as of the end of the current reporting period. The maturity date for advances under the revolving debt agreement is December 31, 2025. At March 31, 2024, the Company had utilized a significant portion of the revolving debt, and as a result, it maintains a substantial amount of cash deposits with Heritage Bank. The concentration of cash with one financial institution poses certain risks. For instance, adverse developments affecting financial institutions, companies in the financial services industry, or the financial services industry, such as actual events or concerns involving liquidity, defaults, or non-performance, could adversely impact the stability of Heritage Bank, leading to additional financial risks for the Company. Any material decline in available funding or the Company's ability to access its cash, cash equivalents, and liquidity resources, inclusive of those at Heritage Bank, could adversely impact its ability to meet its operating expenses, financial and contractual obligations, or result in breaches of its contractual obligations. Any of these impacts could have material adverse impacts on the Company's operations and liquidity.
