Organization Consolidation And Presentation Of Financial Statements [Abstract]
The Company and Basis of Presentation	Note 1 — The Company and Basis of Presentation QuickLogic Corporation ("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 accompanying interim condensed consolidated financial statements are unaudited. In the opinion of management, these statements have been prepared in accordance with 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 31, 2017, which was filed with the Securities and Exchange Commission, or SEC, on March 9, 2018. Operating results for the three and nine-month periods ended September 30, 2018 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 the fiscal quarters each end on the Sunday closest to the end of each calendar quarter. QuickLogic's third fiscal quarters for 2018 and for 2017 ended on September 30, 2018 and October 1, 2017, respectively. Liquidity The Company has financed its operations and capital investments through sales of common stock, capital leases, and bank lines of credit. As of September 30, 2018, the Company's principal sources of liquidity consisted of cash and cash equivalents of $24.2 million and $9.0 million line of credit with Heritage Bank of Commerce (“Heritage Bank”). On September 28, 2018, the Company entered into a Loan and Security Agreement (the "Loan Agreement") with Heritage Bank. The Loan Agreement provided for, among other things, a revolving credit facility with aggregate commitments of $9,000,000 (the “Revolving Facility”). The maturity date for loans under the Revolving Facility is September 28, 2020. As of the date hereof, the Company has drawn down $9.0 million under this revolving facility. Loans under the Revolving Facility will bear interest at a rate equal to one half of one percentage point (0.50%) above the variable rate of interest, per annum, that appears in The Wall Street Journal from time to time, whether or not such announced rate is the lowest rate available from Heritage Bank. See Note 5 to Unaudited Condensed Consolidated Financial Statements for the details of the financial covenants. Company is in compliance with all loan covenants as of September 30, 2018. The Line of credit facility with Silicon Valley Bank, which matured on September 24, 2018 was fully paid off in July 2018. On May 29, 2018, the Company issued 13.5 million shares of common stock, $0.001 par value and warrants to purchases up to 5.4 million shares of common stock at a combined price of $1.15. The warrants are exercisable any time for a period of 60 months from the date of issuance on May 29, 2018, and are exercisable at a price of $1.38 per share. See Note 7 to the Unaudited Condensed Consolidated Financial Statements for more details. The Company received net proceeds of approximately $13.9 million, after deducting underwriting commissions and other offering-related expenses. The Company expects to use the net proceeds for working capital, to accelerate the development of next generation products and for general corporate purposes. The Company may also use a portion of the net proceeds to acquire and/or license technologies and acquire and/or invest in businesses when the opportunity arises; however, the Company currently has no commitments or agreements with respect to any such transactions. The shares were offered pursuant to a shelf registration statement filed on December 9, 2016 with the SEC, as amended on March 15, 2017, which was declared effective by the SEC on March 16, 2017, and as supplemented by a prospectus supplement dated May 25, 2018, which were filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended. The Company's liquidity is affected by many factors including, among others: the level of revenue and gross profit as a result of the cyclicality of the semiconductor industry; the conversion of design opportunities into revenue; market acceptance of existing and new products, including solutions based on its Sensor Processing platforms; fluctuations in revenue as a result of product end-of-life; fluctuations in revenue as a result of the stage in the product life cycle of its customers' products; costs of securing access to and availability of adequate manufacturing capacity; levels of inventories; wafer purchase commitments; customer credit terms; the amount and timing of research and development expenditures; the timing of new product introductions; production volumes; product quality; sales and marketing efforts; the value and liquidity of its investment portfolio; changes in operating assets and liabilities; the ability to obtain or renew debt financing and to remain in compliance with the terms of existing credit facilities; the ability to raise funds from the sale of equity in the Company; the issuance and exercise of stock options and participation in the Company's employee stock purchase plan; and other factors related to the uncertainties of the industry and global economics. The Company currently uses its cash to fund its capital expenditures and operations. Based on past operating performance and current annual operating plans, the Company believes that sales generated from its new product offerings, existing cash and cash equivalents, together with financial resources from its Revolving Facility with Heritage Bank and its ability to raise additional capital in the public capital markets will be sufficient to satisfy its operations and capital expenditures and provides sufficient working capital for the next twelve months from the date the unaudited condensed consolidated financial statements as of and for the three and nine-month period ended September 30, 2018. The Company cannot provide any assurance that it will be able to raise additional capital, if required, or that such capital will be available on terms acceptable to the Company. The inability of the Company to generate sufficient sales from its new product offerings and/or raise additional capital if needed could have a material adverse effect on the Company’s operations and financial condition, including its ability to maintain compliance with its lender’s financial covenants. Principles of Consolidation The consolidated financial statements 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 investments, valuation of long-lived assets including mask sets, 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 11 for information regarding concentrations associated with accounts receivable.

Principles of Consolidation

The 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 investments, valuation of long-lived assets including mask sets, 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 11 for information regarding concentrations associated with accounts receivable.
