Organization, Consolidation and Presentation of Financial Statements [Abstract]
THE COMPANY AND BASIS OF PRESENTATION	THE COMPANY AND BASIS OF PRESENTATION QuickLogic Corporation, ("QuickLogic", 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. QuickLogic's fiscal year ends on the Sunday closest to December 31. Fiscal years 2017, 2016 and 2015 ended on December 31, 2017, January 1, 2017 and January 3, 2016, respectively. Liquidity The Company has financed its operations and capital investments through sales of common stock, capital and operating leases, and bank lines of credit. As of December 31, 2017, the Company's principal sources of liquidity consisted of its cash and cash equivalents of $16.5 million and an additional $6.0 million credit line is available for draw at the Company's election upon credit approval under its revolving line of credit arrangement with Silicon Valley Bank. The revolving line of credit will expire in September 2018 and the Company would need to renew this line of credit or find an alternative lender prior to the expiration date. Further, any violations of debt covenants during 2018 will restrict the Company’s access to any additional cash draws from the revolving line of credit, and may require immediate repayment of the outstanding debt amounts. Additionally, the Company has an accumulated deficit of approximately $254 million, has experienced net losses in the past years and expects such losses to continue through at least the end of fiscal year 2018 as the Company continues to develop new products, applications and technologies. On August 31, 2017, the Company entered into a Fourth Amendment to the Third Amended and Restated Loan and Security Agreement with Silicon Valley Bank to extend the line of credit for one year through September 24, 2018 and to modify certain financial covenants. This amendment requires the Company to maintain (i) unrestricted cash or cash equivalents at the Silicon Valley Bank or at any of its affiliates at all times in an amount of at least $6,000,000; and (ii) a ratio of quick assets of at least 1.40 to 1.00, tested as of the last day of each month, with the numerator equal to quick assets and (a) the denominator equal to the sum of (1) current liabilities minus (2) the current portion of deferred revenue plus (3) the long term obligations. The Company is in compliance with all loan covenants as of the end of the current reporting period. As of December 31, 2017, we had $6.0 million of outstanding revolving line of credit with an interest rate of 4.31%. See Note 5 for more details. On March 28, 2017, the Company issued 11.3 million shares of common stock at a price of $1.50 per share, $0.001 par value. The Company received net proceeds of approximately $15.2 million, after deducting underwriting commissions and other offering-related expenses. The Company uses 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 and are not involved in any negotiations 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 March 23, 2017, which were filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended. The Company currently uses its cash to fund its capital expenditures and operating losses. Based on past performance and current expectations, the Company believes that its existing cash and cash equivalents, together with available financial resources from the revolving line of credit with Silicon Valley Bank will be sufficient to fund its operations and capital expenditures and provide adequate working capital for the next twelve months. The Company’s revolving line of credit with Silicon Valley Bank will expire in September 2018 and the Company would need to renew this line of credit or find an alternative lender prior to the expiration date. Further, any violations of debt covenants during 2018 will restrict the Company’s access to any additional cash draws from the revolving line of credit, and may require immediate repayment of the outstanding debt amounts. Management believes that it is probable that the Company will be able to either renew the revolving line of credit or obtain alternative financing on the acceptable terms. Various factors affect he 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^® solution 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. 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 line of credit with Silicon Valley Bank, assuming renewal of the line of credit 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 2018, 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 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, or SEC, and 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 statements of operations. 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. Actual results could differ from those estimates, particularly in relation to revenue recognition; the allowance for doubtful accounts; sales returns; valuation of investments; valuation of long-lived 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. 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. For the twelve months ended December 31, 2017, the Company generated 19% of its total revenue from shipments to a tier one customer, Samsung Electronics Co., Ltd. ("Samsung"). See Note 11 for information regarding revenue concentrations associated with our customers and distributors.
