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", 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 2018, 2017 and 2016 ended on December 30, 2018, December 31, 2017 and January 1, 2017, respectively. Liquidity The Company has financed its operations and capital investments through sale of common stock, capital and operating leases, a revolving line of credit and cash flows from operations. As of December 30, 2018, the Company’s principal sources of liquidity consisted of cash and cash equivalents of $26.5 million and $15.0 million line of credit with Heritage Bank of Commerce (“Heritage Bank”). The Line of credit facility with Silicon Valley Bank, which matured on September 24, 2018 was fully paid off in July 2018. 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 line of credit facility (the “Revolving Facility”) with aggregate commitments of $9,000,000 . The maturity date for loans under the Revolving Facility is September 28, 2020. 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. On December 21, 2018, the Company entered into the Amended and Restated Loan Agreement with Heritage Bank to replace in its entirety the Loan Agreement entered on September 28, 2018. The Amended and Restated Loan Agreement increases the Revolving Facility from $9,000,000 to $15,000,000. Further, the Amended and Restated Loan Agreement eliminates the requirement of maintaining at all times Remaining Months Liquidity of nine months and replaces with a new covenant of maintaining at least $3,000,000 in unrestricted cash at Heritage Bank. The Company was in compliance with all loan covenants as of the end of the current reporting period. As of December 30, 2018, the Company had $15.0 million of outstanding revolving line of credit with an interest rate of 6%. In May 2018, the Company issued an aggregate of 13,513,510 shares of common stock, $0.001 par value and warrants to purchase up to an aggregate of 5,405,404 shares of common stock in an underwritten public offering. The common stock and warrants were issued in units (the “Units”), with each Unit consisting of (i) one share of common stock and (ii) a warrant to purchase 0.40 of a share of common stock, at a combined price of $1.15 per Unit. We received total net proceeds from the offering of $13.9 million, net of underwriting discounts and other offering expenses of $1.6 million. 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. See Note 8 to the Consolidated Financial Statements for more details. The common stock 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. The estimated grant date fair value of the common stock warrants was $0.57 per warrant and was calculated based on the following assumptions used in the Black-Scholes model: expected term of 5 years, risk-free interest rate of 2.58%, expected volatility of 52.75% and expected dividend of zero. In March 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 used the net proceeds for working capital, to accelerate the development of next generation products and for general corporate purpose. 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 Facility with Heritage 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 Facility with Heritage Bank will expire in September 2020 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 2019 will restrict the Company’s access to any additional cash draws from the Revolving Facility, 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 Facility or obtain alternative financing on the acceptable terms. 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^® 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 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 September 2020, 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. See Exhibit 21 for the listing of 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; determination of the Stand Alone Selling Price, or SSP, for each distinct performance obligation; 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 and revenue.
