Organization, Consolidation and Presentation of Financial Statements [Abstract]
Fiscal period	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 second fiscal quarters for 2017 and for 2016 ended on Sunday, July 2, 2017 and July 3, 2016, respectively.
Liquidity	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 July 2, 2017, the Company's principal sources of liquidity consisted of cash and cash equivalents of $22.2 million and $6.0 million in credit available at the Company's election under its revolving line of credit with Silicon Valley Bank, which expires on September 25, 2017. The Company has drawn down all of the $6.0 million in currently available credit under its revolving line of credit. On September 25, 2015, the Company entered into a Second Amendment to the Third Amended and Restated Loan and Security Agreement with Silicon Valley Bank to extend the line of credit for two years through September 25, 2017. This amendment modifies some of the financial covenants. This line of credit provides for committed loan advances of up to $6.0 million, subject to increases at the Company's election of up to $12.0 million. On February 10, 2016, the Company entered into a Third Amendment to the Third Amended and Restated Loan and Security Agreement to further modify the covenants. See Note 5 for a description of the modified covenants. The Company is in compliance with all loan covenants as of the end of the current reporting period. 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 $15.8 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 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 operations. Based on past operating performance and current annual operating plans, 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 from the date the condensed unaudited consolidated financial statements as of and for the three and six-month periods ended July 2, 2017 are available to be issued. 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 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 the generation of sales 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 this existing revolving line of credit in September 2017, 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	Principles of Consolidation The consolidated financial statements include the accounts of QuickLogic and its whollyowned subsidiaries. All intercompany accounts and transactions have been eliminated.
Foreign Currency	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 condensed unaudited consolidated statements of operations.
Uses of Estimates	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.
Concentration of Risk	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.
New Accounting Pronouncements	New Accounting Pronouncements Recently adopted accounting pronouncements: In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the measurement of Inventory, which amends the accounting guidance on the valuation of inventory. The guidance requires an entity to measure in scope inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The amendment applies to inventory valued at first-in, first-out or average cost. This guidance is effective for reporting periods beginning after December 15, 2016, including interim periods within those fiscal years. The Company adopted this guidance in the first quarter of 2017 prospectively with no material effect on the consolidated financial statements. Recently issued accounting pronouncements not yet adopted: In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. In July 2015, the FASB approved a one-year delay in the effective date by issuing ASU 2015-09, Revenue from Contracts with customers. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The Company is currently evaluating the impact of the adoption of ASU 2014-09 on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases. The new standard establishes a right-of-use ("ROU") model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact of our pending adoption of the new standard on the consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-08, Revenue from contracts with customers (Topic 606): Principal versus Agent Considerations Reporting Revenue Gross versus Net. The amendments are intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations by amending certain existing illustrative examples and adding additional illustrative examples to assist in the application of the guidance. The effective date and transition of these amendments is the same as the effective date and transition of ASU 2014-09. Public entities should apply the amendments in ASU 2014-09 for annual reporting periods beginning after December 15, 2017, including interim reporting periods therein (i.e., January 1, 2018, for a calendar year entity). Private entities must apply the amendments one year later. The Company is currently evaluating the impact of our pending adoption of the new standard on the consolidated financial statements. In May 2016, the FASB issued ASU No. 2016-12, Revenue from contracts with customers (Topic 606): Narrow Scope Improvements and Practical Expedients. The amendments among other things: (1) clarify the object of the collectability criterion for applying paragraph 606-10-25-7; (2) permit an entity to exclude amounts collected from customers for all sales (and other similar) taxes from transaction price; (3) specify that the measurement date for noncash consideration is contract inception; (4) provide a practical expedient that permits an entity to reflect the aggregate effect of all modifications that occur before the beginning of the earliest period presented when identifying the satisfied and unsatisfied performance obligations, determining the transaction price, and allocating the transaction price to the satisfied and unsatisfied performance obligations; (5) clarify that a completed contract for purposes of transition is a contract for which all (or substantially all) of the revenue was recognized under legacy GAAP before the date of initial application, and (6) clarify that an entity that retrospectively applies the guidance in Topic 606 to each prior period reporting is not required to disclose the effect of the accounting change for the period of adoption. This amendment is effective for public entities for annual reports beginning after December 15, 2017, including interim periods therein. The Company is currently evaluating the impact of our pending adoption of the new standard on the consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This update clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This ASU is effective for public business entities for fiscal years beginning after December 15, 2017, and for interim periods therein with early adoption permitted and must be applied retrospectively to all periods presented. The Company is currently evaluating the impact of our pending adoption of the new standard on the consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity transfers of assets other than inventory. This update removes the requirement under which the income tax consequences of intra-entity transfers are deferred until the assets are ultimately sold to an outside party, except for transfers of inventory. The tax consequences of such transfers would be recognized in tax expense when the transfers occur. The standard is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those annual periods. Early adoption is permitted. The Company is currently evaluating the impact of adopting this guidance on the consolidated financial statements. In May 2017, the FASB issued ASU No. 2017-09, Compensation-Stock Compensation (Topic 718). ASU No. 2017-09 provides clarification on when modification accounting should be used for changes to the terms or conditions of a share-based payment award. This ASU does not change the accounting for modifications but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions or award classification and would not be required if the changes are considered non-substantive. The amendments of this ASU are effective for reporting periods beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the impact of adopting this guidance on the consolidated financial statements. Other new accounting pronouncements are disclosed on the Annual Report on Form 10-K for the fiscal year ended January 1, 2017 filed with the SEC on March 9, 2017.
Net Loss per Share	Basic loss per share is computed by dividing net loss available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net loss per share was computed using the weighted average number of common shares outstanding during the period plus potentially dilutive common shares outstanding during the period under the treasury stock method. In computing diluted net loss per share, the weighted average stock price for the period is used in determining the number of shares assumed to be purchased from the exercise of stock options and warrants.
Revenue Recognition	The Company accounts for its IP license revenues and related services in accordance with Financial Accounting Standard Board or FASB Accounting Standards Codification or ASC No. 985-605, Software Revenue Recognition. Revenues are recognized when persuasive evidence of an arrangement exists and no further obligation exists, delivery has occurred, the license fee is fixed or determinable, and collection is reasonably assured. A license may be perpetual or time limited in its application. The Company’s IP license agreement contains multiple elements including post-contract customer support. For multiple element arrangements involving software and other software-related deliverables, vendor-specific objective evidence of fair value (“VSOE”) must exist to allocate the total fee among all delivered and non-essential undelivered elements of the arrangement. If undelivered elements of the arrangement are essential to the functionality of the product, revenue is deferred until the essential elements are delivered. If VSOE does not exist for one or more non-essential undelivered elements, revenue is deferred until such evidence exists for the undelivered elements, or until all elements are delivered, whichever is earlier. VSOE of each element is based on historical evidence of stand-alone sales of these elements to third parties including substantive renewal rate as stated in the agreement. When VSOE does not exist for undelivered items, the entire arrangement fee is recognized ratably over the performance period. As the IP license agreement entered into during the quarter ended April 2, 2017 is the first such revenue agreement, no VSOE exists for any of the elements. Accordingly, the Company is recognizing revenue associated with this contract ratably over the performance period.
