Accounting Policies [Abstract]
Basis of Presentation and Updates to Accounting Policies	Basis of Presentation, and Updates to Accounting Policies Lattice Semiconductor Corporation, a Delaware corporation, and its subsidiaries (“Lattice,” the “Company,” “we,” “us,” or “our”) develop semiconductor technologies that we monetize through products, solutions, services, and licenses. Lattice was founded in 1983 and is headquartered in Hillsboro, Oregon. Basis of Presentation and Use of Estimates The accompanying Consolidated Financial Statements are unaudited and have been prepared in accordance with U.S. Generally Accepted Accounting Principles ("U.S. GAAP") and pursuant to the rules and regulations of the SEC. In our opinion, they include all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of results for the interim periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted by the SEC's rules and regulations for interim reporting. These Consolidated Financial Statements should be read in conjunction with our audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 29, 2018 ("2018 10-K"). The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and judgments affecting the amounts reported in our consolidated condensed financial statements and the accompanying notes. The actual results that we experience may differ materially from our estimates. We describe our accounting methods and practices in more detail in our 2018 10-K . Except for the impact of the adoption of the new lease accounting standard, discussed below, there have been no other changes to the significant accounting policies, procedures, or general information described in our 2018 10-K that have had a material impact on our consolidated financial statements and related notes. Updates to Accounting Policies On December 30, 2018, the first day of our 2019 fiscal year, we adopted Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842). See " Note 7 - Leases " for further information on our leases and our application of Topic 842. Fiscal Reporting Period We report based on a 52 or 53 week fiscal year ending on the Saturday closest to December 31. Our third quarter of fiscal 2019 and third quarter of fiscal 2018 ended on September 28, 2019 and September 29, 2018 , respectively. All references to quarterly or nine months ended financial results are references to the results for the relevant 13-week or 39-week fiscal period. Concentrations of Risk Distributors have historically accounted for a significant portion of our total revenue. Revenue attributable to distributors as a percentage of total revenue was 81% and 82% for the third quarter of fiscal 2019 and 2018, respectively, and 82% and 85% for the nine months ended September 28, 2019 and September 29, 2018 , respectively. In the periods covered by this report, no end customer accounted for more than 10% of total revenue. Distributors also account for a substantial portion of our net accounts receivable. At September 28, 2019 and December 29, 2018 , our largest distributor accounted for 43% and 41% , respectively, and our second largest accounted for 28% and 23% , respectively, of net accounts receivable. A third distributor accounted for 11% of net accounts receivable at September 28, 2019 , but accounted for less than 10% of net accounts receivable at December 29, 2018 . No other distributor or end customer accounted for more than 10% of net accounts receivable at these dates. Recently Issued Accounting Standards In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) , which clarifies the accounting for implementation costs in cloud computing arrangements. This guidance is effective for interim and annual reporting periods beginning after December 15, 2019, and early adoption is permitted. We are currently assessing the impact of ASU 2018-15 on our consolidated financial statements and related disclosures.

Earnings Per Share [Abstract]
Net Income (Loss) per Share	Net Income (Loss) per Share Our calculation of the diluted share count includes the number of shares from our equity awards with market conditions or performance conditions that would be issuable under the terms of such awards at the end of the reporting period. For equity awards with a market condition, the maximum number of shares issuable are included in the diluted share count as of September 28, 2019 , as the market condition would have been achieved at the highest level of vesting if measured as of the end of the reporting period. For equity awards with a performance condition, no shares are included in the diluted share count as of September 28, 2019 , as vesting of these awards is contingent upon evaluation of the performance condition over two consecutive trailing four-quarter periods starting as of the date the awards were issued, which have not yet elapsed. See " Note 9 - Stock-Based Compensation " to our consolidated financial statements for further discussion of our equity awards with market conditions or performance conditions. A summary of basic and diluted Net income (loss) per share is presented in the following table: Three Months Ended Nine Months Ended (in thousands, except per share data) September 28, September 29, September 28, September 29, Net income (loss) $ 13,539 $ 6,974 $ 29,506 $ (19,201 ) Shares used in basic Net income (loss) per share 132,997 127,816 132,065 125,578 Dilutive effect of stock options, RSUs, ESPP shares, and equity awards with a market condition or performance condition 5,897 1,658 5,614 — Shares used in diluted Net income (loss) per share 138,894 129,474 137,679 125,578 Basic Net income (loss) per share $ 0.10 $ 0.05 $ 0.22 $ (0.15 ) Diluted Net income (loss) per share $ 0.10 $ 0.05 $ 0.21 $ (0.15 ) The computation of diluted Net income (loss) per share excludes the effects of stock options, restricted stock units ("RSUs"), Employee Stock Purchase Plan ("ESPP") shares, and equity awards with a market condition or performance condition that are antidilutive, aggregating approximately the following number of shares: Three Months Ended Nine Months Ended (in thousands) September 28, September 29, September 28, September 29, Stock options, RSUs, ESPP shares, and equity awards with a market condition or performance condition excluded as they are antidilutive 909 2,299 328 8,284 Stock options, RSUs, and ESPP shares that are antidilutive at September 28, 2019 could become dilutive in the future.

Contract assets are included in Prepaid expenses and other current assets on our Consolidated Balance Sheets. The following table summarizes activity during the first nine months of fiscal 2019: (In thousands) Contract assets as of December 29, 2018 $ 9,143 Revenues recorded during the period 8,871 Transferred to Accounts receivable or collected (2,570 ) Contract assets as of September 28, 2019 $ 15,444 Contract liabilities are included in Accounts payable and accrued expenses on our Consolidated Balance Sheets. The following table summarizes activity during the first nine months of fiscal 2019: (In thousands) Contract liabilities as of December 29, 2018 $ 1,614 Accruals for estimated future stock rotation and scrap returns 4,397 Less: Release of accruals for recognized stock rotation and scrap returns (2,461 ) Prepayment for products to be manufactured and delivered to the customer within six months 751 Contract liabilities as of September 28, 2019 $ 4,301 The impact to revenue from the release of accruals for recognized stock rotation and scrap returns was offset by the processing of return merchandise authorizations totaling $2.8 million , yielding a net revenue reduction of $0.3 million for the first nine months of 2019. We will recognize the revenue related to the prepayment contract liability when control of the product is transferred to the end customer and the performance obligation has been satisfied.

Debt Disclosure [Abstract]
Long-Term Debt	Long-Term Debt On May 17, 2019, we entered into a new credit agreement (the “Current Credit Agreement”) with Wells Fargo Bank, National Association, as administrative agent, and other lenders. The Current Credit Agreement provides for a five -year secured term loan facility in an aggregate principal amount of $175.0 million and a five -year secured revolving loan facility in an aggregate principal amount of up to $75.0 million , along with other components and options, such as a letter of credit, swing line, or expansion of the revolver, currently not in use, which are more fully described in the Current Credit Agreement. We used the $175.0 million term loan proceeds and an initial $31.5 million revolving loan draw at closing to (i) repay the $204.4 million obligation outstanding under our previous credit agreement (the “Previous Credit Agreement”) with Jefferies Finance LLC, as administrative agent, and (ii) pay fees and expenses totaling $2.1 million incurred in connection with the Current Credit Agreement. The revolving loan may be used for working capital and general corporate purposes. With the repayment of our obligations under the Previous Credit Agreement, we wrote off the remaining unamortized balance of the related original issue discount and debt costs, which we recorded as a $2.2 million loss on refinancing in Other expense, net on our Consolidated Statements of Operations in the second quarter of fiscal 2019. At our option, the term loan and the revolving loan (collectively, "long-term debt") accrue interest at a per annum rate based on either (i) the base rate plus a margin ranging from 0.25% to 1.00% , determined based on our total leverage ratio or (ii) the London Interbank Offered Rate ("LIBOR") for interest periods of 1 , 2 , 3 or 6 months plus a margin ranging from 1.25% to 2.00% , determined based on our total leverage ratio. The base rate is defined as the highest of (i) the federal funds rate, plus 0.50% , (ii) Wells Fargo Bank, National Association’s prime rate or (iii) the LIBOR rate for a 1 -month interest period plus 1.00% . As of September 28, 2019, the effective interest rate on the term loan was 4.38% , and the revolving loan did not have an outstanding balance. We pay a commitment fee of 0.20% on the unused portion of the revolving loan. The term loan is payable through a combination of (i) required quarterly installments of approximately $4.4 million , and (ii) any payments due upon certain issuances of additional indebtedness and certain asset dispositions, with any remaining outstanding principal amount due and payable on the maturity date of the term loan. The revolving loan is payable at our discretion, with any remaining outstanding principal amount due and payable on the maturity date of the revolving loan. The Current Credit Agreement contains customary affirmative and negative covenants, including covenants limiting the ability of the Company to, among other things, incur debt, grant liens, undergo certain fundamental changes, make investments, make certain restricted payments, dispose of assets, enter into transactions with affiliates, and enter into burdensome agreements, in each case, subject to limitations and exceptions set forth in the Current Credit Agreement. We are also required to maintain compliance with a total leverage ratio and an interest coverage ratio, in each case, determined in accordance with the terms of the Current Credit Agreement. We account for the original issue discount and the debt issuance costs as a reduction to the carrying value of our long-term debt on our Consolidated Balance Sheets . We amortize the discount and costs to Interest expense in our Consolidated Statements of Operations over the contractual term using the effective interest method. We determine the Current portion of long-term debt as the sum of the required quarterly installments to be made over the next twelve months, reduced by the original issue discount and the debt issuance costs to be amortized over the next twelve months. The fair value of our long-term debt approximates the carrying value, which is reflected in our Consolidated Balance Sheets as follows: (In thousands) September 28, December 29, Principal amount $ 158,125 $ 263,033 Unamortized original issue discount and debt costs (1,699 ) (3,386 ) Less: Current portion of long-term debt (17,196 ) (8,290 ) Long-term debt, net of current portion and unamortized debt issue costs $ 139,230 $ 251,357 Interest expense related to our long-term debt was included in Interest expense on our Consolidated Statements of Operations as follows: Three Months Ended Nine Months Ended (In thousands) September 28, September 29, September 28, September 29, Contractual interest $ 1,686 $ 4,711 $ 8,991 $ 14,001 Amortization of debt issuance costs and discount 324 789 1,539 1,847 Total interest expense related to long-term debt $ 2,010 $ 5,500 $ 10,530 $ 15,848 Expected future principal payments are based on the schedule of required quarterly installments, adjusted for known voluntary payments.

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring In April 2019, our management approved and executed an internal restructuring plan (the “Q2 2019 Sales Plan”) which focused on a restructuring of the global sales organization through cancellation of certain contracts and a workforce reduction. Under this plan, we have incurred $2.3 million of restructuring expense during the first nine months of fiscal 2019. All actions planned under the Q2 2019 Sales Plan have been implemented. In June 2018, our Board of Directors approved an internal restructuring plan (the "June 2018 Plan"), which included the discontinuation of our millimeter wave business and the use of certain assets related to our Wireless products, and a workforce reduction. Under this plan, we incurred approximately $4.1 million of restructuring expense during the first nine months of fiscal 2018. This plan is substantially complete. In June 2017, our Board of Directors approved an internal restructuring plan (the "June 2017 Plan"), which included the sale of 100% of the equity of our Hyderabad, India subsidiary and the transfer of certain assets related to our Simplay Labs testing and certification business, a worldwide workforce reduction, and an initiative to reduce our infrastructure costs, including reconfiguring our use of certain leased properties. Under this initiative approved by the Board in 2017, we vacated 100% of our facility in Portland, Oregon in the first quarter of fiscal 2019. In the third quarter of fiscal 2019, we incurred approximately $0.3 million of incremental restructuring costs related to this vacated facility due to the timing of sublease transactions and to buyout the lease on the portion of the space that was not sublet. Under the June 2017 Plan, we incurred approximately $0.4 million and $0.1 million of expense during the third quarter of fiscal 2019 and fiscal 2018, respectively, and approximately $2.4 million and $1.4 million of expense during the nine months ended September 28, 2019 and September 29, 2018, respectively. We have incurred approximately $18.7 million of total expense through September 28, 2019 under the June 2017 Plan, and all planned actions have been implemented. We expect the total cost of the June 2017 Plan to be approximately $20.0 million to $21.5 million as expenses related to our partially vacated facility in San Jose, California will be incurred over the remaining lease term. These expenses were recorded to Restructuring charges on our Consolidated Statements of Operations. The restructuring accrual balance is presented in Accounts payable and accrued expenses and in Other long-term liabilities on our Consolidated Balance Sheets .

Leases

Leases [Abstract]
Leases	Leases We adopted ASC 842, " Leases ," effective on December 30, 2018, the first day of our 2019 fiscal year, using the modified retrospective transition method. The new standard requires lessees to record assets and liabilities on the balance sheet for all leases with terms longer than 12 months. We elected the "package of practical expedients" that would allow us to carryforward our historical lease classifications, not reassess historical contracts to determine if they contain leases, and not reassess the initial direct costs for any existing leases. We also elected the practical expedient to not separate lease and non-lease components. Concurrent with our adoption of Topic 842, we have early adopted ASU 2019-01, Leases (Topic 842): Codification Improvements, which grants disclosure relief for interim periods during the year in which a company adopted Topic 842. Right-of-use ("ROU") assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized on the commencement date of the lease based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available on the commencement date in determining the present value of lease payments. At inception, we determine if an arrangement is a lease, if it includes options to extend or terminate the lease, and if it is reasonably certain that we will exercise the options. Lease cost, representing lease payments over the term of the lease and any capitalizable direct costs less any incentives received, is recognized on a straight-line basis over the lease term as lease expense. We have operating leases for corporate offices, sales offices, research and development facilities, storage facilities, and a data center. Our leases have remaining lease terms of 1 to 8 years , some of which include options to extend for up to 5 years , and some of which include options to terminate within 1 year . The exercise of lease renewal options is at our sole discretion. When deemed reasonably certain of exercise, the renewal options are included in the determination of the lease term and lease payment obligation, respectively. For our leases that contain variable lease payments, residual value guarantees, or restrictive covenants, we have concluded that these inputs are not significant to the determination of the ROU asset and lease liability. For our operating leases, the weighted-average remaining lease term was 5.9 years and the weighted-average discount rate is 7.0% as of September 28, 2019. Our adoption of Topic 842 resulted in the non-cash recognition of additional net ROU assets and lease liabilities of approximately $29.9 million and $32.3 million , respectively, as of December 30, 2018. The difference between these amounts resulted from an adjustment to the deferred rent balance existing under the prior guidance. Adoption of this standard did not materially affect our consolidated net earnings. All of our facilities are leased under operating leases, which expire at various times through 2027. We recorded fixed operating lease expenses of $1.9 million and $5.8 million for the third quarter and first nine months of fiscal 2019, respectively. The following table presents the lease balance classifications within the Consolidated Balance Sheets and summarizes their activity during the first nine months of fiscal 2019: Operating lease right-of-use assets (in thousands) Balance as of December 29, 2018 $ — Right-of-use assets recorded from adoption of ASC 842 29,893 Right-of-use assets obtained in exchange for new lease obligations during the period 404 Amortization of right-of-use asset during the period (4,372 ) Impairment of right-of-use asset on Portland, Oregon office (recorded in Restructuring charges) (977 ) Adjustments for present value and foreign currency effects (385 ) Balance as of September 28, 2019 $ 24,563 Operating lease liabilities (in thousands) Balance as of December 29, 2018 $ — Lease liabilities recorded from adoption of ASC 842 32,273 Lease liabilities incurred for new lease obligations during the period 404 Accretion of lease liabilities 1,467 Operating cash used by payments on lease liabilities (6,540 ) Adjustments for present value, foreign currency, and restructuring liability effects (497 ) Balance as of September 28, 2019 27,107 Less: Current portion of operating lease liabilities (4,623 ) Long-term operating lease liabilities, net of current portion $ 22,484 Maturities of operating lease liabilities as of September 28, 2019 are as follows: Fiscal year (in thousands) 2019 (remaining 3 months) $ 1,051 2020 7,039 2021 5,294 2022 4,446 2023 4,574 Thereafter 11,388 Total lease payments 33,792 Less: amount representing interest (6,553 ) Less: amount representing restructuring liability adjustments (132 ) Total lease liabilities $ 27,107 Prior to 2019, the reporting of future minimum lease commitments included the lease obligations associated with previously restructured facilities.

During the second quarter of fiscal 2018 , in addition to recurring amortization expense, we recorded an impairment charge relating to intangible assets of $11.9 million in the Consolidated Statements of Operations as a result of the strategic decision to discontinue our millimeter wave business.

During the third quarter of fiscal 2019, we granted approximately 0.3 million additional awards of RSUs with a market condition to certain executives. Under the terms of these grants, vesting of the market condition RSUs will not occur unless the Company achieves total shareholder return at least equivalent to the 25 th percentile of semiconductors on the Philadelphia Stock Exchange, which condition is tested for one-third of the grants on the first, second and third anniversary of grants. If the 75 th percentile of the market condition is achieved the awards may vest at 250% or 200% for the executives. Also during the third quarter of fiscal 2019, the market condition for awards granted in the previous year achieved the 75 th percentile of the condition, and the first tranche of these awards vested at 250% or 200% of the RSUs, as applicable for the respective executive. For these awards, we incurred stock compensation expense of approximately $0.9 million and $0.1 million in the third quarter of fiscal 2019 and fiscal 2018 , respectively, and approximately $2.9 million and $0.6 million in the first nine months of fiscal 2019 and fiscal 2018 , respectively, which is recorded as a component of total stock-based compensation expense.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We are subject to federal and state income tax as well as income tax in the foreign jurisdictions in which we operate. For the third quarter of fiscal 2019 and fiscal 2018, we recorded income tax expense of approximately $1.1 million and $0.1 million , respectively, and for the first nine months of fiscal 2019 and fiscal 2018, we recorded income tax expense of approximately $1.5 million and $2.0 million , respectively. Income taxes for the three and nine month periods ended September 28, 2019 and September 29, 2018 represent tax at the federal, state, and foreign statutory tax rates adjusted for withholding taxes, changes in uncertain tax positions, changes in the U.S. valuation allowance, as well as other non-deductible items in the United States and foreign jurisdictions. The difference between the U.S. federal statutory tax rate of 21% and our effective tax rate for the three and nine months ended September 28, 2019 resulted primarily from a decrease in the valuation allowance that offset expected tax expense in the United States, foreign withholding tax expense, discrete impact from uncertain tax positions, and foreign rate differential primarily due to zero tax rate in Bermuda. For the three and nine months ended September 29, 2018, the difference resulted from an increase in the valuation allowance that offset expected tax benefit in the United States, foreign rate differential and withholding taxes, zero tax rate in Bermuda which resulted in no tax benefit for the pretax loss in Bermuda, and a benefit from the release of uncertain tax positions. Through September 28, 2019 , we continued to evaluate the valuation allowance position in the United States and concluded that we should maintain a full valuation allowance against the net federal and state deferred tax assets. In making this evaluation, we exercised significant judgment and considered estimates about our ability to generate revenue and taxable profits sufficient to offset expenditures in future periods within the U.S. It is reasonably possible that during the next nine to twelve months, we will establish a sustained level of profitability in the U.S. As a result, we may reverse a significant portion of the valuation allowance recorded against our U.S. deferred tax assets. The reversal would result in an income tax benefit for the quarterly and annual fiscal period in which we release the valuation allowance. We will continue to evaluate both positive and negative evidence in future periods to determine if we should recognize more deferred tax assets. We do not have a valuation allowance in any foreign jurisdictions as we have concluded it is more likely than not we will realize the net deferred tax assets in future periods. At September 28, 2019 , it is reasonably possible that $1.3 million of unrecognized tax benefits and $0.2 million of associated interest and penalties could be recognized during the next twelve months. The $1.5 million potential change would represent a decrease in unrecognized tax benefits, comprised of items related to tax filings for years that will no longer be subject to examination under expiring statutes of limitations. Our liability for uncertain tax positions (including penalties and interest) was $25.9 million and $26.3 million at September 28, 2019 and December 29, 2018 , respectively, and is recorded as a component of Other long-term liabilities on our Consolidated Balance Sheets . The remainder of our uncertain tax position exposure of $24.5 million is netted against deferred tax assets. We are not currently paying U.S. federal income taxes and do not expect to pay such taxes until we fully utilize our tax net operating loss ("NOL") and credit carryforwards. We expect to pay a nominal amount of state income tax. We are paying foreign income and withholding taxes, which are reflected in Income tax expense in our Consolidated Statements of Operations and are primarily related to the cost of operating offshore activities and subsidiaries. We accrue interest and penalties related to uncertain tax positions in Income tax expense.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Legal Matters On or about December 19, 2018, Steven A.W. De Jaray, Perienne De Jaray and Darrell R. Oswald (collectively, the “Plaintiffs”) commenced an action against the Company and several unnamed defendants in the Multnomah County Circuit Court of the State of Oregon, in connection with the sale of certain products by the Company to the Plaintiffs in or around 2008. The Plaintiffs allege that we violated The Lanham Act, engaged in negligence and fraud by failing to disclose to the Plaintiffs the export-controlled status of the subject parts. The Plaintiffs seek damages of $138 million , treble damages, and other remedies. In January 2019, we removed the action to the United States District Court for the District of Oregon. At this stage of the proceedings, we do not have an estimate of the likelihood or the amount of any potential exposure to the Company; however, we believe that these claims are without merit and intend to vigorously defend the action. From time to time, we are exposed to certain asserted and unasserted potential claims. Periodically, we review the status of each significant matter and assess its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and a range of possible losses can be estimated, we then accrue a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based only on the best information available at the time. As additional information becomes available, we reassess the potential liability related to pending claims and litigation and may revise estimates.

In our opinion, they include all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of results for the interim periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted by the SEC's rules and regulations for interim reporting. These Consolidated Financial Statements should be read in conjunction with our audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 29, 2018 ("2018 10-K").
Use of Estimates	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and judgments affecting the amounts reported in our consolidated condensed financial statements and the accompanying notes. The actual results that we experience may differ materially from our estimates.
Fiscal Reporting Period	Fiscal Reporting Period We report based on a 52 or 53 week fiscal year ending on the Saturday closest to December 31.
