Basis Of Presentation [Abstract]
Basis Of Presentation	 Note 1 — Basis of Presentation  Intersil Corporation (“Intersil,” which may also be referred to as “we,” “us,” or “our”) is a leading provider of innovative power management and precision analog semiconductor solutions. Our products address some of the largest markets within the industrial and infrastructure, and consumer and computing end markets.  In our opinion, these unaudited condensed consolidated financial statements include all adjustments necessary to present fairly, in all material respects, the financial position, results of operations, and cash flows for all periods presented. We prepared these unaudited condensed consolidated financial statements in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X, using management estimates where necessary. We derived the January 1, 2016 condensed consolidated balance sheet from our audited consolidated year-end financial statements. You should read this interim report in conjunction with our Annual Report on Form 10-K for the year ended January 1, 2016 .  We utilize a 52/53 fiscal week year, ending on the nearest Friday to December 31. Fiscal years 2016 and 2015, are and were, respectively, 52-week years. Quarterly and annual periods vary from exact calendar quarters and years.  Pending Merger with Renesas Electronics Corporation  On September 12, 2016 , we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Renesas Electronics Corporation, a Japanese corporation (“Renesas”). The Merger Agreement provides that, upon the terms and subject to the satisfaction or valid waiver of the conditions set forth in the Merger Agreement, a wholly owned subsidiary of Renesas will merge with and into Intersil (the “Merger”), with Intersil continuing as the surviving corporation and a direct wholly owned subsidiary of Renesas. At the effective time of the Merger, each outstanding share of Class A common stock, par value $ 0.01 per share , of Intersil (“Class A common stock” or “common stock”) , other than shares held by stockholders who have validly exercised their appraisal rights under Delaware law, and certain shares owned by Intersil, Renesas and their subsidiaries, will be automatically converted into the right to receive $ 22.50 in cash, without interest and less any applicable withholding taxes, plus, if applicable, the amount of any dividend which has a record date prior to the closing date of the Merger but remains unpaid as of the closing date of the Merger.  The consummation of the merger is conditioned on the receipt of the approval of our stockholders, as well as the satisfaction of other customary closing conditions, including domestic and foreign regulatory approvals and performance in all material respects by each party of its obligations under the Merger Agreement. Consummation of the Merger is not subject to a financing condition. Closing of the merger is expected in the first half of 2017.  The Merger Agreement contains certain termination rights for us and Renesas, including if a governmental body prohibits the Merger or if the Merger is not consummated before July 12, 2017. Upon termination of the Merger Agreement under specified circumstances, we or Rene sas will be required to pay the other party a termination fee of $ 96.5 million.  We recorded transaction-related costs of $ 4.6 million, principally for outside financial advisory, legal, and related fees and expenses associated with the pending acquisition , in the quarter ended September 30, 2016. Additional transaction-related costs are expected to be incurred through the closing of the Merger .  Recent Accounting Guidance Not Yet Adopted In January 2016, the Financial Accounting Standards Board, or FASB, issued Accounting Standard update, or ASU, 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities , which provides guidance for the recognition, measurement, presentation, and disclosure of financial assets and liabilities. This ASU will be effective for us beginning in the first quarter of 2018. We are currently evaluating the impact of the adoption of this ASU on our financial statements. In February 2016, FASB issued ASU 2016-02, Leases (Topic 842), which supersedes existing guidance on accounting for leases in “Leases (Topic 840)” and generally requires all leases to be recognized in the consolidated balance sheet. ASU 2016-02 is effective for annual and interim reporting periods beginning after December 15, 2018; early adoption is permitted. The provisions of ASU 2016-02 are to be applied using a modified retrospective approach. We are currently evaluating the impact of the adoption of this guidance on our consolidated financial statements. In March 2016, FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting . This ASU affects entities that issue equity-based payment awards to their employees. The ASU is designed to simplify several aspects of accounting for equity-based payment award transactions, which include income tax consequences, classification of awards as either equity or liabilities, classification on the statement of cash flows, and forfeiture rate calculations. ASU 2016-09 will become effective for us beginning in the first quarter of 2017; early adoption is permitted. We are currently evaluating the impact of the adoption of this guidance on our consolidated financial statements. In April 2016, FASB issued an update to ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. The amendments in this update clarify the following two aspects of Topic 606: identifying performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. We are currently evaluating the impact of the adoption of this guidance on our consolidated financial statements.

Significant Accounting Policies [Abstract]
Significant Accounting Policies	Note 2 — Significant Accounting Policies The accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year ending December 30, 2016. There have been no changes to our significant accounting policies described in our Annual Report on Form 10-K for the year ended January 1, 2016 that have had a material impact on our unaudited condensed consolidated financial statements and related notes.

Fair Value Measurements [Abstract]
Fair Value Measurements	 Note 3 — Fair Value Measurements We determine the fair value of our assets and liabilities utilizing three levels of inputs, focusing on the most observable level of inputs when available. Level 1 inputs use quoted prices in active markets which are unadjusted and accessible as of the measurement date for identical, unrestricted assets or liabilities. Level 2 uses quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly. Level 3 uses prices or valuations that require inputs that are unobservable and significant to the overall fair value measurement. We determine fair value on the following assets using these input levels (in thousands):     Fair value as of September 30, 2016 using:  Total Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2)  Assets  Other non-current assets:  Deferred compensation investments $ 9,917 $ 87 $ 9,830  Total assets measured at fair value $ 9,917 $ 87 $ 9,830   Fair value as of January 1, 2016 using:  Total Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2)  Assets  Other non-current assets:  Deferred compensation investments $ 9,855 $ 400 $ 9,455  Total assets measured at fair value $ 9,855 $ 400 $ 9,455  There were no transfers into or out of Level 1, Level 2, or Level 3 financial assets during the three quarters ended September 30, 2016 and October 2, 2015.

Goodwill And Purchased Intangibles [Abstract]
Goodwill And Purchased Intangibles	Note 5 — Goodwill and Purchased Intangibles  Goodwill — We perform our annual test of impairment in our fourth quarter, or if indicators of impairment exist, in interim periods. Factors that could trigger a goodwill impairment review include adverse legal factors, adverse changes in our business climate, unanticipated competition, regulatory issues, loss of key personnel, significant changes or losses in business operations, weakness in our industry, downward revisions to forecasts for future periods, restructuring plans, and declines in market capitalization below equity book value.  There were no impairment triggers noted during the three quarters ended September 30, 2016.  Purchased Intangibles — Our intangible assets consisted of the following (in thousands):     As of September 30, 2016  Definite-lived: developed technologies Definite-lived: other Total purchased intangibles   Gross carrying amount $ 63,032 $ 14,600 $ 77,632  Accumulated amortization 42,151 12,038 54,189  Purchased intangibles, net $ 20,881 $ 2,562 $ 23,443   As of January 1, 2016  Definite-lived: developed technologies Definite-lived: other Total purchased intangibles   Gross carrying amount $ 63,032 $ 46,700 $ 109,732  Accumulated amortization 36,065 41,160 77,225  Purchased intangibles, net $ 26,967 $ 5,540 $ 32,507  Substantially all of our purchased intangibles consist of multiple elements of developed technology which have estimated useful lives of five to seven years. Other purchased intangibles consist primarily of customer relationships and other identifiable assets, which have an estimated useful life of three to seven years. No trigger requiring an impairment review was noted during the three quarters ended September 30, 2016.  Expected remaining amortization expense by year to the end of the current amortization schedule is as follows (in thousands):      To be recognized in:  2016 $ 2,670  2017 9,480  2018 4,362  2019 1,890  2020 and thereafter 5,041  Total expected amortization expense $ 23,443

Income Taxes [Abstract]
Income Taxes	Note 6 — Income Taxes  Our income tax expense was $7.0 million, which equates to an effective tax rate of 30.7% , for the quarter ended September 30, 2016 compared to an income tax expense of $0.3 million, which equated to an effective tax rate of 1.7% , for the quarter ended October 2, 2015. Our income tax expense was $10.8 million, which equates to an effective tax rate of 27.1% , for the three quarters ended September 30, 2016 compared to an income tax benefit of $16.3 million, which equated to a negative effective tax rate of 53.6% , for the three quarters ended October 2, 2015.  Our effective tax rate for the quarter ended September 30, 2016 differs from the 35% U.S. federal statutory income tax rate due primarily to income earned in jurisdictions where the tax rate is lower than the United States, principally in Malaysia, state income taxes, U.S. research and development tax credits, U.S. domestic production activity and other permanent non-deductible items. Our effective tax rate was negative for the quarter ended October 2, 2015, primarily due to losses in foreign jurisdictions related to the TAOS litigation. The $ 81.1 million accrual recorded for the TAOS litigation was treated as an unusual and discrete item for the quarter, for which the future tax benefit was $ 1.2 million, and the loss was allocated primarily to our Malaysian operations. Additionally, the three quarters ended October 2, 2015 included a net tax benefit of $ 27.7 million related to the release of a reserve for an uncertain tax position for which the statutes of limitation in certain jurisdictions expired during the period.  As of September 30, 2016, we have no material changes resulting from examination s in major tax jurisdictions. Accordingly, we have no material changes to our unrecognized tax benefits and related interest and penalty since the year ended January 1, 2016. We do not believe that there will be a significant increase or decrease in unrecognized tax benefits within the next twelve months.

Long Term Debt [Abstract]
Long-Term Debt	Note 7 — Long-Term Debt  On July 19, 2016, we entered into an amended and restated five -year, $ 225.0 million revolving credit facility, or the Amended Facility, that matures on July 19, 2021 and is payable in full upon maturity. The Amended Facility replaces our five -year, $ 325.0 million revolving credit facility, or the Facility, that would have matured on September 1, 2016 . Under the Amended Facility, $50.0 million is available for the issuance of standby letters of credit, $ 30.0 million is available as swing line loans, and $ 70.0 million is available for multicurrency borrowings. Amounts repaid under the Amended Facility may be re-borrowed. We did not have any outstanding borrowings against the Amended Facility as of September 30, 2016 or against the Facility as of January 1, 2016.  Standby Letters of Credit — We issue standby letters of credit during the ordinary course of business through major financial institutions as required for certain regulatory matters. We had outstanding letters of credit to taling $1.1 million and $1.3 million as of September 30, 2016 and January 1, 2016, respectively. The standby letters of credit are secured by pledged deposits.

Legal Matters And Indemnifications [Abstract]
Legal Matters And Indemnifications	Note 12 — Legal Matters and Indemnifications  Other than as stated in this Note 12, there were no material changes in our legal matters and indemnifications, from those disclosed in our Annual Report on Form 10-K for the year ended January 1, 2016.  TAOS litigation Texas Advanced Optoelectronic Solutions, Inc., or TAOS, named us as a defendant in a lawsuit filed on November 25, 2008 in the United States District Court for the Eastern District of Texas. In this action, TAOS alleged four claims consisting of patent infringement, breach of contract, trade secret misappropriation, and tortious interference with a business relationship. On March 6, 2015, the jury found in favor of TAOS on each of the four claims. After certain post-trial motions were heard, the court entered a final judgment on June 9, 2016 against us in the amount of $ 77.3 million plus court costs and a continuing royalty on certain products found to be infringing TAOS’ patent. On June 10, 2016, we filed a notice of appeal; TAOS filed a notice of cross-appeal. Our opening brief is due to be filed on October 28, 2016. As a consequence of the jury’s verdict, during the quarter ended April 3, 2015, we recorded a provision of $ 81.1 million related to this matter, including pre-judgment interest and estimated legal costs. As a result of the entry of the June 9, 2016 judgment, we increased our accrual for this matter by $ 1. 3 million in the quarter ended July 1, 2016 . Given the unpredictable nature of this type of litigation and because the outcome remains subject to appeal, the ultimate impact of this lawsuit may be materially different from our estimate. Environmental matter  In correspondence dated September 28, 2015, counsel for Thomson Consumer Electronics Television Taiwan, Ltd., or TCETVT, notified us that it reserved its right to seek indemnification from us for any and all costs, fees, and expenses incurred as a result of a toxic tort class action lawsuit filed in Taiwan against TCETVT and others. The lawsuit pertains to alleged injuries resulting from groundwater contamination at a manufacturing facility in Taiwan currently owned by TCETVT, which was previously owned and operated by predecessors, including General Electric, or GE, and Harris Corporation, or Harris, of our Taiwan subsidiary, Intersil Ltd. In the September 28 correspondence, TCETVT also informed us that the Taipei District Court entered a judgment of $ 18.5 million in the lawsuit against TCETVT, which judgment has been appealed. In addition, TCETVT informed us that they have incurred costs of $ 11.2 million in defending against the lawsuit through September 1, 2015. We were also advised by TCETVT that additional claimants made be added to the lawsuit and TCETVT believes that if such additional claimants were successfully added, the resulting liability could be as high as $ 200.0 million. In its September 28, 2015 letter, TCETVT informed us that it reserved its right to seek indemnification from us for any and all costs associated with the remediation of the contamination on that site and nearby areas. TCETVT claims they have incurred $ 15.9 million in remediation-related costs through September 1, 2015.  By letter dated June 22 , 2016 from counsel for GE and by letter dated July 14, 2016 from counsel for TCETVT, we were advised that in April 2016 the Taiwan Supreme Court denied the request to add additional claimants to the existing lawsuit and that, in response to the denial, the plaintiffs filed a new, but related lawsuit, claiming damages on behalf of 1,147 new claimants as well as adding additional sites at which the toxic torts were alleged to have occurred , such that the resulting liability could be as high as an additional $ 225.0 million. Under the terms of the 1999 Master Transaction Agreement between Harris and Intersil, whereby Harris transferred its semiconductor business assets to us, environmental liabilities (including those associated with Harris’ Taiwan semiconductor operations) were expressly retained by Harris. The Master Transaction Agreement also requires Harris to indemnify us for any and all costs relating to those retained environmental liabilities. We have denied liability to TCETVT for the costs associated with the lawsuit as well as the costs associated with the remediation of the contamination on the site. We have also submitted a claim notice to Harris seeking defense and indemnification from Harris under the Master Transaction Agreement for any and all claims made by TCETVT in connection with this matter. Harris has not yet agreed to indemnify us for the liability asserted by TCETVT.  Export Compliance Settlement  A portion of our activities are subject to export control regulations administered by the U.S. Department of State, or DOS, under the U.S. Arms Export Control Act, or AECA, and the International Traffic in Arms Regulations, or ITAR. In September 2010, in response to a request for information, we disclosed to the Directorate of Defense Trade Controls, or DTCC, information concerning export activities for the years of 2005 through 2010. ITAR gives the DOS authority to impose civil penalties and other administrative sanctions for violations, including debarment from engaging in the exporting of defense articles. In June of 2013, the DTCC notified us of potential ITAR violations and that it was considering pursuing administrative proceedings against us. On June 16, 2014, we entered into a Consent Agreement with the DTCC for the purpose of resolving the potential ITAR violations. The Consent Agreement contained a two -year term and provided for: (i) payment of an aggregate civil penalty of $ 10.0 million, $ 4.0 million of which was suspended and eligible for an offset credit based on verified expenditures for certain past and future remedial compliance measures; (ii) the appointment of an Internal Special Compliance Official to oversee compliance with the Consent Agreement and U.S. export control regulations, in general; (iii) two external audits of our ITAR compliance program; and (iv) continued implementation of ongoing remedial compliance measures and additional remedial compliance measures related to automated systems and ITAR compliance policies, procedures, and training. In connection with the Consent Agreement, we estimated and recorded a $ 6.0 million charge in the quarter ended October 4, 2013 and an additional $4.0 million charge in the quarter ended April 4, 2014, when the amount of the penalty was determined. The $ 6.0 million portion of the settlement, which was not subject to suspension, was paid in two installments of $ 3.0 million each , in June 2014 and June 2015. On March 29, 2016, we notified the DTCC that we had met all of the requirements under the Consent Agreement, as required by Paragraph 30 of the Consent Agreement. On June 17, 2016, we notified the DTCC that the investments we had made in our export control compliance program, which included additional staffing, ongoing implementation of a new software system, employee training, and establishment of a regular compliance audit program and corrective action process, were eligible for credit against the entire amount of the suspended portion of the settlement amount. On June 20, 2016, the DTCC notified us that the expenses we incurred were eligible for and credited against the entire $4.0 million suspended payment. Finally, on June 21, 2016, the DTCC notified us that it had closed the Consent Agreement based, in part, on DTCC’s conclusion that we had fulfilled the terms of the Consent Agreement.  We are currently party to various claims and legal proceedings, including those discussed above. When we believe that a loss is probable and the amount of the loss can be reasonably estimated, we recognize the estimated amount of the loss. We include legal costs in the estimate of losses. As additional information becomes available, we reassess any potential liability related to these matters and, if necessary, revise the estimates. We do not believe, based on currently available facts and circumstances that the ultimate outcome of these matters, individually and in the aggregate, will have a material adverse effect on our financial position or overall trends in results of our operations in excess of amounts already accrued. However, litigation is subject to inherent uncertainties and unfavorable rulings could occur, including an award of substantial monetary damages or issuance of an injunction prohibiting us from selling one or more products. From time-to-time, we may enter into confidential discussions regarding the potential settlement of such lawsuits. Any settlement of pending litigation could require us to incur substantial costs and other ongoing expenses, such as future royalty payments in the case of an intellectual property dispute. There can be no assurances that the actual amounts required to satisfy any liabilities arising from the matters described above will not have a material adverse effect on our results of operations, financial position, or cash flows.  We incur indemnification obligations for intellectual property infringement claims related to our products. We accrue for known indemnification issues and estimate unidentified issues based on historical activity.

Assets Held For Sale And Restructuring And Related Costs [Abstract]
Assets Held For Sale And Restructuring And Related Costs	Note 13 — Assets held for sale and Restructuring and Related Costs  On June 29, 2016, we began implementation of a plan to decommission our 200 millimeter wafer fabrication line in Palm Bay, Florida or the 200mm Line. The investment in the 200mm Line was made approximately four years ago to address the need to extend the production life of certain products manufactured at a third party wafer foundry when the supply commitments from the supplier for these products were set to expire at the end of 2014. In July 2015, the supplier was acquired and the acquirer recently decided to continue long-term support for the manufacturing of these products. To avoid the future capital investment anticipated to be required for the 200mm Line, we determined it would be beneficial to our long-term cost structure to source the manufacturing for these products from this supplier and decommission our 200mm Line. Due to this shift in manufacturing to an outside provider, we recorded an impairment charge of $ 9.9 million during the quarter ended July 1, 2016 on these long-lived assets related to the 200mm Line. The impairment charge was calculated as the excess of the assets’ carrying value over their fair value as determined by the market prices of these types of assets. We also recorded impairment charges of $ 1 million during the quarter ended July 1, 2016 for specific inventory items related to the 200 mm Line which had no alternative use. In addition we recorded $ 2.5 million of severance and other employee benefit costs in the quarter ended July 1, 2016 related to the decommissioning and other cost reduction actions.  During the quarter ended September 30, 2016, long lived assets (comprising of property, plant and equipment with a net book value of $ 4.9 million) relating to the 200 mm Line have been classified as assets held for sale. We measure long-lived assets to be disposed of by sale at the lower of carrying amount or fair value less cost to sell. Fair value is determined using quoted market prices or the anticipated cash flows discounted at a rate commensurate with the risk involved. No additional gain or loss was recorded since these assets were reduced to their fair value during the quarter ended July 1, 2016. We have entered into an agreement for sale of these assets and received an advance of $ 2.5 million. We expect to complete the sale within next twelve months.

Basis Of Presentation [Abstract]
Fiscal Period	We utilize a 52/53 fiscal week year, ending on the nearest Friday to December 31. Fiscal years 2016 and 2015, are and were, respectively, 52-week years. Quarterly and annual periods vary from exact calendar quarters and years.
Recent Accounting Guidance Not Yet Adopted	Recent Accounting Guidance Not Yet Adopted In January 2016, the Financial Accounting Standards Board, or FASB, issued Accounting Standard update, or ASU, 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities , which provides guidance for the recognition, measurement, presentation, and disclosure of financial assets and liabilities. This ASU will be effective for us beginning in the first quarter of 2018. We are currently evaluating the impact of the adoption of this ASU on our financial statements. In February 2016, FASB issued ASU 2016-02, Leases (Topic 842), which supersedes existing guidance on accounting for leases in “Leases (Topic 840)” and generally requires all leases to be recognized in the consolidated balance sheet. ASU 2016-02 is effective for annual and interim reporting periods beginning after December 15, 2018; early adoption is permitted. The provisions of ASU 2016-02 are to be applied using a modified retrospective approach. We are currently evaluating the impact of the adoption of this guidance on our consolidated financial statements. In March 2016, FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting . This ASU affects entities that issue equity-based payment awards to their employees. The ASU is designed to simplify several aspects of accounting for equity-based payment award transactions, which include income tax consequences, classification of awards as either equity or liabilities, classification on the statement of cash flows, and forfeiture rate calculations. ASU 2016-09 will become effective for us beginning in the first quarter of 2017; early adoption is permitted. We are currently evaluating the impact of the adoption of this guidance on our consolidated financial statements. In April 2016, FASB issued an update to ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. The amendments in this update clarify the following two aspects of Topic 606: identifying performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. We are currently evaluating the impact of the adoption of this guidance on our consolidated financial statements.
