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 solutions. Our products address some of the largest markets within the industrial and infrastructure, consumer and computing, and high-end consumer markets.
	In our opinion, these interim 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 2, 2015 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 fiscal year ended January 2, 2015.
	We utilize a 52/53 week fiscal year, ending on the nearest Friday to December 31. The next 53 week period will be in the second quarter of our fiscal year 2018. Quarterly or annual periods vary from exact calendar quarters or years.
	Recent Accounting Guidance Not Yet Adopted
	On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is expected to be effective for Intersil for the fiscal year after December 15, 2017.  We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.

Fair_Value_Measurements

Fair Value Measurements	3 Months Ended

Fair Value Measurements [Abstract]
Fair Value Measurements	Note 2 — 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 April 3, 2015 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	$	11,013	$	686	$	10,327
	Total assets measured at fair value	$	11,013	$	686	$	10,327
		Fair value as of January 2, 2015 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	$	11,144	$	353	$	10,791
	Total assets measured at fair value	$	11,144	$	353	$	10,791
	There were no transfers into or out of Level 1, Level 2, or Level 3 financial assets during the quarters ended April 3, 2015 and April 4, 2014.

Goodwill And Purchased Intangibles [Abstract]
Goodwill And Purchased Intangibles
	Note 4 — Goodwill and Purchased Intangibles
	Goodwill — We perform our annual test of impairment in our fiscal 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. During our fiscal quarter ended April 3, 2015, we made certain organizational changes which resulted in a reorganization from four reporting units – specialty, mobile, precision, and industrial & infrastructure – into three reporting units – mobile, precision, and industrial & infrastructure.  As a result of this reorganization, we performed a fair value analysis immediately prior to the reallocation. In addition, we reallocated our existing goodwill balances to the new reporting units utilizing a relative fair value allocation approach in accordance with FASB ASC Topic 350. Based on our analyses, no impairment was indicated, and consequently, there was no change in the consolidated carrying value of goodwill during the fiscal quarter ended April 3, 2015.
	Purchased Intangibles — Substantially all of our purchased intangibles consist of multiple elements of developed technology which have estimated useful lives of five years. Other purchased intangibles consist primarily of customer relationships and other identifiable assets, which have an estimated useful life of four to seven years (in thousands).

Restructuring and Related Costs [Abstract]
Restructuring and Related Costs	Note 5 — Restructuring and Related Costs
	Our restructuring plans have been described in prior period filings. During the quarter ended April 3, 2015 no new restructuring plans were initiated.
	The restructuring and related costs balance as of the period ended April 3, 2015 primarily relates to the July 2013 plan. The balance outstanding was $0.7 million as of April 3, 2015 and January 2, 2015, respectively, and is included in “Other accrued expenses and liabilities” on the unaudited condensed consolidated balance sheet.

Income Taxes [Abstract]
Income Taxes
	Note 6 — Income Taxes
	Income tax expense was $5.5 million, an effective tax rate of negative 8.74%, for the quarter ended April 3, 2015 compared to an income tax expense of $4.6 million, an effective tax rate of 32.12%, for the quarter ended April 4, 2014.
	The effective tax rate is negative for the fiscal quarter ended April 3, 2015, primarily due to losses in foreign jurisdictions related to the TAOS litigation.  The $79.5 million accrual recorded for the TAOS litigation is being treated as an unusual and discrete item for the quarter, for which the future tax benefit is $1.2 million, and the loss was allocated primarily to our Malaysian operations.
	The effective tax rate differs from the 35% statutory corporate tax rate primary due to (losses) income in foreign jurisdictions, primarily in Malaysia, with lower statutory tax rates and permanent non-deductible items, such as equity based compensation associated with our cost sharing arrangement.
	We have various uncertain tax positions and have estimated an ultimate resolution of those positions.  The table below summarizes activity in gross unrecognized tax benefits (“UTBs”) (in thousands):
	Beginning balance (includes $7,538 of interest and penalties)	$	78,206
	Increases related to current year tax positions		0
	Increases related to prior year tax positions		289
	Settlements with tax authorities		-500
	Ending balance (includes $7,844 of interest and penalties)	$	77,995
	The increases related to prior year tax positions were primarily due to accrued interest on the UTBs. The settlements are primarily related to tax and interest paid on the amended state income tax returns filed due to the 2008 -2011 IRS audit adjustments.
	We believe events that could occur in the next 12 months and cause a material change in unrecognized tax benefits include, but are not limited to, the following:
		·		Completion of examinations by the U.S. or foreign tax authorities; or
		·		Expiration of statute of limitations on our tax returns.
	The calculation of unrecognized tax benefits involves dealing with uncertainties in the application of complex global tax regulations.  We regularly assess our tax positions in light of legislative, bilateral tax treaty, regulatory, tax holiday arrangements and judicial developments in the countries in which we do business.  We believe it is reasonably possible that we may recognize $20 million of our existing unrecognized tax benefits (net of prepaid taxes) within the next 12 months as a result of the lapse of statutes of limitations or the resolution of agreements with domestic and various foreign tax authorities.
	Additional Paid in Capital (“APIC”) Pool—The APIC pool represents the excess tax benefits related to equity-based compensation that are available to absorb future tax deficiencies.  If the amount of tax deficiencies is greater than the available APIC pool from prior years, we record the excess as income tax expense in our unaudited condensed consolidated statements of operations.  During the quarter ended April 3, 2015, we recognized $0.7 million of income tax expense resulting from tax deficiencies related to equity-based compensation in our unaudited condensed consolidated statements of operations. During the quarter ended April 4, 2014, we recognized $0.4 million of income tax expense resulting from tax deficiencies related to equity-based compensation in our unaudited condensed consolidated statements of operations.

Long-Term Debt	Note 7 — Long-Term Debt
	We have a five-year, $325.0 million revolving credit facility (the “Facility”) that matures on September 1, 2016 and is payable in full upon maturity.

Litigation Matters And Indemnifications
	Note 12 — Legal Matters and Indemnifications
	Legal Matters — Texas Advanced Optoelectronic Solutions, Inc. (“TAOS”) named Intersil 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 a federal jury found in TAOS’ favor on each of the four claims.  The jury also recommended to the trial judge that Intersil pay $48.7 million in actual damages and $10.0 million in exemplary damages on the trade secret misappropriation claim which TAOS has elected along with $74 thousand in damages for patent infringement. After the trial, TAOS filed post-trial motions seeking unspecified attorneys’ fees, enhanced patent infringement damages, $18.1 million in pre-trial interest on the jury award and a permanent injunction enjoining us from making or selling certain ambient light sensor products. We intend to vigorously oppose each of these motions and believe that there are good grounds for overturning the jury verdict through post-trial motions and, if necessary, appeals to the U.S. Court of Appeals for the Federal Circuit.
	As a consequence of the verdict, we recorded a provision of $81.1 million related to this matter, including estimated legal costs. During the quarter we incurred $1.6 million of legal costs, as such the accrual outstanding as of April 3, 2015 was $79.5 million. Given the unpredictable nature of this type of litigation and because the outcome remains subject to post-trial motions and appeal, the ultimate impact of this lawsuit may be materially different from our estimate.
	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.
	Please reference our 2014 Annual Report on Form 10-K filed with the SEC on February 12, 2015 for additional details and other legal matters.
	Indemnifications — 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.

Basis Of Presentation [Abstract]
Fiscal Period	We utilize a 52/53 week fiscal year, ending on the nearest Friday to December 31. The next 53 week period will be in the second quarter of our fiscal year 2018. Quarterly or annual periods vary from exact calendar quarters or years.
Recent Accounting Guidance Not Yet Adopted	Recent Accounting Guidance Not Yet Adopted
	On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is expected to be effective for Intersil for the fiscal year after December 15, 2017.  We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.
