Basis of Presentation [Text Block]	BASIS OF PRESENTATION
	The accompanying unaudited condensed consolidated financial statements of Maxim Integrated Products, Inc. and all of its majority-owned subsidiaries (collectively, the “Company” or “Maxim Integrated”) included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with generally accepted accounting principles of the United States of America (“GAAP”) have been condensed or omitted pursuant to applicable rules and regulations. In the opinion of management, all adjustments of a normal recurring nature which were considered necessary for fair presentation have been included. The year-end condensed consolidated balance sheet data were derived from audited consolidated financial statements but do not include all disclosures required by GAAP. The results of operations for the six months ended December 27, 2014 are not necessarily indicative of the results to be expected for the entire year. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Annual Report on Form 10-K for the fiscal year ended June 28, 2014. The Condensed Consolidated Financial Statements included in this Quarterly Report include the financial results of Volterra Semiconductor Corporation (“Volterra”) prospectively from the date of acquisition. Refer to Note 13: “Acquisitions” of these Notes to Condensed Consolidated Financial Statements for further discussion in relation to Volterra.
	The Company has a 52-to-53-week fiscal year that ends on the last Saturday in June. Accordingly, every fifth or sixth fiscal year will be a 53-week fiscal year. Fiscal years 2014 and 2013 were 52-week fiscal years and fiscal year 2015 will also be a 52-week fiscal year.

Recently Issued Accounting Pronouncements [Text Block]	RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
	(i) New Accounting Updates Recently Adopted
	In the first quarter of fiscal year 2015, the Company adopted Accounting Standards Update (“ASU”) No. 2013-11, Income Taxes (Topic 740)-Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which requires certain unrecognized tax benefits to be presented as reductions to deferred tax assets instead of liabilities on the Condensed Consolidated Balance Sheets. The adoption of this standard did not have a material impact on the Company’s Condensed Consolidated Balance Sheets.
	(ii) Recent Accounting Updates Not Yet Effective
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 uses a five-step model to determine revenue recognition in contracts with customers. The Company is currently evaluating the potential impact of this standard on its financial statements. ASU 2014-09 is effective for the Company in our first quarter of fiscal year 2018 using either of two methods: (i) retrospective to each prior reporting period presented with the option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospective with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures as defined per ASU 2014-09.
	In April 2014, the FASB issued ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU 2014-08 redefines discontinued operations as disposals representing a strategic shift in operations and having a major effect on the organization’s operations and financial results. The Company is currently evaluating the potential impact of this standard on its financial statements. The Company will be required to adopt ASU 2014-08 on a prospective basis starting in fiscal year 2016.

Fair_Value_Measurements

Fair Value Measurements	6 Months Ended
	Dec. 27, 2014
Fair Value Disclosures [Abstract]
Fair Value Measurements [Text Block]	FAIR VALUE MEASUREMENTS
	The FASB established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. This hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Three levels of inputs that may be used to measure fair value are as follows:
	Level 1 - Quoted (unadjusted) prices in active markets for identical assets or liabilities.
	The Company’s Level 1 assets consist of money market funds.
	Level 2 - Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.
	The Company's Level 2 assets and liabilities consist of U.S. treasury bills and foreign currency forward contracts that are valued using quoted market prices or are determined using a yield curve model based on current market rates. As a result, the Company has classified these investments as Level 2 in the fair value hierarchy.
	Level 3 - Unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.
	The Company’s Level 3 assets and liabilities consists of contingent consideration liability related to certain prior years’ acquisitions, long-lived assets, goodwill and intangibles when it is recorded at fair value due to an impairment charge.
	Assets and liabilities measured at fair value on a recurring basis were as follows:
		As of December 27, 2014												As of June 28, 2014
		Fair Value										Total		Fair Value						Total

	The tables below present reconciliations for liabilities measured and recorded at fair value on a recurring basis using significant unobservable inputs (Level 3) for the six months ended December 27, 2014 and December 28, 2013:
	Fair Value Measured and Recorded Using Significant Unobservable Inputs (Level 3)

	Ending balance		$	—			$	5,469
	Changes in unrealized losses (gains) included in earnings related to liabilities still held as of period end		$	—			$	1,493
	The valuation of contingent consideration is based on a probability weighted earnout model which relies primarily on estimates of milestone achievements and discount rates applicable for the period expected payout. The most significant unobservable input used in the determination of estimated fair value of contingent consideration is the estimates on the likelihood of milestone achievements, which directly correlates to the fair value recognized in the Condensed Consolidated Balance Sheets.
	The fair value of this liability is estimated quarterly by management based on inputs received from the Company’s engineering and finance personnel. The determination of the milestone achievement is performed by the Company’s business units and reviewed by the accounting department. Potential valuation adjustments are made as the progress toward achieving milestones becomes determinable, with the impact of such adjustments being recorded to Other operating expenses (income), net in our Condensed Consolidated Statements of Income.
	During the six months ended December 27, 2014 and the year ended June 28, 2014, there were no transfers in or out of Level 3 from other levels in the fair value hierarchy.
	There were no assets or liabilities measured at fair value on a non-recurring basis as of December 27, 2014 and June 28, 2014 other than impairments of Long-Lived assets, Goodwill and Intangible assets. For details, please refer to Note 14: “Goodwill & intangible assets” and Note 15: "Impairment of long-lived assets".

	Derivative instruments and hedging activities
	The Company generates revenues in various global markets based on orders obtained in non-U.S. currencies, primarily the Japanese Yen, the Euro and the British Pound. The Company incurs expenditures denominated in non-U.S. currencies, including the Philippine Peso and Thai Baht associated with the Company's manufacturing activities in the Philippines and Thailand, respectively, and expenditures for sales offices and research and development activities undertaken outside of the U.S.

	Derivatives designated as cash flow hedging instruments
	The Company designates certain forward contracts as hedging instruments pursuant to Accounting Standards Codification (“ASC”)
	No. 815-Derivatives and Hedging (“ASC 815”). As of December 27, 2014 and June 28, 2014, respectively, the notional amounts of the forward contracts the Company held to purchase U.S. Dollars in exchange for other international currencies were $62.7 million and $60.6 million, respectively, and the notional amounts of forward contracts the Company held to sell U.S. Dollars in exchange for other international currencies were $2.7 million and $0.8 million, respectively.

	On March 18, 2013, the Company completed a public offering of $500 million aggregate principal amount of the Company’s 3.375% senior unsecured and unsubordinated notes due in March 2023 (“2023 Notes”), with an effective interest rate of 3.5%. Interest on the 2023 Notes is payable semi-annually in arrears on March 15 and September 15 of each year. The net proceeds of this offering were approximately $490.0 million, after issuing at a discount and deducting paid expenses, and are included in the financing activities in the Condensed Consolidated Statements of Cash Flows.
	The Company accounts for all the notes above based on their amortized cost. The discount and expenses are being amortized to Interest and other income (expense), net in the Condensed Consolidated Statements of Income over the life of the notes. Interest expense associated with the notes was $7.4 million and $5.6 million during the three months ended December 27, 2014 and December 28, 2013, respectively. The interest expense is recorded in Interest and other income (expense), net in the Condensed Consolidated Statements of Income.
	The estimated fair value of the Company’s debt was approximately $999 million as of December 27, 2014. The estimated fair value of the debt is based primarily on observable market inputs and is a Level 2 measurement.
	Credit Facility
	The Company has access to a $350 million senior unsecured revolving credit facility with certain institutional lenders that expires on June 27, 2019. The facility fee is at a rate per annum that varies based on the Company's index debt rating and any advances under the credit agreement will accrue interest at a base rate plus a margin based on the Company's index debt rating. The credit agreement requires the Company to comply with certain covenants, including a requirement that the Company maintain a ratio of debt to EBITDA (earnings before interest, taxes, depreciation, and amortization) of not more than 3 to 1 and a minimum interest coverage ratio (EBITDA divided by interest expense) greater than 3.5 to 1. As of December 27, 2014, the Company had not borrowed any amounts from this credit facility and was in compliance with all debt covenants.
	Other Financial Instruments
	For the balance of the Company’s financial instruments, cash equivalents, accounts receivable, accounts payable and other accrued liabilities, the carrying amounts approximate fair value due to their short maturities.

	Stock Options
	The fair value of options granted to employees under the Company’s Amended and Restated 1996 Stock Incentive Plan is estimated on the date of grant using the Black-Scholes option valuation model.
	Expected volatilities are based on the historical volatilities from the Company’s traded common stock over a period equal to the expected term. The Company is utilizing the simplified method to estimate expected holding periods. The risk-free interest rate is based on the U.S. Treasury yield. The Company determines the dividend yield by dividing the annualized dividends per share by the prior quarter’s average stock price. The Company also estimates forfeitures at the time of grant and makes revisions to forfeitures on a quarterly basis.
	The fair value of options granted to employees has been estimated using the following weighted-average assumptions:
		Stock Options
		Three Months Ended						Six Months Ended
		December 27,			December 28,			December 27,			December 28,
		2014			2013			2014			2013
	Expected holding period (in years)	5			5			4.8			5.3
	Risk-free interest rate	1.7	%		1.5	%		1.6	%		1.4	%
	Expected stock price volatility	26.8	%		34.1	%		26.7	%		34.9	%
	Dividend yield	3.5	%		3.7	%		3.2	%		3.2	%
	The weighted-average fair value of stock options granted was $4.79 and $9.15 per share for the three months ended December 27, 2014 and December 28, 2013, respectively. The weighted-average fair value of stock options granted was $5.56 and $7.44 per share for the six months ended December 27, 2014 and December 28, 2013, respectively.
	The following table summarizes outstanding, exercisable and vested and expected to vest stock options as of December 27, 2014 and their activity for the six months ended December 27, 2014:
		Number of			Weighted Average Exercise Price				Weighted Average Remaining Contractual Term (in Years)		Aggregate Intrinsic Value (1)
		Shares
	Balance at June 28, 2014	16,163,644			$	25.74

	Vested and expected to vest, December 27, 2014	13,060,118			$	24.96			3.4		$	92,492,587
	-1	Aggregate intrinsic value represents the difference between the exercise price and the closing price per share of the Company’s common stock on December 26, 2014, the last business day preceding the fiscal quarter-end, multiplied by the number of options outstanding, exercisable or vested and expected to vest as of December 27, 2014.
	As of December 27, 2014, there was $27.2 million of total unrecognized stock compensation cost related to 7.1 million unvested stock options, which is expected to be recognized over a weighted average period of approximately 2.3 years.
	As of December 28, 2013, there was $45.1 million of total unrecognized stock compensation cost related to 11.1 million unvested stock options, which is expected to be recognized over a weighted average period of approximately 3.0 years.
	Restricted Stock Units
	The fair value of Restricted Stock Units (“RSUs”) under the Company’s Amended and Restated 1996 Stock Incentive Plan is estimated using the value of the Company’s common stock on the date of grant, reduced by the present value of dividends expected to be paid on the Company’s common stock prior to vesting. The Company also estimates forfeitures at the time of grant and makes revisions to forfeitures on a quarterly basis.
	The weighted-average fair value of RSUs granted was $27.24 and $28.16 per share for the three months ended December 27, 2014 and December 28, 2013, respectively.
	The weighted-average fair value of RSUs granted was $27.18 and $26.08 per share for the six months ended December 27, 2014 and December 28, 2013, respectively.
	The following table summarizes outstanding and expected to vest RSUs as of December 27, 2014 and their activity during the six months ended December 27, 2014:
		Number of			Weighted Average		Aggregate Intrinsic
		Shares			Remaining		Value (1)
					Contractual Term

	Restricted stock units cancelled	(648,653	)
	Balance at December 27, 2014	8,487,069			2.9		$	267,916,927
	Outstanding and expected to vest, December 27, 2014	7,349,984			2.8		$	229,319,498
-1	Aggregate intrinsic value for RSUs represents the closing price per share of the Company’s common stock on December 26, 2014, the last business day preceding the fiscal quarter-end, multiplied by the number of RSUs outstanding or expected to vest as of December 27, 2014.
The Company withheld shares totaling $6.8 million and $14.9 million in value as a result of employee withholding taxes based on the value of the RSUs on their vesting date for the three and six months ended December 27, 2014, respectively. The total payments for the employees’ tax obligations to the taxing authorities are reflected as financing activities within the Condensed Consolidated Statements of Cash Flows.
As of December 27, 2014, there was $159.5 million of unrecognized compensation expense related to 8.5 million unvested RSUs, which is expected to be recognized over a weighted average period of approximately 2.9 years.
As of December 28, 2013, there was $153.1 million of unrecognized compensation expense related to 9.2 million unvested RSUs, which is expected to be recognized over a weighted average period of approximately 2.9 years.
Market Stock Units
The Company began granting Market Stock Units (“MSUs”) to senior members of management in September 2014 instead of stock options. MSUs are valued based on the relative performance of the Company’s stock price as compared to the Semiconductor Exchange Traded Fund index, (the “SPDR S&P”). The fair value of MSUs is estimated using a Monte Carlo simulation model on the date of grant. The Company also estimates forfeitures at the time of grant and makes revisions to forfeitures on a quarterly basis. Compensation expense is recognized based on the initial valuation and is not subsequently adjusted as a result of the Company’s performance relative to that of the SPDR S&P index.
The following table summarizes the number of MSUs outstanding and expected to vest as of December 27, 2014 and their activity during the six months ended December 27, 2014:
	Number of				Weighted Average		Aggregate Intrinsic
	Shares				Remaining		Value (1)
					Contractual Term
					(in Years)
Balance at June 28, 2014	120,000		(2	)

Market stock units cancelled	(20,532	)
Balance at December 27, 2014	480,036				3.5		$	14,977,123
Outstanding and expected to vest, December 27, 2014	480,036				3.5		$	14,977,123
-1	Aggregate intrinsic value for MSUs represents the closing price per share of the Company’s common stock on December 26, 2014, the last business day preceding the fiscal quarter-end, multiplied by the number of MSUs outstanding or expected to vest as of December 27, 2014.
-2	Reflects shares previously granted to the Company’s Chief Executive Officer only.
As of December 27, 2014, there was $6.4 million of unrecognized compensation expense related to 0.5 million unvested MSUs, which is expected to be recognized over a weighted average period of approximately 3.5 years.
As of December 28, 2013, there was $1.6 million of unrecognized compensation expense related to 0.1 million unvested MSUs, which is expected to be recognized over a weighted average period of approximately 1.3 years.
Employee Stock Purchase Plan
The fair value of rights to acquire common stock under the Company’s 2008 Employee Stock Purchase Plan (the “ESPP”) is estimated on the date of grant using the Black-Scholes option valuation model.
The fair value of ESPP granted to employees has been estimated at the date of grant using the Black-Scholes option valuation model and the following weighted-average assumptions:
	ESPP
	Three Months Ended						Six Months Ended
	December 27,			December 28,			December 27,			December 28,
	2014			2013			2014			2013

Earnings Per Share [Abstract]
Earnings Per Share [Text Block]	EARNINGS (LOSS) PER SHARE
	Basic earnings (loss) per share are computed using the weighted average number of shares of common stock outstanding during the period. For purposes of computing basic earnings (loss) per share, the weighted average number of outstanding shares of common stock excludes unvested RSUs and MSUs. Diluted earnings (loss) per share incorporates the incremental shares issuable upon the assumed exercise of stock options, assumed release of unvested RSUs and MSUs and assumed issuance of common stock under the employee stock purchase plans using the treasury stock method.
	The following table sets forth the computation of basic and diluted earnings (loss) per share:
		Three Months Ended					Six Months Ended
		December 27,			December 28,		December 27,		December 28,
		2014			2013		2014		2013

	Diluted	$	(0.25	)	$	0.15	$	0.1	$	0.51
	The Company had a net loss for the three months ended December 27, 2014, accordingly all incremental shares totaling 5.8 million shares were determined to be anti-dilutive. Approximately 10.5 million stock options were excluded from the calculation of diluted earnings per share for the three months ended December 28, 2013. Approximately 5.9 million and 9.8 million stock options were excluded from the calculation of diluted earnings per share for the six months ended December 27, 2014 and December 28, 2013, respectively. These options were excluded because they were determined to be anti-dilutive. However, such options could be dilutive in the future and, under those circumstances, would be included in the calculation of diluted earnings per share.

Segment Reporting [Abstract]
Segment Information [Text Block]	SEGMENT INFORMATION
	The Company operates and tracks its results in one reportable segment. The Company designs, develops, manufactures and markets a broad range of linear and mixed signal integrated circuits. The Chief Executive Officer has been identified as the Chief Operating Decision Maker as defined by ASC No. 280, Segment Reporting (“ASC 280”).
	The Company has three operating segments that aggregate into one reportable segment. Under ASC 280, two or more operating segments may be aggregated into a single operating segment for financial reporting purposes if aggregation is consistent with the objective and basic principles of ASC 280, if the segments have similar economic characteristics, and if the segments are similar in each of the following areas:
	•	the nature of products and services;
	•	the nature of the production processes;
	•	the type or class of customer for their products and services; and
	•	the methods used to distribute their products or provide their services.
	The Company meets each of the aggregation criteria for the following reasons:
	•	the sale of analog and mixed signal integrated circuits is the primary source of revenue for each of the Company’s three operating segments;
	•	the integrated circuits sold by each of the Company’s operating segments are manufactured using similar semiconductor manufacturing processes;
	•	the integrated circuits marketed by each of the Company’s operating segments are sold to the same types of customers; and
	•	all of the Company’s integrated circuits are sold through a centralized sales force and common wholesale distributors.
	All of the Company’s operating segments share similar long-term financial performance as they have similar economic characteristics, including gross margins. The causes for variation among the Company’s operating segments are the same and include factors such as (i) life cycle and price and cost fluctuations, (ii) number of competitors, (iii) product differentiation and (iv) size of market opportunity. Additionally, each operating segment is subject to the overall cyclical nature of the semiconductor industry. The number and composition of employees and the amounts and types of tools and materials required are similar for each operating segment. Finally, even though the Company periodically reorganizes the Company’s operating segments based upon changes in customers, end-markets or products, acquisitions, long-term growth strategies, and the experience and bandwidth of the senior executives in charge, the common financial goals for each operating segment remain constant.
	Enterprise-wide information is provided in accordance with ASC 280. Geographical revenue information is based on customers’ ship-to location. Long-lived assets consist of property, plant and equipment. Property, plant and equipment information is based on the physical location of the assets at the end of each reporting period.

Income Tax Disclosure [Abstract]
Income Taxes [Text Block]	INCOME TAXES
	In the three and six months ended December 27, 2014, the Company recorded an income tax provision (benefit) of $0.4 million and $(5.1) million, respectively, compared to $20.2 million and $42.2 million in the three and six months ended December 28, 2013, respectively. The Company’s effective tax rate for the three and six months ended December 27, 2014 was 0.5% and (22.5)%, respectively, compared to 31.3% and 22.3% for the three and six months ended December 28, 2013, respectively.
	The Company's federal statutory tax rate is 35%. The Company's effective tax rate for the three months ended December 27, 2014 was higher than the statutory rate primarily because of a $84.1 million discrete goodwill impairment charge that generated no tax benefit and stock-based compensation for which no tax benefit is expected, partially offset by earnings of foreign subsidiaries, generated primarily by our international operations managed in Ireland, taxed at lower tax rates and a $2.9 million discrete benefit for fiscal year 2014 research tax credits that were generated by the retroactive extension of the federal research tax credit to January 1, 2014 by legislation that was signed into law on December 19, 2014.
	The Company’s effective tax rate for the six months ended December 27, 2014 was lower than the statutory tax rate primarily because earnings of foreign subsidiaries, generated primarily by our international operations managed in Ireland, were taxed at lower rates, a $2.9 million discrete benefit for fiscal year 2014 research tax credits that were generated by the retroactive extension of the federal research tax credit to January 1, 2014 by legislation that was signed into law on December 19, 2014 and a $24.8 million discrete benefit for the favorable settlement of a Singapore tax issue in the first quarter of fiscal year 2015, partially offset by an $84.1 million discrete goodwill impairment charge that generated no tax benefit and stock-based compensation for which no tax benefit is expected.
	The Company’s effective tax rates for the three and six months ended December 28, 2013 were lower than the statutory tax rate primarily because earnings of foreign subsidiaries, generated primarily by our international operations managed in Ireland, were taxed at lower rates, partially offset by stock-based compensation for which no tax benefit is expected.
	The Company’s federal corporate income tax returns are audited on a recurring basis by the IRS. In fiscal year 2012 the U.S. Internal Revenue Service commenced an audit of the Company's federal corporate income tax returns for fiscal years 2009 through 2011, which is still ongoing.

Commitments and Contingencies [Text Block]	COMMITMENTS AND CONTINGENCIES
	Legal Proceedings
	The Company is a party or subject to various legal proceedings and claims, either asserted or unasserted, which arise in the ordinary course of business, including proceedings and claims that relate to intellectual-property matters. While the outcome of these matters cannot be predicted with certainty, we do not believe that the outcome of any of these matters, individually or in the aggregate, will result in losses that are materially in excess of amounts already recognized or reserved, if any.
	Indemnification
	The Company indemnifies certain customers, distributors, suppliers and subcontractors for attorney fees and damages and costs awarded against such parties in certain circumstances in which the Company’s products are alleged to infringe third party intellectual property rights, including patents, registered trademarks or copyrights. The terms of the Company’s indemnification obligations are generally perpetual from the effective date of the agreement. In certain cases, there are limits on and exceptions to the Company’s potential liability for indemnification relating to intellectual property infringement claims.
	Pursuant to the Company’s charter documents and separate written indemnification agreements, the Company has certain indemnification obligations to its current officers, employees and directors, as well as certain former officers and directors.
	Product Warranty
	The Company generally warrants its products for one year from the date of shipment against defects in materials, workmanship and material non-conformance to the Company’s specifications. The general warranty policy provides for the repair or replacement of defective products or a credit to the customer’s account. In addition, the Company may consider its relationship with the customer when reviewing product warranty claims. In limited circumstances and for strategic customers in certain unique industries and applications, our product warranty may extend for up to five years, and may also include financial responsibility, such as the payment of monetary compensation to reimburse a customer for its financial losses above and beyond repairing or replacing the product or crediting the customer’s account should the product not meet the Company’s specifications and losses and /or damages results from the defective product.
	Accruals are based on specifically identified claims and on the estimated, undiscounted cost of incurred-but-not-reported claims. If there is a material increase in the rate of customer claims compared with our historical experience or if the Company's estimates of probable losses relating to specifically identified warranty exposures require revision, the Company may record a charge against future cost of sales.

Business Combination Disclosure [Text Block]	ACQUISITIONS
	Acquisitions completed in fiscal year 2014
	The Company completed two acquisitions during fiscal year 2014.
	VOLTERRA SEMICONDUCTOR CORPORATION
	On October 1, 2013, the Company completed its acquisition of Volterra Semiconductor Corporation ("Volterra"), formerly a publicly traded company that develops power management solutions. The primary reason for this acquisition was to expand the Company's available market across a wide range of end markets, including enterprise server, cloud computing, communications and energy. The results of operations of Volterra are included in the Company’s Condensed Consolidated Statements of Income, beginning in the second quarter of fiscal year 2014. Acquisition-related costs for the twelve months ended June 28, 2014were $7.0 million.
	The total purchase price for Volterra was approximately $615 million and was comprised of:
			(in thousands)
	Cash consideration for 100% of outstanding common stock of Volterra at $23 per share		$	593,250
	Cash consideration for vested options settlement		21,756
	Total purchase price		$	615,006
	The purchase price allocation as of the date of the acquisition is set forth in the table below and reflects various fair value estimates and analysis. These estimates were determined through established and generally accepted valuation techniques, including preliminary work performed by third-party valuation specialists.

	IPR&D assets relate to future technology, is capitalized until the technology is ready for its intended use and then amortized over the technology useful life. IPR&D costs incurred by the Company subsequent to the acquisition are expensed.
	Goodwill was primarily attributable to the opportunities from the addition of Volterra's product portfolio which complements the Company’s suite of products, including providing integrated process solutions to customers. The goodwill is not deductible for tax purposes.
	The amortizable intangible assets are being amortized on a straight-line basis over their estimated useful lives as follows:
		Volterra Acquisition
		Fair Value			Weighted Average Useful Life (in years)
		(in thousands)
	Intellectual property	$	192,500		4.9

	Patents	2,500			4.8
	Total amortizable intangible assets	$	226,900
	Pro forma results of operations for this acquisition have not been presented because it is not material to the Company's Condensed Consolidated Statements of Income.
	OTHER ACQUISITION
	The Company acquired another company during the fiscal year ended June 28, 2014, which develops low power high performance analog circuits. The total cash consideration paid to acquire this company was approximately $6.1 million for which the purchase price was largely attributable to the developed intellectual property. Goodwill associated with this acquisition was $0.5 million. Acquisition related costs were not material for this transaction.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets [Text Block]	GOODWILL AND INTANGIBLE ASSETS
	Goodwill
	The Company monitors the recoverability of goodwill recorded in connection with acquisitions, by reporting unit, annually, or more often if events or changes in circumstances indicate that the carrying amount may not be recoverable. The Company performed the annual goodwill impairment analysis during the first quarter of fiscal year 2015 and concluded that goodwill was not impaired, as the fair value of each reporting unit exceeded its carrying value.
	During the quarter ended December 27, 2014, goodwill for the Sensing Solutions reporting unit was determined to be impaired and the Company recorded a charge of $84.1 million. The Sensing Solutions reporting unit develops integrated circuits which are primarily sold in the consumer and automotive end customer markets. The impairment was the result of the Company's decision within the quarter ended December 27, 2014 to exit certain market offerings that have competitive dynamics which are no longer consistent with the Company’s business objectives.
	The Company determined that sufficient indicators of potential impairment existed to require an interim goodwill impairment analysis for the Sensing Solutions reporting unit. The reporting unit's carrying value exceeded its estimated fair value, accordingly a second phase of the goodwill impairment test (“Step 2”) was performed. Under Step 2, the fair value of all Sensing Solution’s assets and liabilities were estimated, including tangible assets and intangible assets (including existing and in-process technology) for the purpose of deriving an estimate of the implied fair value of goodwill. The implied fair value of the goodwill was then compared to the carrying value of the goodwill to determine the amount of the impairment.
	The Company estimated the fair value of the Sensing Solutions reporting unit using a weighting of fair values derived equally from the income and market approach. Under the income approach, the Company calculates the fair value of a reporting unit based on the present value of estimated future cash flows. Cash flow projections are based on management's estimates of revenue growth rates and operating margins, taking into consideration industry and market conditions. The discount rate used is based on the weighted-average cost of capital adjusted for the relevant risk associated with business-specific characteristics and the uncertainty related to the business's ability to execute on the projected cash flows. The market approach estimates fair value based on market multiples of revenue and earnings derived from comparable publicly-traded companies with similar operating and investment characteristics as the reporting unit.
	Prior to completing the goodwill impairment test, the Company tested the recoverability of the Sensing Solutions long-lived assets (other than goodwill) and concluded that existing Property, plant and equipment, net was impaired by $45.2 million and IPR&D was impaired by $8.9 million.
	No other indicators or instances of impairment were identified in the quarter ended December 27, 2014.

impairment of long life assets [Abstract]
Impairment of Long Lived Assets Disclosure [Text Block]	IMPAIRMENT OF LONG-LIVED ASSETS
	Fiscal year 2015:
	During the second quarter of fiscal year 2015, the Company recorded $50.7 million in impairment of long-lived assets in the Company's Condensed Consolidated Statements of Income.
	The impairment was primarily related to the write down of equipment relating to the Sensing Solutions reporting unit of $45.2 million. For background, please refer to Note 14: “Goodwill & intangible assets”. The Company reached its conclusion regarding the asset impairment after concluding that the undiscounted cash flows fell below the net book value of the net assets of the Sensing Solutions reporting unit (the asset group). As a result, the Company reduced the assets to their fair value after conducting an evaluation of each asset’s alternative use, the condition of the asset and the current market pricing and demand.
	During the first quarter of fiscal year 2015, the Company recorded $10.2 million in impairment of long-lived assets in the Company's Condensed Consolidated Statements of Income.
	This impairment was primarily related to used fabrication tools identified by the Company as obsolete in the three months ended September 27, 2014 due to the transition to newer technologies. The Company reached its conclusion regarding the asset impairment after conducting an evaluation of alternative use, the condition of the assets and current market demand.
	Fiscal year 2014:
	During the second quarter of fiscal year 2014, the Company recorded $5.2 million in Impairment of long-lived assets in the Company's Condensed Consolidated Statements of Income.
	The impairment includes certain U.S. test operation assets identified as excess and no longer needed. These assets included primarily test manufacturing equipment which was recorded in Property, plant, and equipment, net in the Condensed Consolidated Balance Sheet as of June 28, 2014. The company also impaired fab tools and a building classified as held for sale. The fab tools were fully impaired while the building was impaired down to fair value less cost to sell. The fair value of the building was determined mainly after consideration of evidence such as broker estimates, building condition, and offers received.

	San Jose Fab Shutdown
	On October 23, 2014, the Company initiated a plan to shut down its San Jose wafer fabrication facility. The Company reached the decision that it was not economically feasible to maintain this facility, which is used primarily for fab process development and low volume manufacturing, as the Company intends to utilize other resources to complete such activities in the future. This plan includes cash charges related to employee severance and non-cash charges related to accelerated depreciation.
	During the three and six months ended December 27, 2014, respectively, the Company recorded accelerated depreciation charges of $8.9 million in "Cost of goods sold" and $6.0 million in "Severance and restructuring expenses" in the Condensed Consolidated Statement of Income. The expected total cost of the plan is approximately $87.8 million and it is expected to be complete by the end of fiscal year 2016.
	Other Plans
	During the six months ended December 27, 2014, the Company recorded $8.6 million in "Severance and restructuring expenses" in the Condensed Consolidated Statement of Income related to various restructuring plans designed to reduce costs. These charges were associated with the reorganization of certain business units and functions. Multiple job classifications and locations were impacted by these activities.
	The Company also accrued for expected losses relating to lease terminations as a result of plans to consolidate office space. The need for consolidation resulted from acquisition and relocation activities.
	Fiscal year 2014:
	Volterra Restructuring Plan
	In connection with the acquisition of Volterra, the Company's management approved and initiated plans to restructure the operations of Volterra, including acceleration of certain stock-based compensation awards, costs to vacate duplicative facilities, severance for transitional and exiting employees, contract cancellation costs and other items. The total combined cost of the plan was $9.9 million in Severance and restructuring expenses in the Company's Condensed Consolidated Statements of Income. As of December 28, 2013, the Company recorded all of the costs of the plan based upon the anticipated timing of planned terminations and facility closure costs. Expected severance and retention costs for transitional employees are being accrued over the transitional period. Amounts accrued and future estimated costs to be incurred as of December 28, 2013 are immaterial.
	Business Unit Reorganization
	During the six months ended December 28, 2013, the Company recorded $5.9 million in Severance and restructuring expenses in the Company's Condensed Consolidated Statements of Income associated with the reorganization of certain business units. Multiple job classifications and locations were impacted as this was a company-wide action. The reorganization was driven by the desire to focus on specific investment areas and simplify business processes.
