New Accounting Pronouncements and Changes in Accounting Principles [Abstract] | |
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09- Revenue from Contracts with Customers , which will supersede nearly all existing revenue recognition guidance under US GAAP. The standard's core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The Company is evaluating its existing revenue recognition policies to determine whether any contracts in the scope of the guidance will be materially affected by the new requirements. The effects may include identifying performance obligations in existing arrangements, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. On July 9, 2015, the FASB delayed the effective date of the new standard by one year to December 15, 2017, for annual and interim reporting periods beginning after that date. In accordance with the delay, the new standard will be effective for the Company beginning no later than April 1, 2018. Early adoption is permitted, but not before the original effective date of December 15, 2016. The standard allows for either "full retrospective" adoption, meaning the standard is applied to all of the periods presented, or "modified retrospective" adoption, meaning the standard is applied only to the most current period presented in the financial statements. The Company is currently evaluating the transition method that will be elected, and the effects of the new standard on its results of operations. In April 2015, the FASB issued ASU 2015-03- Simplifying the Presentation of Debt Issuance Costs. This standard amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of as a deferred charge. ASU 2015-03 is effective for interim and annual reporting periods beginning after December 15, 2015 and requires retrospective application. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-05- Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) , Customer's Accounting for Fees Paid in a Cloud Computing Arrangement . This standard provides guidance about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the software license element of the arrangement should be accounted for consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. ASU 2015-05 is effective for interim and annual reporting periods beginning after December 15, 2015. This standard can be adopted either prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements. In July 2015, the FASB issued ASU 2015-11- Simplifying the Measurement of Inventory. This standard requires that entities measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. ASU 2015-11 is effective for interim and annual reporting periods beginning after December 15, 2016 and is applied prospectively. Early adoption is permitted. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements. In September 2015, the FASB issued ASU 2015-16- Business Combinations (Topic 805), Simplifying the Accounting for Measurement-Period Adjustments . This standard amends existing guidance to require acquiring entities in a business combination to recognize measurement-period adjustments in the reporting period in which the adjustment amounts are determined. The standard also requires entities to present separately on the face of the income statement (or disclose in the notes to the financial statements) the amount of the adjustment reflected in the current period earnings, by line item, that would have been recognized in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The standard is to be applied prospectively to measurement-period adjustments that occur after the effective date. The Company adopted this standard beginning in the second quarter of fiscal 2016 and the adoption of this standard did not have a material impact on its consolidated financial statements. In November 2015, the FASB issued ASU 2015-17- Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. The new guidance requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. The guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016, with early adoption permitted. In the third quarter ended December 31, 2015, the new guidance was adopted on a prospective basis by the Company; accordingly, prior period amounts in the Company's condensed consolidated balance sheet within this quarterly report on Form 10-Q were not adjusted to conform to the new accounting standard. The adoption of this accounting standard was not material to the Company's condensed consolidated financial statements. In January 2016, the FASB issued ASU 2016-01- Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities . This standard addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. ASU 2016-01 is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is not permitted. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements. |

Business Combinations [Abstract] | |
Business Acquisitions | Business Acquisitions Acquisition of Micrel On August 3, 2015, the Company acquired Micrel, Incorporated (Micrel), a publicly traded company based in San Jose, California. The Company paid an aggregate of approximately $ 430.0 million in cash and issued an aggregate of 8,626,795 shares of its common stock to Micrel shareholders. The total consideration transferred in the acquisition, including approximately $ 4.1 million of non cash consideration for the exchange of certain share-based payment awards of Micrel for stock awards of the Company, and approximately $ 13.1 million of cash consideration for the payout of vested employee stock awards, was approximately $ 816.2 million . The Company financed the cash portion of the purchase price using borrowings under its existing credit agreement. As a result of the acquisition, Micrel became a wholly owned subsidiary of the Company. Micrel's business is to design, develop, manufacture and market a range of high-performance analog, power and mixed-signal integrated circuits. Micrel's products address a wide range of end markets including industrial and automotive, wireline communications, enterprise and cloud infrastructure and mobility. Micrel also manufactures custom analog and mixed-signal circuits and provides wafer foundry services for customers which produce electronic systems utilizing semiconductor manufacturing processes as well as micro-electrical mechanical system technologies. The Company's primary reason for this acquisition was to expand the Company's range of solutions, products and capabilities by extending its served available market. The acquisition was accounted for under the acquisition method of accounting, with the Company identified as the acquirer, and the operating results of Micrel have been included in the Company's condensed consolidated financial statements as of the closing date of the acquisition. Under the acquisition method of accounting, the aggregate amount of consideration paid by the Company was allocated to Micrel's net tangible assets and intangible assets based on their estimated fair values as of August 3, 2015. The excess of the purchase price over the value of the net tangible assets and intangible assets was recorded to goodwill. The factors contributing to the recognition of goodwill were based upon the Company's conclusion that there are strategic and synergistic benefits that are expected to be realized from the acquisition. The goodwill has been allocated to the Company's semiconductor products reporting segment. None of the goodwill related to the Micrel acquisition is deductible for tax purposes. The Company retained an independent third-party appraiser to assist management in its valuation; however, the purchase price allocation has not been finalized. This could result in adjustments to the fair values of the assets acquired and liabilities assumed, the useful lives of intangible assets, the residual amount allocated to goodwill and deferred income taxes recognized. The preliminary allocation of the purchase price is based on the best estimates of management and is subject to revision based on the final valuations and estimates of useful lives. The table below represents the preliminary allocation of the purchase price, including adjustments to the initial preliminary purchase price allocation as previously reported at September 30, 2015, to the net assets acquired based on their estimated fair values as of August 3, 2015, as well as the associated estimated useful lives of the acquired intangible assets at that date (amounts in thousands): Assets acquired Previously Reported September 30, 2015 Adjustments December 31, 2015 Cash and cash equivalents $ 99,196 $ — $ 99,196 Accounts receivable, net 12,296 1,800 14,096 Inventories 78,967 (5,499 ) 73,468 Prepaid expenses and other current assets 10,548 217 10,765 Property, plant and equipment, net 38,566 — 38,566 Goodwill 437,060 2,507 439,567 Purchased intangible assets 274,800 (1,300 ) 273,500 Other assets 4,268 — 4,268 Total assets acquired 955,701 (2,275 ) 953,426 Liabilities assumed Accounts payable (11,068 ) — (11,068 ) Other current liabilities (30,241 ) — (30,241 ) Deferred tax liabilities (88,796 ) 343 (88,453 ) Long-term income tax payable (9,239 ) 1,932 (7,307 ) Other long-term liabilities (127 ) — (127 ) Total liabilities assumed (139,471 ) 2,275 (137,196 ) Purchase price allocated $ 816,230 $ — $ 816,230 Purchased Intangible Assets Useful Life August 3, 2015 (in years) (in thousands) Core/developed technology 10 $ 175,800 In-process technology 10 21,000 Customer-related 5 71,100 Backlog 1 5,600 Total purchased intangible assets $ 273,500 Purchased intangible assets include core and developed technology, in-process research and development, customer-related intangibles and acquisition-date backlog. The estimated fair values of the core and developed technology and in-process research and development were determined based on the present value of the expected cash flows to be generated by the respective existing technology or future technology. The core and developed technology intangible assets are being amortized commensurate with the expected cash flows used in the initial determination of fair value. In-process technology is capitalized until such time the related projects are completed or abandoned at which time the capitalized amounts will begin to be amortized or written off. Customer-related intangible assets consist of Micrel's contractual relationships and customer loyalty related to its distributor and end-customer relationships, and the fair values of the customer-related intangibles were determined based on Micrel's projected revenues. An analysis of expected attrition and revenue growth for existing customers was prepared from Micrel's historical customer information. Customer relationships are being amortized in a manner consistent with the estimated cash flows associated with the existing customers and anticipated retention rates. Backlog relates to the value of orders not yet shipped by Micrel at the acquisition date, and the preliminary fair values were based on the estimated profit associated with those orders. Backlog related assets are being recognized commensurate with recognition of the revenue for the orders on which the backlog intangible assets were determined. Amortization expense associated with acquired intangible assets is not deductible for tax purposes. Thus, approximately $ 99.7 million was established as a net deferred tax liability for the future amortization of the intangible assets offset by $ 11.4 million of net deferred tax assets. The amount of Micrel net sales included in the Company's condensed consolidated statements of income for the three and nine months ended December 31, 2015 was approximately $ 45.8 million and $ 67.3 million , respectively. The operations of Micrel were fully integrated into the Company's operations as of November 1, 2015 and as such, cost of sales and operating expenses were no longer segregated in the three or nine months ended December 31, 2015 . The following unaudited pro-forma consolidated results of operations for the three and nine months ended December 31, 2015 and 2014 assume the Micrel acquisition occurred as of April 1, 2014. The pro-forma adjustments are mainly comprised of acquired inventory fair value costs and amortization of purchased intangible assets. The pro-forma results of operations are presented for informational purposes only and are not indicative of the results of operations that would have been achieved if the acquisition had taken place on April 1, 2014 or of results that may occur in the future (amounts in thousands except per share data): Three Months Ended Nine Months Ended December 31, December 31, 2015 2014 2015 2014 Net sales $ 552,013 $ 586,628 $ 1,715,079 $ 1,771,565 Net income 80,236 70,041 282,273 195,428 Basic earnings per share $ 0.39 $ 0.35 $ 1.39 $ 0.97 Diluted earnings per share $ 0.37 $ 0.31 $ 1.30 $ 0.87 Acquisition of ISSC On July 17, 2014, the Company acquired an 83.5% interest in Taiwan based ISSC, a leading provider of low power Bluetooth and advanced wireless solutions for the Internet of Things (IoT) market. The Company acquired the 83.5% ownership interest through a tender offer process. Since the completion of the tender offer, the Company continued to acquire additional shares of ISSC, and as of June 30, 2015, the Company had completed the acquisition of 100% of the outstanding shares of ISSC. The acquisition was accounted for under the acquisition method of accounting.

Segment Information | Segment Information The Company's reportable segments are semiconductor products and technology licensing. The Company does not allocate operating expenses, interest income, interest expense, other income or expense, or provision for or benefit from income taxes to these segments for internal reporting purposes, as the Company does not believe that allocating these expenses is beneficial in evaluating segment performance. Additionally, the Company does not allocate assets to segments for internal reporting purposes as it does not manage its segments by such metrics.

Fair Value, Assets, Liabilities and Stockholders' Equity Measured on Recurring Basis [Abstract] | |
Fair Value Measurements | Fair Value Measurements Accounting rules for fair value clarify that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the Company utilizes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1- Observable inputs such as quoted prices in active markets; Level 2- Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and Level 3- Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Marketable Debt Instruments Marketable debt instruments include instruments such as corporate bonds and debt, government agency bonds, bank deposits, municipal bonds, and money market mutual funds. When the Company uses observable market prices for identical securities that are traded in less active markets, the Company classifies its marketable debt instruments as Level 2. When observable market prices for identical securities are not available, the Company prices its marketable debt instruments using non-binding market consensus prices that are corroborated with observable market data; quoted market prices for similar instruments; or pricing models, such as a discounted cash flow model, with all significant inputs derived from or corroborated with observable market data. Non-binding market consensus prices are based on the proprietary valuation models of pricing providers or brokers. These valuation models incorporate a number of inputs, including non-binding and binding broker quotes; observable market prices for identical or similar securities; and the internal assumptions of pricing providers or brokers that use observable market inputs and, to a lesser degree, unobservable market inputs. The Company corroborates non-binding market consensus prices with observable market data using statistical models when observable market data exists. The discounted cash flow model uses observable market inputs, such as LIBOR-based yield curves, currency spot and forward rates, and credit ratings. Derivatives The Company's derivative assets include interest rate swaps that are classified as Level 2 as the Company uses inputs other than quoted prices that are observable for the assets. The Level 2 derivative assets are primarily valued using standard calculations and models that use readily observable market data as their basis. Assets Measured at Fair Value on a Recurring Basis Assets measured at fair value on a recurring basis at December 31, 2015 are as follows (amounts in thousands): Quoted Prices in Active Markets for Identical Instruments (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Balance Assets Cash and cash equivalents: Money market mutual funds $ 29,971 $ — $ — $ 29,971 Deposit accounts — 301,480 — 301,480 Short-term investments: Marketable equity securities 3,022 — — 3,022 Corporate bonds and debt — 481,488 — 481,488 Government agency bonds — 187,319 — 187,319 Municipal bonds — 4,620 — 4,620 Long-term investments: Corporate bonds and debt — 744,173 — 744,173 Government agency bonds — 599,896 — 599,896 Municipal bonds — 36,095 — 36,095 Auction rate securities — — 9,825 9,825 Derivative assets — 4,693 — 4,693 Total assets measured at fair value $ 32,993 $ 2,359,764 $ 9,825 $ 2,402,582 Assets measured at fair value on a recurring basis at March 31, 2015 are as follows (amounts in thousands): Quoted Prices in Active Markets for Identical Instruments (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Balance Assets Cash and cash equivalents: Money market mutual funds $ 279,833 $ — $ — $ 279,833 Deposit accounts — 327,982 — 327,982 Short-term investments: Marketable equity securities 13,166 — — 13,166 Corporate bonds and debt — 756,664 — 756,664 Time deposits (1) — 506 — 506 Government agency bonds — 549,737 — 549,737 Municipal bonds — 30,981 — 30,981 Long-term investments: Corporate bonds and debt — 164,075 6,190 170,265 Government agency bonds — 192,519 — 192,519 Municipal bonds — 10,717 — 10,717 Auction rate securities — — 9,825 9,825 Derivative assets — 8,928 — 8,928 Total assets measured at fair value $ 292,999 $ 2,042,109 $ 16,015 $ 2,351,123 (1) Time deposits in various financial institutions with maturities greater than three months that will mature within one year. There were no transfers between Level 1 and Level 2 during the three and nine -month periods ended December 31, 2015 or the year ended March 31, 2015 . At December 31, 2015 and at March 31, 2015 , the Company's ARS for which auctions have been unsuccessful are made up of securities related to the insurance industry valued at $ 9.8 million with a par value of $ 22.4 million . The Company estimated the fair value of its ARS, which are classified as Level 3 securities, based on the following: (i) the underlying structure of each security; (ii) the present value of future principal and interest payments discounted at rates considered to reflect current market conditions; (iii) consideration of the probabilities of default, auction failure, or repurchase at par for each period; and (iv) estimates of the recovery rates in the event of default for each security. The significant unobservable inputs used in the fair value measurement of the ARS as of December 31, 2015 were estimated risk free discount rates, liquidity risk premium, and the liquidity horizon. The risk free discount rate applied to these securities was 2% to 2.5% adjusted for the liquidity risk premium which ranged from 9.1% to 29.5% . The anticipated liquidity horizon ranged from 7 to 10 years. A significant increase in the liquidity premium, discount rate or liquidity horizon, in isolation, would lead to a significantly lower fair value measurement. Each quarter, the Company investigates material changes in the fair value measurements of its ARS. The following table presents a reconciliation for all assets measured at fair value on a recurring basis, excluding accrued interest components, using significant unobservable inputs (Level 3) for the nine months ended December 31, 2015 (amounts in thousands): Nine months ended December 31, 2015 Auction Rate Securities Corporate Debt Total Losses Balance at March 31, 2015 $ 9,825 $ 6,190 $ — Total gains (losses) (realized): Included in earnings — (3,995 ) (3,995 ) Transfers out of Level 3 — (2,195 ) — Balance at December 31, 2015 $ 9,825 $ — $ (3,995 ) Transfers into or out of Level 3 are made if the inputs used in the financial models measuring the fair values of the assets and liabilities became unobservable or observable, respectively, in the current marketplace. During the three-months ended December 31, 2015, the Company transferred $ 2.2 million of corporate debt assets out of Level 3 as the inputs used to value these assets became observable in the current marketplace and are classified as Level 1 as of December 31, 2015. This transfer was effective on October 26, 2015. Gains and losses recognized in earnings are credited or charged to Other Income (Expense) on the Consolidated Statements of Income. Assets Measured and Recorded at Fair Value on a Non-Recurring Basis The Company's non-marketable equity, cost method investments, and non-financial assets, such as intangible assets, assets held for sale and property, plant and equipment, are recorded at fair value on a non-recurring basis. These assets are subject to fair value adjustments in certain circumstances, for example, when there is evidence of impairment. The Company's non-marketable and cost method investments are monitored on a quarterly basis for impairment charges. The fair values of these investments have been determined as Level 3 fair value measurements because the valuations use unobservable inputs that require management's judgment due to the absence of quoted market prices. There were no impairment charges recognized on these investments during each of the three and nine -month periods ended December 31, 2015 and December 31, 2014 . These investments are included in other assets on the condensed consolidated balance sheet. The fair value measurements related to the Company's non-financial assets, such as intangible assets, assets held for sale and property, plant and equipment are based on available market prices at the measurement date based on transactions of similar assets and third-party independent appraisals, less costs to sell where appropriate. The Company classifies these measurements as Level 2. |

Fair Value Disclosures [Abstract] | |
Fair Value of Financial Instruments | Fair Value of Financial Instruments The carrying amount of cash equivalents approximates fair value because their maturity is less than three months. Management believes the carrying amount of the equity and cost-method investments materially approximated fair value at December 31, 2015 based upon unobservable inputs. The fair values of these investments have been determined as Level 3 fair value measurements. The fair values of the Company's line of credit borrowings are estimated using discounted cash flow analyses, based on the Company's current incremental borrowing rates for similar types of borrowing arrangements and approximate carrying value. Based on the borrowing rates currently available to the Company for bank loans with similar terms and average maturities, the fair value of the Company's line of credit borrowings at December 31, 2015 approximated book value and are considered Level 2 in the fair value hierarchy described in Note 7. The carrying amount of accounts receivable, accounts payable and accrued liabilities approximates fair value due to the short-term maturity of the amounts and are considered Level 2 in the fair value hierarchy. Fair Value of Subordinated Convertible Debentures The Company measures the fair value of its senior and junior subordinated convertible debentures for disclosure purposes. These fair values are based on observable market prices for these debentures, which are traded in less active markets and are therefore classified as a Level 2 fair value measurement, and exclude the impacts of derivative activity. The carrying amounts and fair values of the Company’s senior and junior subordinated convertible debentures as of December 31, 2015 and March 31, 2015 are as follows (amounts in thousands): December 31, 2015 March 31, 2015 Carrying Amount Fair Value Carrying Amount Fair Value 1.625% Senior Subordinated Convertible Debentures $ 1,203,048 $ 1,733,004 $ 1,174,036 $ 1,787,531 2.125% Junior Subordinated Convertible Debentures $ 194,974 $ 1,081,633 $ 190,870 $ 1,124,125 |

Income Taxes | Income Taxes The provision for income taxes reflects tax on foreign earnings and federal and state tax on U.S. earnings. The Company had an effective tax rate benefit of 14.7% for the nine -month period ended December 31, 2015 and an effective tax rate of 6.0% for the nine -month period ended December 31, 2014 . The Company's effective tax rate for the nine -month period ended December 31, 2015 is lower compared to the prior year primarily due to the favorable tax impact from the integration of previously acquired intangible assets. The Company's effective tax rate is lower than statutory rates in the U.S. due primarily to its mix of earnings in foreign jurisdictions with lower tax rates. In December 2015, legislation was enacted which retroactively extends the research and experimentation tax credit on a permanent basis. As a result of the law change, the Company recorded a one-time tax benefit of $ 2.7 million in the three month period ended December 31, 2015, related to research activities incurred during fiscal year 2015. Likewise, the ongoing benefit from this credit is reflected in the Company's effective tax rate beginning in the three month period ended December 31, 2015. At December 31, 2015 , the Company had $ 257.6 million of unrecognized tax benefits. Unrecognized tax benefits increased by $ 58.7 million compared to March 31, 2015 . The current year increase is composed of $ 18.8 million related to acquisitions, $ 38.6 million related to ongoing accruals and releases, and $ 1.1 million related to deficiency interest on the positions. The majority of the increase in the uncertain tax position does not result in a change in the Company's effective tax rate for the current year. The Company files U.S. federal, U.S. state, and foreign income tax returns. For U.S. federal, and in general for U.S. state tax returns, the fiscal 2011 and later tax years remain open for examination by tax authorities. The U.S. Internal Revenue Service (IRS) is currently auditing Microchip's 2011 and 2012 tax years. For foreign tax returns, the Company is generally no longer subject to income tax examinations for years prior to fiscal 2007. The Company recognizes liabilities for anticipated tax audit issues in the U.S. and other domestic and international tax jurisdictions based on its estimate of whether, and the extent to which, additional tax payments are more likely than not. The Company believes that it has appropriate support for the income tax positions taken and to be taken on its tax returns and that its accruals for tax liabilities are adequate for all open years based on an assessment of many factors including past experience and interpretations of tax laws applied to the facts of each matter. The Company believes it maintains appropriate reserves to offset any potential income tax liabilities that may arise upon final resolution of matters for open tax years. If such reserve amounts ultimately prove to be unnecessary, the resulting reversal of such reserves would result in tax benefits being recorded in the period the reserves are no longer deemed necessary. If such amounts prove to be less than an ultimate assessment, a future charge to expense would be recorded in the period in which the assessment is determined. Although the timing of the resolution and/or closure of audits is highly uncertain, the Company does not believe it is reasonably possible that the unrecognized tax benefits would materially change in the next 12 months. |

Senior subordinated convertible debentures | 1.625% Senior Subordinated Convertible Debentures In February 2015, the Company issued $ 1,725.0 million principal amount of 1.625% senior subordinated convertible debentures due February 15, 2025 . The debentures are subordinated to the Company's senior debt, including amounts borrowed under its amended credit facility, but are senior to the Company's outstanding 2.125% junior subordinated convertible debentures. The debentures are convertible, subject to certain conditions, into cash, shares of the Company's common stock or a combination thereof, at the Company's election, at an initial base conversion rate of 14.5654 shares of common stock per $ 1,000 principal amount of debentures, representing an initial base conversion price of approximately $ 68.66 per share of common stock. As a result of cash dividends paid since the issuance of the debentures, the conversion rate has been adjusted to 15.0122 shares of common stock per $ 1,000 of principal amount of debentures, representing a base conversion price of approximately $ 66.61 per share of common stock. In addition, if at the time of conversion the applicable price of the Company's common stock exceeds the base conversion price, the conversion rate will be increased by up to an additional 7.2827 shares of common stock per $ 1,000 principal amount of debentures, as determined pursuant to a specified formula. As a result of cash dividends paid since the issuance of the debentures, the maximum number of additional shares that may be issued if the price of the Company's common stock exceeds the base conversion price has been adjusted to 7.5061 shares of common stock per $ 1,000 principal amount of debentures. However, in no event will the conversion rate exceed 20.3915 (adjusted to 21.0170 as a result of cash dividends paid since the issuance of the debentures) shares of common stock per $ 1,000 principal amount of debentures. The Company received net proceeds of approximately $ 1,694.7 million from the issuance of its senior subordinated convertible debentures after deduction of issuance costs of approximately $ 30.3 million . The $ 30.3 million in issuance costs was split between a debt component of $ 20.4 million and an equity component of $ 9.9 million . The $ 20.4 million in debt issuance costs is recorded in other assets and is being amortized using the effective interest method over the term of the debentures. Prior to the close of business on the business day immediately preceding November 15, 2024, the debentures will be convertible at the option of the debenture holders only upon the satisfaction of specified conditions and during certain periods. Thereafter until close of business on the second scheduled trading day immediately preceding February 15, 2025, the debentures will be convertible at the option of the debenture holders at any time regardless of these conditions. Accrued and unpaid interest will be considered fully paid upon settlement of shares. As the debentures can be settled in cash upon conversion, for accounting purposes, the debentures were bifurcated into a liability component and an equity component, which are both initially recorded at fair value. The carrying value of the equity component at December 31, 2015 and March 31, 2015 was $ 564.9 million . The estimated fair value of the liability component of the debentures at the issuance date was $1,160.1 million resulting in a debt discount of $ 564.9 million . The unamortized debt discount was $ 527.4 million at December 31, 2015 and $ 559.3 million at March 31, 2015 . The remaining period over which the unamortized debt discount will be recognized as non-cash interest expense is 9.12 years . In the three and nine months ended December 31, 2015 , the Company recognized $ 10.8 million and $ 31.9 million , respectively, in non-cash interest expense related to the amortization of the debt discount. The Company recognized $ 7.0 million and $ 21.0 million of interest expense related to the 1.625% coupon on the debentures in the three and nine months ended December 31, 2015 , respectively. The effective interest rate of the debentures is 6.1% . |

Junior subordinated convertible debentures | 2.125% Junior Subordinated Convertible Debentures The Company's $ 575.0 million principal amount of 2.125% junior subordinated convertible debentures due December 15, 2037 , are subordinated in right of payment to any future senior debt of the Company (including the Company's senior subordinated convertible debentures) and are effectively subordinated in right of payment to the liabilities of the Company's subsidiaries. The debentures are convertible, subject to certain conditions, into cash, shares of the Company's common stock or a combination thereof, at the Company's election, at an initial conversion rate of 29.2783 shares of common stock per $ 1,000 principal amount of debentures, representing an initial conversion price of approximately $ 34.16 per share of common stock. As of December 31, 2015 , the holders of the debentures had the right to convert their debentures between January 1, 2016 and March 31, 2016 because for at least 20 trading days during the 30 consecutive trading day period ending on December 31, 2015 , the Company's common stock had a last reported sale price greater than 130% of the conversion price. As of December 31, 2015 , a holder could realize more economic value by selling its debentures in the over the counter market than from converting its debentures. As a result of cash dividends paid since the issuance of the debentures, the conversion rate has been adjusted to 40.7888 shares of common stock per $ 1,000 of principal amount of debentures, representing a conversion price of approximately $ 24.52 per share of common stock. The if-converted value of the debentures exceed the principal amount by $ 516.5 million at December 31, 2015 . The debentures include a contingent interest mechanism that begins in December 2017. The terms of the contingent interest include a 0.25% interest rate if the debentures are trading at less than $400 and 0.5% if the debentures are trading at greater than $1,500 . Based on the current trading price of the debentures, the contingent interest rate in calendar year 2017 would be 0.5% . As the debentures can be settled in cash upon conversion, for accounting purposes, the debentures were bifurcated into a liability component and an equity component, which are both initially recorded at fair value. The carrying value of the equity component at December 31, 2015 and at March 31, 2015 was $ 411.2 million . The estimated fair value of the liability component of the debentures at the issuance date was $163.8 million , resulting in a debt discount of $ 411.2 million . The unamortized debt discount was $ 379.7 million at December 31, 2015 and $ 383.7 million at March 31, 2015 . The remaining period over which the unamortized debt discount will be recognized as non-cash interest expense is 22 years. In the three and nine months ended December 31, 2015 , the Company recognized $ 1.4 million and $ 4.0 million , respectively, in non-cash interest expense related to the amortization of the debt discount. In the three and nine months ended December 31, 2014 , the Company recognized $ 2.5 million and $ 7.3 million , respectively, in non-cash interest expense related to the amortization of the debt discount. The Company recognized $ 3.1 million and $ 9.2 million of interest expense related to the 2.125% coupon on the debentures in the three and nine months ended December 31, 2015 , respectively, compared to $ 6.1 million and $ 18.3 million in the three and nine months ended December 31, 2014 , respectively. The Company acquired $ 575.0 million in aggregate principal amount of its 2.125% junior subordinated convertible debentures in the March 2015 quarter which is the primary reason for the reductions of interest expense in the three and nine months ended December 31, 2015 compared to the prior year periods. The effective interest rate of the debentures is 9.1% . |

Line of Credit Facility [Abstract] | |
Credit Facility | Credit Facility In February 2015, the Company amended its existing $2.0 billion credit agreement by increasing the revolving credit facility to $2.555 billion and removing the term loan portion of the agreement. The new credit agreement includes two tranches. One tranche consists of bank commitments through February 2020 and another tranche consists of bank commitments through June 2018, the maturity date of the original credit agreement. The Company's increase option was also adjusted to $300 million . The credit agreement provides for a $ 125 million foreign currency sublimit, a $ 25 million letter of credit sublimit and a $25 million swingline loan sublimit. The amended credit agreement was accounted for as a modification and as such any remaining unamortized deferred costs associated with the prior credit agreement was associated with the new credit agreement since the borrowing capacity was increased. At December 31, 2015 , $ 1,008.5 million of revolving credit facility borrowings were outstanding under the credit agreement compared to $ 462.0 million at March 31, 2015 . In December 2015, the Company secured additional revolving credit commitments of $ 219 million from various banks in the February 2020 tranche under the increase option of the credit agreement, bringing its revolving credit facility to $ 2.774 billion at December 31, 2015. The remaining increase option was $ 30.4 million as of December 31, 2015. In December 2015, the Company amended the Maximum Total Leverage Ratio in Section 6.11 of its existing credit agreement to allow the Total Leverage Ratio to be temporarily increased to 5.00 to 1.00 for a period of four consecutive quarters in conjunction with a Permitted Acquisition occurring during the first of the four quarters. The Total Leverage Ratio then decreases to 4.75 to 1.00 for three consecutive quarters, finally returning to the stated 4.50 to 1.00 Total Leverage Ratio of the credit agreement after a period of seven consecutive fiscal periods. The Company can elect to use this special feature, also referred to as an Adjusted Covenant Period, no more than two times during the term of the credit agreement and also can terminate an Adjusted Covenant Period earlier than the seven consecutive quarters allowed. The loans under the credit agreement bear interest, at the Company's option, at the base rate plus a spread of 0.25% to 1.25% or an adjusted LIBOR rate (based on one, two, three, or six-month interest periods) plus a spread of 1.25% to 2.25% , in each case with such spread being determined based on the consolidated leverage ratio for the preceding four fiscal quarters (in the case of the 2018 tranche revolving loans) or the consolidated senior leverage ratio (in the case of the 2020 tranche revolving loans). The base rate means the highest of JPMorgan Chase Bank, N.A.'s prime rate, the federal funds rate plus a margin equal to 0.50% and the adjusted LIBOR rate for a 1-month interest period plus a margin equal to 1.00% . Swingline loans accrue interest at a per annum rate based on the base rate plus the applicable margin for base rate loans. Base rate loans may only be made in U.S. dollars. The Company is also obligated to pay other customary administration fees and letter of credit fees for a credit facility of this size and type. Interest is due and payable in arrears quarterly for loans bearing interest at the base rate and at the end of an interest period (or at each three-month interval in the case of loans with interest periods greater than three months) in the case of loans bearing interest at the adjusted LIBOR rate. Interest expense related to the credit agreement was approximately $ 6.4 million and $ 14.9 million in the three and nine months ended December 31, 2015 , respectively, and approximately $ 5.3 million and $ 15.4 million in the three and nine months ended December 31, 2014 , respectively. Principal, together with all accrued and unpaid interest, is due and payable on the respective tranche maturity date, which is June 27, 2018 and February 4, 2020. The weighted average interest rate on short-term borrowings outstanding at December 31, 2015 related to the credit agreement was 2.17% . The Company also pays a quarterly commitment fee on the available but unused portion of its line of credit which is calculated on the average daily available balance during the period. The Company may prepay the loans and terminate the commitments, in whole or in part, at any time without premium or penalty, subject to certain conditions including minimum amounts in the case of commitment reductions and reimbursement of certain costs in the case of prepayments of LIBOR loans. The Company's obligations under the credit agreement are guaranteed by certain of its subsidiaries meeting materiality thresholds set forth in the credit agreement. To secure the Company's obligations under the credit agreement, the Company and its domestic subsidiaries will be required to pledge the equity securities of certain of their respective material subsidiaries, subject to certain exceptions and limitations. The credit agreement contains customary affirmative and negative covenants, including covenants that limit or restrict the Company and its subsidiaries' ability to, among other things, incur subsidiary indebtedness, grant liens, merge or consolidate, dispose of assets, make investments, make acquisitions, enter into certain transactions with affiliates, pay dividends or make distributions, repurchase stock, enter into restrictive agreements and enter into sale and leaseback transactions, in each case subject to customary exceptions for a credit facility of this size and type. The Company is also required to maintain compliance with consolidated senior and total leverage ratios and a consolidated interest coverage ratio. At December 31, 2015 , the Company was in compliance with these covenants. The credit agreement includes customary events of default that include, among other things, non-payment defaults, inaccuracy of representations and warranties, covenant defaults, cross default to material indebtedness, bankruptcy and insolvency defaults, material judgment defaults, ERISA defaults and a change of control default. The occurrence of an event of default could result in the acceleration of the obligations under the credit agreement. Under certain circumstances, a default interest rate will apply on all obligations during the existence of an event of default under the credit agreement at a per annum rate equal to 2.00% above the applicable interest rate for any overdue principal and 2.00% above the rate applicable for base rate loans for any other overdue amounts. |

Commitments and Contingencies Disclosure [Abstract] | |
Contingencies | Contingencies In the ordinary course of the Company's business, it is involved in a limited number of legal actions, both as plaintiff and defendant, and could incur uninsured liability in any one or more of them. The Company also periodically receives notifications from various third parties alleging infringement of patents, intellectual property rights or other matters. With respect to pending legal actions to which the Company is a party, although the outcomes of these actions are not generally determinable, the Company believes that the ultimate resolution of these matters will not have a material adverse effect on its financial position, cash flows or results of operations. Litigation relating to the semiconductor industry is not uncommon, and the Company is, and from time to time has been, subject to such litigation. No assurances can be given with respect to the extent or outcome of any such litigation in the future. The Company's technology license agreements generally include an indemnification clause that indemnifies the licensee against liability and damages (including legal defense costs) arising from any claims of patent, copyright, trademark or trade secret infringement by the Company's proprietary technology. The terms of these indemnification provisions approximate the terms of the outgoing technology license agreements, which are typically perpetual unless terminated by either party for breach. The possible amount of future payments the Company could be required to make based on agreements that specify indemnification limits, if such indemnifications were required on all of these agreements, is approximately $ 140 million . There are some licensing agreements in place that do not specify indemnification limits. The Company had not recorded any liabilities related to these indemnification obligations as of December 31, 2015 . |

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Derivative Instruments | Derivative Instruments Freestanding Derivative Forward Contracts Foreign Currency Exchange Rate Risk The Company has international operations and is thus subject to foreign currency rate fluctuations. To help manage the risk of changes in foreign currency rates, the Company periodically enters into derivative contracts comprised of foreign currency forward contracts to hedge its asset and liability foreign currency exposure and a portion of its foreign currency operating expenses. Approximately 99 % of the Company's sales are U.S. dollar denominated. To date, the exposure related to foreign exchange rate volatility has not been material to the Company's operating results. As of December 31, 2015 and March 31, 2015, the Company had no foreign currency forward contracts outstanding. The Company recognized an immaterial amount of net realized gains and losses on foreign currency forward contracts in each of the three and nine months ended December 31, 2015 and 2014. Gains and losses from changes in the fair value of these foreign currency forward contracts and foreign currency exchange rate fluctuations are credited or charged to Other Income (Expense) on the condensed consolidated statements of income. The Company does not apply hedge accounting to its foreign currency derivative instruments. Fair Value Hedges For derivative instruments that are designated and qualify as fair value hedges, the gain or loss on the derivatives as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in earnings. Interest rate derivative instruments designated as fair value hedges are designed to manage the exposure to interest rate movements and to reduce borrowing costs by converting fixed-rate debt into floating-rate debt. Under these agreements, the Company agrees to exchange, at specified intervals, the difference between the fixed and floating interest amounts calculated by reference to an agreed-upon notional principal amount. In March 2015, the Company entered into ten-year fixed-to-floating interest rate swap agreements designated as fair value hedges of the changes in fair value of a portion of the Company's fixed-rate 1.625% senior subordinated convertible debentures due to changes in the LIBOR swap rate, the designated benchmark interest rate.

Net income per common share | Net Income Per Common Share Attributable to Microchip Technology Stockholders The following table sets forth the computation of basic and diluted net income per common share attributable to Microchip Technology stockholders (in thousands, except per share amounts): Three Months Ended Nine Months Ended December 31, December 31, 2015 2014 2015 2014 Net income attributable to Microchip Technology $ 61,211 $ 86,057 $ 256,777 $ 269,607 Weighted average common shares outstanding 203,294 201,203 203,267 200,673 Dilutive effect of stock options and RSUs 3,593 3,396 3,350 3,652 Dilutive effect of 2037 junior subordinated convertible debentures 11,088 18,888 10,663 20,108 Weighted average common and potential common shares outstanding 217,975 223,487 217,280 224,433 Basic net income per common share attributable to Microchip Technology stockholders $ 0.30 $ 0.43 $ 1.26 $ 1.34 Diluted net income per common share attributable to Microchip Technology stockholders $ 0.28 $ 0.39 $ 1.18 $ 1.20 The Company computed basic earnings per common share attributable to its stockholders using net income available to common stockholders and the weighted average number of common shares outstanding during the period. The Company computed diluted earnings per common share attributable to its stockholders using net income available to stockholders and the weighted average number of common shares outstanding plus potentially dilutive common shares outstanding during the period. Potentially dilutive common shares from employee equity incentive plans are determined by applying the treasury stock method to the assumed exercise of outstanding stock options and the assumed vesting of outstanding RSUs. Diluted net income per common share attributable to stockholders for the three and nine months ended December 31, 2015 includes 11,088,239 shares and 10,663,468 shares, respectively, issuable upon the exchange of the Company's 2.125% junior subordinated convertible debentures due December 15, 2037 (see Note 17). Diluted net income per common share attributable to stockholders for the three and nine months ended December 31, 2014 includes 18,888,013 shares and 20,107,818 shares, respectively, issuable upon the exchange of the Company's 2.125% junior subordinated convertible debentures due December 15, 2037. The debentures have no impact on diluted net income per common share unless the average price of the Company's common stock exceeds the conversion price because the principal amount of the debentures will be settled in cash upon conversion. Prior to conversion, the Company will include, in the diluted net income per common share calculation, the effect of the additional shares that may be issued when the Company's common stock price exceeds the conversion price using the treasury stock method. The weighted average conversion price per share used in calculating the dilutive effect of the convertible debt for the three and nine -month periods ended December 31, 2015 was $24.62 and $24.83 , respectively. The weighted average conversion price per share used in calculating the dilutive effect of the convertible debt for the three and nine -month periods ended December 31, 2014 was $25.39 and $25.57 , respectively There were no shares issuable upon the exchange of the Company's 1.625% senior subordinated convertible debentures due February 15, 2025 (see Note 16). The debentures have no impact on diluted net income per common share unless the average price of the Company's common stock exceeds the conversion price because the principal amount of the debentures will be settled in cash upon conversion. Prior to conversion, the Company will include, in the diluted net income per common share calculation, the effect of the additional shares that may be issued when the Company's common stock price exceeds the conversion price using the treasury stock method. The weighted average conversion price per share used in calculating the dilutive effect of the convertible debt for the three and nine -month periods ended December 31, 2015 was $66.89 and $67.46 , respectively. Weighted average common shares exclude the effect of option shares which are not dilutive. For the three and nine months ended December 31, 2015 , the number of option shares that were antidilutive was 292,327 and 319,981 , respectively. For each of the three and nine months ended December 31, 2014 , the number of option shares that were antidilutive was 46,959 . |
