Accounting Policies [Abstract]	'
Basis of Presentation	'
	1. Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission, or the SEC, and U.S. generally accepted accounting principles, or U.S. GAAP. However, certain information or footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such SEC rules and regulations. In our opinion, the financial statements include all adjustments, which are of a normal and recurring nature, necessary for the fair presentation of the results of the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the operating results for the full fiscal year or any future period. These financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2013.
	The consolidated financial statements include our financial statements and those of our wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated upon consolidation.
	Our fiscal year is the 52- or 53-week period ending on the last Saturday in June. Our fiscal 2014 and 2013 are 52-week periods ending on June 28, 2014 and June 29, 2013, respectively. The quarterly fiscal periods presented in this report were 13-week periods for the three months ended September 28, 2013 and September 29, 2012. For ease of presentation, the accompanying consolidated financial statements have been shown as ending on calendar quarter end dates for all annual, interim, and quarterly financial statement captions, unless otherwise indicated.
	Use of Estimates
	The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, allowance for doubtful accounts, cost of revenue, inventories, loss on purchase commitments, product warranty, share-based compensation costs, provision for income taxes, deferred income tax asset valuation allowances, uncertain tax positions, tax contingencies, goodwill, intangible assets, investments, contingent consideration liability, and loss contingencies. We base our estimates on historical experience, applicable laws and regulations, and various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
	Recently Issued Accounting Pronouncements
	There are no new accounting pronouncements that are expected to have a material impact on our condensed consolidated financial statements.

Revenue Recognition	'
	2. Revenue Recognition
	We recognize revenue from product sales when there is persuasive evidence that an arrangement exists, delivery has occurred and title has transferred, the price is fixed or determinable, and collection is reasonably assured, which is generally upon shipment of the product. We accrue for estimated sales returns, incentives, and other allowances at the time we recognize revenue. Our products contain embedded firmware and software that allows for further differentiation and customer integration, which together with our ASIC chip, delivers the essential functionality of our products and, as such, software revenue recognition guidance is not applicable.

	3. Net Income Per Share
	The computation of basic and diluted net income per share was as follows (in thousands, except per share data):
		Three Months Ended
		September 30,
		2013		2012
	Numerator:
	Net income	$	34,939	$	6,053
	Denominator:
	Shares, basic		32,958		32,941
	Effect of dilutive share-based awards		2,062		1,073
	Shares, diluted		35,020		34,014
	Net income per share:
	Basic	$	1.06	$	0.18
	Diluted	$	1	$	0.18
	Our basic net income per share amounts for each period presented have been computed using the weighted average number of shares of common stock outstanding. Our diluted net income per share amounts for each period presented include the weighted average effect of potentially dilutive shares. We use the “treasury stock” method to determine the dilutive effect of our stock options, deferred stock units, or DSUs, market stock units, or MSUs, and convertible notes.
	Dilutive net income per share amounts do not include the weighted average effect of 503,115 and 3,990,394 share-based awards that were outstanding during the three months ended September 30, 2013 and 2012, respectively. These share-based awards were not included in the computation of diluted net income per share because their effect would have been antidilutive.

	Liabilities:
	Contingent consideration liability recorded for business combination	$	—	$	8,505	$	—	$	8,247
	In our condensed consolidated balance sheets as of September 30, 2013 and June 30, 2013, money market balances are included in cash and cash equivalents; auction rate securities, or ARS investments, are included in non-current investments. The contingent consideration liability recorded for a business combination is included in other liabilities; of which $8.3 million and $8.1 million is included in the non-current portion of other liabilities as of September 30, 2013 and June 30, 2013, respectively, and $196,000 has been included in other current liabilities as of both periods.
	Changes in fair value of our Level 3 financial assets as of September 30, 2013 were as follows (in thousands):
	Balance as of June 30, 2013	$	16,969
	Net unrealized gain		567
	Balance as of September 30, 2013	$	17,536
	Changes in fair value of our Level 3 contingent consideration liability as of September 30, 2013 were as follows (in thousands):
	Balance as of June 30, 2013	$	8,247
	Accretion and remeasurement		258
	Balance as of September 30, 2013	$	8,505
	In connection with the acquisition of Pacinian in June 2012, we entered into a contingent consideration arrangement, and subsequently paid $5.0 million of additional consideration to the former Pacinian stockholders upon customer acceptance of a ThinTouch product. As of September 30, 2013, we may owe up to $10.0 million of additional consideration to the former Pacinian stockholders based on sales of products utilizing ThinTouch technology through June 2016.
	There were no transfers in or out of our Level 1 or 3 assets or liabilities during the three months ended September 30, 2013.
	The fair values of our accounts receivable and accounts payable approximate their carrying values because of the short-term nature of those instruments. The fair value of our notes payable approximates their carrying value in all material respects. Intangible assets, property and equipment, and goodwill are measured at fair value on a non-recurring basis if impairment is indicated.

Auction_Rate_Securities

Auction Rate Securities	3 Months Ended

Text Block [Abstract]	'
Auction Rate Securities	'
	5. Auction Rate Securities
	Our ARS investments have failed to settle in auctions and are not liquid. In the event we need to access these funds prior to their maturity, we will not be able to do so without a loss of principal, unless redeemed by the issuers or a future auction on these investments is successful. During the three months ended September 30, 2013, none of our ARS investments were redeemed.
	As there are currently no active markets for our various failed ARS investments, we have estimated the fair value as of September 30, 2013 using a trinomial discounted cash flow analysis. The analysis considered, among others, the following factors:
		•		the collateral underlying the security investments;
		•		the creditworthiness of the counterparty;
		•		the timing of expected future cash flows;
		•		the probability of a successful auction in a future period;
		•		the underlying structure of each investment;
		•		the present value of future principal and interest payments discounted at rates considered to reflect current market conditions;
		•		a consideration of the probabilities of default, passing a future auction, or redemption at par for each period; and
		•		estimates of the recovery rates in the event of default for each investment.
	When possible, our failed ARS investments were compared to other observable market data or securities with similar characteristics. Our estimate of the fair value of our ARS investments could change materially from period to period based on future market conditions.
	Contractual maturities for our ARS investments are generally greater than five years, with fair value of $12.4 million maturing from calendar years 2015 to 2017, $3.1 million maturing from calendar years 2043 to 2045, and $2.0 million having no maturity date. Of our ARS investments, $5.5 million par value are investment grade, and the remaining $18.5 million par value are below investment grade.
	The various types of ARS investments we held as of September 30, 2013, including the original cost basis, other-than-temporary impairment included in retained earnings, new cost basis, unrealized gain/(loss), and fair value, consisted of the following (in thousands):
					Other-than-

	-1	Other-than-temporary impairment in retained earnings is partially offset by cumulative accretion of $415,000 on non-current investments. Accretion is reclassified from accumulated other comprehensive income and recorded in the condensed consolidated statements of income as non-cash interest income.

Accretion is reclassified from accumulated other comprehensive income and recorded in the condensed consolidated statements of income as non-cash interest income.
	The ARS investments in each of the above tables with unrealized losses have been in a continuous unrealized loss position for more than 12 months.
	We have accounted for all of our ARS investments as non-current as we are not able to reasonably determine when the ARS markets will recover or be restructured. Based on our ability to access our cash and cash equivalents, our expected operating cash flows, and our other sources of cash, we do not intend to sell the investments, and it is not more likely than not that we will be required to sell the investments before the recovery of the amortized cost basis. We will continue to monitor our ARS investments and evaluate our accounting for these investments quarterly.

	8. Product Warranties, Indemnifications, and Contingencies
	Product Warranties
	We generally warrant our products for a period of 12 months from the date of sale and estimate probable product warranty costs at the time we recognize revenue. Factors that affect our warranty liability include historical and anticipated rates of warranty claims, materials usage, rework, and delivery costs. However, we assess the adequacy of our warranty obligations each reporting period and adjust the accrued warranty liability on the basis of our estimates.
	Indemnifications
	In connection with certain third-party agreements we have executed in the past, we are obligated to indemnify the third party in connection with any technology infringement by us. We have also entered into indemnification agreements with our officers and directors. Maximum potential future payments cannot be estimated because these agreements do not have a maximum stated liability. However, historical costs related to these indemnification provisions have not been significant. We have not recorded any liability in our consolidated financial statements for such indemnification obligations.
	Contingencies
	We have in the past and may in the future receive notices from third parties that claim our products infringe their intellectual property rights. We cannot be certain that our technologies and products do not or will not infringe issued patents or other proprietary rights of third parties.
	Any infringement claims, with or without merit, could result in significant litigation costs and diversion of management and financial resources, including the payment of damages, which could have a material adverse effect on our business, financial condition, and results of operations.

	The aggregate intrinsic value was determined using the closing price of our common stock on September 27, 2013 of $43.52.
	Of the shares delivered, 42,094 shares valued at $1.7 million were withheld to meet statutory minimum tax withholding requirements.
	Market Stock Units
	Our Amended and Restated 2010 Incentive Compensation Plan provides for the grant of MSU awards, which are a type of DSU award, to our employees, consultants, and directors. An MSU is a promise to deliver shares of our common stock at a future date based on the achievement of market-based performance requirements in accordance with the terms of the MSU grant agreement. We began granting MSUs in November 2012.
	In November 2012, we granted MSUs to our executive officers, which were designed to vest in three tranches with the target quantity for each tranche equal to one-third of the total MSU grant. The first tranche vests based on a one-year performance period; the second tranche vests based on a two-year performance period; and the third tranche vests based on a three-year performance period. Performance is measured based on the achievement of a specified level of total stockholder return, or TSR, relative to the TSR of the Philadelphia Semiconductor Index, or SOX Index. The potential payout ranges from 0% to 200% of the grant target quantity and is adjusted on a two-to-one ratio based on our TSR performance relative to the SOX Index TSR performance using the following formula:
	(100% + ([Synaptics TSR - SOX Index TSR] x 2))
	Delivery of shares earned, if any, will take place on the dates provided in the applicable MSU grant agreement, assuming the grantee is still an employee, consultant, or director of our company at the end of the applicable performance period. On the delivery date, we withhold shares to cover statutory minimum tax withholding by delivering a net quantity of shares. Until delivery of shares, the grantee has no rights as a stockholder with respect to any shares underlying the MSU award.
	During the three months ended September 30, 2013, there were no MSUs granted and there were no shares under our MSU awards delivered or forfeited. We valued the MSUs using the Monte Carlo simulation model and amortize the compensation expense over the three-year performance and service period. The weighted average grant date fair value for the MSUs granted was $25.82. The unrecognized share-based compensation cost for MSUs granted was approximately $1.3 million as of September 30, 2013, which will be recognized over a weighted average period of approximately 1.0 years. As of September 30, 2013, the aggregate intrinsic value of the MSUs was $2.9 million (assuming a 100% payout factor), which was determined using the closing price of our common stock on September 27, 2013 of $43.52.

Income Taxes	'
	10. Income Taxes
	We account for income taxes under the asset and liability method. We consider the operating earnings of our foreign subsidiaries to be indefinitely invested outside the United States. Accordingly, no provision has been made for the federal, state, or foreign taxes that may result from future remittances of undistributed earnings of our foreign subsidiaries.
	The provision for income taxes of $12.7 million and $2.5 million for the three months ended September 30, 2013 and 2012, respectively, represented estimated federal, foreign, and state income taxes. The effective tax rate for the three months ended September 30, 2013 was 26.6% and diverged from the combined federal and state statutory rate primarily because of foreign income taxed at lower tax rates and the federal research credit, partially offset by foreign withholding taxes, and net unrecognized tax benefits associated with qualified stock options. The effective tax rate for the three months ended September 30, 2012 was 29.2% and diverged from the combined federal and state statutory rate primarily because of foreign income taxed at lower tax rates, partially offset by foreign withholding taxes, net unrecognized tax benefit associated with qualified stock options, and a slight increase in the liability for unrecognized tax benefits related to uncertain tax positions.
	Unrecognized Tax Benefits
	The total liability for gross unrecognized tax benefits increased $146,000 during the three months ended September 30, 2013 to $8.4 million from $8.2 million at June 30, 2013 and is included in other liabilities on our condensed consolidated balance sheets. All of this amount would affect the effective tax rate on income from continuing operations, if recognized. The balance of interest and penalties accrued related to unrecognized tax benefits as of September 30, 2013 was $918,000 and increased by $5,000 from June 30, 2013. We classify interest and penalties as components of income tax expense.
	In May 2011, we were notified by the Internal Revenue Service (Service) that our fiscal 2003 through 2006 and fiscal 2008 through 2010 would be subject to examination. The early periods were being audited in connection with a mandatory review of tax refunds in excess of $2.0 million when we carried back our fiscal 2008 net operating loss. In March 2013, we received the Revenue Agent’s Report resolving our examination with the Service and paid an assessment that had no material impact to our condensed consolidated financial statements. Our case is pending review by the Joint Committee of Taxation, which we anticipate to conclude in our fiscal 2014. Any prospective adjustments to our unrecognized tax benefits will be recorded as an increase or decrease to income tax expense and cause a corresponding change to our effective tax rate. Accordingly, our effective tax rate could fluctuate materially from period to period.
	On January 2, 2013, President Barack Obama signed into law The American Taxpayer Relief Act of 2013 (The Act). The Act extends the research credit for two years retroactively from January 1, 2012 through December 31, 2013. As such, we will only recognize six months of tax benefit in our current fiscal year.
	Our major tax jurisdictions are the United States, California, and Hong Kong SAR, and fiscal 2003 onward remain subject to examination by one or more of these jurisdictions.

	Our comprehensive income generally consists of net income plus the effect of unrealized gains and losses on our investments, primarily due to temporary changes in market value of certain of our ARS investments. In addition, we recognize the noncredit portion of other-than-temporary impairment on debt securities in other comprehensive income. We recognize foreign currency remeasurement adjustments and transaction gains and losses in our condensed consolidated statements of income as the U.S. dollar is the functional currency of our foreign entities.

	14. Subsequent Event
	On October 9, 2013, we signed a definitive agreement to acquire a privately held company, Validity Sensors, Inc., or Validity, a leading provider of biometric fingerprint authentication solutions for smartphones, tablets, and notebooks. The transaction has been approved by our board of directors and Validity’s board of directors and is subject to customary closing conditions. There are no financing contingencies related to the acquisition. The transaction is expected to close in the second quarter of fiscal 2014. With this acquisition we expect to gain access to the fast growing biometrics market, significantly expanding our market opportunity and underscoring our commitment to making smart devices easier to use. The acquisition is expected to be completed by acquiring all capital stock and other vested and unvested equity interests of Validity for an aggregate base purchase price of $92.5 million. In addition, we may become obligated to make earn-out consideration payments of up to an additional $162.5 million, which is based primarily on sales, during certain time periods, ending on March 31, 2016, of certain products embodying Validity fingerprint sensor technology. The earn-out consideration will generally be payable in cash, but there are certain conditions that require payout of a portion of the earn-out consideration, if any, in our common stock. Pursuant to the merger agreement we expect to create a merger sub wholly owned by us that will be merged with and into Validity, with Validity surviving as our wholly owned subsidiary, and as part of the same overall transaction, Validity will then merge with and into another merger sub wholly owned by us, with such other merger sub surviving such merger as our wholly owned subsidiary. Pursuant to the Merger, the Company incurred approximately $1.0 million in direct acquisition costs during the September quarter which were expensed as incurred.
	The acquisition will be accounted for using the purchase method of accounting in accordance with the business acquisition guidance. Under the purchase accounting method, the total estimated purchase consideration of the acquisition will be allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their relative fair values. The excess of the purchase consideration over the net tangible and identifiable intangible assets acquired and liabilities will be recorded as goodwill.

	Use of Estimates
	The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, allowance for doubtful accounts, cost of revenue, inventories, loss on purchase commitments, product warranty, share-based compensation costs, provision for income taxes, deferred income tax asset valuation allowances, uncertain tax positions, tax contingencies, goodwill, intangible assets, investments, contingent consideration liability, and loss contingencies. We base our estimates on historical experience, applicable laws and regulations, and various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
