Intersil

The original Intersil, Inc. was founded in 1967 by the Swiss physicist Jean Hoerni to develop digital watch Integrated Circuits (ICs).{{disputed inline|date=December 2018}} The European subsidiary Eurosil was originally partially funded by SSIH, a Swiss watch company. Later-on, Intersil had a development contract with the Japanese company Daini Seikosha and became supplier of low-voltage CMOS watch ICs for Seiko.Lucien Trueb: Die Elektrifizierung der Armbanduhr. Ebner, Ulm 2011, {{ISBN|978-3-87188-236-4}} When microprocessors emerged to the market in the 1970s, Intersil participated with its 12-bit IM6100, which was the first microprocessor produced in CMOS technology and emulated the PDP-8 instruction set.

In 1988, Intersil was taken over by Harris Semiconductor, which had offered the IM6100 as second source. Harris combined these activities with the semiconductor divisions of Radiation Incorporated, General Electric and RCA they had taken over before. In 1999 Harris spun off its entire semiconductor division and Intersil Corporation was created {{Cite web | url=http://harris.com/view_pressrelease.asp?pr_id=483 |title = Press Releases}} with the largest IPO in American semiconductor industry history.[http://intersil.eefocus.com/article/09-09/9061301100901gxDG.html Intersil庆祝成立10周年] {{Webarchive|url=https://web.archive.org/web/20110307195020/http://intersil.eefocus.com/article/09-09/9061301100901gxDG.html |date=2011-03-07 }} {{in lang|zh}} The second Intersil Corporation is a different company from the original Intersil, Inc.

Next to digital circuits like microprocessors and memories like the 1k-bit CMOS RAM IM6508 and CMOS EPROMS IM6604/IM6654 Intersil designed famous analogue ICs like the ICL8038 waveform generator. A creation of Intersil (as Harris Semiconductor) is the PRISM line of Wi-Fi hardware: that group of products was sold to GlobespanVirata in 2003, and maintained by Conexant. Intersil is the manufacturer of the RCA (CDP)1802 microprocessor (also known as RCA COSMAC),{{Cite web | url=http://www.cpushack.com/2010/09/04/from-video-games-to-deep-space-the-rca-1802-cosmac/ |title = From Video Games to Deep Space – the RCA 1802 COSMAC | the CPU Shack Museum|date = 5 September 2010}} a CPU traditionally used in space applications.

In the 2000s, Intersil established market leadership in Vcore{{Clarify|date=October 2016}} power management for PCs, switching and buck boost regulators for industrial and consumer power systems, and radiation hardened analog and power ICs for military and commercial applications.

The company, under CEO Dave Bell,{{Cite news | url=http://www.marketwatch.com/story/intersil-ceo-beyer-resigns-david-bell-named-as-new-ceo?dateid=39491.6787733681-921564050 |title = Intersil CEO Beyer resigns, David Bell named as new CEO| newspaper=Marketwatch | last1=Witkowski | first1=Wallace }} then began the expansion of a catalog analog business. The company also completed a series of acquisitions, two of which are still part of the portfolio, Zilker Labs{{Cite web | url=http://powerelectronics.com/content/intersil-acquires-zilker-labs |title = Intersil Acquires Zilker Labs|date = January 2009}} digital power devices and Techwell{{Cite web | url=http://www.electronicsweekly.com/news/business/intersil-ceo-holds-steady-on-analogue-strategy-2008-10/ | title=Intersil CEO holds steady on analogue strategy| date=2008-10-08}} automotive and security and surveillance products.{{Cite web | url=https://www.bloomberg.com/apps/news?pid=newsarchive&sid=ay_ogRXA2ufM |title = Bloomberg Politics - Bloomberg|website = Bloomberg News| date=27 April 2024 }} In May 2002, Intersil Corp. acquired Elantec Semiconductor. In March 2004,  Intersil Corp. acquired analog chipmaker Xicor Inc. for about $529 million.

In 2012, with revenue in decline, the company's board of directors removed Dave Bell{{cite web |url=http://intersil.presscentre.com/Press-releases/Intersil-Announces-Resignation-of-Dave-Bell-as-President-CEO-9ef.aspx |title=Intersil - Press releases - Intersil Announces Resignation of Dave Bell as President & CEO |access-date=2014-03-14 |url-status=dead |archive-url=https://archive.today/20140314191309/http://intersil.presscentre.com/Press-releases/Intersil-Announces-Resignation-of-Dave-Bell-as-President-CEO-9ef.aspx |archive-date=2014-03-14 }} and began a search for a new CEO. In March 2013, the board appointed Necip Sayiner, the architect of Silicon Labs' turnaround, as CEO. Sayiner concentrated the company's efforts on power management and select target markets. The company was able to return to profitabilityhttp://intersil.presscentre.com/imagelibrary/downloadmedia.ashx?MediaDetailsID=121&SizeId=-1{{dead link|date=November 2017 |bot=InternetArchiveBot |fix-attempted=yes }} in 2013 and in early 2014 re-launched as a power management company, with products to improve power efficiency, extend battery life and reduce size.
