'''Intersil''' is an American [[semiconductor]] company headquartered in [[Milpitas, California]]. It was formed in 1967 by [[Jean Hoerni]], one of the original [[traitorous eight]]. The company initially worked primarily on [[Analog device|analog]] electronics, but later moved into [[CMOS]] designs and produced some of the earliest [[Quartz clock|electronic watch]]es. They leveraged th produced a series of CMOS devices, including the [[Intersil 6100]], a single-chip implementation of the [[PDP-8]] computer.

Intersil was purchased by [[Harris Corporation]] in 1988, one of Intersil's major [[second source]] providers. The Intersil brand was later abandoned and became Harris Semiconductor. In August 1999, Harris sold off its semiconductor division to a newly-formed Intersil Corp. This was purchased by [[Renesas Electronics|Renesas]] in February 2017.<ref>{{Cite press release|title=Renesas and Intersil Announce Final Regulatory Approval for Renesas' Acquisition of Intersil|date=February 22, 2017|publisher=Renesas Electronics|url=https://www.renesas.com/en-us/about/press-center/news/2017/news20170222.html}}{{Self-published source|date=February 2017}}</ref> Today, it concentrates on [[power management]] IC, with specialized capability in power management and precision [[Analogue electronics|analog technology]] for applications in industrial, infrastructure, mobile, automotive and aerospace.

==Company history==
The original Intersil, Inc. was founded in 1967 by the Swiss physicist [[Jean Hoerni]] to develop analog circuits based on [[Bipolar electricity transmission|bipolar]] and [[field effect transistor]]s, including [[operational amplifier]]s.{{sfn|Laws|2019|p=17}} This led to work on many small [[integrated circuit]] designs, including an analog comparator for [[NASA]], and later a shutter-speed calculator for [[Canon Inc.]]{{sfn|Laws|2019|pp=18-19}} This led to considerable work with and for [[Analog Devices]] (AD), and eventually AD put one engineer in Intersil's offices as a liaison.{{sfn|Laws|2019|p=20}}

Hoerni arranged a deal with [[Omega SA]] to develop a custom digital watch ICs.{{sfn|Laws|2019|p=20}} To meet the power requirements of a battery-powered device, the company had to use [[CMOS]] technology, and were a pioneer in this field. This was carried out by a new division, Eurosil, partially funded by [[Société Suisse pour l'Industrie Horlogère|SSIH]], a Swiss watchmaking industry group. Later, Intersil had a development contract with the Japanese company [[Seikosha|Daini Seikosha]] and became supplier of watch ICs for [[Seiko]].<ref>Lucien Trueb: ''Die Elektrifizierung der Armbanduhr.'' Ebner, Ulm 2011, {{ISBN|978-3-87188-236-4}}</ref>

When [[microprocessor]]s emerged in the 1970s, Intersil participated with its [[12-bit]] [[Intersil 6100|IM6100]], which was the first microprocessor produced in CMOS technology. It emulated the [[PDP-8]] instruction set. Intersil was also the manufacturer of the [[RCA 1802|RCA (CDP)1802]] microprocessor (also known as RCA COSMAC),<ref>{{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}}</ref> a [[central processing unit|CPU]] traditionally used in space applications.

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 Corporation|RCA]] it had taken over before. In 1999 Harris spun off its entire semiconductor division and Intersil Corporation was created <ref>{{Cite web | url=http://harris.com/view_pressrelease.asp?pr_id=483 |title = Press Releases}}</ref> with the largest IPO in American semiconductor industry history.<ref>[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}}</ref> 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 [[8038 ic|ICL8038]] waveform generator. A creation of Intersil (as Harris Semiconductor) is the [[PRISM (chipset)|PRISM]] line of [[Wi-Fi]] hardware: that group of products was sold to [[GlobespanVirata]] in 2003, and maintained by [[Conexant]].

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,<ref>{{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 }}</ref> 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<ref>{{Cite web | url=http://powerelectronics.com/content/intersil-acquires-zilker-labs |title = Intersil Acquires Zilker Labs|date = January 2009}}</ref> digital power devices and Techwell<ref>{{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}}</ref> automotive and security and surveillance products.<ref>{{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 }}</ref> 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<ref name="intersil.presscentre.com">{{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 }}</ref> and began a search for a new CEO. In March 2013, the board appointed Necip Sayiner,<ref name="intersil.presscentre.com"/> 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 profitability<ref>http://intersil.presscentre.com/imagelibrary/downloadmedia.ashx?MediaDetailsID=121&SizeId=-1{{dead link|date=November 2017 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> 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.
