Intersil

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 electronics, but later moved into CMOS designs and produced some of the earliest electronic watches. They 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 in February 2017. Today, it concentrates on power management IC, with specialized capability in power management and precision analog technology for applications in industrial, infrastructure, mobile, automotive and aerospace.
