Intersil Corporation is an American company that specializes in the design, development and manufacturing of high-performance analog semiconductors for four high-growth markets — Communications, Computing, High End Consumer and Industrial.
Company history 
Intersil was founded in 1967 by Jean Hoerni to produce digital watches. 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 was reborn with the largest IPO in American semiconductor industry history. 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 ICM8038 waveform generator.
Intersil has focused on growth and opportunities in the “pure-play”, high-performance analog semiconductor market.
Some of the many end applications in which Intersil analog integrated circuits can be found include desktop and notebook PCs, cell phones, portable media players and other handheld devices, video distribution systems, video displays, medical equipment, military and space electronics, and industrial systems. Intersil has 47 product families whose products include amplifiers, analog front ends, communication interfaces, data converters, digital potentiometers, display solutions, DSL solutions, optical storage products, power management products, power sequencers, real time clocks, battery management ICs, switches/MUXes, VoIP products and harsh environment ICs for mining, military, space and radiation hardened applications.
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 is currently maintained by Conexant. Intersil is the present manufacturer of the RCA (CDP)1802 microprocessor (aka RCA COSMAC), a CPU traditionally much used in space applications.
