Headquartered in Milpitas, California, Intersil had revenues of $757M for 2007. Its global operations include a staff of over 1,400 employees spread out among its 57 design, manufacturing, and sales locations.
Intersil has 47 product families. Leadership 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/MUX's, VoIP products and harsh environment ICs for mining, military, space and radiation hardened applications.
Intersil’s roots were planted with Radiation Incorporated in 1950, General Electric Solid State in 1954 and RCA Solid State in 1956. Those three companies would eventually come together as Harris Semiconductor. Harris spun off its entire semiconductor division in 1999 and Intersil was re-born with the largest IPO in American semiconductor industry history. Over the past seven years, Intersil has focused on growth and opportunities in the “pure-play,” high-performance analog semiconductor market.
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 venerable RCA (CDP)1802 microprocessor (aka RCA COSMAC), a CPU traditionally much used in space applications.
