Zilog was started in California in 1974 by Federico Faggin and Ralph Ungermann. Zilog is an American manufacturer of 8-bit and 16-bit microcontrollers. Its most famous product is the Z80 series, 8-bit microprocessors that were compatible with the Intel 8080 but far less expensive. The Z80 was widely used during the 1980s in many popular home computers such as the TRS-80 and the ZX81. 16 and 32-bit processors were also produced by the company, but these did not see widespread use. From the 1990s the company focused primarily on the microcontroller market. Zilog is a trusted supplier of application specific, embedded system-on-chip (SoC) solutions for the industrial and consumer markets. From its roots as an award-winning architect in the microprocessor and microcontroller industry, Zilog has evolved it’s expertise beyond core silicon to include SoCs, single board computers, application specific software stacks and development tools that allow embedded designers quick time to market in areas such as energy management, monitoring and metering and motion detection.
