Information About

Zilog




Zilog, often seen as '''ZiLOG''' (the official company denotation since 1998), is a manufacturer of 8-bit , 16-bit , 24-bit , and 32-bit CPU s, and is most famous for its Intel 8080 -compatible Z80 series. Zilog was incorporated in California in 1974 by Federico Faggin , who left Intel after working on the 8080. The Z80 was an improved 8080 which was faster, more capable, and much cheaper; alongside the 6502 it was one of the most popular 8-bit processors for general purpose microcomputers and other applications. It was used in the Nintendo Game Boy , the Sinclair ZX80 , ZX81 and ZX Spectrum Home Microcomputer s as well as the MSX architecture and the Tandy TRS-80 series - among many others. Also, many Texas Instruments Graphing Calculator s used the Z80 as the main Processor and in some newer game consoles as a Secondary Processor , like the Mega Drive . The CP/M Operating System (and its huge software library featuring hits like Wordstar and DBase ) was known to be "'''the''' Z80 disk operating system", and its success is partly due to the popularity of the Z80.

After the Z80 Zilog introduced 16-bit and 32-bit processors, but these were not particularly successful, and the company refocused on the Microcontroller market, producing both basic CPUs and Application-specific Integrated Circuits/standard Product s (ASICs/ASSPs) built around a CPU core. As well as producing processors, Zilog has produced several other components. One of the most famous was the Z8530 serial communications controller as found on Sun SPARCstation s and SPARCservers up to the SPARCstation 20 .

The company became a Subsidiary of Exxon in 1980 , but the management and employees bought it back in 1989 . It went public in 1991 , but was acquired in 1998 by Texas Pacific Group , who, after chip prices plummeted, reorganized the company in a Chapter 11 Bankruptcy in late 2001 .
