'''Zilog, Inc.''' is an American manufacturer of [[8-bit]] and [[16-bit]] [[microcontroller]]s. Its most famous product is the [[Zilog Z80|Z80]] series of [[8-bit]] [[microprocessor]]s that were compatible with the [[Intel 8080]] but significantly cheaper. The Z80 was widely used during the 1980s in many popular [[home computer]]s such as the [[TRS-80]], [[MSX]], [[Amstrad CPC]] and the [[ZX Spectrum]], as well as arcade games such as ''[[Pac-Man]]''. The company also made 16- and 32-bit processors, but these did not see widespread use. From the 1990s, the company focused primarily on the microcontroller market.

==History==
Zilog was started in [[California]] in 1974 by [[Federico Faggin]] and [[Ralph Ungermann]],<ref name=oral>{{cite web|url=http://archive.computerhistory.org/resources/text/Oral_History/Zilog_Z80/102658073.05.01.pdf|title=ZILOG Oral History Panel on the Founding of the Company and the development of the Z80 Microprocessor}}</ref><ref>{{cite web|url=httphttps://www.historyofcomputercommunications.info/Organizationssection/Startups9.6/Ungerman-Basszilog/UngermanBassHome.html|title= 9.6 Zilog Ungerman-Bass in Brief}}</ref> who both left [[Intel]] after working on the [[Intel 4004|4004]] and [[Intel 8080|8080]] microprocessors and custom chips. [[Masatoshi Shima]], who also worked with Faggin on the 4004 and 8080, joined Zilog in 1975. Ungermann had a falling-out with Faggin and left Zilog in 1978. The company became a [[subsidiary]] of [[Exxon]] in 1980, but the management and employees bought it back in 1989, led by Dr. [[Edgar Sack]].
