Why it issues: Zilog is retiring the Z80 after 48 years available on the market. Initially developed as a challenge stemming from the Intel 8080, it will definitely rose to change into one of the crucial fashionable and extensively used 8-bit CPUs in each gaming and normal computing gadgets.
The enduring IC system, developed by Federico Faggin, will quickly be phased out, and events solely have just a few months left to put their orders earlier than Zilog’s manufacturing companion ends assist for the know-how.
In response to Zilog’s notification, Wafer Foundry Producer (WFM) will stop accepting “final time purchase” (LTB) orders for the remaining Z80 merchandise in mid-June. Zilog will course of and schedule LTB orders for the Z80 based mostly on clients’ demand, whereas WFM will present precise supply dates thereafter. Relying on the general LTB demand, the corporate could impose stricter necessities on minimal and most portions.
Federico Faggin, an Intel engineer, based Zilog in 1974 after his work on the Intel 4004, the primary 4-bit CPU. The Zilog Z80 was then launched in July 1976, conceived as a software-compatible “extension” and enhancement of the Intel 8080 processor.
Developed by a staff of simply 12 individuals, the Z80 noticed outstanding success, main Zilog to ascertain its personal chip manufacturing vegetation and develop to over a thousand workers inside two years. Like its Intel counterpart, the Z80 was initially designed for embedded techniques however went on to change into a major milestone in gaming {hardware} from the Nineteen Seventies to the mid-Eighties.

A number of dwelling computer systems and gaming consoles have been constructed across the capabilities of the Z80, together with Sega’s Grasp System and SG-1000, and Nintendo’s Recreation Boy and Recreation Boy Coloration. Many traditional arcade video games additionally used the Z80, together with the unique model of Pac-Man. Moreover, the 8-bit processor was frequent in army functions, musical synthesizers just like the Roland Jupiter-8, and varied different digital gadgets.
Zilog licensed its Z80 know-how to US firms Synertek and Mostek, which aided Faggin’s enterprise with manufacturing, in addition to to the European producer SGS/STMicroelectronics. The CPU design was later replicated by Japanese, East European, and Soviet producers, whereas firms resembling NEC, Toshiba, Sharp, and Hitachi produced their very own suitable variations of the chip.
In recent times, Zilog has refocused Z80 manufacturing on the embedded system market, providing superior microcontroller merchandise that retain compatibility with the unique Z80 and Z180 designs.
