The Zilog Z80 is an 8-bit microprocessor designed by Zilog that played an important role in the evolution of early computing. Launched in 1976, it was designed to be software-compatible with the Intel 8080 , offering a compelling alternative due to its better integration and increased performance.
Mostek MK3880 (Zilog Z80) die During the introduction of the Z80 , Zilog needed a production partner while they got their own fabs set up. They first signed a production agreement with Synertek , but the company later demanded they sign a second source deal, allowing Synertek to produce and sell the design on their own.
The Dick Smith Super-80 was a Zilog Z80 based kit computer developed as a joint venture between Electronics Australia magazine and Dick Smith Electronics.. It was presented as a series of construction articles in Electronics Australia magazine's August, September and October 1981 issues.
Zilog, Inc. is an American manufacturer of microprocessors, microcontrollers, and application-specific embedded system-on-chip (SoC) products. The company was founded in 1974 by Federico Faggin and Ralph Ungermann, who were soon joined by Masatoshi Shima.
The Z80 Operating System with Relocatable Modules and I/O Management (Z80-RIO) is a general-purpose operating system developed by Zilog in the late 1970s for various computer systems including the Z80 Micro Computer System (MCZ-1) series [1] and the Z80 Development System (ZDS). [2]
The NEC μCOM series is a series of microprocessors and microcontrollers manufactured by NEC in the 1970s and 1980s. The initial entries in the series were custom-designed 4 and 16-bit designs, but later models in the series were mostly based on the Intel 8080 and Zilog Z80 8-bit designs, and later, the Intel 8086 16-bit design.
The Z80 ceased production in 2024. The Zilog Z8 micro controller (1978) was one of the first single-chip microcontrollers in the market. It integrated an 8-bit CPU, RAM, ROM and I/O facilities, sufficient for many control applications. Faggin conceived the Z8 in 1974, soon after he founded Zilog, but then decided to give priority to the Z80.
Zilog subsequently announced an agreement to manufacture the WE32100 chipset for a five year period, being the first alternative source of these products. [51] There was a Z8000 version of the Xenix Operating System. [52] In 1982, Digital Research and Zilog announced an agreement to make CP/M available for the Z8000. [53]
