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.
The Z80 CPU was used in the Sinclair ZX80, ZX81, ZX Spectrum and the Amstrad CPC home computers as well as the MSX architecture and the Microbee and Tandy TRS-80 (models I, II, III, 4, and others). The CP/M-80 operating system (and its huge software library featuring hits like WordStar and dBase ) was known to be the Z80 disk operating system ...
The Zilog eZ80 is an 8-bit microprocessor designed by Zilog as an updated version of the company's first product, the highly-successful Zilog Z80. The eZ80 is binary compatible with the Z80, but operating almost three times faster at the same clock frequency .
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.
The basic architecture, a modified (non-strict) Harvard architecture, is technically very different from the Zilog Z80. Despite this, the instruction set and assembly language syntax are quite similar to other Zilog processors: Load/store operations use the same LD mnemonic (no MOV or MOVEs), typifying instructions such as DJNZ, are the same ...
The Zilog Z80000 is an unreleased 32-bit processor designed by Zilog and completed in 1986. The Z80000 is a 32-bit expansion of the 16-bit Zilog Z8000 with multiprocessing capability, a six-stage instruction pipeline, and a 256-byte cache. It can address 4 gigabytes of RAM, but cannot execute code written for the Z8000 or Z80.

The Zilog Z180 is an 8-bit microprocessor designed by Zilog as a successor to the Z80. It is compatible with the large base of software written for the Z80. [ 1 ] The Z180 family adds higher performance and integrated peripheral functions like clock generator, 16-bit counters/timers, interrupt controller, wait-state generators, serial ports and ...
