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 HD64180 is a Z80-based embedded microprocessor developed by Hitachi with an integrated memory management unit (MMU) and on-chip peripherals. [1] It appeared in 1985. [ 2 ] The Hitachi HD64180 "Super Z80" was later licensed to Zilog and sold by them as the Z64180 and with some enhancements as the Zilog Z180 .
Programming the Z80 is a seminal computer programming text, written by Rodnay Zaks and first published in 1979 by Sybex. It is designed as both an educational text to teach programming techniques of elementary to intermediate level using assembly language , and as a self-contained reference book.
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 .

R800. The R800 is the central processing unit used in the MSX Turbo-R home computer.The R800 was designed by ASCII Corporation of Japan and built by Mitsui & Co The goal was a modern and pipelined CPU binary compatible with the Z80, and therefore with MSX software, while also maintaining compatibility with older MSX Z80-based hardware.
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. Described at the time as a "mainframe on a chip", the processor is in many ways an equivalent to Intel's ...
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 ...
