Z80 The Z80 is an 8-bit microprocessor introduced by Zilog as the startup company's first product. The Z80 was conceived by Federico Faggin in late 1974 and developed by him and his 11 employees starting in early 1975. The first working samples we ...

CPU. It is compatible with the large base of software written for the Z80. 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 a DMA controller. It uses separate read and write strobes, sharing similar timings with the Z80 and Intel processors. The on-chip memory management unit (MMU) has the capability of addressing up to 1 MB of memory. It is possible to configure the Z180 to operate as the

Hitachi HD64180 The HD64180 is a Z80-based embedded microprocessor developed by Hitachi with an integrated memory management unit (MMU) and on-chip peripherals. It appeared in 1985. The Hitachi HD64180 "Super Z80" was later licensed to Zilog and sold by them ...
