Zilog Z180
From Free net encyclopedia
The Zilog Z180 8-bit processor is a successor of the Z80 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. The on-chip memory management unit (MMU) has the capability of addressing up to 1MB of memory. It is possible to configure the Z180 to operate as the Hitachi 64180.
