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 a DMA controller.[2] It uses separate read and write strobes, sharing similar timings with the Z80 and Intel processors.[3] 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.[4]
