The '''Zilog Z180''' is an [[8-bit computing|8-bit]] microprocessor designed by [[Zilog]] as a successor to the [[Zilog Z80|Z80]]. It is compatible with the large base of software written for the Z80.<ref>{{cite web|url=http://www.z80.info/z80lives.htm|quote=The designers picked an architecture compatible with the Z80, giving Z80 users a completely software compatible upgrade path|title=The Z80 Lives!|last=Ganssle|first=Jack|year=1992}}</ref> 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.<ref>{{cite book|page=13|isbn=978-0-12-274880-6|author=Jack G.

It is possible to configure the Z180 to operate as the [[Hitachi HD64180]].<ref>{{cite web |title=Z80 Application Note: Migrating from the Hitachi HD64180 to ZiLOG's Z80180, page 7 Summary |url=http://www.zilog.com/appnotes_download.php?FromPage=DirectLink&dn=AN0026&ft=Application%20Note&f=YUhSMGNEb3ZMM2QzZHk1NmFXeHZaeTVqYjIwdlpHOWpjeTk2TVRnd0wyRndjRzV2ZEdWekwyaGtOalF4T0RBdGJXbG5jbUYwYVc5dUxuQmtaZz09 |website=zilog.com/appnotes_download.php |publisher=Zilog Inc. |access-date=May 20, 2019}}</ref>
