Zilog Z180

The Zilog Z180 is an 8-bit processor and successor of the Z80 CPU. The Z180 retains a significant amount of backwards compatibility with the Z80, while adding many new features that extends the life of the series of processors. In addition to higher clock speeds, the Z180 family adds integrated peripherals such as a clock generator, 16-bit counters/timers, an interrupt controller, wait-state generators, serial ports and a DMA controller. The processor also integrates a MMU that supports configurable banks of memory in 64KB blocks and allows the virtual addressing of up to 1MB of memory.
