The Zilog Z80182 is an enhanced, faster version of the older Z80 and is part of the Z180 microprocessor family. It's nicknamed the Zilog Intelligent Peripheral Controller (ZIP).
It has the following features:
Two ESCC (enhanced serial channel controller) channels with 32-bit CRC
Two UART (serial controller interface) channels
Internal configurable address decoder
Three PIA (Programmable I/O adapter) ports
Two 16-bit timers
One CSIO (Clocked Serial Input/output) channel
One MMU (Memory management Unit) that expands the addressing range to 20 bits
Wait state generator
Two DMA channels
Interrupt controller
Extended instructions
16550 MIMIC interface
Crystal oscillator
It's also fully static (the clock can be halted and no data in the registers will be lost) and has a low EMI option that reduces the slew rate of the outputs.
The Z80182 can operate at 33 MHz with an external oscillator for 5 volt operation or 20 MHz using the internal oscillator for 3.3 volt operation.[1]
