Z80182

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 bits CRC
Two UART (serial controller interface) channels
Internal configurable address decoder
Three PIA (Programmable I/O adapter) ports
Two 16 bits 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 and has a low EMI option that reduces the slewrate of the outputs. It's available in several maximum operating frequencies (upto 33MHz) and in 3V3 versions.
