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.
It has the following features:
- Two ESCC channels with 32-bit CRC
- Two UART channels
- Internal configurable address decoder
- Three PIA ports
- Two 16-bit timers
- One CSIO channel
- One MMU that expands the addressing range to 20 bits
- Wait state generator
- Two DMA channels
- Interrupt controller
- Extended instructions
- 16550 MIMIC interface
- Crystal oscillator
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.
