Z80182

From Wikipedia, the free encyclopedia
8-bit microprocessor
Z80182

TheZilog Z80182 is an enhanced, faster version of the olderZ80 and is part of theZ180microprocessor family. It's nicknamed theZilog Intelligent Peripheral Controller (ZIP).

It has the following features:

  • Two ESCC (enhanced serial channel controller) channels with 32-bit CRC
  • TwoUART (serial controller interface) channels
  • Internal configurableaddress decoder
  • Three PIA (Programmable I/O adapter) ports
  • Two 16-bittimers
  • One CSIO (Clocked Serial Input/output) channel
  • One MMU (Memory management Unit) that expands the addressing range to 20 bits
  • Wait state generator
  • TwoDMA 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 lowEMI option that reduces theslew 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]
