UM82C55A - CMOS PROGRMMABLE PERIPHERAL INTERFACE

Datasheet Summary

Description

The UM82C55A is a high performance CMOS version of the industry standard 8255A and is manufactured using a selfaligned silicon gate CMOS process.

It is a general purpose programmable I/O device which may be used with many different microprocessors.

Features

  • Pin compatible with NMOS 8255A.
  • 24 programmable I/O pins.
  • Fully TTL compatible.
  • Bus-hold circuitry on all I/O ports eliminates pull-up resistors.
  • High speed, no "wait state" operation with 8M Hz 80C86.
  • Direct bit set/reset capabi lity.
  • Enhanced control word read capabi lity.
  • Single 5V power supply.
  • 2.5mA drive capabi lity on all I/O port outputs.
  • Low standby power -ICCSB = 10llA General.
