  • Manufacturer Part No CP82C55AZ

Product Overview

The CP82C55AZ is a high performance CMOS Programmable Peripheral Interface, version of the industry standard 8255A and is manufactured using a self-aligned silicon gate CMOS process (Scaled SAJI IV). It is a general purpose programmable I/O device which may be used with many different microprocessors. There are 24 I/O pins which may be individually programmed in 2 groups of 12 and used in 3 major modes of operation. The high performance and industry standard configuration of the 82C55A make it compatible with the 80C86, 80C88 and other microprocessors. Static CMOS circuit design insures low operating power. TTL compatibility over the full military temperature range and bus hold circuitry eliminate the need for pull-up resistors. The Intersil advanced SAJI process results in performance equal to or greater than existing functionally equivalent products at a fraction of the power.
  • Pin compatible with the NMOS 8255A
  • 24 Programmable I/O pins
  • Fully TTL compatible
  • High speed, no "Wait State" operation
  • Direct bit set/reset capability
  • Enhanced control word read capability
  • L7 process
  • 2.5mA Drive capability on all I/O ports
  • 10μA Low standby power (ICCSB)
