Product Summary

The cp82c55a is a high performance CMOS version of the industry standard 8255A and is manufactured using a self-aligned silicon gate CMOS process (Scaled SAJI IV). The cp82c55a is a general purpose programmable I/O device which may be used with many different microprocessors. The cp82c55a is 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 cp82c55a make it compatible with the 80C86, 80C88 and other microprocessors.
