DATASHEET 82C55A FN2969 Rev 11.01 CMOS Programmable Peripheral Interface Jan 20, 2020 The 82C55A is a high performance CMOS version of the Features industry standard 8255A and is manufactured using a Pb-Free Plus Anneal Available (RoHS Compliant) self-aligned silicon gate CMOS process (Scaled SAJI IV). It (See Ordering Info) is a general purpose programmable I/O device which may be used with many different microprocessors. There are 24 Pin Compatible with NMOS 8255A I/O pins which may be individually programmed in 2 groups 24 Programmable I/O Pins of 12 and used in 3 major modes of operation. The high Fully TTL Compatible performance and industry standard configuration of the 82C55A make it compatible with the 80C86, 80C88 and High Speed, No Wait State Operation with 5MHz and other microprocessors. 8MHz 80C86 and 80C88 Static CMOS circuit design insures low operating power. TTL Direct Bit Set/Reset Capability compatibility over the full military temperature range and bus Enhanced Control Word Read Capability hold circuitry eliminate the need for pull-up resistors. The L7 Process Intersil advanced SAJI process results in performance equal to or greater than existing functionally equivalent products at 2.5mA Drive Capability on All I/O Ports a fraction of the power.
