Rev 11.00
Dec 8, 2015 CMOS Programmable Peripheral Interface
The Intersil 82C55A 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). 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. Features 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. Direct Bit Set/Reset Capability Pb-Free Plus Anneal Available (RoHS Compliant)
(See Ordering Info) Pin Compatible with NMOS 8255A 24 Programmable I/O Pins Fully TTL Compatible High Speed, No “Wait State” Operation with 5MHz and
8MHz 80C86 and 80C88 Enhanced Control Word Read Capability L7 Process 2.5mA Drive Capability on All I/O Ports Low Standby Power (ICCSB) .10пЃA Ordering Information
