82C55AC-2

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.

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.
