82C55A
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.
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.

NOTE: Intersil Pb-free products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate termination
finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL classified at Pb-
free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
