CMOS Programmable Peripheral Interface
Features
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.
• 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
• Direct Bit Set/Reset Capability
• Enhanced Control Word Read Capability
• L7 Process
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.
• 2.5mA Drive Capability on All I/O Ports
• Low Standby Power (ICCSB). . . . . . . . . . . . . . . . . . .10μA

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.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
