82C55A  
CMOS Programmable  
Peripheral Interface  
June 1998  
Features  
Description  
• Pin Compatible with NMOS 8255A  
• 24 Programmable I/O Pins  
• Fully TTL Compatible  
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.  
• 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
