82C55A June 1998 CMOS Programmable Peripheral Interface Description 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. Features • 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 • 2.5mA Drive Capability on All I/O Ports • Low Standby Power (ICCSB) . . . . . . . . . . . . . . . . .10µA Ordering Information PART NUMBERS 5MHz 8MHz CP82C55A-5 IP82C55A-5 CS82C55A-5 IS82C55A-5 CD82C55A-5 ID82C55A-5 8406601QA CP82C55A IP82C55A CS82C55A IS82C55A CD82C55A ID82C55A 8406602QA PACKAGE 40 Ld PDIP 44 Ld PLCC 40 Ld CERDIP SMD# TEMPERATURE RANGE 0oC to 70oC -40oC to 85oC 0oC to 70oC -40oC to 85oC 0oC to 70oC -40oC to 85oC -55oC to 125oC -55oC to 125oC PKG.
