DATASHEET MS82C55A, MQ82C55A, MP82C55A FN6140 Rev 2.00 CMOS Programmable Peripheral Interface June 15, 2006 The Intersil 82C55A is a high performance CMOS version of Features the industry standard 8255A and is manufactured using a Pb-Free Plus Anneal Available (RoHS Compliant) self-aligned silicon gate CMOS process (Scaled SAJI IV). (See Ordering Info) The MX82C55A has identical features as the X82C55 with the exception of no bus hold devices on the port pins. It is a Pin Compatible with OKI MSM82C55A general purpose programmable I/O device which may be - No Bus Hold Devices on any Port Pins used with many different microprocessors. There are 24 I/O 24 Programmable I/O Pins pins which may be individually programmed in two groups of Fully TTL Compatible 12 and used in three major modes of operation. The high performance and industry standard configuration of the High Speed, No Wait State Operation with 8MHz 80C86 82C55A make it compatible with the 80C86, 80C88 and and 80C88 other microprocessors. Direct Bit Set/Reset Capability Static CMOS circuit design insures low operating power. The Enhanced Control Word Read Capability Intersil advanced SAJI process results in performance equal to or greater than existing functionally equivalent products at L7 Process a fraction of the power. 2.5mA Drive Capability on All I/O Ports Low Standby Power (ICCSB) .10A Ordering Information PART NUMBERS* PART TEMP.

They are not intended for use in Reflow solder processing applications. NOTE: Intersil Pb-free plus anneal 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.
