The Intel 82C55A is a high-performance CHMOS version of the industry standard 8255A general purpose
programmable I O device which is designed for use with all Intel and most other microprocessors It provides
24 I O pins which may be individually programmed in 2 groups of 12 and used in 3 major modes of operation
The 82C55A is pin compatible with the NMOS 8255A and 8255A-5
In MODE 0 each group of 12 I O pins may be programmed in sets of 4 and 8 to be inputs or outputs In
MODE 1 each group may be programmed to have 8 lines of input or output 3 of the remaining 4 pins are used
for handshaking and interrupt control signals MODE 2 is a strobed bi-directional bus configuration
The 82C55A is fabricated on Intel's advanced CHMOS III technology which provides low power consumption
with performance equal to or greater than the equivalent NMOS product The 82C55A is available in 40-pin
DIP and 44-pin plastic leaded chip carrier (PLCC) packages
