CHMOS PROGRAMMABLE PERIPHERAL INTERFACE

IN82C55AN CHMOS PROGRAMMABLE PERIPHERAL INTERFACE The Integral IN82C55AN is a high-performance, CHMOS version of the industry standard IN82C55AN 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. 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. www.DataSheet4U.com FEATURES • • • • • • • • • • Compatible with all Intel and Most Other Microprocessors High Speed, «Zero Wait State» Operation with 8MHz 8086/88 and 80186/188 24 Programmable I/O Pins Low Power CHMOS Completely TTL Compatible Control Word Read-Back Capability Direct Bit Set/Reset Capability 2.5mA DC Drive Capability on all I/O Port Outputs Available in 40-Pin DIP Available in EXPRESS ƒ Standard Temperature Range ƒ Extended Temperature Range GROUP A CONTROL GROUP A PORT A (8) PA7-PA0 D7-D0 DATA BUS BUFFER 8 BIT INTERNAL DATA BUS GROUP A PORT C UPPER (4) GROUP B PORT C LOWER (4) PC7-PC4 PC3-PC0 RD WR A1 A0 Reset READ/ WRITE CONTROL LOGIC GROUP B CONTROL GROUP B PORT B (8) PB7-PB0 CS PA3 PA2 PA1 PA0 RD CS VSS A1 A0 PC7 PC6 PC5 PC4 PC0 PC1 PC2 PC3 PB0 PB1 PB2 1. 2. 3. 4.
