MSM82C55A-2RS/GS/VJS
CMOS PROGRAMMABLE PERIPHERAL INTERFACE
GENERAL DESCRIPTION
The MSM82C55A-2 is a programmable universal I/O interface device which operates as high
speed and on low power consumption due to 3m silicon gate CMOS technology. It is the best
fit as an I/O port in a system which employs the 8-bit parallel processing MSM80C85AH CPU.
This device has 24-bit I/O pins equivalent to three 8-bit I/O ports and all inputs/outputs are
TTL interface compatible.
FEATURES
• High speed and low power consumption due to 3m silicon gate CMOS technology
• 3 V to 6 V single power supply
• Full static operation
• Programmable 24-bit I/O ports
• Bidirectional bus operation (Port A)
• Bit set/reset function (Port C)
• TTL compatible
• Compatible with 8255A-5
• 40-pin Plastic DIP (DIP40-P-600-2.54): (Product name: MSM82C55A-2RS)
• 44-pin Plastic QFJ (QFJ44-P-S650-1.27): (Product name: MSM82C55A-2VJS)
• 44-pin Plastic QFP (QFP44-P-910-0.80-2K): (Product name: MSM82C55A-2GS-2K)
