GENERAL DESCRIPTION
The MSM82C43 is an input/output port expander device based on CMOS technology and
designed to operate at low power consumption levels.
In systems employing the MSM80C48/49 8–bit single chip microcomputers, 4–bit data can be
expanded by dividing between four I/O lines by executing the MOVDA, P_p, A and ORLDP_p,
A instructions.
FEATURES
• CMOS technology for low power consumption
• 2.5 to 6 V single power supply (dependent on MSM80C48/49 operating frequency.)
• Fully static operation
• Bidirectional I/O ports
• TTL coimpatible (ports 4 thru 7)
• Functional compatiblity with Intel i8243
• Package options
