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, Pp, A and ORLDPp,

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
