... GENERAL DESCRIPTION The M62320P/ CMOS 8-bit I/O expander which has serial to parallel and parallel to serial data converting functions. It can communicate with a microcontroller via few wiring thanks to the adoption of the two-line I C BUS. Parallel data I/O terminal can be set to input or output mode alternatively in individual bits. ...
