38C3 Group

PIN CONFIGURATION (TOP VIEW)

Package type : 80P6N-A

80-pin plastic-molded QFP

DESCRIPTION

The 38C3 group is the 8-bit microcomputer based on the 740 family

core technology.

The 38C3 group has a LCD drive control circuit, a 10-channel A-D

converter, and a Serial I/O as additional functions.

The various microcomputers in the 38C3 group include variations of

internal memory size and packaging. For details, refer to the section

on part numbering.

For details on availability of microcomputers in the 38C3 group, refer

to the section on group expansion.
