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.
