38C2 Group
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
DESCRIPTION
The 38C2 group is the 8-bit microcomputer based on the 740 family
core technology.
The 38C2 group has an LCD drive control circuit, a 10-channel A-D
converter, and a Serial I/O as additional functions.
The various microcomputers in the 38C2 group include variations of
internal memory size and packaging. For details, refer to the section
on part numbering.
