38C8 Group
DESCRIPTION
The 38C8 group is the 8-bit microcomputer based on the 740 family
core technology.
The 38C8 group has a LCD drive control circuit (bias control, time
sharing control), a 10-bit A-D converter, and a Serial I/O as additional
functions.
The various microcomputers in the 38C8 group include variations of
internal memory size and packaging. For details, refer to the section
on part numbering.
