DESCRIPTION
The 38C1 group is the 8-bit microcomputer based on the 740 fam-
ily core technology.
The 38C1 group has the LCD drive control circuit, an 8-channel A-
D converter, and serial I/O as additional functions.
The various microcomputers in the 38C1 group include variations
of internal memory size and packaging. For details, refer to the
section on part numbering.
