DESCRIPTION
The 38C2 group (A version) is the 8-bit microcomputer based on the
740 family core technology.
The 38C2 (A version) 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 (A version) include
variations of internal memory size and packaging. For details, refer
to the section on part numbering.
