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.
