DESCRIPTION
The 3823 group is the 8-bit microcomputer based on the 740 fam-
ily core technology.
The 3823 group has the LCD drive control circuit, an 8-channel A/
D converter, a serial interface, a watchdog timer, a ROM correc-
tion function, and as additional functions.
The various microcomputers in the 3823 group include variations
of internal memory size and packaging. For details, refer to the
section on part numbering.
