1 / 76 page 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.
