MITSUBISHI MICROCOMPUTERS

3822 Group

SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER

DESCRIPTION

The 3822 group is the 8-bit microcomputer based on the 740 fam-

ily core technology.

The 3822 group has the LCD drive control circuit, an 8-channel

A-D converter, and a serial I/O as additional functions.

The various microcomputers in the 3822 group include variations

of internal memory size and packaging. For details, refer to the

section on part numbering.

For details on availability of microcomputers in the 3822 group, re-

fer to the section on group expansion.
