MITSUBISHI MICROCOMPUTERS
3820 Group
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
DESCRIPTION
The 3820 group is the 8-bit microcomputer based on the 740 fam-
ily core technology.
The 3820 group has the LCD drive control circuit and the serial I/
O as additional functions.
The various microcomputers in the 3820 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 3820 group, re-
fer to the section on group expansion.
