MITSUBISHI MICROCOMPUTERS
3803/3804 Group
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
DESCRIPTION
The 3803/3804 group is the 8-bit microcomputer based on the 740
family core technology.
The 3803/3804 group is designed for household products, office
automation equipment, and controlling systems that require ana-
log signal processing, including the A-D converter and D-A
converters.
The 3804 group is the version of the 3803 group to which an I
2
C-
BUS control function has been added.
