The 3804 Group is the 8-bit microcomputer based on the 740 family core technology.

The 3804 Group is designed for household products, office automation equipment, and controlling systems that require analog signal processing, including the A-D converter and D-A converters.

The 3804 Group is the version of the 3803 group to which an I2CBUS control function has been added.
