3803 General Description

The 3803/3804 group is the 8-bit microcomputer based on the 740 amily core technology.

The 3803/3804 group is designed for household products, office atomation equipment, and controlling systems that require ana-log signal processing, including the A-D converter and D-Aconverters.

The 3804 group is the version of the 3803 group to which an I²C-BUS control function has been added.
