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 analog 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.
