DESCRIPTION
The 3804 group (Spec. H) is the 8-bit microcomputer based on the
740 family core technology.
The 3804 group (Spec. H) is designed for household products, of-
fice automation equipment, and controlling systems that require
analog signal processing, including the A/D converter and D/A
converters.
