3850 Group (Spec. H)
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
DESCRIPTION
The 3850 group (spec. H) is the 8-bit microcomputer based on the
740 family core technology.
The 3850 group (spec. H) is designed for the household products
and office automation equipment and includes serial I/O functions,
8-bit timer, and A-D converter.
