DESCRIPTION
The 3825 group is the 8-bit microcomputer based on the 740 fam-
ily core technology.
The 3825 group has the LCD drive control circuit, an 8-channel A-
D converter, and a Serial I/O as additional functions.
The various microcomputers in the 3825 group include variations
of internal memory size and packaging. For details, refer to the
section on part numbering.
For details on availability of microcomputers in the 3825 Group,
refer the section on group expansion.
