DESCRIPTION

The 3802 group is the 8-bit microcomputer based on the 740 fam-

ily core technology.

The 3802 group is designed for controlling systems that require

analog signal processing and include two serial I/O functions, A-D

converters, and D-A converters.

The various microcomputers in the 3802 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 3802 group, re-

fer to the section on group expansion.
