HARDWARE
PIN CONFIGURATION (TOP VIEW)
Package type : 64P6N-A
64-pin plastic-molded QFP
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.
