DESCRIPTION
The 3802 group is the 8-bit microcomputer based on the 740 family 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, refer to the section on group expansion.
