DESCRIPTION
The 3874 group is the 8-bit microcomputer based on the 740 family core technology. The 3874 group includes data link layer communication control circuit, A-D converters, D-A converter, automatic data transfer serial I/O, UART, and watchdog timer etc. The various microcomputers in the 3874 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 3874 group, re
fer to the section on group expansion.
