Description

DESCRIPTION
The 3886 group is the 8-bit microcomputer based on the 740 family core technology.
The 3886 group is designed for controlling systems that require analog signal processing and include two serial I/O functions, A-D converters, D-A converters, system data bus interface function, watchdog timer, and comparator circuit.
The multi-master I2C bus interface can be added by option.
