DESCRIPTION
The 3851 group (built-in 24 KB or more ROM) is the 8-bit micro-
computer based on the 740 family core technology.
The 3851 group (built-in 24 KB or more ROM) is designed for the
household products and office automation equipment and includes
serial I/O functions, 8-bit timer, I2C-BUS interface, and A-D con-
verter.
