3807 Group
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
DESCRIPTION
The 3807 group is a 8-bit microcomputer based on the 740 family
core technology.
The 3807 group has two serial I/Os, an A-D converter, a D-A
converter, a real time output port function, a watchdog timer, and an
analog comparator, which are available for a system controller which
controls motors of office equipment and household appliances.
The various microcomputers in the 3807 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 3807 group, refer
to the section on group expansion.
