ALL IN ONE MOUSE CONTROLLER

DESCRIPTION

The SC83702 Mouse Controller is specially designed to control

mouse device. This single chip can interface three key-switches and

four photo-couple direct to RS-232C. The SC83702 does not need

any external power supply, so the mouse can go without a power

line. It is versatile with both microsoft and mouse system.

Debouncing circuit were provided to prevent false entry and to

improve the accuracy. In 1200 baud rate non-auto speed with 200

DPI wheels and photo-couples, the scanning is 650mm/sec without

missing a dot in microsoft mode, and the scanning speed can up to

770mm/sec in mouse system mode.
