SC83702
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.
