Product Summary

The SC84510FP is a Scrolling Mouse Controller, specially designed to control PS/2 mouse device. This single chip can interface three keyswitches four photo-couples plus x-axis direct to 8042 controller. The SC84510FP can receive command and echo status or data format which are compatible with IBM PS/2 mode mouse. Key debouncing circuit is provided to prevent false entry and improve the accuracy.
