PS/2 MOUSE CONTROLLER

DESCRIPTION

The SC84502 Mouse Controller is specially designed to control

PS/2 mouse device. This single chip can interface three key-

switches and four photo-couples direct to 8042. SC84502 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.

DIP-14

In the conventional mouse,

a great number of noises are

generated when the grid is partially closed or opened. These noise

are usually mistaken for movement signals by conventional mouse

controller and the cursor of the display screen is thus moved

frequently up and down or back and forth. This will consumes a great

amount of energy. The SC84502 PS/2 mouse controller provides

noise immunity circuits to eliminate these noise In order to reduce

energy consumption.
