PS/2 SCROLLING MOUSE
CONTROLIER
DESCRIPTION
The SC84510 Scrolling Mouse Controller is specially designed to
control PS/2 mouse device. This single chip can interface three key-
switches four photo-couples plus x-axis direct to 8042 controller.
SC84510 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.
In the traditional mouse, a great number of noises are generated
when the grid is partially closed or opened. These noises are usually
mistaken for movement signals by traditional mouse controller and
the cursor of the display screen is thus moved frequently up and
down or back and forth. This will consume a great amount of energy.
The SC84510 mouse controller provides noise immunity circuits to
eliminate these noises in order to reduce energy consumption.
FEATURES
* Using 50k
±
5% resistor for RC oscillation.

* Built-in current comparator for photo-couples input.
* Built-in three steps dynamic input impedance.
* Three key-switches and four photo-couples inputs.
* Both key-press and key-release debounce interval 12 ms.
* The sampling rate of motion detector is about 65KHz.
DIP-16
* Low power dissipation.
* Six types Z direction input:
1. Photo couples input. (Z/1)
2. Key-switches input.
