GENERAL DESCRIPTION
The EM84510 Scrolling Mouse Controller is specially designed to control PS/2 mouse device. This single chip can interface three key-switches four photo- couples plus z-axis direct to 8042 controller. EM84510 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 dispaly screen is thus moved frequently up and down or back and forth. This will consume a great amount of energy. The EM84510 mouse controller provides noise immunity circuits to eliminat these noise in order to reduce energy consumption.FEATURES
• Using 51k ±5% resistor for RC oscillation.
• Compatible with legacy PS/2 mouse.
• Compatible with Microsoft scrolling mouse.
• Built-in noise immunity circuit.
• Built-in current comparator for photo-couples input.
• Built-in three step dynamic input impedance.
• Three key-switches and four photo-couples inputs.
• Six types Z direction input:
1. Photo couples input. (Z/1) 4. Mechanical input. (Z/1)
2. Key-switches input. 5. Photo couples input. (Z/4)
3. Voltage-sensing input. 6. Mechanical input. (Z/2)
• Both key-press and key-release debounce interval 12 ms.
• The sampilng rate of motion detector is about 65KHz.
• Low power dissipation.
