GENERAL DESCRIPTION
The EM83812 PnP Scrolling Mouse Controller is specially designed to control serial mouse device.
This single chip can interface three key-switches and 4 X-Y photo-couples plus Z-axis directly to RS-232C.
There are four types Z-axis inputs used to implement scrolling mouse functionality.
FEATURES
• Using 50kΩ ±1 resistor for RC oscillation.
• Compatible with Microsoft serial scrolling mouse.
• 100 bytes PnP ID code could be filled by code layer.
• Built-in noise immunity circuit.
• The sampiling rate of motion detector is up to 65KHz.
• Built-in three zener diodes : one in VDD to VSS, two in RTS to VDD.
• CMOS push-pull RXD output.
• Built-in current comparator for photo-couples input.
• Built-in three step dynamic input impedance.
• Three key-switches and four photo-couples inputs.
• RTS debouncing circuit included.
• Photo couple test mode included.
• Low power dissipation.
• 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)
• Package type:
EM83812AP : 16DIP, Photo couples input. (Z/1) EM83812DP: 16DIP, Mechanical input. (Z/1)
EM83812BP : 16DIP, Key-switches input. EM83812EP : 16DIP, Photo couples input. (Z/4)
