Preliminary
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 50k
±
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)
2. Key-switches input.
3. Voltage-sensing input.
Package type:
EM83812AP : 16DIP, Photo couples input. (Z/1) EM83812DP: 16DIP, Mechanical input. (Z/1)
EM83812BP : 16DIP, Key-switches input.
EM83812CP : 16DIP, Voltage-sensing input.
4. Mechanical input. (Z/1)
