EM83807
ALL-IN-ONE PLUG & PLAY 3-BUTTON SERIAL MOUSE CONTROLLER
Preliminary
GENERAL DESCRIPTION
The EM83807 Mouse Controller is specially designed to control serial mouse device.
This single chip can interface three key-switches and 4 X-Y photo-couples directly to RS-232C.
FEATURES
• Include PnP software scrolling function
• Using 50kΩ ±1% resistor for RC oscillation.
• Compatible with Microsoft serial 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.
APPLICATION
• Serial PnP mouse.
