EM83807 - ALL-IN-ONE PLUG & PLAY 3-BUTTON SERIAL MOUSE CONTROLLER

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.

Key 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. B.
