EM83702 - ALL IN ONE MOUSE CONTROLLER

General Description

The EM83702 Mouse Controller is specially designed to control mouse device.

This single chip can interface three key-switches and four photo-couple direct to RS-232C.

The EM83702 does not need any external power supply,so the mouse can go without a power line.

Key Features

  • Built-in two zener diode between VDD and VSS, RTS and VDD. Buit-in noise immunity circuit. CMOS DIP 16 pins package & SOP 16 pins package. Low power dissipation. Use 32.768 kHz crystal or 3.58MHz resonator. Oscillator circuits on-chip. Serial output in 1200 baud rate. Can be powered directly from RS-232C. Can drive directly to RS-232C. Three key-switches and four phot.

ALL IN ONE MOUSE CONTROLLER Patent Number : 38715, 95661 (R.O.C) Patent Pending : 84200836 (R.O.C) ALL IN ONE MOUSE CONTROLLER EM83702 EM83702 GENERAL DESCRIPTION The EM83702 Mouse Controller is specially designed to control mouse device. This single chip can interface three key-switches and four photo-couple direct to RS-232C. The EM83702 does not need any external power supply,so the mouse can go without a power line. It is versatile with both microsoft and mouse system. Debouncing circuit were provided to prevent false entry and to improve the accuracy. In 1200 baud rate non-auto speed with 200 DPI wheels and photo-couples, the scanning is 650 mm/sec without missing a dot in microsoft mode,and the scanning speed can up to 770 mm/sec in mouse system mode.
