EMEM883377002
ALL INALOLNINEOMNOE UMSOEUSCEOCNOTNRTROOLLLLEERR
GENERAL DESCRIPTION
Patent Number : 38715, 95661 (R.O.C)
Patent Pending : 84200836 (R.O.C)
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.
FEATURES
• Built-in two zener diode between V and V , RTS and V .
DD SS
DD
• 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 photo-couples inputs.
• Both key-in and key-release debounce interval 13 ms.
• Through three key-switches input, EM83702 can exert seven different output.
• The sampling rate of motion detector is 65 KHz.
APPLICATIONS
• Optical mouse or pen-mouse
• Mechanical mouse or pen-mouse
• Optomechanical mouse or pen-mouse
• Mechanical track ball
• Optomechanical track ball
* This specification are subject to be changed without notice.
