GENERAL DESCRIPTION
Patent Number : 38715, 95661 (R.O.C)
Patent Pending : 84200836 (R.O.C)
The EM83701 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 EM83701 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.
Using the auto-speed adjusting circuits, EM83701 promotes the power of the mouse in movement. If the mouse
moves at low speed, it will be very smooth. While at high speed, EM83701 series can change the scaning ability
of the motion and detects more dots than at low speed. It is said that horizotal and vertical counters acquire
different dots in the same distance according to different speed.
FEATURES
• Built-in two zener diode between VDD and VSS, RTS and VDD.
• Auto speed with dynamic resolutions.
• Buit-in noise immunity circuit.
• CMOS DIP 16 pins package & SOP 16 pins package.
• Low power dissipation.
• Use 32.768 kHz crystal.
• 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, EM83701 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
