MODE

FUNCTION Mode selection input. If MODE pin is HIGH, EC3581 will operate in Microsoft System mode. If MODE pin is LOW, EC3581 will operate in Mouse System mode. If MODE pin is floating during the Power On Reset period and one of the buttons is pressed, the EC3581 will operate in Microsoft System mode. Otherwise, it will operate in Mouse System mode. Crystal oscillator input. Crystal oscillator output. Input from RTS (Request To Send) of RS232C. The RXD pin will send a 4D hexadecimal code in Microsoft System Mode after a LOW to HIGH transition of the RTS pin. After 4D code is received, the RTS pin will remain HIGH. Serial data output to Receive Data of RS232C. Normally LOW. Ground pin. Right button selection. BR pin is HIGH when right button is pressed and becomes LOW when it is released. EC3581 will only report through RXD on a rising edge or falling edge of the input signal. The status of BR will be LOW on a falling edge and HIGH on a rising edge. Middle button input. Left button input. Reference voltage for ZENER. Input from the first X axis photo-encoder. In both Microsoft System and Mouse System, PX1 and PX2 constitute positive (negative) counts for rightward (leftward) movement on the screen. Input from the second X axis photo-encoder. Input from the first Y axis photo-encoder. In Microsoft System, PY1 and PY2 constitute positive (negative) counts for downward (upward) moveme nt on the screen. In Mouse System, PY1 and PY2 constitute positive (negative) counts for upward (downward) movement on the screen. Input from the second Y axis photo-encoder. +5V power supply.

E-CMOS CORPORATION LAYOUT DESIGN GUIDELINES
Mounting of Die and Layout for Wire Bond Pads
EC3581-D VERG 1.1
1. A ground potential is required for the die, area for the PCB die pad should be .010" larger than the die, on all sides. 2. For wire bonding manufacturability, the PCB pads should be placed in line with die pads. A. Normal distance between die pad and PCB bond pads: .020" to .100" B. Typical PCB pad size: .005" to .010" square 3. Usual Length of a wire bond: .020" to .100" Ax|sAoO*NAE
