PAW3212DB-TJDT

ULTRA LOW POWER WIRELESS MOUSE SENSOR

General Description

The PixArt PAW3212DB-TJDT is optimized for red LED based wireless mouse applications. It has low power architecture, high precision

surface tracking ability, automatic power management modes, flexible programmable resolutions, configurable sleep and wake-up time

which make it suitable for power-sensitive wireless mouse application. The PAW3212DB-TJDT is capable of high-speed motion detection

up to the velocity of 30 inches/sec and acceleration of 10g.

General Features

z Single power with wide voltage range

Low Voltage Segment : 1.7V to 2.1V (VDD, VDDA short)

High Voltage Segment : 2.1V to 3.6V (VDDA should connect

a capacitor to GND)

z Selectable 3-wired (default) or 2-wired SPI serial interface

z Selectable 8-bit (default) or 12-bit motion data length for

Delta_X and Delta_Y

z Selectable resolution up to 2400cpi with 38 cpi/ step (based

on x1 lens magnification)

z Motion detection interrupt output

z Tracking speed up to 30ips (inches/sec) and 10g

acceleration

z Built-in Low Power Timer (LPT) for Sleep1/ Sleep2/ Sleep3(1)

mode

z Adaptive frame rate control for extra power saving during

moving at different speeds
