Ultra-Low Power Wireless Mouse Sensor
Introduction
1.1 Overview
PAW3220LU-TJDU is a high performance and ultra-low power CMOS-processed optical image sensor with integrated digital
image process circuits. It is based on an optical navigation technology which measures changes in position by optically
acquiring sequential surface images (frames) and mathematically determining the speed, the direction and the magnitude
of motion. The displacement X and Y information are available in registers which are accessible through SPI serial interface.
A host controller reads and translates the data from the SPI serial interface into RF signals before sending them to the host
PC.
