PAW3220LU-TJDU: Ultra-Low Power Wireless Mouse Sensor
General Description
The PixArt PAW3220LU-TJDU is an ultralow power and
small form factor optical sensor which is optimized for
infrared LED based wireless mouse applications. It has
high accuracy navigation ability, low power architecture
and automatic power management which make it
suitable for power-sensitive application such as wireless
mouse. The PAW3220LU-TJDU is capable of high-speed
motion detection up to the velocity of 30 inches/sec and
acceleration of 10g. In addition, it has an on-chip
oscillator and a built-in programmable LED current driver.
In order to achieve the best tracking performance, it is
recommended to match the sensor with infrared SMT
LED (LITE-ON LTE-C216-P-W) and PNSR-015-RB3 optical
lens.
Key Features
Single power with wide voltage range of Low Voltage
and High Voltage segments
Selectable 8-bit (default) or 12-bit motion data length
for Delta_X and Delta_Y
Selectable resolution up to ~1800cpi (based on PNSR-
015-RB3 lens)
Motion detection interrupt output
Tracking speed up to 30ips (inches/sec) and 10g
acceleration
Built-in Low Power Timer (LPT) for Sleep1/ Sleep2/
Sleep3(1) mode
Adaptive frame rate control for extra power saving
during moving at different speeds
Programmable LED Current Source (4-bits with
1mA/step) to provide LED with constant current
Applications
Corded and cordless gaming mice
Motion input devices

PAW3220LU-TJDU Product Brief
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.
