STMicroelectronics 

VT5376

Ultra-low power motion sensor

for optical finger navigation and laser mice

Features

■ Ultra-low power performance and high

speed/high accuracy motion detection

(1 m/s, 20 g)

■ Optional on-chip power management scheme

(RUN/IDLE1/IDLE2/SLEEP)

■ On-chip boost-converter controller enables a

complete autonomous single AA/AAA-type

battery supply application

■ Very low quiescent and operating current mode

for battery life saving

■ I2C interface, with fast polling rate capability for

high end applications

(report rate up to 1 per ms)

■ Internal oscillator

■ CPI programmable up to 3200 CPI

■ On-chip ADC for battery level reporting

■ Laser drive circuitry, fault detection scheme

and safety features

■ Versatile usage: the sensor is designed to

operate with a companion microcontroller, and

can be used for any laser/LED mouse system

■ Optimized for wireless applications

(27 MHz/2.4 GHz/BT).

■ RoHS (lead-free) package

Applications

■ Fingermice applications for mobile phones,

remote controls or MP3 players

■ Ultra-low power wireless laser mouse,

27 MHz, 2.4 GHz and Bluetooth

■ Also suitable for laser USB mouse applications
