Description

This device is intended to fit into any 2-chip application (companion MCU) and offers the best compromise between application cost, power and performance.

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
