STMicroelectronics launches high-performance LSM303D e-compass module


The integration of motion and magnetic sensing in a tiny 3x3x1mm package opens new possibilities for advanced navigation and location-based services in ever-sleeker portable consumer devices. The ST LSM303D e-compass’ ability to provide accurate heading information – indicate the direction in which a person or vehicle is moving – enables a wide range of applications, including pedestrian dead-reckoning, map/display orientation, and direction finding. Tied to location-based service apps, compassing capabilities can help consumers identify and retrieve information on nearby points of interest, such as historical or geographical points of interest, restaurants or shops, by simply pointing their GPS-equipped mobile devices in the direction of the object concerned.

Reducing the size by 60% over devices currently in production, ST’s new digital compasses have effectively shrunk to the size of single-function, stand-alone motion sensors. At the same time, the new modules boast superior sensing precision with extended magnetic-scale range and minimized measurement noise. The significant size and performance benefits enable OEMs to add new compelling functionality in mobile gadgets while keeping pace in the miniaturization race. ST’s LSM303D e-compass module will start mass production in Q3 2012. Unit pricing is $1.8 for volumes in the range of 1,000 pieces.
