21IC MEMS supplier [1] STMicroelectronics has introduced an ultra-compact, high-performance electronic compass module. The launch of the new product further expands ST's sensor product lineup, integrating motion sensors and magnetic sensors in a 3x3x1mm micro package to enable advanced navigation and mobile location services for increasingly slim portable consumer electronics (location-based services) , LBS) create new opportunities.

ST's electronic compass provides precise heading, indicating the direction in which the car or pedestrian is traveling, enabling applications including pedestrian dead reckoning, map orientation, display orientation and direction detection. Just point the GPS-equipped mobile device to the relevant target, and with the compass's compass function, the mobile location service application can help consumers find and retrieve nearby information, such as places of interest, hotels, shopping centers.
ST's new digital compass is 60% smaller than the current mass-produced compass, which is the size of a single-function, stand-alone motion sensor. At the same time, the new module boasts impressive high-precision sensing capabilities, extended magnetic field range and minimal measurement noise. The new module's size and performance advantages allow OEMs to add more eye-catching features to their mobile products while staying in sync with consumer electronics miniaturization trends.
The LSM303D module's maximum range, while achieving ±16g (linear acceleration) and ±12 Gauss [2] (magnetic field), provides extremely accurate data output over the full scale range. The module includes a temperature sensor and a FIFO (first in, first out) storage area for advanced motion recognition and intelligent power management applications. The module's advanced features include two programmable interrupt signals. When an event such as motion, mouse click and double click, free fall, etc. is found, the module can immediately notify the microcontroller via the interrupt signal.
Digital Compass is now standard on mobile phones and tablets, and is currently entering consumer electronics such as game consoles and digital cameras. According to the latest research report of well-known market research company IHS iSuppli, the demand for digital compass in the global market is growing rapidly, and it is expected to grow from 270 million in 2010 to 1.58 billion in 2015.
STMicroelectronics' LSM303D electronic compass module will begin mass production in the third quarter of 2012.
