Housed inside a miniature 3 x 5 x 1 mm package with operating current consumption down to just 110 microamps, STâ€™s LSM303DLHC meets the size and power constraints of portable consumer applications with outstanding accuracy and performance.
The integration of high-performance motion and magnetic2 sensing, coupled with superior stability over time and temperature, makes STâ€™s newest digital-compass device particularly suitable for applications such as location-based services, pedestrian dead reckoning, map/display orientation, and direction finding. IHS iSuppli, a leading market research firm, expects the digital compass market to grow at a CAGR of 25%, from $208 million in 2010 up to $638 million in 2015.
The LSM303DLHC module provides extremely accurate output across full-scale extended ranges up to Â±16g (linear acceleration) and Â±8 Gauss3 (magnetic field), boasting a 60% increase in magnetic sensing resolution (2 mGauss) and a 40% reduction in size over devices currently in production. The device embeds a temperature sensor and a programmable FIFO (first-in first-out) memory block. Advanced features include 4D/6D orientation detection and two programmable interrupt signals that enable immediate notification of motion detection, click/double-click events, and other conditions.
STâ€™s newest geo-magnetic module addresses energy efficiency on chip and at the system level with embedded application layers, FIFO blocks, and smart sleep-to-wake-up functionality. With an operating power consumption of just 110 microamps, the device represents a 70% reduction over the recently announced LSM303DLM module, and works with any supply voltage in the range of 2.16 to 3.6V.
STâ€™s LSM303DLHC geo-magnetic module will be available in Q3 2011. Unit pricing is $2.10 for volumes in the range of 100,000 pieces.
