The BMA220 digital sensor from Bosch Sensortec is the smallest digital acceleration sensor in LGA housing in the world, according to the company. It measures 2 mm x 2 mm x 0.98 mm, including LGA housing. The new generation of 2 x 2 LGA housings occupies 79% less surface area on a circuit board than that required for the 6 x 6 sensor that marked Bosch Sensortec's market debut in 2005. The reduced dimensions are not linked to a loss in functionality or quality: The BMA220, which has already been delivered in large quantities to OEM customers, is a fully-fledged, triaxial g-sensor with digital data output, four programmable measuring ranges from ±2 g to ±16 g, and integrated evaluation electronics for recognizing specific motion patterns. For use in pedometers (step counters), Bosch Sensortec wrote specific evaluation algorithms tailored to the BMA220, a service that substantially shortened development time for the end device.
