The BMA220 is an ultra small triaxial, low-g acceleration sensor with digital interfaces, aiming for low-power consumer market applications.

The BMA220 allows measurement of accelerations in 3 perpendicular axes and thus senses tilt, motion, shock and vibration in cell phones, handhelds, computer peripherals, man-machine interfaces, virtual reality features and game controllers.

The BMA220 is highly configurable in order to give the designer full flexibility when integrating the sensor into his system. All features can be set by software via the digital interface. This implies also that even once a hardware platform with the BMA220 exists, it can be modified by software in order to expand the capabilities and use cases.
