Acal BFi: Digital, 3-axis Accelerometer

The BMA222 is an advanced, ultra-small, tri-axial, low-g acceleration sensor with digital interfaces, aiming for low-power consumer electronics applications. The BMA222 allows measurement of accelerations in 3 perpendicular axes and thus senses tilt, motion, shock and vibration in cellular phones, handhelds, computer peripherals, man-machine interfaces, virtual reality features and game controllers.

Features
