Acal BFi: Digital, 3-axis Accelerometer

The BMA220 is an ultra small tri-axial, 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.
