The BMA455 is an ultra-small, triaxial, low-g high performance acceleration sensor with digital interfaces, aiming for lowpower and demanding consumer electronics applications. Featuring 14 bit digital resolution and embedded intelligence, the BMA455 allows low-noise measurement of accelerations in 3 perpendicular axes and thus senses significant motion, tilt and enables plug ’n’ play step counting in smartphones and wearable devices. Furthermore the device is optimized to fulfill Android M low power accelerometer requirements. The reduced height of only 0.65 mm is beneficial for wearable devices and low profile smartphones.
