Acceleration sensor: BMA456
High performance. Thin package. Low TCO.
BMA456
Accelerometer
The BMA456 is an ultra-small, triaxial, low-g high performance acceleration sensor with digital interfaces. The sensor is suitable for low-power and demanding consumer electronics applications. It detects wrist tilt, tab/double tab and enables plug ’n’ play step counting especially in wearable devices.
Easy-to-integrate due to small size
Enhanced speech processing
Continuously usable due to always-on low-power speech processing
Ultra-low power consumption
