BMA400 3-axes ultra-low power accelerometer
■12 bit, digital, triaxial acceleration sensor with smart on-chip motion and position-triggered interrupt features.
●Key features
■ Small package size:LGA package (12 pins), footprint 2mm x 2mm, height 0.95 mm
■ Ultra-low power:Low current con sumption of data acquisition without compromising on performanee (< 14.5 μA with highest performance)
■ Programmable functionality:
▲Acceleration ranges ±2g/±4g/±8g/±16g
▲Low-pass filter bandwidths = 0.4-8*ODR upto a max output data read out of 800Hz
■ On-chip FIFO:Integrated FIFO on sensor with 1 KB
■ On-chip interrupt features:
▲Auto-low power/Auto wakeup
▲Activity/ln-activity
▲Step Counter (overall device current consumption 4μA)
▲Activity Recognition (Walking, Running, Standing still)
▲Orientation detection
▲Tap/double tap
■Digital interface:
▲SPI (4-wire, 3-wire), I²C interrupt pins
▲V-DDIO voltage range：1.2V to 3.6V
■RoHS compliant, halogen-free
