   Low-pass filter bandwidths = 0.48*ODR
   up to 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/In-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, 2 interrupt pins
   VDDIO voltage range: 1.2V to 3.6V
• RoHS compliant, halogen-free
