3.5.7 BMA253 Acceleration Sensor

The Bosch BMA253 is a low-g acceleration sensor with digital output for measurements of acceleration in three perpendicular axes.

Additional features:
  • 12-Bit sensitivity
  • User selectable acceleration ranges: ±2g, ±4g, ±8g, ±16g
  • On-chip 32 frame First-In First-Out (FIFO)
  • Motion triggered interrupts:
    • New data
    • Any motion detection
    • Single/double tap sensing
    • Orientation recognition
    • Flat detection
    • Low/high-g detection
    • Inactivity detection
  • Operating voltage range: 1.62V to 3.6V
  • Operating current (Normal Mode): 130 μA (typical)
  • Shutdown current (Deep Suspend Mode): 1 μA (typical)
The BMA253 acceleration sensor is connected to the PIC16LF18456 through I2C and a GPIO for the user configurable interrupt outputs.
