BMA253

Accelerometer

The BMA253 is a triaxial, low-g acceleration sensor with digital output for consumer applications and is ingeniously suited for mobile devices. The BMA253 can be programmed to optimize functionality, performance and power consumption in customer specific applications. In addition, it features an on-chip interrupt controller enabling motion-based applications without a microcontroller. The BMA253 senses tilt, motion, inactivity, and shock vibration in cell phones, handhelds, computer peripherals, man-machine interfaces, virtual reality features, and game controllers.

Technical data

  • Data-ready (e. g. for processor synchronization)
  • Any-motion (slope) detection (e. g. for wake-up)
  • Tap sensing (e. g. for tap-sensitive UI control)
  • Orientation change recognition (e. g. for portrait/landscape switching)
  • Flat detection (e. g. for position sensitive switching)
  • Low-g / high-g detection (e. g. for shock and free-fall detection)
  • No-motion (e.g. for power saving)
