    BMA253

    The BMA253 is a triaxial, low-g acceleration sensor with digital output for consumer applications. It allows measurements of acceleration in three perpendicular axes. An evaluation circuitry (ASIC) converts the output of a micromechanical acceleration-sensing structure (MEMS) that works according to the differential capacitance principle.

    Package and interfaces of the BMA253 have been defined to match a multitude of hardware requirements. Since the sensor features an ultra-small footprint and a flat package it is ingeniously suited for mobile applications.

    The BMA253 offers a variable VDDIO voltage range from 1.2V to 3.6V and 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 use of a microcontroller.

    Applications

    - Display profile switching (portrait/landscape, face-up/face-down switching)

    - Flat detection

    - Tap / double tap sensing

    - Menu scrolling

    - Gaming

    - Advanced power management for mobile devices

    - Shock and free-fall detection

    - Step-counting

    - Tilt compensation for electronic compass

     
     

    Wearables

    A wristband personal alarm clock will make sure that not only will you get up on time but also in sync with your natural biorhythm. A smartwatch can improve your health by detecting poor air quality in your environment. Smart fitness wear can improve the efficiency of your workout by measuring your speed and calorie consumption. What do all these wearable applications have in common? They are made possible by the almost invisible MEMS sensors and clever sensor solutions.
