Bosch BMA253 Triaxial Low-G Acceleration Sensor 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.
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 applications. In addition, the BMA253 features an on-chip interrupt controller that enables motion-based applications without use of 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.
