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 BMA255 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 BMA255 offers a variable V voltage range from 1.2V to 3.6V and can be programmed DDIO to optimize functionality, performance and power consumption in customer specific applications.
