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 BMA223 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 BMA223 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.
