General description
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.
