General description
The BMA222 is a triaxial, low-g acceleration sensor with digital output for consumer market
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 BMA222 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 BMA222 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.
The BMA222 senses tilt, motion and shock vibration in cell phones, handhelds, computer
peripherals, man-machine interfaces, virtual reality features and game controllers.
