BMA222

Digital, triaxial acceleration sensor

Bosch Sensortec

General description

The BMA222 is an advanced, ultra-small, triaxial,

low-g acceleration sensor with digital interfaces,

aiming for low-power consumer electronics applica-

tions.

The BMA222 allows measurement of accelerations

in 3 perpendicular axes and thus senses tilt, motion,

shock and vibration in cellular phones, handhelds,

computer peripherals, man-machine interfaces,

virtual reality features and game controllers.

BMA222 target applications

Sensor features

With its size of only 2 mm x 2 mm the BMA222

represents a new generation of digital accelerati-

on sensors. The BMA222 integrates a multitude of

features that facilitate its use especially in the area

of motion detection applications, such as device ori-

entation detection, gaming, HMI and menu browser

control. Featuring a full operation current consump-

tion of only 139 µA the BMA222 is ideally suited for

mobile consumer electronic devices. In low-power

mode operation the current consumption can be

even further reduced by almost one order of mag-

nitude.

The BMA222 is highly configurable in order to give

the designer full flexibility when integrating the sen-

sor into his system.

Sensor operation

The BMA222 supports two modes of operation:

1) Streaming data mode: Acceleration data is directly

read-out via the sensor’s digital interface and comput-

ed by a system µController, application processor or a

base-band processor.

2) Interrupt engine mode: Acceleration data is com-

puted already within the BMA222 by the integrated,

programmable interrupt engine. Depending on the

programmable settings the integrated interrupt engine

of the BMA222 signals the occurrence of certain

events via the sensors` two interrupt pins. The corres-

ponding registers of the BMA222 can easily be set and

read-out via the digital sensor interface.
