Digital, triaxial acceleration sensor
Bosch Sensortec
General description
The BMA250 is an advanced, ultra-small, triaxial,
low-g acceleration sensor with digital interfaces,
aiming for low-power consumer electronics applica-
tions.
The BMA250 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.

Sensor features
With its size of only 2 mm x 2 mm the BMA250
represents a new generation of digital accelerati-
on sensors. The BMA250 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 BMA250 is ideally suited for
mobile consumer electronic devices. In low-power
mode operation the current consumption can be
even further reduced by more than one order of
magnitude.
The BMA250 is highly configurable in order to give
the designer full flexibility when integrating the sen-
sor into his system.

Sensor operation
The BMA250 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 BMA250 by the integrated,
programmable interrupt engine. Depending on the
programmable settings the integrated interrupt engine
of the BMA250 signals the occurrence of certain
events via the sensors` two interrupt pins. The corres-
ponding registers of the BMA250 can easily be set and
read-out via the digital sensor interface.
