The BMA250 features I
tal serial interfaces. Sensor parameters, like g-ranges
or low-pass filter settings, and also all interrupt engi-
ne settings can be easily programmed via the digital
interfaces.
Integrated interrupt engine
One of the key elements of the BMA250 is the enhan-
ced intelligent interrupt engine that gives the hard-
and software designer full control. Various motion
detection scenarios can be identified by the BMA250
and signaled to the system via two interrupt pins. The
interrupt sources can be freely mapped to either of
the two interrupt pins.

Interrupt parameters (e. g. switching angles and
hysteresis settings for orientation change) can be
configured by the designer and thus perfectly support
the integration of the BMA250 into the user’s system
environment.
System compatibility
The BMA250 has been designed for best possible fit
into modern mobile consumer electronics devices.
Besides the ultra-small footprint and lowest power
consumption, the BMA250 has very wide ranges for
