One of the key elements of the BMA220 is the
intelligent interrupt engine that gives the hard- and
software designer full control. Various motion detec-
tion scenarios can be identified by the BMA220 and
signaled to the system via a simple interrupt pin.

By using the digital serial interface, the exact details
of the motion event that triggered the interrupt can
be read-out.
Following motion detection use case scenarios are
supported by the interrupt engine:

The interrupts can be conveniently configured by the
user and thus perfectly support the integration of the
BMA220 into the user’s system environment.
Another important feature of the BMA220 accelera-
tion sensor is the power management module. This
module allows for optimizing the sensor‘s power
consumption in-line with the specific user require-
ments. Thus, it is not necessary to operate the sen-
sor at full power for all application scenarios all the
time. For some use cases the power consumption
drastically shrinks to just a fraction of what would
be required in full performance mode.
Moreover this feature of the BMA220 allows for an
intelligent system power management and thus sig-
nificant reduction of the whole system‘s power con-
sumption. In particular, this helps increasing battery
life-time of any kind of mobile device.
In the unique ”dedicated I/O“ modes the BMA220
can be operated as a stand-alone device without
requiring a µController.
