One of the key elements of the BMA180 is the intelli-
gent interrupt engine that gives the hard- and software
designer full control. Various motion detection scena-
rios can be identified by the BMA180 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
BMA180 into the user’s system environment.
Another important feature of the BMA180 acceleration
sensor is the power management module. This module
allows for optimizing the sensor’s power consumption
in-line with the specific user requirements. Thus, it is
not necessary to operate the sensor 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 per-
formance mode. Moreover this feature of the BMA180
allows for an intelligent system power management
and thus significant reduction of the whole system’s
power consumption. In particular, this helps increa-
sing battery life-time of any kind of mobile device.
