BMA180
Digital, triaxial acceleration sensor
Bosch Sensortec
General description
The BMA180 is an ultra high performance digital
triaxial acceleration sensor, aiming for low power
consumer market applications.
The BMA180 allows high accurate measurement of
accelerations in 3 perpendicular axes and thus sen-
ses tilt, motion, shock and vibration in cell phones,
handhelds, computer peripherals, man-machine inter-
faces, virtual reality features and game controllers.
BMA180 target applications
Navigation (INS / Dead Reckoning)

Sensor operation
The BMA180 represents a new generation of digital
acceleration sensors with a unique performance and
feature set within 3 mm x 3 mm x 0.9 mm standard
LGA package.

The BMA180 is highly configurable in order to give the
designer full flexibility when integrating the sensor
into his system. All features can be set by software
via the digital interface. Here the user can choose
between an I²C and an SPI (4-wire) interface mode.

    ... Bosch Sensortec BMA180 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 ...
