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.

All parameters and features user programmable
7 user programmable g-ranges and 10 selectable
bandwidth settings
Low-power consumption
Ultra-low-power self-wake-up mode
User programmable interrupt engine
0g offset regulation and in-field offset re-calibration
with ultra-high accuracy
SPI (4-wire) / I²C interface
RoHS compliant, halogen-free
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 ...
