General description
The BMX055 is an integrated 9-axis sensor for the detection of movements and rotations and
magnetic heading. It comprises the full functionality of a triaxial, low-g acceleration sensor, a
triaxial angular rate sensor and a triaxial geomagnetic sensor.
The BMX055 senses orientation, tilt, motion, acceleration, rotation, shock, vibration and heading
in cell phones, handhelds, computer peripherals, man-machine interfaces, virtual reality
features and game controllers.
Advanced evaluation circuitry (ASIC) converts the outputs of the micro-electromechanical and
geomagnetic sensing structures (MEMS), developed, produced and tested in BOSCH facilities.
The programmable on-chip interrupt engine enables motion-based applications without use of a
microcontroller by providing contextual status of accelerometer, gyroscope and geomagnetic
sensor. The integrated FIFO memories allow buffering the inertial sensor data.
The corresponding chip-sets are integrated into one single 20-pin LGA 3.0mm x 4.5mm x
0.95 mm housing. For optimum system integration the BMX055 is equipped with digital bi-
2
directional SPI and I C interfaces. To provide maximum performance and reliability each device
is tested and ready-to-use calibrated.
Package and interfaces of the BMX055 have been defined to match a multitude of hardware
requirements. Since the sensor features a small footprint, a flat package and very low power
consumption it is ideally suited for mobile-phone and tablet PC applications.
The BMX055 offers a variable V
DDIO
voltage range from 1.2V to 3.6V and can be programmed
to optimize functionality, performance and power consumption in customer specific applications.
