BMX055 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 the use of a microcontroller by providing contextual status of the accelerometer, gyroscope and geomagnetic sensor. The integrated  FIFO  memories allow buffering of the inertial sensor data.
