Bosch BMX055

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). 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 3.0mmx4.5mmx0.95mm housing. For optimum system integration the BMx055 is equipped with digital bidirectional SPI and I²C 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 VDDIO voltage range from 1.2V to 3.6V and can be programmed to optimize functionality, performance and power consumption in customer specific applications.
