Bosch BMI055

The BMI055 is an inertial measurement unit (IMU) for the detection of movements and rotations in 6 degrees of freedom (6DoF). It reflects the full functionality of a triaxial, low-g acceleration sensor and at the same time it is capable to measure angular rates. Both - acceleration and angular rate - in three perpendicular room dimensions, the x-, y- and z-axis. The BMI055 is designed to meet all requirements for consumer applications such as gaming and pointing devices, HMI and image stabilization (DSC and camera-phone). It also senses tilt, motion, inactivity and shock vibration in cell phones, handhelds, computer peripherals, manmachine interfaces, virtual reality features and game controllers. An evaluation circuitry (ASIC) converts the output of the micro-electromechanical sensing structures (MEMS), developed, produced and tested in BOSCH facilities. The corresponding chip-sets are packed into one single LGA 3.0mmx4.5mmx0.95mm housing. For optimum system integration the BMI055 is fitted with digital bi-directional SPI and I²C interfaces. To provide maximum performance and reliability each device is tested and ready-to-use calibrated. Package and interfaces of the BMI055 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 ingeniously suited for mobile-phone and tablet PC applications. The BMI055 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. In addition it features on-chip interrupt controllers enabling motion-based applications without use of a microcontroller.
