Basic Description

BMI085 is an inertial measurement unit (IMU) for the detection of movements and rotations in 6 degrees of freedom (6-DoF). It includes the functionality of two inertial sensors in one device: an advanced triaxial 16-bit gyroscope and a versatile, leading edge triaxial 16-bit accelerometer.

BMI085 is designed to meet all requirements for high performance consumer applications such as virtual, augmented and mixed reality applications and high-end gaming, platform stabilization applications such as image stabilization, or indoor navigation and dead-reckoning, for example in robotics applications. It also senses tilt, motion, inactivity and shock vibration in handhelds, computer peripherals, man-machine interfaces, virtual reality features and game controllers.

An evaluation circuitry (ASIC) converts the output of the micro-electro-mechanical sensing structures (MEMS), developed, produced and tested in BOSCH facilities. The corresponding chip-sets are packed into one single LGA 3.0mm x 4.5mm x 0.95mm housing. For optimum system integration, BMI085 is fitted with digital interfaces (SPI or I2C), offering a wide VDDIO voltage range from 1.2V to 3.6V. To provide maximum performance and reliability each device is tested and ready-to-use calibrated.

To increase flexibility, both gyroscope and accelerometer can be operated individually, but can also be tied together for data synchronization purposes. The on-chip features comprise FIFOs for acceleration and gyroscope data and interrupt controllers.

BMI085 has an excellent temperature behaviour with an outstanding low temperature coefficient of offset (TCO) and temperature coefficient of sensitivity (TCS).
