General description
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, man-
machine 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 3.0mm x 4.5mm x 0.95mm housing. For optimum
2
system integration the BMI055 is fitted with digital bi-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 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 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. In
addition it features on-chip interrupt controllers enabling motion-based applications without use
of a microcontroller.
