The device features the industry's first self-calibrating gyroscope using Component Re-Trimming (CRT) functionality, which compensates for MEMS soldering drifts and ensures post-soldering sensitivity errors down to +\/-0.4%. The accelerometer offers extremely low zero-g offset (+\/-20mg), low sensitivity error (+\/-0.4%), and low noise density (160ug\/sqrtHz). Programmable measurement ranges cover +\/-2g to +\/-16g for the accelerometer and +\/-125dps to +\/-2000dps for the gyroscope. The dual SPI\/I2C interface supports simultaneous OIS (optical image stabilization) and HMI (human-machine interface) functions on a single chip. Hardware and TimeSync features enable precise timestamping for multi-sensor fusion. The device is pin-to-pin compatible with the BMI160, enabling easy upgrade paths.","working_principle":"The BMI260 integrates MEMS sensing elements with a signal conditioning ASIC. (1) Accelerometer: A capacitive MEMS sensing element measures acceleration by detecting the displacement of a proof mass suspended by silicon springs. Capacitive fingers on the proof mass and fixed electrodes form a differential capacitor. Acceleration displaces the proof mass, changing the capacitance ratio, which is converted to a digital value by a sigma-delta ADC. (2) Gyroscope: A vibrating MEMS structure (Coriolis vibratory gyroscope) measures angular rate. When the structure vibrates and is rotated, the Coriolis effect causes a perpendicular deflection proportional to the angular rate. This deflection is sensed capacitively and converted to digital output. (3) CRT (Component Re-Trimming): The self-calibration feature applies electrical stimuli to the MEMS structure to measure and compensate for sensitivity changes caused by soldering. This reduces post-soldering sensitivity error from typical MEMS values of 1-3% down to +\/-0.4%. (4) Dual Interface: The primary SPI\/I2C interface provides full register access and data readout. A secondary OIS interface provides low-latency gyro and accel data directly to camera image stabilization controllers.","pin_description":"
