BMI270 is an Ultra-low power IMU optimized for wearable applications. The device integrates:  16-bit digital, triaxial accelerometer with ±2g/±4g/±8g/±16g range  16-bit digital, triaxial gyroscope with ±125dps/±250dps/±500dps/±1000dps/±2000dps range Key features          Compact standard size LGA mold package, 14 pins, footprint 2.5x3.0mm² height 0.83mm Primary digital interface with 10 MHz slave SPI (4-wire, 3-wire) and up to 1MHz I²C (Fm+) Output data rates (ODR): 25 Hz … 6.4 kHz (gyroscope) and 0.78 Hz … 1.6 kHz (accelerometer) Programmable low-pass filter (accelerometer ∣ gyroscope): bandwidth ca. 5 ∣ 3 … 680 ∣ 890 Hz Wide power supply range: Analog VDD 1.71V … 3.6V and independent VDDIO 1.2V…3.6V Ultra-low current consumption: typ. 685 µA (in full ODR and aliasing-free operation) Performance mode for gyroscope to minimize noise level: typ. < 8 mdps /√Hz. Built-in power management unit (PMU) for advanced power management and low power modes Rapid startup time: 2 ms for gyroscope (in fast start mode) and 2 ms for accelerometer  Freely configurable secondary digital interface  400 kHz I²C (Fm) master interface hub for 1 I2C AUX sensor (e.g. ext. magnetometer, pressure) o data synchronized to IMU  10 MHz slave SPI (4-wire, 3-wire) for high speed, calibration free OIS / Dual OIS (SPI) applications o up to 6.4 kHz ODR, control register access and max. 676 µs group delay  2 KB on-chip FIFO buffer for accelerometer, gyroscope, timestamps, and AUX sensor data   Fast offset error compensation for accelerometer and gyroscope Fast sensitivity error compensation for gyroscope (CRT, max. sensitivity error < 1%)     HW synchronization of accelerometer, gyroscope, and AUX sensor (< 1 µs) Sensortime stamps for accurate system (host) and sensor (IMU) time synchronization (=1.62V, IOL
