Accelerometer, Gyroscope, IMU. Bosch Sensortec Inertial Sensor BMI160

The BMI160 is a highly integrated, low power inertial measurement unit (IMU) that provides precise acceleration and angular rate (gyroscopic) measurement.

The BMI160 integrates:

• 16-bit digital, triaxial accelerometer
• 16-bit digital, triaxial gyroscope.

Key features

• High performance accelerometer and gyroscope (hardware synchronized)
• Very low power consumption: typically 925 µA (accelerometer and gyroscope in full operation)
• Android Lollipop compatible: significant motion and step detector / step counter (5 µA each)
• Very small 2.5 x 3.0 mm2 footprint, height 0.83 mm
• Built-in power management unit (PMU) for advanced power management
• Power saving with fast start-up mode of gyroscope
• Wide power supply range: 1.71V … 3.6V
• Allocatable FIFO buffer of 1024 bytes (capable of handling external sensor data)
• Hardware sensor time-stamps for accurate sensor data fusion
• Integrated interrupts for enhanced autonomous motion detection
• Flexible digital primary interface to connect to host over I 2C or SPI
• Extended I2C mode with clock frequencies up to 1 MHz
• Additional secondary high speed interface for OIS application
• Capable of handling external sensor data (e.g. geomagnetic or barometric pressure sensors by Bosch Sensortec)
