General Description
The BMI160 is an inertial measurement unit (IMU) consisting of a state-of-the-art 3-axis, low-g accelerometer and a low power 3-axis gyroscope. It has been designed for low power, high precision 6-axis and 9-axis applications in mobile phones, tablets, wearable devices, remote controls, game controllers, head-mounted devices and toys. The BMI160 is available in a compact 14-pin 2.5 × 3.0 × 0.83 mm3 LGA package. When accelerometer and gyroscope are in full operation mode, power consumption is typically 925 µA, enabling always-on applications in battery driven devices. The BMI160 offers a wide VDD voltage range from 1.71V to 3.6V and a VDDIO range from 1.2V to 3.6V, allowing the BMI160 to be powered at 1.8V for both VDD and VDDIO.
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: typ. 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 I2C 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)
