Bosch BMX160

The BMX160 is a highly integrated, low power 9- axis sensor that provides precise acceleration and angular rate (gyroscopic) and geomagnetic measurement in each spatial direction. The BMX160 integrates: 16 bit digital, triaxial accelerometer 16 bit digital, triaxial gyroscope Geomagnetic sensor The BMX160 is a 9- axis sensor consisting of a state- of- the- art 3- axis, low- g accelerometer, a low power 3- axis gyroscope and a 3- axis geomagnetic sensor. It has been designed for low power, high precision 9- axis applications in mobile phones, tablets, wearable devices, remote controls, game controllers, head- mounted devices and toys. Due to the small form factor of the compact 14- pin 2.5 x 3.0 x 0.95 mm^3 LGA package, BMX160 can be ideally integrated into wearables like smart watches or glasses for augmented reality. When accelerometer and gyroscope are in full operation mode and the geomagnetic sensor in normal mode, power consumption is typically 1465 μA, enabling always- on applications in battery driven devices. The BMX160 offers a wide V_DD voltage range from 1.71 V to 3.6 V and a V_DDIO range from 1.2 V to 3.6 V, allowing the BMX160 to be powered at 1.8 V for both V_DD and V_DDIO. Due to its built- in timing unit to synchronize the sensor data, BMx160 is ideally suited for immersive gaming and navigation applications, which require highly accurate sensor data fusion. The BMx160 provides high precision sensor data together with the accurate timing of the corresponding data. The timestamps have a resolution of only 39 μs The integrated 1024 byte FIFO buffer supports low power applications and prevents data loss in non- real- time systems. The intelligent FIFO architecture allows dynamic reallocation of FIFO space for accelerometer, gyroscope and magnetometer, respectively. For typical 9- DoF applications, this is sufficient for approx. 0.5 s of data capture. Like its predecessors, the BMx160 features an on- chip interrupt engine enabling low- power motion- based context awareness. Examples of interrupts that can be issued in a power efficient manner are: any- or no- motion detection, tap or double tap sensing, orientation detection, freefall or shock events. The BMx160 is Android 6.0 (Marshmallow) certified, and in the implementation of the Significant Motion and Step Detector interrupts, each consumes less than 30 μA The smart built- in power management unit (PMU) can be configured, for example, to further lower the power consumption by automatically sending the gyroscope temporarily into fast start- up mode and waking it up again by internally using the any- motion interrupt of the accelerometer. By allowing longer sleep times of the host, the PMU contributes to significant further power saving on system level.
