MPU-9150 Nine-Axis (Gyro + Accelerometer + Compass) MEMS MotionTracking™ Device


The world’s first 9-axis MotionTracking device designed for the low-power, low-cost, and high-performance requirements of consumer electronics equipment


InvenSense's MPU-9150™InvenSense's MPU-9150™ is the world’s first 9-axis MotionTracking device designed for the low-power, low-cost, and high-performance requirements of consumer electronics equipment including smartphones, tablets, and wearable sensors.

The MPU-9150 incorporates InvenSense’s MotionFusion™ and run-time calibration firmware that enables manufacturers to eliminate the costly and complex selection, qualification, and system level integration of discrete devices in motion-enabled products, and guarantees that sensor fusion algorithms and calibration procedures deliver optimal performance for consumers.

Motion interface is rapidly becoming a key function in many consumer electronics devices including smartphones, tablets, gaming consoles, and Smart-TVs, as it provides an intuitive way for consumers to interact with electronic devices by tracking motion in free space and delivering these motions as input commands.

The MPU-9150 with MotionFusion and run-time calibration firmware enables consumer electronics manufacturers to rapidly commercialize cost-effective motion-based functionality.

The MPU-9150 is a System in Package (SiP) that combines two chips: the MPU-6050, which contains a 3-axis gyroscope, 3-axis accelerometer, as well as an onboard Digital Motion Processor™ (DMP™) capable of processing complex 9-axis MotionFusion algorithms; and the AK8975, a 3-axis digital compass. The part’s integrated 9-axis MotionFusion algorithms access all internal sensors to gather a full set of sensor data. The part is offered in a 4 x 4 x 1 mm LGA package and is upgrade-compatible with the MPU-6050™ integrated 6-axis MotionTracking device, providing a simple upgrade path and making it easy to fit on space constrained boards.

The InvenSense MotionApps™ Platform that comes with the MPU-9150 abstracts motion-based complexities, offloads sensor management from the operating system and provides a structured set of APIs for application development.
