MPU-9150™ 9-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 from Invensense

Image of InvenSense's MPU-9150 Nine-Axis (Gyro + Accelerometer + Compass) MEMS MotionTracking™ DeviceInvenSense'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 on-board 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 mm x 4 mm 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.
