 Product Description



 MPU-9150 EOL Notice


The 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, and 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 4x4x1mm 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.

For precision tracking of both fast and slow motions, the parts feature a user-programmable gyro full-scale range of ±250, ±500, ±1000, and ±2000°/sec (dps), a user-programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g, and compass with a full scale range of ±1200µT.
