MPU-9250 9-Axis Gyroscope + Accelerometer + Magnet

MPU-9250 9-Axis Gyroscope + Accelerometer + Magnet

The MPU-9250 is InvenSense's second-generation 9-axis MotionTracking device for smartphones, tablets, wearable sensors, and other consumer markets. The MPU-9250, delivered in a 3 x 3 x 1 mm QFN package, is the world's smallest 9-axis MotionTracking device and incorporates the latest InvenSense design innovations, enabling dramatically-reduced chip size and power consumption, while at the same time improving performance and cost.

The MPU-9250 is a system in package (SiP) that combines two chips: the MPU-6500, which contains a three-axis gyroscope, a three-axis accelerometer, and an onboard Digital Motion Processor™ (DMP™) capable of processing complex MotionFusion algorithms; and the AK8963, the market-leading three-axis digital compass. The MPU-9250 supports InvenSense's market-proven MotionFusion. A single design can support the MPU-9250 or MPU-6500, providing customers the flexibility to support either device in different product SKUs.

Improvements include supporting the accelerometer low-power-mode with as little as 6.4 µA and it provides improved compass data resolution of 16-bits (0.15 µT per LSB). The full-scale measurement range of ±4800 µT helps alleviate compass placement challenges on complex PCBs.

The MPU-9250 software drivers are fully compliant with Google's Android 4.1 Jelly Bean release, and support new low-power DMP capabilities that offload the host processor to reduce power consumption and simplify application development. The MPU-9250 includes MotionFusion and run-time calibration firmware that enables consumer electronics manufacturers to commercialize cost-effective motion-based functionality.
