The MPU-9250 is the company’s second generation 9-axis MotionTracking device for smartphones, tablets, wearable sensors, and other consumer markets. The MPU-9250, delivered in a 3x3x1mm 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 MotionTracking device sets a new benchmark for 9-axis performance with power consumption only 9.3µA and a size that is 44% smaller than the company’s first-generation device. Gyro noise performance is 3x better, and compass full scale range is over 4x better than competitive offerings.
The MPU-9250 is a System in Package (SiP) that combines two chips: the MPU-6500, which contains a 3-axis gyroscope, a 3-axis accelerometer, and an onboard Digital Motion Processor™ (DMP™) capable of processing complex MotionFusion algorithms; and the AK8963, the market leading 3-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 6.4µA of and it provides improved compass data resolution of 16-bits (0.15 µT per LSB). The full scale measurement range of ±4800µT helps alleviate compass placement challenges on complex pcb’s
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.
