Description
The MPU-9250 is a 9-axis
MotionTracking device that combines a 3-axis gyroscope, 3-axis
accelerometer, 3-axis magnetometer and a Digital Motion Processor™ (DMP)
all in a small 3x3x1mm package available as a pin-compatible upgrade
from the MPU-6515. With its dedicated I2C sensor bus, the MPU-9250
directly provides complete 9-axis MotionFusion™ output. The MPU-9250
MotionTracking device, with its 9-axis integration, on-chip
MotionFusion™, and run-time calibration firmware, enables manufacturers
to eliminate the costly and complex selection, qualification, and system
level integration of discrete devices, guaranteeing optimal motion
performance for consumers. MPU-9250 is also designed to interface with
multiple non-inertial digital sensors, such as pressure sensors, on its
auxiliary I2C port. 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-9250or MPU-6500, providing customers the flexibility to support either device in different product SKUs.
