MPU-9250 is a multi-chip module (MCM) consisting of two dies integrated into a single QFN package. One die
houses the 3-Axis gyroscope and the 3-Axis accelerometer. The other die houses the AK8963 3-Axis
magnetometer from Asahi Kasei Microdevices Corporation.
Hence, 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™
The MPU-9250 MotionTracking device, with its 9-axis integration, on-chip MotionFusion™, and runtime
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 I
