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 I2
C 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 I2
C port.

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.
