1.2 Purpose and Scope
This document is a preliminary product specification, providing a description, specifications, and design
relate d in fo rmation o n the MPU-9250™ Motion Tr acking de vice. The device is h oused in a sm all 3x3x1mm
QFN package.
Specifications are subject to change without notice. Final specifications will be updated based upon
characte rization of production silicon. For references to register map and descriptions of in divi dual registers,
pl eas e refer to the MPU-9250 Register Map and Register Descriptions document.
1.3 Product Overvie w
MPU-9250 is a multi-chip mo dule ( MCM ) consisting of two dies integrated into a single QFN packag e. 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
Motion Tracking device that combines a 3-axis gyroscope, 3-axis accelerometer, 3-axis magnetom eter an d 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 pe rform ance for consumers. MPU-9250 is also designed to inter face with multiple no n-i nertial digital
sensors, such as pres sure sensors , on i t s auxiliary I2C port.
MPU-9250 features three 16-bit analog-to-digital converters (ADCs) for digitizing the gyroscope outputs,
three 16-bit ADCs for digitizing the accelerometer outputs, and three 16-bit ADCs for digitizing the
magnetometer outputs. For precision tracking of both fast and slow motions, the parts feature a user-
programmable gyroscope full-scale range of ±250, ±500, ±1000, and ±2000°/sec (dps), a user-
programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g, and a magnetometer full-scale
range of ±4800µT.
Other industry-leading features include programmable digital filters, a precision clock with 1% drift from -
40°C t o 85°C, an embedded temper ature sensor, and pr ogram m able int errupts. The devic e features I2C and
SPI serial interfac es, a VDD operatin g range o f 2.4V to 3.6V, and a separ ate digital IO supply, VDDIO from
1.71V to VDD.
Comm unication with all registers of the de vice is performe d using eithe r I2C at 400kHz or SPI at 1M Hz. For
applications requiring faster communications, the sensor and interrupt registers may be read using SPI at
20MHz.
By leveraging its patented and volume-proven CMOS-MEMS fabrication platform, which integrates MEMS
wafers with compani on CM OS electro nics through wafer-level b onding, In venSe nse has dri ve n the packag e
size down to a footpri nt and thickness of 3x3x1mm, to pro vi de a very small yet high per formance low cost
package. The device provides high robustness by supporting 10,000g shock reliability.
