3 Product Overview

3.1 MPU-9150 Overview

MotionInterface™ is becoming a “must-have” function being adopted by smartphone and tablet

manufacturers due to the enormous value it adds to the end user experience. In smartphones, it finds use in

applications such as gesture commands for applications and phone control, enhanced gaming, augmented

reality, panoramic photo capture and viewing, and pedestrian and vehicle navigation. With its ability to

precisely and accurately track user motions, MotionTracking technology can convert handsets and tablets

into powerful 3D intelligent devices that can be used in applications ranging from health and fitness

monitoring to location-based services. Key requirements for MotionInterface enabled devices are small

package size, low power consumption, high accuracy and repeatability, high shock tolerance, and application

specific performance programmability – all at a low consumer price point.

The MPU-9150 is the world’s first integrated 9-axis MotionTracking device that combines a 3-axis MEMS

gyroscope, a 3-axis MEMS accelerometer, a 3-axis MEMS magnetometer and a Digital Motion Processor™

(DMP™) hardware accelerator engine. The MPU-9150 is an ideal solution for handset and tablet

applications, game controllers, motion pointer remote controls, and other consumer devices. The MPU-

9150’s 9-axis MotionFusion combines acceleration and rotational motion plus heading information into a

single data stream for the application. This MotionProcessing™ technology integration provides a smaller

footprint and has inherent cost advantages compared to discrete gyroscope, accelerometer, plus

magnetometer solutions. The MPU-9150 is also designed to interface with multiple non-inertial digital

sensors, such as pressure sensors, on its auxiliary I2C port to produce a 10-Axis sensor fusion output. The

MPU-9150 is a 3rd generation motion processor and is footprint compatible with the MPU-60X0 and MPU-

30X0 families.

The MPU-9150 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 13-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 ±1200µT.

The MPU-9150 is a multi-chip module (MCM) consisting of two dies integrated into a single LGA package.

One die houses the 3-Axis gyroscope and the 3-Axis accelerometer. The other die houses the AK8975 3-

Axis magnetometer from Asahi Kasei Microdevices Corporation.

An on-chip 1024 Byte FIFO buffer helps lower system power consumption by allowing the system processor

to read the sensor data in bursts and then enter a low-power mode as the MPU collects more data. With all

the necessary on-chip processing and sensor components required to support many motion-based use

cases, the MPU-9150 uniquely supports a variety of advanced motion-based applications entirely on-chip.

The MPU-9150 thus enables low-power MotionProcessing in portable applications with reduced processing

requirements for the system processor. By providing an integrated MotionFusion output, the DMP in the

MPU-9150 offloads the intensive MotionProcessing computation requirements from the system processor,

minimizing the need for frequent polling of the motion sensor output.

Communication with all registers of the device is performed using I2C at 400 kHz. Additional features include

an embedded temperature sensor and an on-chip oscillator with ±1% variation over the operating

temperature range.

By leveraging its patented and volume-proven Nasiri-Fabrication platform, which integrates MEMS wafers

with companion CMOS electronics through wafer-level bonding, InvenSense has driven the MPU-9150

package size down to a revolutionary footprint of 4x4x1mm (LGA), while providing the highest performance,

lowest noise, and the lowest cost semiconductor packaging required for handheld consumer electronic

devices. The part features a robust 10,000g shock tolerance, and has programmable low-pass filters for the

gyroscopes, accelerometers, magnetometers, and the on-chip temperature sensor.
