MPU-3000 Triple Axis Gyroscope with Embedded Digital Motion Processor™

Overview

InvenSense Triple Axis Gyroscope with Embedded Digital Motion Processor

The MPU-3000™ family of Motion Processing Units™ features the industry’s first 3-axis gyroscope with an embedded Digital Motion Processor™ (DMP) hardware accelerator engine. Today’s multi-purpose smart phones require a small, low-power gyro to provide wide bandwidth for motion-based gaming as well as high sensitivity and low noise performance for navigation assistance, video and still image stabilization and accurate gesture user interface control. The MPU-3000 provides a series of industry first features for complete motion processing in smart phones including the widest range of motions from 250 to over 2000°/sec, built-in 16-bit ADCs, programmable digital filters, factory calibration to 1% sensitivity, built-in 6-axis MotionFusion™ and 13mW power consumption.

With a 4x4x0.9mm footprint and I²C or SPI digital interfaces, the MPU-3000 MotionProcessor™ family is the first of its kind to address handset requirements. The MPU-3000 extends the traditional inertial sensor architecture with the industry’s first embedded DMP, together with an embedded FIFO, which offloads high-frequency motion algorithm computation from the host application processor, reducing interrupts and host MIPS to improve overall system performance.

The MPU-3000 also integrates a secondary I²C interface to link an external accelerometer to the DMP, another first in the market. This enables the DMP to perform 6-axis MotionFusion by integrating output from the gyroscope and accelerometer and report quaternion output to the handset application processor, offloading the host from sensor timing synchronization and MotionFusion computation. Other features of the MPU-3000 include internal clock generation, an embedded temperature sensor, programmable interrupts, and an FSYNC pin for synchronizing image, video and GPS data.

For power supply flexibility, the MPU-3000 has a separate VLOGIC reference pin in addition to its analog supply pin, which sets the logic levels of its I²C interface. The VLOGIC voltage may be anywhere from 1.71V minimum to VDD maximum.

The patented and volume-proven Nasiri-Fabrication™ platform enables highly scalable MEMS fabrication and wafer-level packaging by integrating MEMS and CMOS on a single silicon wafer. This wafer-level integration enables the industry’s lowest noise specification of 0.01%/√Hz, lowest power consumption, and smallest package size at the lowest possible cost.
