MPU-3050™ Triple Axis Gyroscope with Embedded Digital Motion Processor™ (DMP)

The industry's first 3-axis gyroscope with embedded DMP hardware accelerator engine

Image of InvenSense's MPU-3050 Triple-Axis Gyroscope with Embedded Digital Motion ProcessorInvenSense's MPU-3050 features the industry's first 3-axis gyroscope with an embedded DMP hardware accelerator engine. Today's multi-purpose smartphones 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-3050 provides a series of industry-first features for complete motion processing in smartphones including the widest range of motions from 250°/sec to over 2000°/sec, built-in 16-bit ADCs, programmable digital filters, factory calibration to 1% sensitivity, built-in 6-axis MotionFusion™ and 13 mW power consumption.

With a 4 mm x 4 mm x 0.9 mm footprint and I²C digital interface, the MPU-3050 MotionProcessor is the first of its kind to address handset requirements. The MPU-3000 family 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-3050 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 family 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-3050 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 1.71 V minimum to VDD maximum.
