MPU-6000/6050: World’s First Integrated 3-Axis Gyro, 3-Axis Accel and 9-Axis MotionFusion™

Overview

InvenSense Six Axis Gyroscope and Accelorometer with Embedded Digital Motion Processor

The MPU-6000™ family provides the world’s first integrated 6-axis MotionProcessing™ solution that eliminates the package-level gyro/accel cross-axis misalignment associated with discrete solutions. The devices combine a 3-axis gyroscope and a 3-axis accelerometer on the same silicon die together with an onboard Digital Motion Processor™ (DMP™) capable of processing complex 9-axis MotionFusion algorithms. The parts’ integrated 9-axis MotionFusion algorithms access external magnetometers or other sensors through an auxiliary master I2C bus, allowing the devices to gather a full set of sensor data without intervention from the system processor. The devices are offered in the same 4x4x0.9 mm QFN footprint and pinout as the current MPU-3000™ family of integrated 3-axis gyroscopes, providing a simple upgrade path and making it easy to fit on space constrained boards.

The InvenSense MotionApps™ Platform that comes with the devices abstracts motion-based complexities, offloads sensor management from the operating system and provides a structured set of APIs for application development.

For precision tracking of both fast and slow motions, the parts feature a user-programmable gyro full-scale range of ±250, ±500, ±1000, and ±2000°/sec (dps) and a user-programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g.

The MPU-6000 family is comprised of two parts, the MPU-6000 and MPU-6050™, that are identical with two exceptions. The MPU-6050 supports I2C communications at up to 400kHz and has a VLOGIC pin that defines its interface voltage levels; the MPU-6000 supports SPI at up to 20MHz, in addition to I2C, and has a single supply pin, VDD, which is both the device’s logic reference supply and the analog supply for the part. The package size of MPU devices has been driven down to a revolutionary footprint of 4x4x0.9mm (QFN). Additional features include an embedded temperature sensor and an on-chip oscillator with ±1% variation over the operating temperature range.
