MPU6050 Datasheet – MotionTracking devices – InvenSense

Part Number : MPU-6050, MPU6050, MPU-6000, MPU6000

Function : Six-Axis (Gyro + Accelerometer) MEMS MotionTracking Devices

Package : 4 mm x 4 mm x 0.9 mm QFN package.

Manufactures : InvenSense, Inc ( https://www.invensense.com/ )


MPU6050 motion-tracking

The MPU-6050 parts are the world’s first MotionTracking devices designed for the low power, low cost, and high-performance requirements of smartphones, tablets and wearable sensors.

The MPU-6050 incorporates InvenSense’s MotionFusion™ and run-time calibration firmware that enables manufacturers to eliminate the costly and complex selection, qualification, and system level integration of discrete devices in motion-enabled products, guaranteeing that sensor fusion algorithms and calibration procedures deliver optimal performance for consumers.

The MPU-6050 devices combine a 3-axis gyroscope and a 3-axis accelerometer on the same silicon die, together with an onboard Digital Motion Processor™ (DMP™), which processes complex 6-axis MotionFusion algorithms. The device can 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.
