1. Describe

MotionInterface™ is becoming a "must have" feature for smartphones and tablets Manufacturer, because it adds great value to the end user experience. In smartphones, it is used in applications such as gesture commands for application and phone control, enhanced games, augmented reality, panoramic photo capture and viewing, and pedestrian and vehicle navigation. With its ability to accurately track user movements, MotionTracking technology can transform mobile phones and tablets into powerful 3D smart devices, which can be used for applications such as health and fitness to monitor location-based services. The key requirements for devices supporting MotionInterface are small package size, low power consumption, high accuracy and repeatability, high shock resistance, and application-specific performance programmability—all at a lower consumer price point. MPU-60X0 is the world's first integrated 6-axis MotionTracking device, which combines a 3-axis gyroscope, a 3 axis accelerometer and a digital motion processor™ (DMP) all in a small size of 4x4x0.9 mm pack. With its dedicated I2C sensor bus, it directly accepts input from an external 3-axis compass to provide a complete 9-axis MotionFusion™ output. The MPU-60X0 MotionTracking device with 6-axis integration, on-board MotionFusion™ and runtime calibration firmware, enables manufacturers to eliminate the costly and complicated selection, qualification and system-level integration of discrete devices, ensuring the best motion for consumers performance. MPU-60X0 is also designed to connect with multiple non-inertial digital sensors (such as pressure sensors) on its auxiliary I2C port. MPU-60X0 has a small footprint and is compatible with MPU-30X0 series. MPU-60X0 has three 16-bit analog-to-digital converters (ADC) to digitize the gyroscope output And three 16-bit ADCs for digital accelerometer output. For precise tracking of fast and slow speeds Movement, these parts have user-programmable gyroscope full-scale ranges ±250, ±500, ±1000 and ±2000°/sec (dps) and user-programmable accelerometer full-scale ranges are ±2g, ±4g, ±8g, and ±16g. The on-chip 1024-byte FIFO buffer allows the system processor to pass The sensor data is read in bursts, and then enters a low-power mode as the MPU collects more data. all Support many necessary on-chip processing and sensor components required for motion-based use Under the circumstances, MPU-60X0 uniquely supports low-power MotionInterface applications in portable applications, with Reduce the processing requirements of the system processor. By providing integrated MotionFusion output, The DMP in MPU-60X0 reduces the intensive MotionProcessing calculation requirements from The system processor minimizes the need to frequently poll the output of the motion sensor. Use 400kHz I2C or 1MHz SPI to perform communication with all registers of the device (MPU-6000 only). For applications that require faster communication, sensors and interrupt registers may Use 20MHz SPI to read (MPU-6000 only). Additional features include embedded temperature sensor And an on-chip oscillator with ±1% variation in the operating temperature range. By leveraging its patented and batch-proven Nasiri-Fabrication platform, which integrates MEMS wafers Through wafer-level bonding and supporting CMOS electronic devices, InvenSense drives the MPU-60X0 The package size is reduced to a revolutionary footprint of 4x4x0.9 mm (QFN) while providing the highest High performance, lowest noise and lowest cost semiconductor packaging required for handheld consumer electronics Electronic equipment. The part has a strong 10,000g shock resistance, and has a programmable low-pass Gyroscope, accelerometer, and on-chip temperature sensor filters. For power flexibility, MPU-60X0 works within the VDD power supply voltage range of 2.375V-3.46V. In addition, MPU-6050 also provides a VLOGIC reference pin (except its analog power pin: VDD), It sets the logic level of its I2C interface. The VLOGIC voltage can be 1.8V±5% or VDD. MPU-6000 and MPU-6050 are exactly the same, except that MPU-6050 only supports I2C serial interface. And there is a separate VLOGIC reference pin. MPU-6000 supports I2C and SPI interfaces, and has Single power supply pin VDD, it is not only the logic reference power supply of the device, but also the analog power supply of the device.
