Icarvisions.com1.Introduction
MPU-60X0 is the world's first integrated 6-axis MotionTracking device. It integrates a 3-axis MEMS gyroscope, a 3-axis MEMS accelerometer, and an extensible digital motion processor DMP (Digital Motion Processor), which can be connected to a third-party digital sensor, such as a magnetometer, with an I2C interface. After expansion, it can output a 9-axis signal through its I2C or SPI interface (SPI interface is only available on MPU-6000). MPU-60X0 can also connect non-inertial digital sensors, such as pressure sensors, through its I2C interface.
The MPU-60X0 uses three 16-bit ADCs for the gyroscope and accelerometer, respectively, and converts the analog quantity it measures into a digital output. In order to accurately track fast and slow movements, the measurement range of the sensor is user-controllable, the gyro measurement range is ±250, ±500, ±1000, ±2000°/sec (dps), and the accelerometer measurement range It is ±2, ±4, ±8, ±16g.
An on-chip 1024-byte FIFO helps reduce system power consumption. Communication with all device registers uses 400kHz I2C interface or 1MHz SPI interface (SPI is only available for MPU-6000). For applications that require high-speed transmission, a 20MHz SPI can be used to read and interrupt registers. In addition, a temperature sensor and an oscillator with only ±1% variation in the working environment are embedded on the chip. The chip size is 4×4×0.9mm, using QFN package (leadless square package), which can withstand a maximum impact of 10000g, and has a programmable low-pass filter.
Regarding power supply, MPU-60X0 can support VDD range 2.5V±5%, 3.0V±5%, or 3.3V±5%. In addition, the MPU-6050 also has a VLOGIC pin, which is used to provide logic levels for the I2C output. The VLOGIC voltage can be 1.8±5% or VDD.
2. Features
