Product Overview

The MPU-6880 is a 6-axis MotionTracking device that combines a 3-axis gyroscope, and a 3-axisaccelerometer in a small 3x3x0.9mm (24-pin QFN) package. It also features a 4096-byte FIFO that can lowerthe traffic on the serial bus interface, and reduce power consumption by allowing the system processor toburst read sensor data and then go into a low-power mode. With its dedicated I2C sensor bus, the MPU-6880directly accepts inputs from external I2C devices. MPU-6880, with its 6-axis integration, enablesmanufacturers to eliminate the costly and complex selection, qualification, and system level integration ofdiscrete devices, guaranteeing optimal motion performance for consumers. MPU-6880 is also designed tointerface with multiple non-inertial digital sensors, such as pressure sensors, on its auxiliary I2C port.The gyroscope has a programmable full-scale range of ±250, ±500, ±1000, and ±2000 degrees/sec. Theaccelerometer has a user-programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g. Factorycalibrated initial sensitivity of both sensors reduces production-line calibration requirements.Other industry-leading features include on-chip 16-bit ADCs, programmable digital filters, a precision clockwith 1% drift from -40°C to 85°C, an embedded temperature sensor, and programmable interrupts. Thedevice features I2C and SPI serial interfaces, a VDD operating range of 1.71 to 3.6V, and a separate digitalIO supply, VDDIO from 1.71V to 3.6V.Communication with all registers of the device is performed using either I2C at 400kHz or SPI at 1MHz. Forapplications requiring faster communications, the sensor and interrupt registers may be read using SPI at20MHz.By leveraging its patented and volume-proven Nasiri-Fabrication platform, which integrates MEMS waferswith companion CMOS electronics through wafer-level bonding, InvenSense has driven the package sizedown to a footprint and thickness of 3x3x0.9mm (24-pin QFN), to provide a very small yet high performancelow cost package. The device provides high robustness by supporting 10,000g shock reliability.
