富威集團代理產線 Invensense 推出 Motion Sensor 解決方案

 2011-12-14

MPU-6000為全球首例整合3軸陀螺儀、3軸加速器、含9軸融合演算技術(sensor fusion)的運動處理組件

概述

MPU-6000為全球首例整合性6軸運動處理組件,相較於多組件方案,免除了組合陀螺儀與加速器時之軸間差的問題,減少了大量的包裝空間。MPU-6000整合了3軸陀螺儀、3軸加速器,並含可藉由第二個I2C端口連接其他廠牌之加速器、磁力傳感器、或其他傳感器的數位運動處理(DMP: Digital Motion Processor)硬體加速引擎,由主要I2C端口以單一數據流的形式,向應用端輸出完整的9軸融合演算技術。

InvenSense的運動處理資料庫,可處理運動感測的複雜數據,降低了運動處理運算對操作系統的負荷,並為應用開發提供架構化的API。

MPU-6000的角速度全格感測範圍為±250、±500、±1000與±2000°/sec (dps),可準確追蹤快速與慢速動作,並且,用戶可程式控制的加速器全格感測範圍為±2g、±4g±8g與±16g。產品傳輸可透過最高至400kHz的I2C或最高達20MHz的SPI。

MPU-6000可在不同電壓下工作,VDD供電電壓介為2.5V±5%、3.0V±5%或3.3V±5%,邏輯接口VVDIO供電為1.8V± 5%。MPU-6000的包裝尺寸4x4x0.9mm(QFN),在業界是革命性的尺寸。其他的特徵包含内建的温度感測器、包含在運作環境中僅有±1%變動的振盪器。
