Triaxial Gyro from InvenSense
February 21, 2010
The MPU-3000 from InvenSense Inc., Sunnyvale, CA, is a triaxial MEMS gyroscope with an embedded digital motion processor (DMP) hardware accelerator engine. The 4 by 4 by 0.9 mm device features motion processing in smart phones for motions from 250°/s to >2000°/s, has built-in 16-bit ADCs, programmable digital filters, factory calibration to 1% sensitivity, built-in 6-axis sensor fusion, power consumption of 13 mW, and I2C and SPI interfaces. The DMP with an embedded FIFO offloads high-frequency motion algorithm computation from the host application processor, reducing interrupts and host MIPS to improve system performance.
