ICM-20948 - World’s Lowest Power 9-Axis MEMS MotionTracking™ Device

The ICM-20948 is the world’s lowest power 9-axis MotionTracking device that is ideally suited for Smartphones, Tablets, Wearable Sensors, and IoT applications.

  • 1/3 the power of existing 9-axis devices
  • 3-axis gyroscope, 3-axis accelerometer, 3-axis compass, and a Digital Motion Processor™ (DMPTM) in a 3x3x1mm (24-pin QFN) package
  • DMP offloads computation of motion processing algorithms from the host processor, improving system power performance
  • Software drivers are fully compliant with Google’s latest Android release
  • EIS FSYNC support

ICM-20948 supports an auxiliary I2C interface to external sensors, on-chip 16-bit ADCs, programmable digital filters, an embedded temperature sensor, and programmable interrupts. The device features an operating voltage range down to 1.71V. Communication ports include I 2C and high speed SPI at 7MHz.

There is a Development Kit available for the ICM-20948, and more information can be found here.
