2 FEATURES
2.1 GYROSCOPE FEATURES
The triple-axis MEMS gyroscope in the ICM-20948 includes the following features:
• Digital-output X-, Y-, and Z-axis angular rate sensors (gyroscopes) with a user-programmable full-scale range
of ±250 dps, ±500 dps, ±1000 dps, and ±2000 dps, and integrated 16-bit ADCs
• User-selectable ODR; User-selectable low pass filters
• Self-test
2.2 ACCELEROMETER FEATURES
The triple-axis MEMS accelerometer in ICM-20948 includes the following features:
• Digital-output X-, Y-, and Z-axis accelerometer with a programmable full scale range of ±2g, ±4g, ±8g, and
±16g, and integrated 16-bit ADCs
• User-selectable ODR; User-selectable low pass filters
• Wake-on-motion interrupt for low power operation of applications processor
• Self-test
2.3 MAGNETOMETER FEATURES
The triple-axis MEMS magnetometer in ICM-20948 includes a wide range of features:
• 3-axis silicon monolithic Hall-effect magnetic sensor with magnetic concentrator
• Wide dynamic measurement range and high resolution with lower current consumption.
• Output data resolution of 16-bits
• Full scale measurement range is ±4900 µT
• Self-test function with internal magnetic source to confirm magnetic sensor operation on end products
2.4 DMP FEATURES
The DMP in ICM-20948 includes the following capabilities:
• Offloads computation of motion processing algorithms from the host processor. The DMP can be used to
minimize power, simplify timing, simplify the software architecture, and save valuable MIPS on the host
processor for use in applications.
• The DMP enables ultra-low power run-time and background calibration of the accelerometer, gyroscope, and
compass, maintaining optimal performance of the sensor data for both physical and virtual sensors generated
through sensor fusion. This enables the best user experience for all sensor enabled applications for the
lifetime of the device.
• DMP features simplify the software architecture resulting in quicker time to market.
• DMP features are OS, Platform, and Architecture independent, supporting virtually any AP, MCU, or other
embedded architecture.
