GENERAL DESCRIPTIONThe ICM-20948 is the world’s lowest power 9-axisMotionTracking device that is ideally suited for Smartphones,Tablets, Wearable Sensors, and IoT applications.• 3-axis gyroscope, 3-axis accelerometer, 3-axiscompass, and a Digital Motion Processor™ (DMPTM)in a 3 mm x 3 mm x 1 mm (24-pin QFN) package• DMP offloads computation of motion processingalgorithms from the host processor, improvingsystem power performance• Software drivers are fully compliant with Google’slatest Android release• EIS FSYNC supportICM-20948 supports an auxiliary I2C interface to externalsensors, on-chip 16-bit ADCs, programmable digital filters, anembedded temperature sensor, and programmableinterrupts. The device features an operating voltage rangedown to 1.71V. Communication ports include I2C and highspeed SPI at 7 MHz.Note: ICM-20948 VDDIO range is 1.71V to 1.95V, differentthan the MPU-9250 9-axis device.ORDERING INFORMATIONPART TEMP RANGE PACKAGEICM-20948† −40°C to +85°C 24-Pin QFN†Denotes RoHS and Green-Compliant PackageBLOCK DIAGRAMAPPLICATIONS• Smartphones and Tablets• Wearable Sensors• IoT ApplicationsFEATURES• Lowest Power 9-Axis Device at 2.5 mW• 3-Axis Gyroscope with Programmable FSR of±250 dps, ±500 dps, ±1000 dps, and ±2000 dps• 3-Axis Accelerometer with Programmable FSR of±2g, ±4g, ±8g, and ±16g• 3-Axis Compass with a wide range to ±4900 µT• Onboard Digital Motion Processor (DMP)• Android support• Auxiliary I2C interface for external sensors• On-Chip 16-bit ADCs and Programmable Filters• 7 MHz SPI or 400 kHz Fast Mode I²C• Digital-output temperature sensor• VDD operating range of 1.71V to 3.6V• MEMS structure hermetically sealed and bonded atwafer level• RoHS and Green compliantTYPICAL OPERATING CIRCUIT AUX_CL VDDIO SDO / AD0 REGOUT FSYNCINT1GNDSCL / SCLKnCSRESVVDDSDA / SDINC1.71 – 3.6VDCC2, 0.1 µFC3, 0.1 µ F1.71 – 1.95VDCSCLKSDIAUX_DASDOC1, 0.1 µ |
