Description
Product Description
The ICM-20948 is specifically designed to coordinate the time between the ICM-20948 and external sensors. An extra feature. In addition to using the module's dedicated interrupt INT pin, developers can use the external sensor's interrupt or sync pulse to drive the module's FSYNC pin to help developers simplify these multi-sensor designs. The ICM-20948 provides separate external sensors. 12C interface and built-in support. Developers here connect a 12C-compatible smart sensor to the module's dedicated auxiliary 12C port. While the SPI (or 12C) is connected to the host MCU, the developer can use the TDK tube to stream the InvenSense ICM-20948 module's auxiliary 12C interface (AUX_CL Connect external sensors to AUX_DA and manage them via the auxiliary device special registers of the lCM-20948. Features： Lowest Power 9-Axis Device at2.5 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 t16g 3-Axis Compass with a wide range to 4900 T Onboard Digital Motion Processor (DMP for Android support Auxiliary 2C interface for external sensors On-Chip 16-bitADCs and Programmable Filters 7 MHz SPI or 400 kHz Fast ModeIC Digital-output temperature sensor VDD operating range of 1.71V to3.6V MEMS structure hermetically sealed and bonded atwafer level Pins Definition： VCC: power terminal GND: Ground SCL: I2C serial clock interface SDA: I2C serial data interface NCS: used to read all data from the MPU and configure the MPU and external sensors ADO: SDO pin when using SPI INT: Interrupt pin FSY: related to the external sensor part ACL: Auxiliary 12C serial clock line ADA: Auxiliary 12C serial data line
