TDK InvenSense ICM-45686

The ICM-45686 is a high-performance dual interface (UI + AUX) 6-axis MEMS MotionTracking device. It has a configurable host interface that supports I3CSM, I2C and SPI serial communication, and an AUX interface that supports SPI slave mode for connection to OIS controllers or I2C master mode for connection to external sensors. The device features up to 8Kbytes FIFO and 2 programmable interrupts. The ICM-45686 supports the lowest gyro and accel sensor noise in this IMU class, and has the highest stability against temperature, shock (up to 20,000g) or SMT/bend induced offset as well as immunity against out-of-band vibration induced noise. Other industry-leading features include InvenSense on-chip APEX Motion Processing engine for gesture recognition, activity classification, and pedometer, along with programmable digital filters, and an embedded temperature sensor.
