Description
The ICM-45687 is a high-performance dual interface (UI + AUX) 6-axis MEMS MotionTracking device. It has a configurable host interface that supports I3C℠, 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-45687 supports the lowest gyro and accel sensor noise in this IMU class, and has the highest stability against temperature, shock (up to 20,000 g) 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, along with programmable digital filters, and an embedded temperature sensor.
