ICM-42688-V Datasheet: High Precision 6-Axis MEMS MotionTracking™ Device with Advanced Sensor Fusion Library
■The ICM-42688-V SmartMotion™ sensor is a 6-axis MEMS MotionTracking device that combines a 3-axis gyroscope and a 3-axis accelerometer. It has a configurable host interface that supports I3C℠, I²C and SPI serial communication, features a 2 KB FIFO and 2 programmable interrupts with ultra-low-power wake-on-motion support to minimize system power consumption. It comes bundled with TDK’s Advanced Sensor Fusion Library that provides highly accurate sensor fusion outputs. This library is available on TDK’s Developer corner.
■ICM-42688-V supports highly accurate external clock input that reduces level sensitivity error, improves orientation measurement from gyroscope data, and reduces ODR sensitivity to temperature and device to device variation.
■The device includes industry-first 20-bits data format support in FIFO for high-data resolution. This FIFO format encapsulates 19-bits of gyroscope data and 18-bits of accelerometer data.
■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.
■The device supports a VDD operating range of 1.71V to 3.6V, and a separate digital IO supply, VDDIO from 1.71V to 3.6V.
