TDK InvenSense ICM-42631

The ICM-42631 is the world's first triple-interface (UI + 2xOIS) 6-axis MEMS motion tracking device. It integrates a 3-axis gyroscope and a 3-axis accelerometer. It features a configurable host interface supporting I3C SM, I²C, and SPI serial communication, with 2KB FIFO and 2 programmable interrupts, and supports ultra-low-power motion wake-up to minimize system power consumption. The ICM-42631 supports the lowest gyroscope and accelerometer sensor noise in its IMU class, with the highest stability against temperature, shock (up to 20,000g), or SMT/flex-induced offset, while being immune to out-of-band vibration-induced noise. Additional features include the InvenSense on-chip APEX motion processing engine for gesture recognition, activity classification, and pedometer functions, as well as programmable digital filters and an embedded temperature sensor.
