description: |
6-axis 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 2kB FIFO and 2 programmable interrupts with
ultra-low-power wake-on-motion support to minimize system power consumption.
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.
