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.
