ICM-42688-V HIGHLIGHTS

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 I3CSM, 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.
