Ultra High-Performance 6-Axis MEMS Motion Sensor

OVERVIEW

The ICM-456xy is an ultra-high-performance 6‑axis MEMS motion sensor family with the world’s first BalancedGyro™ technology and lowest power consumption. The sensor combines a 3‑axis gyroscope and a 3‑axis accelerometer in a compact 2.5 × 3 × 0.81 mm package.

The BalancedGyro technology by TDK is the first‑of‑its‑kind gyroscope MEMS architecture that enables supreme vibration rejection and temperature stability performance, an enhancement never seen before in a consumer gyroscope.

The ICM-456xy family also provides a new Self‑Calibration feature that allows sensitivity calibration to be done on-chip, leading to a 10x enhancement in the lifetime sensor accuracy of the gyroscope. This significantly reduces the overall rotational angle error especially for robotics and OIS applications.

This family also offers the world’s lowest power 6‑axis motion sensor. This allows the gyroscope to be on 40% of the times more than any other gyroscope in the industry. This makes it very suitable for wearable and hearable gesture and activity detection applications.

It has a configurable host interface that supports I3C℠, I²C, and SPI serial communication, triple interface (host interface + 2 Optical Image Stabilization (OIS) interface), up to 8 KB FIFO and 2 programmable interrupts.
