ICM-456xy

Ultra High-Performance 6‑Axis MEMS Motion Sensor

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.

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) interfaces), up to 8 KB FIFO and 2 programmable interrupts.
