ICM-42670-P

High-Performance 6-Axis MotionTracking® IMU

The ICM-42670-P is a 6-axis MEMS MotionTracking device that combines a 3‑axis gyroscope and a 3‑axis accelerometer. This device is targeted at Consumer and IoT applications that require ultra-low power to drive longer battery lives. This sensor provides industry’s lowest power consumption for both 6‑axis and accelerometer only operating modes. It also comes with a list of embedded motion features and interrupts to further reduce system power consumption.

The ICM-42670-P combines a 3‑axis gyroscope and a 3‑axis accelerometer in a small 2.5 × 3 × 0.76 mm (14‑pin LGA) package. It also features up to a 2K Byte FIFO that can lower the traffic on the serial bus interface and reduce power consumption by allowing the system processor to burst read sensor data and then go into a low‑power mode.

It has a configurable host interface that supports I3C℠, I²C, and SPI serial communication, and two programmable interrupts with ultra low‑power wake‑on‑motion support to minimize system power consumption. Other industry‑leading features include on‑chip APEX Motion Processing engine for gesture recognition, and pedometer, along with programmable digital filters, and an embedded temperature sensor.

This product also comes with smaller Z‑height of 0.76 mm, making it suitable for form factor sensitive applications. Consumer products and systems with space constraints can leverage this 20% size reduction for their applications.

The ultra-low power consumption, small size, and on‑chip motion features makes it a perfect fit for applications such as wearables, hearables, AR glasses, smart home appliances, and TV remotes.

In addition, the ICM‑42670‑P supports the lowest gyro and accel sensor noise in this IMU class, and has the highest stability against temperature, shock (up to 20,000g) or SMT/bend induced offset as well as immunity against out‑of‑band vibration induced noise.

Hearables (TWS)

Wearables

AR Glasses

Detect Head Orientation for Spatial 360 audio accurately with the ultra-low power ICM-42670-P. This IMU also enables precise head gesture detection, in ear detection and activity monitoring at the lowest sensor power. Leverage the 20% size saving for small form-factor hearable devices.

Capture wrist gestures, fitness activities, exercise motion, sleep signatures and rehabilitation movements with high accuracy and lowest power consumption. Both medical and consumer wearables including smart watches, fitness bands and sports watches can leverage TDK’s ultra-low power sensor solution with on-chip motion features for an entire suite of wearable motion use cases.

Track head motion in AR glasses for navigation, gaming and entertainment with minimum latency and high accuracy. Leverage the high-performance features of ICM-42670-P to ensure a smooth user experience with no lag and accurate motion tracking. The low power sensor can benefit the AR battery driven applications.
