TDK Launches High-performance 6-axis IMU with Industry-leading Motion Sensor Performance for IOT, Robotics, AR/VR and Wearable Applications

Key points:

1. External clock input improves system-level performance

2. 19-bit gyroscope resolution enhances slow-motion sensing accuracy

3. 2x increased temperature stability minimizes motion drift

4. 40% lower noise figure enhances sensor responsiveness

May 5, 2020——TDK Corporation announces the availability of the InvenSense ICM-42688-P high-performance motion sensor, a 6-axis MEMS MotionTracking™ device that combines a 3-axis gyroscope and a 3-axis accelerometer in a 2.5mm x 3mm x 0.9mm package. The device enables high-precision motion sensing applications such as robotics, wearable devices, drones, and many other IoT devices.

Compared to traditional consumer-grade IMUs, the ICM-42688-P 6-axis IMU provides a 40% lower noise figure and improves temperature stability by 2x, ensuring any motion event is measured with the highest accuracy, independent of temperature changes. The ICM-42688-P also includes two key innovations not available in any other consumer-grade IMU: a 100% accurate clock that eliminates timing errors and a high-resolution analog-to-digital converter. The converter enables an 8x increase in gyroscope resolution and a 4x increase in accelerometer resolution. Other industry-leading features include the InvenSense on-chip APEX Motion Processing Engine for gesture recognition, activity classification, and pedometer, along with programmable digital filters, and an embedded temperature sensor.

"It's all about performance, and TDK continues to deliver on that promise with best-in-class gyroscope stability vs. time and temperature, coupled with proprietary integrated technology for real-time response and content synchronization," said Amir Panush, InvenSense CEO and General Manager. " The ICM-42688-P is specifically designed with a focus on our tier-1 and channel customers, who care about high-precision, best-in-class sensors performance."

A comprehensive development platform, the DK-42688-P, along with necessary software is available to enable quick-to-market development of customer systems.

The DK-42688-P features:

Single Board "Out of the Box" experience

Comprehensive software tools to expedite evaluation and development

MotionLink™ and embedded motion driver (eMD)

On-board embedded developer tools to help with code development

15-minute setup time
