06.21.23 - TDK expands SmartIndustrial™ product family with thermal stable IMU product for tilt and stabilization applications

  • IIM-20670 platform, a robust, highly stable 6-axis IMU with extended temperature range and high VRE performance
  • IIM-20670 is part of a family of 3-axis accelerometers and a 6-axis MEMS IMU supplementing the SmartIndustrial™ product line

June 21, 2023

TDK Corporation (TSE:6762) announces the expansion of the InvenSense SmartIndustrial™ sensor platform family with the introduction of the IIM-20670. The IIM-20670 features a robust monolithic 6-axis IMU, 3-axis accelerometer and 3-axis gyroscope, with proven shock robustness and capability to simultaneously measure all the six axes with a current consumption below 10 mA under all operating conditions. With its support for extended temperature range of -40 to 105Co, this new 6-axis IMU targets industrial applications that requires extreme stability over temperature and great vibration immunity.

The IIM-20670 calibrated over multiple temperature points and available in a compact QFN 4.5 x 4.5 x 1.1 mm3 form with wettable flanks that simplify inspection at the end of the assembly line. It also features programmable digital filters and a 10 MHz SPI interface where data integrity can be assessed by a CRC-based error-detecting code algorithm. The IIM-20670 contains an accelerometer thermal stability of 45 ug/C, an accelerometer bias repeatability of 1mg and a programmable output of 64G alongside with a tilt algorithm that outputs pitch and roll data over the full temperature range. These specifications allow the IIM-20670 to provide one of the most stable 6-axis tilt outputs in the industry making it ideal for applications that need robust, fast, and accurate tilt or stabilization performance such as 5G platform, Industrial tilt modules, industrial/agricultural drones, etc.

This new thermal stable IMU for industrial applications delivers:

  • Precise measurements enabled by highly stable IMU
  • Support for extended temperature range (-40° to 105°C)
  • 64g accelerometer output
  • Best in class accelerometer bias offset & repeatability
  • Strong vibration rectification performance
  • A comprehensive development and evaluation platform along with necessary software to enable quick-to-market development of customer systems

"With the introduction of this new thermally stable product, calibrated over temperature, TDK is helping the industrial market segments in need of best-in-class stability output," said Camilo Delgado, Director of Industrial Marketing at InvenSense, a TDK group company. "The new IIM-20670 continues the SmartIndustrial platform to enable our customers and partners ground-breaking family of products that improve end user experience with a broad choice of performance and costs."

TDK's IIM-20670 platform is available now for evaluation and available through distribution partners worldwide by end of July 2023. For more information or to request a sample, please visit or contact InvenSense Sales at [email protected].

TDK will be demonstrating the IIM-20670 six axis IMU at the upcoming Sensors Converge 2023, booth #992 at the Santa Clara Convention Center, June 20-23, 2023. TDK will present a full range of sensor system solutions targeted for applications across automotive, consumer, health, industrial, machine learning, robotics, and more across multiple TDK product brands: InvenSense, Micronas, Qeexo, and Trusted Positioning.
