IIM-20670 platform, a robust, highly stable 6-axis IMU with an 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

TDK Corporation 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 a 3-axis gyroscope, with proven shock robustness and capability to simultaneously measure all six axes with a current consumption below 10mA under all operating conditions. With its support for an extended temperature range of -40 to 105℃, this new 6-axis IMU targets industrial applications that require extreme stability over temperature and great vibration immunity.

The IIM-20670 is calibrated over multiple temperature points and available in a compact QFN 4.5x4.5x1.1mm³ 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 45μg/C, an accelerometer bias repeatability of 1mg, and a programmable output of 64G alongside 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 platforms, 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℃)

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.”
