* IAM-20685 mass production started in calendar year 2022
* Safety Manual and Part Approval documentation available upon request
* IAM-20685 ISO 26262 development compliance assessed by third-party consultancy company
TDK Corporation (TSE:6762) announces today the full-scale production of InvenSense IAM-20685, the smallest ASIL-B monolithic 6-axis MEMS IMU developed in compliance with ISO 26262 for ADAS and autonomous car systems.
The IAM-20685 supports a wide range of ADAS applications, including but not limited to automated parking, ADAS domain controller, and vision systems.
"Thanks to its 6-axis integration and its ASIL-B compliancy at the component level, the IAM-20685 simplifies automotive ADAS systems development, helping overcome weaknesses of other technologies," said Alberto Marinoni, Sr Director - Product Marketing Automotive at InvenSense, a TDK Group company. "The high level of performance and the smallest size in the market means the IAM-20685 is the best IMU to integrate in positioning, vision, and radar modules in order to enhance their performance when the satellites are not available, road vibrations are applied, and the tilt is unknown, respectively."
