TDK Launches IAM-20680HV: A High-Performance, Cost-Effective Six-Axis IMU for Automotive Applications

Tokyo, Japan – TDK Corporation (TSE: 6762) announced the global availability of the InvenSense SmartAutomotive™ IAM-20680HV, a high-value six-axis Inertial Measurement Unit (IMU) designed for a wide range of in-cabin automotive applications. Built to withstand harsh conditions, this sensor maintains reliable performance at ambient temperatures up to +105 °C and endures environments reaching +125 °C.

The IAM-20680HV integrates a 3-axis gyroscope and a 3-axis accelerometer into a compact 3 x 3 x 0.75 mm³, 16-pin LGA package. It is fully pin- and register-compatible with other TDK SmartAutomotive™ MEMS sensors using LGA packages, ensuring design scalability and platform flexibility. An optional ±125 dps full-scale gyroscope range enables higher resolution, supporting smooth navigation and precise motion tracking.

This new addition complements TDK’s growing IMU portfolio, delivering an optimal balance between cost-efficiency and performance to meet the evolving needs of automotive applications that do not require safety-critical ASIL certification.

Offering industry-leading low noise, tight sensitivity tolerances, and high reliability, the IAM-20680HV enables engineers to enhance functionality across a broad set of applications including GNSS modules, HUDs, navigation systems, telematics units, door modules, and crash/event data recorders.

“In today’s fast-moving automotive sector, performance must go hand-in-hand with affordability,” said Alberto Marinoni, Senior Director of Automotive Product Marketing at InvenSense (a TDK Group company). “Our technology empowers Tier 1s and OEMs to create advanced solutions in cost-sensitive environments—without sacrificing quality or performance.”
