IAM-20380HT high temperature automotive 3-Axis MotionTracking™ gyroscope developed for non-safety automotive applications
Provides accurate angular-rate sensing across an operating temperature range from -40 °C to 105 °C
Based on TDK's reliable MEMS technology proven by several million of units already in the automotive market
Pin-to-pin and register compatible with the whole TDK SmartAutomotive™ non-safety family
Automotive-qualified based on AEC-Q100 grade 2 test methods

SAN JOSE, Calif. , Nov. 15, 2022 /CNW/ -- TDK Corporation (TSE: 6762) extends the SmartAutomotive™ line of ASIL and non-ASIL motion sensors and announces the availability of InvenSense IAM-20380HT high temperature automotive monolithic 3-axis MotionTracking sensor platform solution for non-safety automotive applications, which includes the IAM-20380HT 3-axis MEMS gyroscope and the DK-20380HT developer kit.

IAM-20380HT is a stand-alone gyroscope in a thin 3 x 3 x 0.75 mm (16-pin LGA) package that can operate over a wide temperature range, delivering reliable and highly accurate measurement data for a variety of automotive non-safety applications including, but not limited to: navigation & dead reckoning, vehicle tracking, telematics, door control, and vision systems.

Leveraging on TDK's MEMS sensor fabrication technology, the IAM-20380HT, like all products belonging to the SmartAutomotive™ family, is a monolithic system-on-chip device that eliminates the wire bonding interconnections between the sensing element (MEMS) and the electronic front-end (CMOS) with unparalleled benefits in terms of performance and reliability.

"With the introduction of IAM-20380HT, TDK further expands its SmartAutomotive™ family and its leadership into the Automotive market, pursuing its commitment to enrich lives through smart sensing solutions," said Alberto Marinoni, Sr Director Product Marketing Automotive at InvenSense, a TDK Group company. "Thanks to TDK's expertise in high performance inertial sensors design and its products compliancy to RoHS without exceptions, IAM-20380HT pushes highly automated driving systems to the next level, enhancing user experience and making vehicles smarter and greener."

IAM-20380HT provides best-in-class low noise performance with leading bias instability to guarantee accurate vehicle location, on-chip 16-bit ADCs, and industry-leading sensitivity tolerance. Compared to previous generation 3-axis gyroscopes, it offers extended FIFO depth up to 4096-byte and two independent programmable interrupts.

The InvenSense IAM-20380HT automotive IMU is available from multiple distributors worldwide and is part of a fully compatible, multi-axis, multi-grade IMU portfolio of SmartAutomotive products reinforcing InvenSense's undisputed leadership in the 3-axis and 6-axis IMU market for both safety and non-safety automotive applications.
