TDK announces new 3-axis accelerometer, finalizing transition of SmartAutomotive™ non-safety product family to 105°C

• New: 3-axis MotionTracking^™ accelerometer for non-safety automotive applications
• Automotive qualified up to 105^°C based on AEC-Q100 grade 2
• Includes two independent interrupt lines and extended FIFO for reduced power consumption
• Pin-to-pin and register compatible across TDK's full line of inertial sensors

SAN JOSE, Calif., Jan. 9, 2024 /PRNewswire/ -- TDK Corporation (TSE:6762) today announced the InvenSense SmartAutomotive^™ IAM-20381HT high-temperature monolithic 3-axis MotionTracking accelerometer for non-safety automotive applications, such as navigation, infotainment systems, telematics, and more. The launch represents a full transition of the InvenSense SmartAutomotive non-safety product line to 105^°C.

The IAM-20381HT is part of a fully-compatible, multi-axis, multi-grade portfolio of SmartAutomotive products. With this release, TDK confirms its leadership in driving the inertial sensors market for both safety and non-safety automotive applications. The IAM-20381HT will be available at distributors worldwide by February 1, 2024.

"With this launch, TDK completes the transition from temperature grade 3 to grade 2 of the entire SmartAutomotive non-safety product line," said Alberto Marinoni, Senior Director Product Marketing Automotive at InvenSense, a TDK Group company. "Now TDK provides a complete lineup of pin-to-pin and register-compatible inertial sensors for automotive while ensuring scalability of customer applications up to 105^°C."

The new stand-alone 3-axis MEMS accelerometer is offered in a thin 3 x 3 x 0.75 mm (16-pin LGA) package and is automotive-qualified based on AEC-Q100 Grade 2. The IAM-20381HT also features two programmable independent interrupt lines, wake-on-motion functionality, and a FIFO up to 4096-bytes, which can lower the traffic on the serial bus interface and reduce power consumption by allowing the system processor to burst-read sensor data and then go into a low-power mode. Such features enable a variety of motion-activated functions such as anti-theft, vehicle security, and driving style data recording.

TDK will demonstrate this and other technologies at the Consumer Electronics Show (CES) from January 9-12, 2024, in Las Vegas. Find TDK in the CES Central Hall (LVCC) at booth #20521.
