Standalone gyroscope for non-safety automotive applications

New Products |
By Rich Pell


Electronic components and devices company TDK Corporation has announced the availability of a high-temperature automotive monolithic three-axis MotionTracking sensor platform solution for non-safety automotive applications. The InvenSense IAM-20380HT is a standalone gyroscope in a thin 3 x 3 x 0.75 mm (16-pin LGA) package that can operate over a wide temperature range and deliver reliable and highly accurate measurement data for a variety of automotive non-safety applications including, navigation & dead reckoning, vehicle tracking, telematics, door control, and vision systems.

It also features a 4096-byte FIFO that 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. The IAM-20380HT, says the company, with its three-axis integration, enables manufacturers to eliminate the costly and complex selection, qualification, and system level integration of discrete devices, guaranteeing optimal motion performance.

The IAM-20380HT is offered as providing 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 three-axis gyroscopes, it offers extended FIFO depth and two independent programmable interrupts.

Main features and benefits of the IAM-20380HT include:

  • Three-Axis Gyroscope
  • User-programmable full-scale range of ±250 dps, ±500 dps, ±1000 dps, ±2000 dps
  • Operating Temperature range from -40 °C to 105 °C
  • 16-bit on-chip ADC
  • Fully configurable ODRs and Power modes
  • User-programmable digital filters
  • Embedded Self-test
  • Two embedded configurable interrupt lines
  • Up to 4096-byte FIFO
  • Reliability testing performed according to AEC–Q100 Grade2
  • Final test over temperature

“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,” says 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.”
