TDK Corporation announced the availability of a new line of automotive high-accuracy devices from InvenSense, a TDK group company.
- IAM-20680: With operating range of -40°C to 85°C, the smallest 6-axis automotive-qualified sensor is the industry’s only device featuring 16-bit accelerometers and 16-bit gyroscopes in a series production car today
- IAM-20680HP: High-performance version of the IAM-20680 with an operating range of -40°C to 105°C, high gyroscope and offset thermal stability, as well as pin, package, and register compatible with the IAM-20680
- IAM-20380: With operating range of -40°C to 85°C, the only automotive-qualified gyroscope fully compatible (pin, package, register, and software) with a 3-axis automotive accelerometer (IAM-20381) and an automotive-qualified 6-axis device (IAM-20680)
- IAM-20381: With operating range of -40°C to 85°C, the only automotive-qualified 3-axis accelerometer fully compatible (pin, package, register, and software) with a 3-axis automotive gyroscope (IAM-20380) and an automotive-qualified 6-axis device (IAM-20680)
TDK’s family of automotive solutions can help enhance the absolute position of a vehicle in GNSS- and GPS-denied environments, such as tunnels, parking garages, and urban canyons.
The IAM-20680 and IAM-20680HP are also designed into the new InvenSense Coursa Drive software solution, the world’s first inertial-aided positioning software solution for autonomous vehicle platform developers. Coursa Drive enhances inertial-only vehicle positioning to <0.2% of distance traveled, such levels are critical to maintaining decimeter lane-level vehicle positioning in challenging environments and delivers a cost-effective, vehicle-dead-reckoning accuracy software solution equivalent to high-end systems costing tens of thousands of dollars.
Main applications include navigational system aids for dead reckoning, automotive lift gate motion detection, car alarm, telematics, accurate location for vehicle-to-vehicle and infrastructure, and more.
Other features include:
- Automotive-qualified
- Gyroscope full-scale: ±250°/s, ±500°/s, ±1000°/s, ±2000°/s
- Accelerometer full-scale: ±2g, ±4g, ±8g, ±16g
- Embedded temperature sensor
- 16-bit output for accelerometer, gyroscope, and temperature sensor
- SPI & I²C serial interface
- 512-bit FIFO
- 16-pin LGA package (3mm x 3mm x 0.75mm)
