IMU platform to enhance automotive application accuracy

InvenSense’s IAM-20680HP combines a three-axis gyroscope and a three-axis accelerometer in a thin 3x3x0.75mm (16-pin LGA) package and is automotive qualified based on AEC-Q100 Grade 2. The IAM-20680HP shares pin-to-pin and register compatibility with the full automotive non-safety product family from InvenSense: IAM-20680 (six-axis IMU), IAM-20380 (three-axis gyroscope) and IAM-20381 (three-axis accelerometer).

It also features an extended FIFO up to 4096-bytes 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 low-power mode. In addition, the IAM-20680HP provides sensitivity tolerance and temperature stability in combination with proven high robustness by supporting 10,000g shock reliability.

The IAM-20680HP platform is designed to enhance positioning systems accuracy, to enable advanced telematic features and to stabilise vision system by delivering precise and reliable inertial data up to 105°C. It also provides best-in-class low noise performance, on-chip 16-bit ADCs, a three-axis gyroscope with user-programmable full-scale range of ±250 dps to ±2000 dps, and a three-axis accelerometer with user-programmable full-scale range of ±2g to ±16g.

Other features include programmable digital filters, an embedded temperature sensor, programmable interrupts, and factory-calibration of both sensors, ultimately reducing production-line calibration requirements. The device features I2C and SPI serial interfaces and voltage operating range of 1.71V to 3.6V.

"TDK is the only company offering a fully compatible, multi-axis and multi-grade automotive IMU platform of products, designed to meet the increasing customer demand of platform scalability in automotive solutions," said Alberto Marinoni, Director of Product Marketing, Automotive at InvenSense. "Our unique and diversified portfolio helps customers scale their design from low-end to high-end solutions with minimal engineering effort, reducing R&D costs and accelerating time to market."
