High-performance motion tracking device that provides enhanced automotive positioning, telematics and vision systems

Here’s presenting the InvenSense IAM-20680HP, a high-performance automotive monolithic 6-axis MotionTracking sensor platform for non-safety relevant automotive applications. It includes the IAM-20680HP IMU MEMS sensor and the DK-20680HP developer kit.

The IAM-20680HP combines a 3-axis gyroscope and a 3-axis accelerometer in a thin 3 x 3 x 0.75mm (16-pin LGA) package and is automotive qualified based on AEC-Q100 Grade 2. It shares pin-to-pin and register compatibility with the full automotive non-safety product families of IAM-20680 (6-axis IMU), IAM-20380 (3-axis gyroscope) and IAM-20381 (3-axis accelerometer).

Also featured is 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. Additionally, the IAM-20680HP provides industry-leading sensitivity tolerance and temperature stability in combination with proven high robustness by supporting 10,000g shock reliability.

The IAM-20680HP platform enhances a positioning system’s accuracy, enables advanced telematic features and stabilises vision system by delivering precise and reliable inertial data up to 105 degrees Celsius. It also provides:
⦁ Best-in-class low noise performance
⦁ On-chip 16-bit ADCs
⦁ A 3-axis gyroscope with a user-programmable full-scale range of ±250 dps to ±2000 dps
⦁ A 3-axis accelerometer with a 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, reducing production-line calibration requirements. The device features I2C and SPI serial interfaces and voltage operating range of 1.71V to 3.6V.
