IAM-20680HT

High-Temperature SmartAutomotive™ 6-Axis MotionTracking® MEMS Device for Automotive Applications

The IAM-20680HT is a Grade 2 (-40ºC to 105ºC) 6-axis MotionTracking device for Automotive non-safety applications that combines a 3-axis gyroscope and a 3-axis accelerometer in a thin 3 × 3 × 0.75 mm³ (16-pin LGA) package. 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. IAM-20680HT, with its 6-axis integration, enables manufacturers to eliminate the costly and complex selection, qualification, and system level integration of discrete devices, guaranteeing optimal motion performance.

The gyroscope has a programmable full-scale range of ±250 dps, ±500 dps, ±1000 dps, and ±2000 dps. The accelerometer has a user-programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g. Factory-calibrated initial sensitivity of both sensors reduces production-line calibration requirements.

Other industry-leading features include on-chip 16-bit ADCs, programmable digital filters, an embedded temperature sensor, and two programmable interrupts. The device features I²C and SPI serial interfaces, a VDD operating range of 1.71V to 3.6V, and a separate digital IO supply, VDDIO from 1.71 V to 3.6 V.

In-Vehicle Infotainment

High performance 6-axis IMUs enhance positioning systems when GPS/GNSS signal is not available or reliable. Gyroscope and accelerometer outputs are fused to determine vehicle position even in multi-level parking or tunnels.

The accelerometer enables crash detection which can trigger emergency calls, and the gyroscope allows for vehicle positioning and driving style analysis.

6-axis IMU sensors enable advanced features and deliver a superior user navigation experience.
