IAM-20380

High Performance Automotive Gyroscope

The IAM-20380 is a 3-axis gyroscope in a small 3 × 3 × 0.75 mm (16-pin LGA) package. It also features a 512-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-20380, with its 3-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. Factory-calibrated initial sensitivity reduces production-line calibration requirements.

Other industry-leading features include on-chip 16-bit ADCs, programmable digital filters, an embedded temperature sensor, and 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 1.71V to 3.6V.

IAM-20380 Applications

Dead Reckoning	Telematics	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.
