Inertial sensor with ASIL B (D) for semi-autonomous driving

Application & Technical Summary


SMI270 is a 6in1 inertial sensor with ASIL B (D) rating. The sensor is capable of measuring all 6 degrees of freedom: yaw/pitch/roll rate and acceleration in x/y/z directions.

Typical applications include L2 semi-autonomous driving, hands-free driving and positioning applications, and the integration into camera, radar, or lidar devices.

Product benefits
