Inertial sensor with ASIL B for semi-autonomous driving (SMI270)
Application & Technical Summary
SMI270 is a 6in1 inertial sensor with ASIL B 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.
