MEMs sensor for safety-critical automotive applications

03-06-2020 | Murata | Automotive Technologies

Murata has developed a new single package MEMs 6DoF inertial sensor for safety-critical automotive applications. The SCHA600 sensor provides exceptional performance for ADAS and AD applications, giving centimetre-level accuracy regarding vehicle dynamics and position, to secure safe, robust and verified autonomous driving.


The device is a single package 6DoF component qualified to the AEC-Q100 standard. The device comprises advanced self-diagnostic features and is also compliant to ASIL-D level – the highest Automotive Safety Integrity Level. With an Allan variance down to 0.9-degree/h at room temperature and gyro RMS noise level below 0.007-degree/s, the sensor achieves best in class performance for automotive applications regarding bias stability and noise. The orthogonality of the measurement axis is calibrated at the company, saving systems integrators time and money on executing this process step themselves.


The series features extensive failsafe functions and error bits for diagnostics including internal reference signal monitoring, checksum techniques for verifying communication, and signal saturation/over-range detection. Its component-level dynamic cross-axis calibration enables better than 0.3-degree cross-axis error over temperature.


The component is provided in a SOIC housing body size 18.7mm x 8.5mm x 4.5mm (L x W x H) with 32 pins and has an operating temperature range of −40C to +110C.
