The SCHA600 sensor supports ADAS and AD (automated driving) applications, offering centimetre-level accuracy in regard to vehicle dynamics and position, to ensure safe, robust and verified autonomous driving.
The SCHA600 is a single package 6DoF component qualified to the AEC-Q100 standard. It includes 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 °/h at room temperature and gyro RMS noise level below 0.007°/s, the sensor delivers improved levels of performance for automotive applications in regard to bias stability and noise.
The orthogonality of the measurement axis is calibrated at Murata, saving systems integrators time implementing this process step themselves.
The SCHA600 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° cross axis error over temperature.
The 3-axis accelerometer contains a continuously operating self-test function that monitors the sensor during measurement. This patented self-test function verifies the proper operation of the entire signal chain from MEMS sensor movement to signal conditioning circuitry for every measurement cycle.
The component is supplied in a SOIC housing body size 18.7 mm x 8.5 mm x 4.5 mm (L × W × H) with 32 pins and has an operating temperature range of −40°C - +110°C .
