FAQs

  • CRS03
    • What do the suffixes 'R' and 'S' in the CRS03's part number mean?

      The CRS03 products have undergone three major changes during their lifetime.  The original products were NOT RoHS compliant and had no suffixes (eg CRS03-01, CRS03-04 etc).  An engineering product change to make them RoHS compliant resulted in the new part numbers with an 'R' suffix (eg CRS03-01R and CRS03-04R).  A later design change resulted from the change of ASIC supplier.  This caused no change to their specification but resulted in new part number variants with an 'S' suffix (eg CRS03-01S, CRS03-02S).  In 2016 Silicon Sensing made a change to the MEMS sensor fitted in the -01 and -02 versions of CRS03, and the new parts are identified with a ‘T’ suffix.  All previous CRS03 parts are now End of Life status.  CRS03-01T & -02T parts are RoHS compliant.

      My CRS03 gyro seems to have locked up

      On power-on, it is essential that the supply voltage ramps up to 4.75V within 500ms, otherewise the gyro output can freeze.  A similar problem can occur during a power supply drop-out.

      Do we need to be careful when designing my power supply for the CRS03 or other gyroscopes to make sure that the supply voltage ramps up at a certain rate?

      Yes.  For CRS03, the supply voltage must reach its nominal 5V in less than 5ms, otherwise the gyro may latch-up and will provide no output.  In this condition is does not automatically reset.
