Product description
Analogue MEMS Angular Rate Sensor
A first generation general-purpose, analogue MEMS angular rate sensor. Superceded by later generation MEMS gyros - see 'Alternative Products' below.
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.
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.
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.
