The difference between FX32K and FS32K

[OliverTian]

Hello, 

     If the full P/N of FX32K and FS32K have the only difference on 'X' and 'S', these two chips could be pin-2-pin compatible on hardware. The only difference for SW should be taken care on the default value of SDID register. Detail of SDID could be checked on S32K1xx reference manual. 

    FX32K and FS32K use the same data sheet and reference manual.

if the only differnet is X and S, SDID should be exactly same since they are identical part, am I correct?

Inside the S32K-DS.pdf is attached an excel files with the Orderable Part Numbers for S32K microcontrollers, and as of Rev. 10, this file does NOT include any part number starting with FX32K.  This led to confusion and time consuming activities in my team. This information now seems stable enough to be added to the list and avoid further confusion.
