K81 NOR Flash - Micron vs Cypress

Because of shortages, we're replacing the Micron MT25QL128 NOR Flash Memory with what appears to be a pin-compatible and command-compatible Cypress S25FL128S.  (There are some command differences, but these commands are not used in the QSPI module).

 

Datasheets:

Micron MT25QL128 

Cypress S25FL128S

 

We are using a QSPI flash Module from NXP/Freescale (attached).  The commands implemented therein look like they should work without modification with the Cypress chip.   Is there anything else I should watch out for?

 

Thanks,

Denis
