    64 kB Low/High Parameter Block Erase Time of S25FL128L

    reca_4445166

      Hello, my name is Reynaldi, and I'm a hardware engineer in Aimvalley B.V. I'm looking for a drop-in replacement for the obsolescent S25FL129P which is used in a project in my company. I was considering both S25FL128S and S25FL128L for this purposes. However I found out that S25FL128S could not be used as a drop-in replacement as of the S25FL128S has a much slower Low/High Parameter Block Erase Time than the S25FL129P, which can be seen in the 64 kB Low/High Parameter Block Erase Time Test presented in the Cypress application note AN98577 "Migration from FL-P to FL-S Family SPI Interface Flash Memories", page 11, table 12.

       

      I am now exploring the possibilities of using the S25FL128L for this purpose instead. However I have not been able to find any results pertaining to Low/High Parameter Block Erase Time Test in the S25FL128L datasheet. Is this information available somewhere? I would like to ascertain whether the the FL-L devices suffer from the same issue as well or not. Thank you in advance.
