This product is not recommended for new and current designs. For new and current designs, the S25FL256S supersedes S70FL256P. This is the factory-recommended migration path. Refer to the S25FL256S datasheet for specifications and ordering information, and AN98592 for changes required to migrate from existing designs based on S70FL256P.
