AN218107 Migration from S25FL-S to S25FL-L Serial NOR Flash Memory

The S25FL-S family is a 3.0-V Flash memory device based on the 65-nm MirrorBit process technology. The S25FL L family is a 3.0-V, single-supply (no VIO power supply), 4-KB uniform sector Flash memory device based on the 65-nm Floating Gate process technology. The S25FL-L family of Flash devices is the first Infineon product with uniform 4-KB sectors that also has performance and features that are comparable to the S25FL-S family of Flash devices. This document provides guidelines for migrating from the 128-Mbit and 256-Mbit densities of the S25FL-S and S25FL-L families by comparing and contrasting each feature in turn.
