AN98580
Migration from Macronix® MX25L to Cypress S25FL1-K SPI Flash Family
AN98580 provides migration guidelines for migrating from Macronix MX25L to Cypress S25FL1-K SPI Flash Families. The
discussions will focus on same density migrations, specifically the cases when migrating from the MX25L16 to S25FL116K,
from the MX25L32 to S25FL132K, and when migrating from the MX25L64 to the S25FL164K. Concerns regarding migration to
and from other densities can be extrapolated from the provided discussions.

1 Introduction
This application note provides migration guidelines for migrating from Macronix MX25L to Cypress S25FL1-K SPI
Flash Families.
The discussions will focus on same density migrations, specifically the cases when migrating from the MX25L16
to S25FL116K, from the MX25L32 to S25FL132K, and when migrating from the MX25L64 to the S25FL164K.
Concerns regarding migration to and from other densities can be extrapolated from the provided discussions.
The application note is based on information available to date from data sheets and other application notes
publicly available from Cypress and Macronix. Please also refer to the latest relevant specifications.
2 Feature Comparison
MX25L products are well suited for migrations to S25FL1-K products. Some of the reasons are compatible
pinouts, packages, command set, and 4/64 kB block/sector structure. Both product families support Dual I/O and
Quad I/O modes.
The major difference is the different OTP handling, which requires some SW changes when this feature is in use.
Please refer to the upcoming sections for more details regarding the other minor differences.

Packaging — All Densities
The most common packages for MX25L and S25FL1-K are the SOIC packages. The pinout is identical, thus, this
will allow a direct replacement without PCB redesign. Figure 1 shows those SOIC packages and pinouts. Please
refer to the data sheets for detailed package information.
