1. MX25L12835F devices automatically clear the program or erase fail flags and do not have an explicit command to do
so.

Ver.1, Apr. 15, 2013
APPLICATION NOTE
Comparing Spansion® S25FL128S with Macronix MX25L12835F
6-1. Page Program Length Alignment
The MX25L12835F and Hybrid Sector S25FL128S share the same 256-Byte maximum Page Program
length. However the Uniform Sector S25FL128S has a 512-Byte Page Program length. Software
modification is necessary if the longer page program length is being used. The Page Program length
should be set to a maximum of 256 bytes and the 1 to 256 bytes to be programmed must fall within the
same 256-Byte page boundary.
6-2. Sector Sizes
The MX25L12835F has uniform 64KB blocks that are each subdivided into two 32KB blocks and
sixteen 4KB sectors. The S25FL128S is offered in either Hybrid Sector Structure (a hybrid mix of
non-overlapping 4KB parameter sectors and 64KB main blocks) or Uniform Sector Structure (uniform
256KB blocks). Please refer to the datasheets listed in Section 8 for memory organization details.
For Spansion Hybrid Sector devices, no software adjustment will be required. The MX25L12835F
sector and block organization is a superset of the Spansion hybrid memory organization and can
match sector for sector and block for block. Spansion devices using uniform 256KB blocks will require
software adjustments to accommodate the smaller blocks provided by the MX25L12835F.
6-3. Secure OTP Differences
Both device families provide a secure One Time Programmable (OTP) area outside of the main
memory array for user defined storage. The sizes, features, and access methods are different.
The S25FL128S has commands to directly read (OTPR) and program (OTPW) the OTP area and
does not need to explicitly open this area for read and write operations.
The MX25L12835F operates in the OTP area using normal read and program instructions after
explicitly opening the OTP area with the Enter Secured OTP (ENSO) command. While the OTP area
is open, the main array is not accessible. When finished in the OTP area, the Exit Secure OTP (EXSO)
command must be issued to return to the Read Main Array mode. The MX25L12835F OTP area has
512 bytes available for user data. The user may permanently lock the whole OTP area to prevent new
data from being stored there. This area can optionally be programmed with user supplied data and
factory locked by Macronix.

6-4. Block Protection Mode
The S25FL128S and MX25L12835F use Status Register BP (Block Protect) bits to software write
protect areas of memory. The S25FL128S only has three BP bits (BP2-BP0) and the granularity of the
protected areas is very large. The MX25L12835F uses four BP bits (BP3-BP0) and provides a finer
protection area granularity.
6-5. Advanced Sector Protection Mode
Both device families offer an Advanced Sector Protection mode used to provide volatile and
nonvolatile individual sector (or block) protection and an optional password protection mode,
but there are differences that need to be accommodated if this feature is used.
6-6 Status Register, Configuration Register, and Security Register
Both devices use registers to configure the flash for operation modes, but there are some differences
that designers need to be aware of as software modifications may be needed. A detailed register
comparison is shown in Table 6-3, Table 6-4, and Table 6-5. If a detailed functional description of
register bits is required, please refer to the datasheets listed in Section 8.

7. Summary
The Macronix MX25L12835F and Spansion S25FL128S have similar commands, functions, and
features. Additionally, the supported package types have identical footprints and nearly identical pin
out definitions. If common features are used in standard traditional modes, they may need only
minimal software modification due to differences in status and configuration register bit assignments
and the commands used to access them. A more detailed analysis should be done if functions such
as Advanced Sector Protection, HOLD# pin, VIO voltage, DDR, or AutoBoot are used.
