6. Software Considerations
Basic command set and 4-Byte command set of both flash families are similar. Status Register and Configuration
Register definitions are slightly different. Minor algorithm modifications may be necessary depending on your
application. The most common commands are the same as shown in Tables 6-1 and 6-2. Notable differences are
highlighted in blue in Table 6-3.

1.
MX66L51235F devices automatically clear the program or erase fail flags and do not have an explicit command to do so.
2.
MX66L51235F and S25FL512S devices share the same command opcode, but the command function is different.

Ver 1. May. 02, 2013
APPLICATION NOTE
6-1. Page Program Length Alignment
Page program maximum lengths are different between the MX66L51235F and the S25FL512S. 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 MX66L51235F has uniform 64KB blocks that are each subdivided into two 32KB blocks and sixteen 4KB
sectors. The S25FL512S has uniform 256KB blocks. Software adjustments are needed to accommodate the
smaller blocks provided by the MX66L51235F. Please refer to the datasheets listed in Section 9 for memory
organization details.
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 S25FL512S 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 MX66L51235F 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 MX66L51235F 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 S25FL512S and the MX66L51235F use Status Register BP (Block Protect) bits to software write protect
areas of memory. The S25FL512S only has three BP bits (BP2-BP0) and the granularity of the protected
areas is very large. The MX66L51235F 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.

APPLICATION NOTE
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 6-4, Table 6-5, and Table 6-6. If a detailed functional description of register bits is required,
please refer to the datasheets listed in Section 9.

7. Address Protocol Support
7-1. Addressing Memory Beyond 16MBytes
Both devices support various methods to address memory beyond 128Mb (16MBytes). Some of the methods
employed are different, but the concepts are the same. Depending on the application, the software may require
minor modifications. Please refer to the datasheets listed in Section 9 for more details.
7-1-1. 4-Byte Address Mode
4-Byte Address mode uses the legacy command set but the address field is 4-Bytes instead of 3-Bytes. The
Macronix device uses the EN4B and EX4B commands to enter and exit 4-Byte address mode. On the
Spansion device, 4-Byte address mode is entered or exited by setting or clearing bit-7 in the Bank Address
Register (BAR). After making the mode selection, the appropriate number of address bytes (3-Byte or 4-Byte)
must be used for all commands that require an address argument (with the exception of the Read SFDP
command (5Ah), which always uses 3-Byte addressing).
7-1-2. Bank Address Mode
Bank Address Mode uses one or more of the low-order bits of a bank address register to supply address bits
A24 and above for legacy read, program, and erase commands that use 3-Byte addressing. The serial flash
internally appends the low-order bits from the bank address to the 3-Byte address to form an extended address.
This allows access to addresses beyond 128Mb while still using the legacy command set and 3-Byte
addressing. In Spansion devices the bank register is the BAR. In Macronix devices the bank address register is
the Extended Address Register (EAR).
7-1-3. 4-Byte Address Command Set
Both Macronix and Spansion devices support a 4-Byte Address Command Set which always uses 4-Bytes of
address, eliminating the need to enter or exit 4-Byte Address mode. The 4-Byte Address Command Set (see
Table 6-2) supplements the legacy 3-Byte command set.

8. Summary
The Macronix MX66L51235F and Spansion S25FL512S have similar commands, functions, and features.
Additionally, the supported package types have identical footprints and nearly identical pin out definitions.
Software modification may be needed to accommodate to differences in the page program size and the block
erase size. Additional software modification may be needed 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.
