6. Software Considerations
Basic command sets of both flash families are similar. Status Register and Security Register
definitions may be slightly different, but the concepts are the same. Minor modifications to the
algorithm may be necessary depending on application. See the Macronix datasheet for a
complete list of commands, as additional features may be available but are not shown.

6-2. Status Register and Security Register
Both devices use registers for providing status and setting device configuration, but there are some
differences that designers need to be aware of as modifications to software may be needed. Register
comparisons are shown in Table 6-2 and Table 6-3. If a detailed functional description of register bits is
required, please refer to the datasheets listed in section 8.

6-3. Manufacturer ID and Device ID
Manufacturer IDs are different. This permits software to identify the device manufacturer. The
Device IDs are different between both families. The same command is used to read the different

7. Summary
The Macronix MX25L_06E and Atmel AT25DF_A have similar commands, functions, and
features. Additionally, the supported package types have identical footprints and nearly identical
pinout definitions. A more detailed analysis should be done if any of the “special” functions not
supported by the Macronix flash are used, such as the Atmel 32KB erase size, or the Individual
Block Protection. Commands to access and program the OTP area are different as well. If
common features are used in standard traditional modes, the comparing may need only minimal
software modification.
