The datasheet is often the same for N/Q/M variants, a table close to the
end mentions the differences. The intermediate letters have no useful
meaning for us and IIRC they number may vary. The meanging is:

        - W: Winbond
        - 25Q: SPI NOR family
        - 02J: Density
        - V: Voltage level
        - Useless information for software support such as the package
          size or some ratings which have no impact on the software, the
          absence of lead, etc.
        - And then there are subtleties such as features available or
          not, enabled by default or not, which can be disabled or not,
          that is carried by the last letter.

Thanks,
Miquèl
