Heyho,

still checking L1 for new project, next question:

Are the L1's internal EEPROM register interface, erase, read, and write functions the same as on L0 (we're already using that) ?

Obrigado!

    Conclusion

    Yes, the internal EEPROM interface of STM32L0 and STM32L1 is fundamentally the same in terms of register-level access, reading/writing methodology, and control procedures. Minor differences may exist in timing and total EEPROM size based on specific MCU models, but porting code between L0 and L1 for EEPROM operations is generally seamless.
     
    ... so far good enough for me - compared with a quick RM-register comparison.

    Why don't you check it in the Reference Manuals for both chips?

    I guess the big question is, "Are there any Gotchas! which might be missed in reading the RM" ... ?

     

    The devil is often in the details ...

    If we choose the L1, I'll find out when using the L0 functions I have... :D
