Hello together,
maybe someone knows which value should be written to the “MTP Program
Password” register to perform writing to the MTP memory? Since datasheet contains no information about this.
thanks in advance,
Aleksandr
Hello Aleksander,
You need to write first 0x95h, then 0x63h in the password register before activating the MTP Write bit.
After writing is done you can write any value in the password register to protect against accidental writing.

Hello Nicolas,
Thank you for the reply!
Do you mean that I can change password word for the second writing to the MTP memory? Or do you mean something different under: “After writing is done you can write any value in the password register to protect against accidental writing.” ?
Hello Aleksander,
No, you cannot change the password, it is fixed.
What I mean is that after you have written 0x95h followed by 0x63h in the password register, then the memory is not write-protected anymore, you can write into it any time you want without re-entering the password.
To protect it again, you need to write any value (different from the password) in the password register.
Hope this is clear,
Nicolas.
Hello Nicolas,
Thank you! Now is clear,
Aleksandr
