TM4C1231H6PZ: Permanently Lock EEPROM

Part Number: TM4C1231H6PZ

Hi team,

We are using the TM4C1231H6PZ in our application and are wondering if there is a way to permanently lock the EEPROM. I see that there are the EEPASSn registers to lock it but if an intruder knows the password, then the EEPROM will become available. Is there a way to have the EEPROM permanently locked?

Regards,

Akash Patel

    If you are concerned that the EEPROM contains a key or information that is crucial to keep private, yet must be accessed by the application, I suggest you disable debug. To enable debug on the part again you must go through the "Recovering a Locked Microcontroller" sequence which will erase all of the flash and eeprom before the part is unlocked.
