Part Number: MSP430F6733

I’m looking for a simple yet effective way to protect the chip from being read/reverse engineered/modified.

  • Hi Eli,

    Would the JTAG security lock satisfy your request?

    Best regards

    Hi
    Tanks,but looking for solution without using the electronic fuse
  • In reply to eli:

    Hi Eli,

    Without enabling the eFuse, you can always access the device with JTAG and readout memory.
    What's your concern about the eFuse?

    Generally – yes. I just didn’t find the way to unlock that memory region using MSP-Gang programmer. If you have some examples, using programmer’s API – it would be appreciated.
  • In reply to eli:

    JTAG locking / unlocking can be done by your custom BSL, that will clear (write fore zero bytes) fuse area. Or by application itself. Overwrite 055h bytes to 000h on address 0FF80h.
