I’d like to use the W7500 for my project, and I want to prevent unauthorized people from reading/dumping the firmware that is stored in Flash. Many microcontrollers offer Flash security, where a fuse bit is set in order to lock read access to Flash memory via external pins (like ISP and debug interfaces). It’s not bulletproof, but it raises the barrier to entry for an attacker trying to gain access to the firmware, hopefully making it very difficult and/or expensive.
Does the W7500 have this kind of Flash memory security available? I read the W7500 datasheet and reference manual, but (if I understand correctly) I could only find information about locking pages of Flash against accidental internal reads and writes, but nothing about locking access from an attacker who wants to hook up a programmer to some pins and dump the contents of Flash.
Thanks for any insight you can provide!
