Hello,

 

In LPC43S70 AES key is stored in OTP region of memory. 

According to errata OTP.2 problem OTP region can change its value.

When programmed AES key change, the chip will be bricked.

In this region of memory also boot source can be programmed. 

When boot source change, also chip will be bricked.

Are above scenarios possible?

Best regards,
