Defined as one of the new key features Atmel's Atecc80a offers an "Intrusion Latch for External Tamper Switch or Power-on Chip Enablement".

Separating crypto-chips from their original carrier-devices is always about an intrusion path that is difficult to lock down. The intrusion latch sounds 

like a potential remedy for this problem. Is there existing any more detailed information about this key functionality? Was reading several times all

available documentation. The latch wasn't mentioned anywhere else.
