How to use Tag Tamper loop feature of UCODE G2iL+ IC

[vaibhavpatel199]

We want to put RFID PCB tag in our new upcoming product for design this PCB antenna our PCB size is 5 mm width and 72 mm length. length can be adjustable +10 mm but width not possible to increase.

We want to use Tag Tamper Loop Feature of UCODE G2iL+ IC to set a tamper indicator will be set to 1 if PCB tampered by any cause.

Dear Kan,

The Table 37. states under pin tamper characteristics that resistance of <2 M-Ohm or >20 M-Ohm alters the tamper bit.  In my mathematics the M stands for Mega which would translate to 2.000.000 Ohm and 20.000.000 Ohm respectively. Is it a mistake? Shouldn't it be replaced by mili-Ohms with lowercase 'm'?

Regards,

Marcin

This bit flag by pin tamper write in definitive way to signaling the tamper status? Or in case to recobery the normal resistance it comes back to the normal value?
