TRF7970A: P1060898（TRF7970ARHBR）NFC test fail FA require

你好Qin,

Is my understanding correct that you cannot either read nor write via NFC?

How many devices fail with these symptoms?

Did you do a curve trace to check for a leakage?

Or did you check if the general current consumption increased for this component?

Please provide the laser marking of the suspicious IC.

Thanks in advance & best regards

Hello Fu Qin,

Please excuse the delay due to public holidays. This seems to be something that cannot be solved ad-hoc here in the forum. Please open an official case @ https://www.ti.com/productreturns/docs/createReturn.tsp by entering all relevant data there. Shipping address and other relevant data will be handled there.

Thanks again for your inputs so far!
