CLRC663

Hi,

I use CLRC663 in my project as MIFARE Reader & its cards/tags.

My code is working faithfully with MIFARE SAM AV3 evaluation board (MCU: ATSAM, SPI Based Comm.) for;

function: PICC_IsNewCardPresent() (includes; query: REQA/WUPA, response: ATQA)
Function: AntiColl_n_Sel() (includes; get SAK & UID)
Function: Authentication (includes; authentication & read (sector read faithfully done))

Now, if I try to do the same (all the above mentioned functions/stages) with my own designed board/PCB, I can’t receive ATQA!

I debug this issue and found that there is an issue with antenna circuit (not in antenna matching circuit), so I’ve replaced my antenna by MIFARE SAM AV3 evaluation board’s antenna. With this set-up (my MCU: ATSAM, My Antenna tuning circuit & MIFARE SAM AV3 evaluation board’s antenna), I can run the functions 1 (PICC_IsNewCardPresent()) & function 2 (AntiColl_n_Sel()) faithfully and getting UID also, but I can’t run the function (Authentication & read), there was an error flag set (in most cases: Error register (0x0A) has set CollDet & IntegErr) when I scan the MIFARE Card/tag.

Can anyone help me to resolve my issue?

Hi Chinmay

Just an information that SAM is secured by NDA (Non-Disclosure-Agreement), I would suggest you create a ticket to NXP technical support if you need help.
