TRF7963A: How to read/write Mifare M1 card

Part Number: TRF7963A
Other Parts Discussed in Thread: MSP430G2553, , TRF7964A, TRF7970A

Hello,

I am using MSP430G2553+TRF7963A to read/write Mifare M1(S50) card, origin code is sloc251.zip, now read NTAG213 OK,

is there any demo code about S50 card?

I find a package named TRF796X_TRF7970X_MIFARE_12_2013, it seems the right code I need, but not approved yet.

Is there more resource for reference?

Thanks.

Best Regards,
Howrd

    Hello Howard,

    For the TRF7963A that is your only option. Expect approval on Monday, though it could happen sooner.

    If you consider using the TRF7970A or TRF7964A you can refer to this example as these devices have Special Direct Mode functionality: www.ti.com/lit/an/sloa214/sloa214.pdf

    The Special Direct Mode method has much less MCU burden and a lower complexity (but it is still fairly complex compared to reading an NTAG 213).

    Also I am not 100% sure if the Mifare S50 is compatible with Mifare Classic, so if it is not then you may have extra development to do.
