TRF7970A: NFC in Card Emulation Mode

Hello Ani,

the MSP430F2370 doesn't have enough code space for card emulation. The following document can give you more information and contains also a link to an example firmware:

For power consumption data please see the datasheet page 11 chapter 5.4:

Hello Helfried,

I am referring this document  from section 4 for my schematics and so I mentioned about MSP430f2370

if memory is quite less can I recreate with the above mentioned reference document by using MSP430F5529

Hello Ani,

That document is not for Card Emulation. That is for Reader mode for an ultra low power method to detect the presence of a Tag/Card as it is presented to the reader.

Hello Ralph,

Thanks for the quick response

So My application is Card Sniffing can I implement the same as in the document sloa184

For Implementing Card sniffer whether 2 Antennas (Loop Antenna and RF Test Port or External Antenna ) is required or single PCB Loop antenna is enough ?

Regards
