does ST25R3911B support ISO15693?

Hallo dear Community,

for a student projekt I am looking for a solution to communicate with M24LR04E-R which ist ISO15693 Dynamic Tag.

First I choose ST25R3911B-DISCO evaluation kit with ST25R3911B Reader-IC on it. This solution is ISO15693 compilant and it look‘s like a good idea to Read/Write on the M24LR. But it is in the developing phase and I can‘t order that.

So I thought about ordering simple ST25R3911B Reader-IC and upgrade it with a self-made antenna. But the datasheet of the ST25R3911B says nothing about  supporting NFC-V (ISO 15693).

Tell me please if I can pair ST25R3911B Reader-IC with

M24LR04E-R Tag

.

Best regards, Hanna

Hello Hanna,

The ST25R HF reader series provides multiprotocol support for 13.56 MHz NFC / RFID communications as ISO / IEC 14443 Type A or B, ISO / IEC 15693, ISO / IEC 18092, FeliCa and NFC Forum protocols.

Please refer to

http://www.st.com/en/nfc/st25-nfc-rfid-readers.html?querycriteria=productId=SC1540

The provided FW supports all tag products provided by ST. NDEF handling is not part of the current release of the discovery GUI.

We plan to release a new GUI version which will include a Tag Editor where NDEF formatting and handling is demo'ed.

Hth, and best regards,

Wolfgang

Hi Wolfgang,

I have the same question as Anna has: The product overview on the ST website clearly states that ST25R39xx devices support ISO / IEC 15693:

http://www.st.com/en/nfc/st25-nfc-rfid-readers.html

 

However, neither the product page, nor the datasheet mention ISO / IEC 15693:

http://www.st.com/content/st_com/en/products/nfc/st25-nfc-rfid-tags-readers/st25-nfc-rfid-readers/st25r3911b.html

 

http://www.st.com/resource/en/datasheet/st25r3911b.pdf

 They only refer to ISO 18092 (NFCIP-1) Active P2P, ISO14443A, ISO14443B and FeliCa.

On the other side, the GUI software for the ST25R3911B-DISCO works with ISO 15693. I have the demo board running.

Obviously, the ST25R3911B is capable of ISO / IEC 15693. But why is it not mentioned at all in the datasheet? Are there some issues we should be aware of?

Best regards,Michael

Hi Michael,

ST25R3911B does not directly support ISO15693. This protocol is only supported via the so called stream mode of ST25R3911B.

Bit coding/decoding, CRC, etc needs to be done in software.
