ISO/IEC 14443 Type B and NFC Forum Type 4B
Yes, the RF430CL33xH devices are designed to use NFC Forum standards, including the NDEF record standards.
NFC tags use the NFC Data Exchange Format (NDEF) to store data within tags according to the NDEF standards. This allows any NFC-enabled devices to read the data from any NFC tag and interpret it. Most applications on NFC-enabled smartphones use NDEF when reading or writing data to NFC tags.
The recommended hardware for evaluation is the Dynamic Dual Interface NFC Transponder BoosterPack™ Plug-in Module.
No BoosterPack plug-in module with the RF430CL331H is available from TI as of this writing, but there are two methods to get the RF430CL331H on a BoosterPack plug-in module:
See TI example firmware projects in Section 4 and program the device with a firmware example that includes a predefined NDEF Text RTD message.
TI example firmware projects contain examples of different NDEF record types. For a general reference that can be applied for the RF430CL33xH devices, see the NFCLink Standalone firmware for card emulation. The NFC card emulation using the TRF7970A application report includes a link to the firmware. The header file containing the NDEF record examples is located at [installed path]/nfclink/source/headers/ndef_image.h.
For technical details or information about message types not demonstrated in TI example firmware, see the following NFC Forum specifications: Type 4 Tag Operation, NFC Data Exchange Format (NDEF), and Record Type Definition (RTD) for details about how format the capability container and payload data per the NFC Forum standards.
