This Near Field Communication (NFC) reference design provides a firmware example for the implementation of an NFC Card Emulation application using the TRF7970A NFC transceiver. This reference design provides a small number of easy to use Application Programming Interfaces (APIs) which allow users to quickly implement NFC Card Emulation functionality. The documentation, hardware, and example C code provided will allow designers to develop NFC Card Emulation applications with an MSP430 or easily ported to another MCU of choice. Sample Code described in this design can be downloaded from the design guide.

  • Proven interoperability with most commonly available NFC enabled devices
  • Supports the emulation of NDEF formatted RTD's for Type 4A and Type 4B Tag Platforms
  • Includes an easy to use GUI to select between individual NFC modes
  • Offers a flexible firmware structure that allows for configurable NDEF messages
  • Builds available for MSP-EXP430F5529 and MSP-EXP430F5529LP
  • This reference design is tested and includes firmware (with GUI), schematics, and User's Guide.
