4.4 Are authentication examples available for the TRF79xxA devices?

MIFARE Classic:

• The recommended authentication example requires either the TRF7970A or TRF7964A and is described in Using Special Direct Mode With the TRF7970A.
• Alternatively, the TRF79xxA devices covered in this guide can support MIFARE Classic tags by using Direct Mode 0 which requires the host MCU to run at a multiple of 13.56 MHz to encode and decode the raw subcarrier signal. The firmware example for this can be requested from http://www.ti.com/tool/TRF796X_TRF7970X_MIFARE_12_2013.

MIFARE DESFire AES authentication example is provided in MIFARE DESFire EV1 AES Authentication With TRF7970A. This example does not include example firmware for the exchange of encrypted data, only initial authentication with an AES key.
