Which contact smart card reader IC supports MIFARE DESFire?

I am looking for a smart card reader IC that both supports MIFARE DESFire (AES encryption) and is cost effective.

So far I considered CLRC663 but I was not able to locate in the datasheet, if AES encrypted communication with MIFARE DESFire smart cards is supported.

Hello Johannes Ritz,

The CLRC663 NFC frontend indeed supports the protocol to talk to MIFARE DESFire cards. However for the encrypted authentication part (AES encryption) you would need either a host MCU with a dedicated cryptoprocessor for the cryptographic operations or to use a MIFARE SAM AV2 IC in "X" mode (called SAM X-interface):

MIFARE SAMs for Reader Systems|NXP .

I recommend you to watch the next webinar to understand the general architecture of a NFC Reader and the operation with MIFARE ICs:
