NFC wireless interface supporting ISO14443 A and B on SMIC 180nm

The IP block provides the physical layer implementation of ISO 14443 interface. In particular, it includes the necessary functional devices for receiving data on the connected antenna, for the response load modulation, received and transmitted data (de)framing and parallel interface to external CPU.

This IP also can be used for adding NFC functionality to mobile devices and other applications to perform high-level RFID protocol tasks.

Extension of standards set and implementation of custom RFID protocols can be achieved by using direct access to all control signals of internal blocks.
