The PN512’s contactless UART and dedicated external host must manage the complete
ISO/IEC 14443 A/MIFARE protocol.
according to ISO/IEC 14443 A/MIFARE.
The internal CRC coprocessor calculates the CRC value based on ISO/IEC 14443 A
part 3 and handles parity generation internally according to the transfer speed. Automatic
parity generation can be switched off using the ManualRCVReg register’s ParityDisable
bit.
The MFRC523 reader IC fully supports international standard ISO 14443 which includes
communication schemes ISO 14443 A and ISO 14443 B.
Refer to the ISO 14443 reference documents Identification cards - Contactless integrated
circuit cards - Proximity cards (parts 1 to 4).
Remark: NXP Semiconductors does not offer a software library to enable design-in of the
ISO 14443 B protocol.
