Product data sheet
9.1.3 ISO/IEC 14443B reader/writer functionality
9.2 NFCIP-1 mode
The international standard ISO/IEC 14443 covers 2 communication schemes: the
ISO/IEC 14443A and the ISO/IEC 14443B.
The PN512 reader IC fully supports the ISO/IEC 14443.
The following registers and bits cover the ISO/IEC 14443B communication scheme:
As a reference documentation the international standard ISO/IEC 14443 'Identification
cards- Contactless integrated circuit(s) cards- Proximity cards, part 1-4' can be taken.
Note: NXP Semiconductors does not offer a software library to design in the
ISO/IEC 14443B protocol.
The NFCIP-1 communication differentiates between an active and a Passive
Communication mode.
In order to fully support the NFCIP-1 standard the PN512 supports the Active and Passive
Communication mode at the transfer speeds 106 kbit/s, 212 kbit/s and 424 kbit/s as
defined in the NFCIP-1 standard.

Active Communication mode means both the initiator and the target are using their
own RF field to transmit data.
Passive Communication mode means that the target answers to an initiator command
in a load modulation scheme. The initiator is active in terms of generating the RF field.
Initiator: generates RF field at 13.56 MHz and starts the NFCIP-1 communication
Target: responds to initiator command either in a load modulation scheme in Passive
Communication mode or using a self generated and self modulated RF field for Active
Communication mode.
