3.3 Contactless interface unit
The NFC module supports various communication modes at different transfer speeds and
modulation schemes. The following chapters give more detailed overview of selected
communication modes.
1> Reader/Writer communication modes
Generally 5 reader/writer communication modes are supported:
PCD reader/writer for ISO/IEC 14443A/MIFARE
The transfer speed includes 106 kbit/s, 212 kbit/s, 424 kbit/s and 848 kbit/s.
PCD reader/writer for ISO/IEC 14443B
The transfer speed includes 106 kbit/s, 212 kbit/s, 424 kbit/s and 848 kbit/s.
PCD reader/writer for Jewel/Topaz tags
The transfer speed includes 106 kbit/s, 212 kbit/s, 424 kbit/s and 848 kbit/s.
PCD reader/writer for FeliCa cards
The transfer speed includes 212 kbit/s, 424 kbit/s.
VCD reader/writer for ISO/IEC 15693/ICODE
The transfer speed includes 1.65 kbit/s, 26.48 kbit/s.
2> Peer to Peer communication modes
(ISO/IEC 18092, Ecma 340 NFCIP-1 communication modes)
An NFCIP-1 communication takes place between 2 devices:
NFC initiator: generates RF field at 13.56 MHz and starts the NFCIP-1communication.
NFC Target: responds to NFC 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.
The NFCIP-1 communication differentiates between Active and Passive communication
modes.
Active communication mode means both the NFC initiator and the NFC target are using their own RF field
to transmit data
Passive communication mode means that the NFC target answers to an NFC initiator command in a load
modulation scheme. The NFC initiator is active is terms of generating the RF field.
The NFC module supports the Active Target, Active Initiator, Passive Target and Passive
Initiator communication modes at the transfer speeds 106 kbit/s, 212 kbit/s and 424 kbit/s.
3> Card communication modes
The NFC module can be addressed as an ISO/IEC 14443A or ISO/IEC 14443B cards. This
means that NFC module can generate an answer in a load modulation scheme.
The transfer speed includes 106 kbit/s, 212 kbit/s and 424 kbit/s.
