PN532/C1
Near Field Communication (NFC) controller
7.1.5.2 FeliCa Card operating mode
With appropriate firmware, the PN532 can handle the FeliCa protocol.
The following diagram describes the communication at the physical level. Table 11
describes the physical parameters.
7.1.6 Overall CIU block diagram
The PN532 supports different contactless communication modes. The CIU supports the
internal 80C51 for the different selected communication schemes such as Card Operation
mode, Reader/Writer Operating mode or NFCIP-1 mode up to 424 kbit/s. The CIU
generates bit- and byte-oriented framing and handles error detection according to these
different contactless protocols.
Higher transfer speeds up to 3.39 Mbit/s can be handled by the digital part of the CIU. To
modulate and demodulate the data an external circuit has to be connected to the
communication interface pins SIGIN/SIGOUT.
Remark: The size and tuning of the antenna have an important impact on the achievable
operating distance.
