Product data sheet COMPANY PUBLIC Rev. 3.0 — 7 October 2016 240930 53 of 149 NXP Semiconductors PN5180 High-performance multi-protocol full NFC Forum-compliant frontend 11.8.1.2 ISO/IEC14443 B functionality The physical level of the communication is shown in Figure 21. The physical parameters are described in Table 53. The PN5180 requires the host to manage the ISO/IEC 14443 B protocol. 11.8.1.3 FeliCa RF functionality The FeliCa mode is the general reader/writer to card communication scheme according to the FeliCa specification. The communication on a physical level is shown in Figure 22. The physical parameters are described in Table 54. (1) Reader to Card NRZ, transfer speed 106 kbit/s to 848 kbit/s (2) Card to reader, Subcarrier Load Modulation Manchester Coded or BPSK, transfer speed 106 kbit/s to 848 kbit/s Fig 21.
