Product data sheet COMPANY PUBLIC Rev. 3.0 — 7 October 2016 240930 60 of 149 NXP Semiconductors PN5180 High-performance multi-protocol full NFC Forum-compliant frontend 4. An initiator shall only switch on its RF field if no external RF field is detected by the RF Level detector during a time of TIDT. (Details are specified in the ISO/IEC 18092) 5. The initiator performs initialization according to the selected mode. 11.8.1.7 ISO/IEC14443 A Card operation mode PN5180 can be configured to act as an ISO/IEC 14443 A compliant card. In this configuration, the PN5180 can generate an answer in a load modulation scheme according to the ISO/IEC 14443 A interface description. Note: PN5180 does not support a complete card protocol. This card protocol has to be handled by a connected host controller. Nevertheless, the layer3 type A activation is handled by the NFC frontend. The Card Activated IRQ shall be enabled and notifies if a card activation had been successfully performed. The supports ISO/IEC14443 A card mode for data rates 106 kbit/s, 212kbit/s, 424 kbit/s and 848 kbit/s. 11.8.1.8 NFC Configuration The NFC protocol for the 106 kbit/s mode defines an additional Sync-Byte (0xF0 + parity) after the normal start bit had been transmitted. As this Sync-Byte includes a parity bit, it can be handled by a host firmware as a normal data byte. 11.8.1.9 Mode Detector The Mode Detector is a functional block of the PN5180in PICC mode which senses for an RF field generated by another device. The mode detector allows distinguishing between type A and FeliCa target mode. Dependent on the recognized protocol generated by an initiator peer device the host is able to react. The PN5180 is able to emulate type A cards and peer to peer active target modes according to ISO/IEC18092. 11.8.2 RF-field handling The NFC frontend supports generation of a RF-field dependent on external conditions like presence of another NFC device generating an RF field. A flexible mechanism to control the RF field is available. Fig 28.
