8. Operating modes

PN511 transceiver IC supports the following operating modes:

• Reader/Writer mode supporting ISO 14443A/Mifare and FeliCa scheme

• Card Operation mode supporting ISO 14443A/ Mifare and FeliCa scheme

• NFCIP-1 mode

The modes support different transfer speeds and modulation schemes. The following

chapters will explain the different modes in detail.

Note: All indicated modulation indices and modes in this chapter are system parameters.

This means that beside the IC settings a suitable antenna tuning is required to achieve the

optimum performance.

8.1 Reader/Writer mode

Generally 2 Reader/Writer modes are supported. The PN511 can act as a reader/writer for

ISO 14443A/Mifare or FeliCa cards.

Contactless Card

In the Reader/Writer mode the PN511 enables the communication to a contactless

ISO 14443A/Mifare or FeliCa card.

8.1.1 ISO 14443A/Mifare reader/writer functionality

The ISO 14443A/Mifare Reader/Writer mode is the general reader to card communication

scheme according to the ISO 14443A/Mifare specification.The following diagram

describes the communication on a physical level, the communication table describes the

physical parameters.
