Product short data sheet
8.1.1 ISO 14443A/Mifare reader/writer functionality
8.1 Reader/Writer mode
PN512 transceiver IC supports the following operating modes:
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.
Generally 3 Reader/Writer modes are supported. The PN512 can act as a reader/writer
for ISO 14443A/Mifare, ISO 14443B or FeliCa cards.
In the Reader/Writer mode the PN512 enables the communication to a contactless
ISO 14443A/Mifare, ISO 14443B or FeliCa card.
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.
