General description

The PN533 is a highly integrated transceiver module for contactless communication at

13.56 MHz based on the 80C51 microcontroller core. A dedicated ROM code is

implemented to handle different RF protocols.

1.1 RF protocols

The PN533 supports four main operating modes:

The PN533 hardware implements a demodulator and decoder for signals from

ISO/IEC 14443A compatible cards and transponders. The PN533 hardware handles the

complete ISO/IEC 14443A framing and error detection and upper layers of this protocol

(i.e. ISO/IEC 14443-4) are implemented in firmware.

The PN533 supports all MIFARE products (e.g. MIFARE crypto method). It supports

contactless communication using higher transfer speeds up to 848 kbit/s in both

directions.

The PN533 hardware supports layers 2 and 3 of the ISO/IEC 14443B Reader/Writer

communication scheme, except anticollision. Anticollision is implemented in firmware as

well as upper layers (i.e. ISO/IEC 14443-4).

The PN533 can demodulate and decode FeliCa coded signals. The PN533 handles the

FeliCa framing and error detection. It supports contactless communication using FeliCa

Higher transfer speeds up to 424 kbit/s in both directions.

Compliant to ECMA 340 and ISO/IEC 18092 NFCIP-1 Passive and Active communication

modes, the PN5331B3HN/C270 offers the possibility to communicate to another NFCIP-1

compliant device, at transfer speeds up to 424 kbit/s. The PN533 handles the complete

NFCIP-1 framing and error detection.

1.2 Interfaces

The PN533 supports USB 2.0 full speed interface (bus powered or host powered mode).
