1. Introduction
1.1 Purpose and Scope
The PN532 is a highly integrated transmission module for contactless communication at
13.56 MHz including microcontroller functionality based on an 80C51 core with 40 Kbytes
of ROM and 1 Kbytes of RAM.
The PN532 combines a modulation and demodulation concept completely integrated for
different kinds of contactless communication methods and protocols at 13.56 MHz with
an easy-to-use firmware for the different supported modes and the required host
controller interfaces.
This document describes the firmware embedded in the PN532 chip, in particular the
global behavior in the system depending if the PN532 device is used as initiator or target.
1.2 Intended audience
This document has been written to allow the use of the PN532 from the host controller
point of view.
All the RF protocols used by the PN532 are not described in this document. The reader is
supposed to have knowledge on NFCIP-1 (Reference Error! Reference source not
found.) and ISO/IEC14443 (Reference Error! Reference source not found.).
