PN532/C1 NFC controller Rev. 1.2 — 31 March 2011 Short form data sheet 1. Introduction This document describes the NFC controller PN532. This document is a short form version; for full specification refer to the product data sheet. 2. General description The PN532 is a highly integrated transmission module for contactless communication at 13.56 MHZ including micro-controller functionality based on an 80C51 core. The transmission module utilises an outstanding modulation and demodulation concept completely integrated for different kinds of passive contactless communication methods and protocols at 13.56 MHZ. The PN532 support 4 different operating modes: • Reader/writer mode supporting ISO 14443A / MIFARE® and FeliCa™ scheme • ISO 14443B in reader/writer mode only.
