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. Card interface mode supporting ISO 14443A / MIFARE® and FeliCa™ scheme NFCIP-1 mode Enabled in reader/ writer mode for ISO reader 14443A / MIFARE® and reader/writer mode for ISO 14443B, the PN532’s internal transmitter part is able to drive a reader/writer antenna designed to communicate with ISO14443A /MIFARE® and ISO14443B cards and transponders without additional active circuitry. The receiver part provides a robust and efficient implementation of a demodulation and decoding circuitry for signals from ISO 14443A / MIFARE® and ISO 14443B compatible cards and transponders. The digital part handles the complete ISO14443A framing and error detection (Parity & CRC). The PN532 supports MIFARE“ Classic (e.g. MIFAR...
