PN512

PN512 Full NFC frontend Rev. 5.3 — 17 March 2020 111353 Product data sheet COMPANY PUBLIC 1. General description PN512 is the most broadly adopted NFC frontend - powering more than 10 billion NFC transactions per year. It is a highly integrated NFC frontend for contactless communication at 13.56 MHz. This NFC frontend utilizes an outstanding modulation and demodulation concept completely integrated for different kinds of contactless communication methods and protocols at 13.56 MHz. The PN512 NFC frontend supports 4 different operating modes Reader/Writer mode supporting ISO/IEC 14443A/MIFARE and FeliCa scheme Reader/Writer mode supporting ISO/IEC 14443B Card Operation mode supporting ISO/IEC 14443A/MIFARE and FeliCa scheme NFCIP-1 mode Enabled in Reader/Writer mode for ISO/IEC 14443A/MIFARE, the PN512’s internal transmitter part is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443A/ MIFARE 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/IEC 14443A/MIFARE compatible cards and transponders. The digital part handles the complete ISO/IEC 14443A framing and error detection (Parity and CRC). Enabled in Reader/Writer mode for FeliCa, the PN512 NFC frontend supports the FeliCa communication scheme. The receiver part provides a robust and efficient implementation of the demodulation and decoding circuitry fo...
