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
