Description

The PN511 is a highly integrated transceiver IC for contactless communication at 13.56 MHz. This transceiver IC utilizes an outstanding modulation and demodulation concept completely integrated for different kinds of contactless communication methods and protocols at 13.56 MHz.

The PN511 transceiver ICs support 3 different operating modes
• Reader/Writer mode supporting ISO 14443A/Mifare and FeliCa scheme
• Card Operation mode supporting ISO 14443A/Mifare and FeliCa scheme
• NFCIP-1 mode

Enabled in Reader/Writer mode for ISO 14443A/Mifare, the PN511's internal transmitter part is able to drive a reader/writer antenna designed to communicate with ISO 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 14443A/Mifare compatible cards and transponders. The digital part handles the complete ISO 14443A framing and error detection (Parity & CRC).

The PN511 supports Mifare Classic (e.g. Mifare Standard) products. The PN511 supports contactless communication using Mifare higher transfer speeds up to 424 kbit/s in both directions.

Enabled in Reader/Writer mode for FeliCa, the PN511 transceiver IC supports the FeliCa communication scheme. The receiver part provides a robust and efficient implementation of the demodulation and decoding circuitry for FeliCa coded signals. The digital part handles the FeliCa framing and error detection like CRC. The PN511 supports contactless communication using FeliCa Higher transfer speeds up to 424 kbit/s in both directions. In Card Operation mode, the PN511 transceiver IC is able to answer to a reader/writer command either according to the FeliCa or ISO 14443A/Mifare card interface scheme. The PN511 generates the digital load modulated signals and in addition with an external circuit the answer can be sent back to the reader/writer. A complete card functionality is only possible in combination with a secure core IC using the S S2C interface.
