MFRC631 High-performance ISO/IEC 14443 A/B frontend MFRC631 and MFRC631 plus Rev. 5.0 — 3 January 2024 Product data sheet 1 General description MFRC631, the cost efficient NFC frontend for payment. The MFRC631 multi-protocol NFC frontend IC supports the following operating modes: • Read/write mode supporting ISO/IEC 14443 type A and MIFARE Classic communication mode • Read/write mode supporting ISO/IEC 14443B The MFRC631’s internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443A and MIFARE Classic IC-based cards and transponders without additional active circuitry. The digital module manages the complete ISO/IEC 14443A framing and error detection functionality (parity and CRC).
