NXP Semiconductors CLRC661
The CLRC661 multiprotocol 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 15693 • Read/write mode supporting ICODE EPC UID/ EPC OTP • Read/write mode supporting ISO/IEC 18000-3 mode 3/ EPC Class-1 HF The CLRC661’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). The CLRC661 supports the communication of MIFARE Classic with 1K memory, MIFARE Classic with 4K memory, MIFARE Ultralight, MIFARE Ultralight C, MIFARE Plus, and MIFARE DESFire products.
