NXP | CLRC66301HN,551

The CLRC66301HN,551 is a highly integrated transceiver IC for contactless communication at 13.56 MHz. It is available in HVQFN32 Package.

The CLRC663’s internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443A/MIFARE 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 CLRC663 supports MIFARE Classic 1K, MIFARE Classic 4K, MIFARE Ultralight,MIFARE Ultralight C, MIFARE PLUS and MIFARE DESFire products. The CLRC663 supports MIFARE higher transfer speeds of up to 848 kbit/s in both directions.
