Product details
Overview
CLRC66302HN,157 from NXP Semiconductors is a high-performance multi-protocol NFC frontend IC supporting ISO/IEC 14443A/B, FeliCa (JIS X 6319-4), ISO/IEC 15693, ISO/IEC 18000-3 mode 3, and P2P passive initiator mode per ISO/IEC 18092. It delivers up to 848 kbit/s transfer speed for MIFARE Classic, integrates 512-byte FIFO, and operates from 3.0 V to 5.5 V supply - used in secure access control readers requiring robust contactless card detection at up to 12 cm.
For engineers reviewing the CLRC66302HN,157 datasheet, CLRC66302HN,157 pinout, CLRC66302HN,157 application, or CLRC66302HN,157 equivalent, key selection considerations include its HVQFN32 package with wettable flanks (MSL1), support for SPI/I²C/UART host interfaces, hardware-accelerated MIFARE Classic encryption, low-power card detection (LPCD), and dedicated SAM interface for secure key storage.
Technical Context
The CLRC66302HN,157 implements dual transmitter outputs (TX1/TX2) and differential receiver inputs (RXP/RXN) for optimized 13.56 MHz RF front-end performance, with integrated PLL deriving system clock from a 27.12 MHz crystal. Its analog interface handles full ASK modulation and subcarrier load modulation demodulation for ISO/IEC 14443A/B and FeliCa protocols.
Digital functionality includes a dedicated contactless UART managing protocol framing and CRC/parity error detection, a 512-byte FIFO buffer enabling high-throughput transactions, and five programmable timers - including Timer4 driven by an internal LFO for wake-up and low-power card detection - all controllable via register bank configuration.
Key Specifications
