# PN5321A3HN/C106,51 (Component)

## Description

High\-Performance NFC Controller with Integrated Reader/Writer and Peer\-to\-Peer Support – 13\.56 MHz NFC and RFID controller IC designed for contactless payment terminals, access control systems, smart card readers, ticketing, IoT devices, consumer electronics, and embedded NFC applications\. Supports NFC Forum standards, ISO/IEC 14443 Type A/B, FeliCa, MIFARE®, and NFCIP\-1 \(ISO/IEC 18092\), enabling reader/writer, peer\-to\-peer, and card emulation modes\. Features I²C, SPI, and High\-Speed UART \(HSU\) host interfaces, an integrated 80C51 microcontroller, 40 KB ROM, 1 KB RAM, and an RF front end with built\-in modulation/demodulation circuitry for simplified antenna design\. Operates from a 2\.7 V to 5\.5 V supply, supports data rates up to 424 kbps, and integrates CRC, parity checking, framing, and anti\-collision handling for reliable contactless communication\. Designed for surface\-mount assembly in a 40\-pin HVQFN \(6 × 6 mm\) package and operates over a −30°C to \+85°C temperature range\.
