Product details
Overview
PN5110A0HN1/C2 from NXP Semiconductors is a 13.56 MHz contactless transceiver IC supporting ISO/IEC 14443A/Mifare, FeliCa, and NFCIP-1 protocols in Reader/Writer, Card Operation, and NFCIP-1 modes. It delivers up to 424 kbit/s bidirectional data transfer, integrates RF transmitter/receiver circuitry with TX1/TX2 outputs and RX input, and operates from a 2.5–3.6 V supply with hard power-down current ≤5 μA.
For engineers reviewing the PN5110A0HN1/C2 datasheet, PN5110A0HN1/C2 pinout, PN5110A0HN1/C2 application, or PN5110A0HN1/C2 equivalent, this page provides verified technical context for NFC reader design, secure access terminal integration, and multi-protocol contactless interface selection - including confirmed HVQFN32 package mapping, S2C interface support, CRC co-processor, and 64-byte FIFO buffer.
Technical Context
The PN5110A0HN1/C2 implements fully integrated analog front-end modulation/demodulation for ASK (100% and 8–30%) and load modulation schemes across all three operating modes. Its digital baseband handles ISO/IEC 14443A framing, FeliCa preamble/sync/CRC generation, and NFCIP-1 active/passive layer compliance - with internal CRC16 co-processor and parity logic.
It supports four host interfaces: SPI (up to 10 Mbit/s), I²C (Fast/High-speed modes), UART (RS232-level framing), and - unlike the HVQFN32 variant - explicitly excludes the 8-bit parallel interface per Table 14 and Pin Description Remark. The RF level detector and data mode detector enable automatic protocol detection and field presence sensing.

FAQ
What communication protocols does the PN5110A0HN1/C2 support?
The PN5110A0HN1/C2 supports ISO/IEC 14443A/Mifare, FeliCa, and NFCIP-1 protocols across three operating modes: Reader/Writer, Card Operation, and NFCIP-1. It handles full physical layer modulation/demodulation and baseband framing - including Modified Miller, Manchester, and BPSK coding - with hardware CRC16 and parity generation. All protocol support is implemented in silicon; no external firmware is required for layer-1 compliance.
Does the PN5110A0HN1/C2 include an integrated oscillator?
Yes, the PN5110A0HN1/C2 includes an internal oscillator circuit compatible with a 27.12 MHz quartz crystal connected to OSCIN/OSCOUT pins. This oscillator generates the precise timing reference needed for 13.56 MHz RF carrier synthesis and digital baseband synchronization. No external clock generator or PLL is required - the crystal directly feeds the RF clock recovery and distribution network within the PN5110A0HN1/C2.
What is the maximum operating distance achievable with the PN5110A0HN1/C2 in Reader/Writer mode?
The typical operating distance for PN5110A0HN1/C2 in Reader/Writer mode is up to 50 mm for ISO/IEC 14443A/Mifare and FeliCa cards, and up to 100 mm in Card Operation mode - both dependent on antenna size, tuning, and power supply. These values assume a properly matched 40 Ω antenna per the PN511 Antenna and RF Design Guide. Performance degrades below 3 V supply voltage, as noted in the Quick Reference Data table.
Which host controller interfaces are supported by the PN5110A0HN1/C2?
The PN5110A0HN1/C2 supports SPI (up to 10 Mbit/s), I²C (Fast mode: 400 kbit/s; High-speed mode: 3.4 Mbit/s), and UART (RS232-level framing, up to 1.2288 Mbit/s). It does not support the 8-bit parallel interface - that capability is exclusive to the HVQFN40 variant (PN5110A0HN/C2). Interface selection is auto-detected at power-up based on pin states and initialization sequence.
What is the purpose of the S2C interface in the PN5110A0HN1/C2?
The S2C (Serial-to-Card) interface in PN5110A0HN1/C2 provides a dedicated digital path for communication with secure elements like SAMs or secure microcontrollers. It enables high-speed, low-latency data exchange between the transceiver and cryptographic co-processor - essential for Mifare Classic authentication and FeliCa key management. The S2C interface operates independently of the main host interface and supports transfer speeds above 424 kbit/s when used with external circuitry.
