Product details
Overview
MFRC63102HN,518 from NXP Semiconductors is a high-performance ISO/IEC 14443 A/B and MIFARE Classic frontend IC for contactless reader systems. It supports read/write modes for ISO/IEC 14443-A (including MIFARE Classic 1K/4K, Ultralight, DESFire EV1/EV2, Plus), ISO/IEC 14443-B, and achieves bidirectional data transfer up to 848 kbit/s. Its integrated transmitter drives 13.56 MHz antennas without external active circuitry and includes hardware-accelerated MIFARE Classic encryption - deployed in payment terminals, access control readers, and industrial NFC gateways.
For engineers reviewing the MFRC63102HN,518 datasheet, MFRC63102HN,518 pinout, MFRC63102HN,518 application, or MFRC63102HN,518 equivalent, key selection considerations include its 3.0–5.5 V supply range, HVQFN32 package with wettable flanks, 512-byte FIFO buffer, low-power card detection (LPCD) capability, and dual I²C interfaces - one for host, one dedicated to Secure Access Module (SAM) integration.
Technical Context
The MFRC63102HN,518 implements a full analog front-end for 13.56 MHz contactless communication, including dual TX outputs (TX1/TX2), differential RX inputs (RXP/RXN), and internal VMID reference generation. Its digital core integrates a CRC coprocessor compliant with ISO/IEC 14443-A Part 3, parity logic for 106–848 kbit/s framing, and a 512-byte FIFO for high-throughput transaction handling.
It features five programmable timers (Timer0–Timer4), with Timer4 serving as a wakeup timer driven by an internal LFO for low-power card detection. Host interface auto-detection is performed via IFSEL0/IFSEL1 pins, supporting SPI (up to 10 Mbit/s), UART (RS232-level, up to 1228.8 kBd), and two I²C variants (I²C and I²CL, up to 1000 kBd in Fast Mode Plus).
Key Specifications

Pinout & Package
MFRC63102HN,518 is housed in a 5 mm × 5 mm × 0.85 mm HVQFN32 package (SOT617-1) with wettable flanks and a central thermal pad (VSS, Pin 33) for enhanced thermal dissipation in compact reader designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TX1 / TX2 | RF Transmitter Outputs | Deliver modulated 13.56 MHz carrier to antenna network; support differential or single-ended antenna drive configurations. |
| RXP / RXN | Differential RF Receiver Inputs | Accept demodulated subcarrier signals from antenna; enable high-noise-immunity reception per ISO/IEC 14443 physical layer. |
| VDD / PVDD / TVDD | Power Supply Rails | VDD powers digital core (3.0–5.5 V); PVDD supplies pad drivers; TVDD powers transmitter stage - allows independent voltage optimization. |
| IF0–IF3, IFSEL0/IFSEL1 | Host Interface Configuration | Determine active host interface (SPI/I²C/UART) at power-up via hardwired logic levels - eliminates firmware configuration overhead. |
| SCL / SDA | Primary I²C Bus | Supports host MCU communication up to 1000 kBd (Fast Mode Plus); separate from SAM interface for concurrent secure operations. |
| IRQ | Interrupt Request Output | Signals frame completion (TxIRQ/RxIRQ), timer underflow, FIFO alerts, or card detection (LPCDIRQ) - enables event-driven host firmware. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC frontend applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MFRC63103HN | Wider supply range (2.5–5.5 V), enhanced LPCD register (LPCD_OPTIONS), and improved load protocol settings for small antennas. | Better suited for space-constrained or battery-operated designs requiring flexible low-voltage operation and optimized small-antenna tuning. | Select MFRC63103HN for new designs where extended voltage range or advanced LPCD configurability is required. |

FAQ
What is the primary function of the MFRC63102HN,518 in an NFC reader system?
The MFRC63102HN,518 serves as a dedicated ISO/IEC 14443-A/B and MIFARE Classic frontend IC. It handles all physical-layer RF tasks - including 13.56 MHz modulation/demodulation, CRC calculation, parity generation, framing, and hardware-accelerated MIFARE Classic encryption - while interfacing with an external host MCU via SPI, I²C, or UART. It does not execute higher-layer protocols like ISO/IEC 7816 or NFC Forum specifications; those remain the responsibility of the host.
Does the MFRC63102HN,518 support ISO/IEC 14443-B anticollision?
No, the MFRC63102HN,518 does not implement ISO/IEC 14443-B anticollision in hardware. Per the official datasheet, anticollision must be implemented in the host controller's firmware, along with upper-layer protocol handling. The MFRC63102HN,518 provides only layers 2 and 3 of the ISO/IEC 14443-B reader/writer communication scheme - physical signaling, SOF/EOF detection, and basic framing - leaving anticollision and command sequencing to the host MCU.
What is the role of the separate I²C interface on the MFRC63102HN,518?
The MFRC63102HN,518 includes a dedicated I²C bus (pins SCL/SDA) exclusively for connecting a Secure Access Module (SAM). This interface operates independently from the primary host interface, enabling concurrent secure key storage, cryptographic operations (e.g., DES, AES, RSA), and session key derivation - essential for EMV contactless payment compliance. The SAM interface supports standard I²C timing and is electrically isolated from host traffic to prevent side-channel leakage.
Can the MFRC63102HN,518 operate with a 2.5 V supply?
No, the MFRC63102HN,518 requires a minimum supply voltage of 3.0 V on VDD, as confirmed in Table 1 of the datasheet. The 2.5 V minimum applies only to the MFRC63103HN variant (Table 2). Using 2.5 V on MFRC63102HN,518 will result in undefined behavior or failure to initialize, since its internal voltage regulators and analog front-end circuits are characterized and guaranteed only from 3.0 V onward.
How does the MFRC63102HN,518 achieve low-power card detection (LPCD)?
The MFRC63102HN,518 implements LPCD using Timer4 driven by the internal Low-Frequency Oscillator (LFO), which remains active during standby. It periodically samples receiver path activity (via RXP/RXN) and triggers the LPCDIRQ interrupt upon card presence detection. With power-down current as low as 8 nA and configurable sensitivity thresholds, it enables battery-powered readers to maintain card presence awareness for days or weeks without compromising responsiveness.
