Product details
Overview
MFRC52201HN1,115 from NXP Semiconductors is a contactless reader/writer IC for 13.56 MHz RFID systems supporting ISO/IEC 14443 A/MIFARE and NTAG protocols. It integrates analog front-end, digital baseband, CRC coprocessor, and 64-byte FIFO, enabling secure read/write operations with MIFARE Classic (1K/4K/Mini), DESFire EV1, Plus, and Ultralight cards in access control and payment terminals.
For engineers reviewing the MFRC52201HN1,115 datasheet, MFRC52201HN1,115 pinout, MFRC52201HN1,115 application, or MFRC52201HN1,115 equivalent, this device delivers verified 848 kBd transfer speed, 2.5–3.3 V operation, HVQFN32 package compatibility, and triple-host interface support (SPI up to 10 Mbit/s, I²C up to 3.4 Mbit/s, UART up to 1228.8 kBd) for embedded NFC frontend design.
Technical Context
The MFRC52201HN1,115 implements a fully integrated analog transceiver with TX1/TX2 modulated 13.56 MHz carrier outputs, internal oscillator for 27.12 MHz crystal, and RF signal input via RX pin. Its digital core handles ISO/IEC 14443 A framing, parity, and CRC-16 generation/check per Part 3, with automatic protocol detection across SPI, I²C, and UART interfaces.
It supports MFIN/MFOUT for external smart card power delivery, includes programmable timer and interrupt logic (IRQ output), and features hard/soft power-down modes with ≤10 µA current draw. The device operates across −25 °C to +85 °C ambient temperature in HVQFN32 (5 × 5 × 0.85 mm) package with thermal enhancement.

Pinout & Package
HVQFN32 (SOT617-1) package with 32 terminals, body size 5 × 5 × 0.85 mm, thermal-enhanced construction for stable RF performance in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TX1 / TX2 | Modulated RF carrier outputs | Drive external antenna matching network at 13.56 MHz; require impedance tuning to 40 Ω for optimal 50 mm read range. |
| RX | RF signal input | Receives demodulated subcarrier load-modulated signals from MIFARE/NTAG tags; connects directly to antenna receive path. |
| IRQ | Interrupt request output | Active-low signal indicating completed command, FIFO status, or error condition - enables event-driven host firmware. |
| NRSTPD | Reset and power-down input | Hard reset on rising edge; power-down mode when held LOW - reduces total current to ≤10 µA for standby operation. |
| MFIN / MFOUT | MIFARE smart card interface | Delivers regulated power (via SVDD) and bidirectional signaling to external MIFARE ICs - supports dual-interface card emulation. |
| SDA/NSS/RX, SCL/MISO/TX, etc. | Multi-function host interface pins | Shared pins auto-detected at power-on for SPI/I²C/UART - eliminates external configuration jumpers or strapping resistors. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated analog front-end | Eliminates need for external RF amplifiers, filters, or matching components - reduces BOM count and PCB area in NFC reader modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless reader IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN5120A01HN/C1 | Higher RF output power (+1 dBm), integrated EEPROM, supports ISO/IEC 14443 B and FeliCa - no MIFARE DESFire EV1 crypto acceleration. | Better suited for multi-standard readers requiring FeliCa or ISO-B compatibility; lacks native DESFire EV1 key management acceleration. | Select PN5120A01HN/C1 when expanding beyond MIFARE/NTAG to include FeliCa or ISO-B, and when on-chip EEPROM storage is needed for firmware or keys. |
| RC522 (clone variant) | Unlicensed silicon implementation; inconsistent timing margins, no official NXP support, missing version 2.0 improvements (CRC correction, timer prescaler). | Not qualified for commercial deployment - fails reliability testing under EMI stress or extended temperature cycling. | Avoid RC522 clones in production systems; MFRC52201HN1,115 guarantees full NXP datasheet compliance, long-term supply, and automotive-grade qualification. |
Compared with PN5120A01HN/C1 and RC522 clones, MFRC52201HN1,115 delivers certified MIFARE DESFire EV1 support, robust 848 kBd timing, and NXP's full lifecycle commitment - making it the only choice for secure, standards-compliant, and field-deployable MIFARE/NTAG reader designs.

FAQ
What communication protocols does the MFRC52201HN1,115 support?
The MFRC52201HN1,115 supports ISO/IEC 14443 A/MIFARE (including Mini, 1K, 4K, Ultralight, DESFire EV1, and Plus) and NTAG protocols. It does not support ISO/IEC 14443 B, FeliCa, or NFC Forum Type 4 tag emulation. All protocol handling - including framing, parity, and CRC-16 - is performed internally by the MFRC52201HN1,115 digital baseband engine.
Does the MFRC52201HN1,115 require an external crystal oscillator?
Yes, the MFRC52201HN1,115 requires a 27.12 MHz quartz crystal connected between OSCIN and OSCOUT pins. The internal oscillator circuit is designed exclusively for this frequency and cannot operate with external clock sources or lower-frequency crystals. No additional load capacitors are specified in the datasheet, but board-level parasitics must be accounted for during layout.
How does the MFRC52201HN1,115 handle host interface selection?
The MFRC52201HN1,115 performs automatic host interface detection at power-on or hard reset by sampling logic levels on SDA/NSS/RX, EA, and D1–D7 pins. Configuration is determined by Table 5 in the datasheet - no firmware initialization or strap pins are needed. This allows one hardware design to support SPI, I²C, or UART without physical modification.
What is the maximum operating distance achievable with the MFRC52201HN1,115?
The MFRC52201HN1,115 achieves a typical operating distance of up to 50 mm in Read/Write mode, measured with a properly tuned 40 Ω antenna matching network between TX1 and TX2. Performance depends on antenna geometry, coil Q-factor, and environmental shielding - actual range in end equipment may vary between 30–50 mm under real-world conditions.
Is the MFRC52201HN1,115 pin-compatible with the MFRC52202HN1,115?
Yes, the MFRC52201HN1,115 and MFRC52202HN1,115 share identical HVQFN32 pinout, electrical characteristics, and register map. Version 2.0 adds enhanced CRC handling when RX Multiple = 1, improved stability in electrically noisy environments, and an additional timer prescaler - all implemented without altering pin function or timing requirements.
