Product details
Overview
MFRC52201HN1,118 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), Ultralight, DESFire EV1, Plus, and NTAG tags in access control, transit ticketing, and smart card authentication.
For engineers reviewing the MFRC52201HN1,118 datasheet, MFRC52201HN1,118 pinout, MFRC52201HN1,118 application, or MFRC52201HN1,118 equivalent, this page delivers verified electrical specs, host interface timing (SPI up to 10 Mbit/s, I²C up to 3.4 Mbit/s, UART up to 1228.8 kBd), RF performance (typ. 50 mm read range), power supply requirements (2.5–3.3 V), and validated alternative parts for migration or sourcing flexibility.
Technical Context
The MFRC52201HN1,118 implements a complete ISO/IEC 14443 A physical layer with integrated transmitter (TX1/TX2) driving antenna loads up to 40 Ω, receiver (RX input) with I/Q demodulation, and digital baseband handling framing, parity, and CRC-16 per ISO/IEC 14443-3. Its internal oscillator supports 27.12 MHz crystal or external clock input via OSCIN/OSCOUT.
It supports three host interfaces-SPI (slave mode, MSB-first, NSS-controlled), I²C-bus (slave-only, 7-bit address configurable via EA/ADR pins), and UART (RS232-compatible, voltage-level dependent on pin supply)-with automatic interface detection at reset. The device includes programmable timers, interrupt control (IRQ output), and MFIN/MFOUT for powering external smart cards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless reader IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN5120A0HN/C1 | Successor IC with NFC Forum certification, integrated NFC controller, and extended ISO/IEC 18092 support; requires updated firmware stack. | Required for new designs targeting NFC peer-to-peer or card emulation; not drop-in compatible due to register map changes. | Choose PN5120A0HN/C1 for NFC-enabled products needing ISO/IEC 18092 or LLCP compliance. |
| RC522 (clone variant) | Unlicensed third-party implementation lacking NXP's MIFARE DESFire EV1/Plus certification, inconsistent CRC behavior, and no official support. | Suitable only for non-security prototyping; fails in production environments requiring MIFARE ecosystem compatibility. | Select MFRC52201HN1,118 for certified interoperability with MIFARE infrastructure and long-term supply assurance. |
Compared with PN5120A0HN/C1, MFRC52201HN1,118 offers lower BOM cost and proven MIFARE 1K/4K/DESFire EV1 interoperability but lacks native NFC Forum certification; versus RC522 clones, it guarantees full ISO/IEC 14443 A compliance and NXP's security-hardened firmware stack.

FAQ
What host interfaces does the MFRC52201HN1,118 support?
The MFRC52201HN1,118 supports SPI (up to 10 Mbit/s), I²C-bus (up to 3.4 Mbit/s in High-speed mode), and UART (up to 1228.8 kBd). Interface selection is automatic at power-on reset based on pin strapping (I2C, EA, D1–D7). All interfaces operate in slave mode, with dedicated register maps and timing requirements defined in Sections 8.1.2–8.1.4 of the datasheet. MFRC52201HN1,118 requires no external level shifters for 3.3 V logic systems.
Does the MFRC52201HN1,118 support MIFARE DESFire EV1 and NTAG?
Yes, the MFRC52201HN1,118 natively supports MIFARE DESFire EV1, NTAG213/215/216, MIFARE Classic 1K/4K, MIFARE Ultralight, and MIFARE Plus protocols per ISO/IEC 14443 A. It handles all required framing, CRC-16, parity, and anti-collision sequences in hardware. MFRC52201HN1,118 achieves full interoperability with these tags when configured per NXP Application Note AN11273 and uses the same command set as the MFRC523 for backward compatibility.
What is the maximum operating distance of the MFRC52201HN1,118?
The MFRC52201HN1,118 achieves a typical operating distance of up to 50 mm in read/write mode, measured with a well-tuned 40 Ω antenna matching network at 13.56 MHz. Actual range depends on antenna geometry, PCB layout, tag type (e.g., NTAG213 vs. MIFARE 4K), and environmental factors like metal proximity. Performance degrades below 3 V supply; optimal range occurs at 3.3 V with TX1/TX2 outputs configured per Section 8.2.1.
How does the MFRC52201HN1,118 handle power management?
The MFRC52201HN1,118 provides two low-power states: hard power-down (≤5 µA, activated by pulling NRSTPD LOW) disables oscillator and disconnects I/O pins; soft power-down (≤10 µA) retains register state and enables RF level detection. Both modes support wake-up via IRQ or external reset. Supply rails include separate AVDD (analog), DVDD (digital), TVDD (transmitter), and PVDD (pin drivers), allowing selective shutdown of RF sections while preserving host communication.
Is the MFRC52201HN1,118 pin-compatible with the MFRC52202HN1?
Yes, the MFRC52201HN1,118 and MFRC52202HN1 share identical HVQFN32 (SOT617-1) packaging, pinout, and electrical characteristics. MFRC52202HN1 adds improved stability in harsh conditions, an extra timer prescaler, and corrected CRC handling when RX Multiple = 1-but maintains full functional and pin-to-pin compatibility. MFRC52201HN1,118 firmware runs unchanged on MFRC52202HN1, though new features require updated register access.
