It delivers up to 848 kBd bidirectional transfer speed, operates from 2.5 V to 3.3 V, integrates a 27.12 MHz crystal oscillator, and achieves typical read/write distances up to 50 mm with matched antenna design. It serves as the RF frontend in access control, ticketing, and NFC-enabled payment terminals.

For engineers reviewing the MFRC52202HN1,118 datasheet, MFRC52202HN1,118 pinout, MFRC52202HN1,118 application, or MFRC52202HN1,118 equivalent, key selection considerations include its triple-host interface support (SPI up to 10 Mbit/s, I²C up to 3.4 Mbit/s, UART up to 1228.8 kBd), integrated CRC coprocessor, 64-byte FIFO buffer, and version-2.0-specific enhancements including improved stability under EMI stress and corrected RX Multiple CRC handling.

Technical Context

The MFRC52202HN1,118 implements a complete analog front-end for 13.56 MHz contactless communication, featuring dual transmitter outputs (TX1/TX2) with independent TVDD supply and internal amplitude regulation. Its digital baseband handles full ISO/IEC 14443 A framing, parity, and CRC-16 generation/check per Part 3, with automatic protocol detection across SPI, I²C, and UART interfaces at power-on reset.

It supports MIFARE Classic encryption (MF1xxS20/S50/S70), NTAG compatibility, and MFIN/MFOUT auxiliary power delivery to passive smart cards. The device includes a programmable timer, hard/soft power-down modes (≤10 µA soft PD current), and on-chip self-test capability - all within a single HVQFN32 package with thermal enhancement.

FAQ

What distinguishes MFRC52202HN1,118 from MFRC52201HN1?

The MFRC52202HN1,118 is version 2.0 of the MFRC522 series and maintains full pin and register compatibility with MFRC52201HN1. Key improvements include increased stability under electromagnetic interference, an additional timer prescaler for finer timing resolution, and corrected CRC handling when RX Multiple is enabled - all verified in NXP's Rev. 3.9 datasheet. These enhancements make MFRC52202HN1,118 preferable for harsh industrial environments where robustness is critical.

Does MFRC52202HN1,118 support MIFARE DESFire EV1 cards?

Yes, MFRC52202HN1,118 explicitly supports MIFARE DESFire EV1 and MIFARE Plus protocols as stated in Section 1 of the official datasheet. It handles the ISO/IEC 14443 A physical layer and framing required for DESFire EV1 authentication and data exchange, though higher-layer cryptographic operations must be executed by the host microcontroller. MFRC52202HN1,118 provides the necessary RF interface, CRC, and timing control to enable full DESFire EV1 interoperability.

What host interfaces does MFRC52202HN1,118 support and at what speeds?

MFRC52202HN1,118 supports SPI (up to 10 Mbit/s), I²C-bus (up to 400 kBd in Fast mode, 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 static pin voltages - no firmware configuration is needed to enable a specific interface. All three interfaces share the same register map and command set, simplifying host driver development across platforms.

Can MFRC52202HN1,118 operate from a single 3.3 V supply?

Yes, MFRC52202HN1,118 can operate from a single 3.3 V supply applied to VDDA, VDDD, and VDD(TVDD) simultaneously, as confirmed in Table 1 (Quick Reference Data). PVDD may be supplied at the same 3.3 V or reduced to 1.8 V for MFIN/MFOUT circuitry. This simplifies power design in 3.3 V systems, eliminating need for multiple regulators - though separate analog/digital ground routing remains recommended for optimal RF performance.

What is the maximum practical read/write distance achievable with MFRC52202HN1,118?

The datasheet specifies a typical operating distance of up to 50 mm in Read/Write mode, contingent on antenna size, geometry, and impedance matching to the 40 Ω differential TX1–TX2 output. Real-world performance depends on PCB layout, enclosure materials, and card type - MIFARE Ultralight typically achieves ~45 mm, while MIFARE 1K reaches ~50 mm with a well-tuned 50 mm × 50 mm loop antenna. Performance drops significantly below 3 V supply or with suboptimal matching networks.
