FAQ

What distinguishes MFRC52202HN1,115 from MFRC52201HN1?

The MFRC52202HN1,115 is the version-2.0 revision of the MFRC522 series, adding increased stability in electrically noisy environments, an additional timer prescaler register, and corrected CRC handling when RX Multiple = 1. These enhancements improve interoperability with certain MIFARE DESFire EV1 and Ultralight variants under marginal RF conditions - while maintaining full pin and software compatibility with MFRC52201HN1.

Does MFRC52202HN1,115 support MIFARE DESFire EV1 and NTAG213/215/216?

Yes, MFRC52202HN1,115 explicitly supports ISO/IEC 14443 A/MIFARE and NTAG protocols, including MIFARE DESFire EV1 and NTAG213/215/216. Its analog front-end and digital baseband comply with the modulation, framing, and timing requirements defined in ISO/IEC 14443-2 and -3, enabling full read/write and authentication operations with these tag families when used with appropriate host firmware.

What antenna design considerations apply to MFRC52202HN1,115?

MFRC52202HN1,115 drives antennas via differential TX1/TX2 outputs optimized for a 40 Ω matched impedance at 13.56 MHz. Recommended antenna layouts use a 5–7 cm² planar coil with series capacitor tuning; PCB trace antennas require careful impedance matching and shielding from nearby digital traces. The datasheet specifies typical operating distance up to 50 mm with a properly tuned antenna - actual range depends on coil Q-factor, enclosure materials, and EMI environment.

Can MFRC52202HN1,115 operate from a single 3.3 V supply?

Yes, MFRC52202HN1,115 can operate from a single 3.3 V supply applied to VDDA, VDDD, and VDD(TVDD) simultaneously, provided PVDD and SVDD are also supplied at ≤3.3 V. However, optimal RF performance (especially read range) is achieved when analog (AVDD), digital (DVDD), and transmitter (TVDD) supplies are independently decoupled - as specified in Section 12.2 of the datasheet - to minimize noise coupling into sensitive RF paths.

Is MFRC52202HN1,115 RoHS compliant and qualified for industrial temperature range?

Yes, MFRC52202HN1,115 is RoHS compliant and rated for industrial ambient temperature operation from −25 °C to +85 °C in the HVQFN32 (SOT617-1) package. This qualification is confirmed in Table 1 (Quick reference data) and Table 2 (Ordering information) of the official NXP datasheet Rev. 3.9, ensuring suitability for deployment in uncontrolled environments such as outdoor kiosks, transit gateways, and factory-floor access panels.
