Product details
Overview
PN5331B3HN/C270:55 from NXP Semiconductors is a Near Field Communication (NFC) controller IC built on an 80C51 microcontroller core, supporting ISO/IEC 14443A/MIFARE, FeliCa, ISO/IEC 14443B, and NFCIP-1 (ECMA-340) protocols. It delivers bidirectional data rates up to 424 kbit/s, integrates RF demodulation/decoding, framing, and error detection (CRC/parity), and operates across 2.5–3.6 V non-USB or 4.02–5.25 V USB supply. It enables secure contactless reader/writer and card emulation in consumer computing and access control systems.
For engineers reviewing the PN5331B3HN/C270:55 datasheet, PN5331B3HN/C270:55 pinout, PN5331B3HN/C270:55 application, or PN5331B3HN/C270:55 equivalent, key selection considerations include its 40-pin HVQFN package, integrated 27.12 MHz oscillator with internal PLL, USB 2.0 full-speed and high-speed UART host interfaces, MIFARE/FeliCa emulation capability, and support for external secure IC via NFC-WI/S2C interface.
Technical Context
The PN5331B3HN/C270:55 implements a complete NFC transceiver stack including analog front-end (TX1/TX2, RX, LOADMOD), digital baseband processing (framing, CRC, anticollision handling for A/B/FeliCa/NFCIP-1), and embedded 80C51 MCU with 45056-byte ROM and 1224-byte RAM. Its RF interface supports passive and active communication modes per ISO/IEC 18092 and ECMA-340, with automatic wake-up from soft/hard power-down via HSU.
It features dedicated hardware blocks for MIFARE Classic encryption, FeliCa signal processing, and CIU (Contactless Interface Unit) interrupt management (CIU_IRQ_0/1), alongside configurable GPIOs (P30–P35, P70_IRQ), I²C master interface for EEPROM, and SVDD power switch for secure companion ICs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN7150B01HN/C1E | Lower power consumption (3 µA deep sleep); integrated NFC antenna driver; no 80C51 core - uses host-driven firmware | Targeted for ultra-low-power IoT sensors and wearables; lacks on-chip MIFARE crypto acceleration | Select PN7150B01HN/C1E when minimizing system power dominates over firmware autonomy and legacy MIFARE support |
| ST25DV04K-IER | Dynamic NFC tag IC (not controller); I²C interface only; no RF transmitter - requires external reader IC | Used in passive tag applications (e.g., smart posters, product authentication), not reader/emulation systems | Select ST25DV04K-IER only for NFC Forum Type 5 tag deployment - not a functional replacement for PN5331B3HN/C270:55 |
Compared with PN7150B01HN/C1E and ST25DV04K-IER, the PN5331B3HN/C270:55 uniquely combines embedded 80C51 processing, full MIFARE/FeliCa/NFCIP-1 protocol offload, and dual-mode RF transceiver in one HVQFN40 package - making it suitable for standalone, firmware-resident NFC reader designs where host processing resources are constrained.

FAQ
What host interfaces does the PN5331B3HN/C270:55 support?
The PN5331B3HN/C270:55 supports USB 2.0 full-speed (DP/DM), high-speed UART (HSU), and a restricted I²C master interface (SDA/SCL). USB and HSU are mutually exclusive via configuration pins I0/I1; I²C is used exclusively for external EEPROM control and cannot serve as primary host interface. All interfaces are managed by the embedded 80C51 core within PN5331B3HN/C270:55.
Does the PN5331B3HN/C270:55 include on-chip memory for firmware execution?
Yes, the PN5331B3HN/C270:55 contains 45056 bytes of on-chip ROM for firmware storage and 1224 bytes of RAM (IDATA + XRAM) for runtime execution. This allows autonomous operation without external code storage, and the memory map is partitioned into dedicated SFR, IDATA, and XRAM regions accessible via MOVX and standard 80C51 instructions - all integral to PN5331B3HN/C270:55 functionality.
Can the PN5331B3HN/C270:55 emulate MIFARE Classic cards?
Yes, the PN5331B3HN/C270:55 supports MIFARE Classic 1 KB and 4 KB emulation in card mode, including cryptographic operations for authentication and data exchange. It handles MIFARE-specific framing, anti-collision, and Crypto1 cipher acceleration in hardware - enabling secure emulation without host CPU involvement. This capability is explicitly defined in the PN5331B3HN/C270:55 datasheet Rev. 3.4.
What is the role of the SVDD pin on the PN5331B3HN/C270:55?
The SVDD pin on PN5331B3HN/C270:55 is a programmable power switch output delivering regulated 3.3 V to external secure ICs (e.g., smart card controllers), with built-in overload detection and firmware-controlled enable/disable. It is part of the ECMA-373 NFC-WI interface and ensures safe, sequenced power delivery during secure transaction handshakes - a defined function of PN5331B3HN/C270:55 per its pin description table.
How does the PN5331B3HN/C270:55 handle power management in battery-operated devices?
The PN5331B3HN/C270:55 offers Hard-Power-Down (10 µA) and Soft-Power-Down (30 µA) modes, both retaining register state and supporting automatic wake-up via HSU activity. In USB mode, it draws ≤250 µA in suspend state. These low-power states are controlled via PCON and firmware registers - enabling multi-week operation on coin-cell batteries in NFC tag readers, a key design feature of PN5331B3HN/C270:55.
