Product details
Overview
MFRC52302HN1,151 from NXP Semiconductors is a highly integrated 13.56 MHz contactless reader/writer IC supporting ISO/IEC 14443 A and B protocols, MIFARE Classic encryption (Mini/1K/4K), and up to 848 kBd bidirectional data transfer. It integrates analog front-end, digital protocol engine, 64-byte FIFO, CRC coprocessor, and internal oscillator - enabling standalone RFID read/write functionality in access control, transit ticketing, and secure identification systems.
For engineers reviewing the MFRC52302HN1,151 datasheet, MFRC52302HN1,151 pinout, MFRC52302HN1,151 application, or MFRC52302HN1,151 equivalent, this page delivers verified technical context, HVQFN32 package mapping, SPI/I²C/UART interface specifications, real-world operating distance (up to 50 mm), and validated alternative parts for NFC reader design and migration.
Technical Context
The MFRC52302HN1,151 implements a full ISO/IEC 14443 A/B physical and data-link layer stack - including ASK modulation (100%), modified Miller and Manchester encoding, subcarrier demodulation, parity generation/check, and CRC-16 per ISO/IEC 14443-3. Its analog interface drives antenna circuits directly via TX1/TX2 with no external active components required.
Digital subsystems include a programmable timer, flexible interrupt controller (IRQ output), hard/soft power-down modes (≤5 µA hard reset current), and host interface auto-detection logic that identifies SPI, I²C, or UART based on fixed pin states (I2C, EA, D1–D7) at power-on. The 64-byte FIFO buffers both transmit and receive data independently.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 13.56 MHz carrier - enables interoperability with ISO/IEC 14443 A/B cards and MIFARE transponders. |
| Data Rates | Up to 848 kBd (ISO/IEC 14443 A); supports 106/212/424/848 kBd modes - allows high-speed transaction handling in transit and payment terminals. |
| Supply Voltage | 2.5 V to 3.3 V (VDDA/VDDD/VDD(TVDD)); PVDD: 1.6–3.6 V - permits single-supply operation with LDO regulation and low-voltage system integration. |
| Power Consumption | Typical 7 mA analog current (AVDD), 6.5 mA digital current (DVDD); ≤5 µA hard power-down - enables battery-powered handheld readers with extended runtime. |
| Host Interfaces | SPI (10 Mbit/s), I²C (up to 3.4 Mbit/s High-speed mode), UART (up to 1228.8 kBd) - provides flexibility for microcontroller selection across cost, speed, and pin-count constraints. |
| Operating Distance | Up to 50 mm (typical, dependent on antenna size/tuning) - meets EN 14971 proximity requirements for access control and smart card readers. |
| FIFO Depth | 64-byte bidirectional buffer - eliminates host polling overhead and supports burst-mode communication for efficient command-response cycles. |
Pinout & Package
HVQFN32 (SOT617-1) package: 5 mm × 5 mm × 0.85 mm body, 32-terminal thermal-enhanced quad flat no-lead construction with exposed thermal pad (optional DVSS connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TX1 / TX2 | RF transmitter outputs | Drive 13.56 MHz modulated carrier to antenna; require external matching network (typically 40 Ω differential load). |
| RX | RF signal input | Receives demodulated response from ISO/IEC 14443 cards; connects to antenna via capacitive divider or balun. |
| IRQ | Interrupt request output | Active-low open-drain signal indicating completion of command, FIFO status, or error condition - enables event-driven host firmware. |
| NRSTPD | Reset & power-down input | Positive-edge reset; LOW enables hardware power-down (oscillator off, I/Os disconnected, current ≤5 µA). |
| SDA/NSS/RX | Multiplexed interface pin | Configures as I²C data (SDA), SPI chip select (NSS), or UART address (RX) - determined by EA/D1–D7 pin states at boot. |
| MFIN / MFOUT | MIFARE auxiliary interface | Supports direct connection to MIFARE ICs for power delivery (SVDD) and secure channel extension beyond standard RF link. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless reader applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN5180AUHN/C1 | Higher RF output (±1 dBm), integrated DC-DC converter, supports ISO/IEC 14443 A/B and FeliCa - but requires external crystal and lacks MIFARE Classic crypto acceleration. | Better suited for multi-standard (FeliCa + ISO) readers; not drop-in for MIFARE-only legacy systems requiring hardware AES/MIFARE key handling. | Select PN5180AUHN/C1 when upgrading to dual-standard support and higher RF performance; retain MFRC52302HN1,151 for cost-sensitive MIFARE 1K/4K deployments. |
| SLI13B02001 | Standalone 13.56 MHz reader IC with identical HVQFN32 footprint and pin-compatible SPI/I²C interfaces - but limited to ISO/IEC 14443 A only and no MIFARE encryption engine. | Applicable for basic MIFARE read/write where cryptographic operations are handled externally by host MCU - lacks on-chip MIFARE key storage and authentication logic. | Choose SLI13B02001 for simplified, lower-cost reader designs without embedded MIFARE crypto needs; use MFRC52302HN1,151 when hardware-accelerated MIFARE authentication is mandatory. |
Compared with PN5180AUHN/C1 and SLI13B02001, the MFRC52302HN1,151 uniquely combines MIFARE Classic hardware crypto acceleration, full ISO/IEC 14443 A/B protocol stack, and ultra-low power-down current - making it optimal for legacy-compliant, security-critical, and battery-operated MIFARE reader applications.

FAQ
What is the maximum operating distance supported by the MFRC52302HN1,151?
The MFRC52302HN1,151 achieves a typical operating distance of up to 50 mm in Read/Write mode, contingent on antenna size, geometry, and tuning. This performance assumes a well-matched 40 Ω differential antenna load between TX1 and TX2 pins and nominal 3.3 V supply. Real-world range may vary with environmental factors such as nearby metal or shielding.
Does the MFRC52302HN1,151 support MIFARE Classic encryption natively?
Yes, the MFRC52302HN1,151 includes dedicated hardware for MIFARE Classic encryption - supporting MIFARE Mini, MIFARE 1K, and MIFARE 4K authentication and sector read/write operations without host MCU intervention. Its internal crypto unit handles key storage, challenge-response, and encrypted data transfer per MIFARE Classic protocol.
Which host interfaces does the MFRC52302HN1,151 support, and what are their maximum speeds?
The MFRC52302HN1,151 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 based on pin strapping (I2C, EA, D1–D7), and all three are fully functional without firmware reconfiguration or external level-shifting circuitry.
Is an external crystal required for the MFRC52302HN1,151 to operate?
Yes, the MFRC52302HN1,151 requires a 27.12 MHz quartz crystal connected between OSCIN and OSCOUT pins for precise 13.56 MHz carrier generation. Alternatively, an external 27.12 MHz clock source may be applied to OSCIN with OSCOUT left unconnected - but crystal configuration is recommended for stability and EMI performance.
What power supply configurations does the MFRC52302HN1,151 require?
The MFRC52302HN1,151 uses five independent supply domains: VDDA/VDDD/VDD(TVDD) at 2.5–3.3 V (must be equal), PVDD at 1.6–3.6 V (≤VDDD), and SVDD at 1.6–3.6 V. AVDD and DVDD must be decoupled with 100 nF ceramic capacitors close to pins 15 and 3 respectively; TVDD requires ≥10 µF bulk capacitance due to high RF current demand.
