Product details
Overview
OM26630FDKM from NXP Semiconductors is a high-performance multi-protocol NFC frontend IC supporting ISO/IEC 14443A/B, FeliCa (JIS X 6319-4), ISO/IEC 15693, ISO/IEC 18000-3 Mode 3/EPC Class-1 HF, and P2P passive initiator mode per ISO/IEC 18092. It delivers up to 848 kbit/s transfer speed for MIFARE Classic and 424 kbit/s for FeliCa, with integrated transmitter capable of driving reader antennas without external active circuitry, and built-in 512-byte FIFO for high-throughput transaction handling in access control terminals.
For engineers reviewing the OM26630FDKM datasheet, OM26630FDKM pinout, OM26630FDKM application, or OM26630FDKM equivalent, key selection considerations include its HVQFN32 wettable flanks package, dual I²C interfaces (host + SAM), low-power card detection (LPCD) support, 3.0–5.5 V supply range, and hardware-accelerated MIFARE Classic encryption - all critical for secure, compact, battery-aware NFC reader designs.
Technical Context
The OM26630FDKM implements a fully integrated analog front-end with two independent 13.56 MHz transmitters (TX1/TX2), differential RF receiver (RXP/RXN), and internal VMID reference generation. Its digital baseband handles ISO/IEC 14443-A framing, CRC/parity error detection, and FeliCa demodulation/decoding - offloading layer-2 protocol processing from the host MCU.
It features five programmable timers (four 16-bit + one LFO-based wake-up timer), dedicated SAM interface with separate I²C bus, and flexible host connectivity via SPI (up to 10 Mbit/s), UART (RS-232 level, up to 1228.8 kBd), or I²C (Fast-mode Plus, up to 1000 kBd), enabling deterministic real-time response in industrial and payment-grade readers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 3.0 V to 5.5 V - supports direct integration with 3.3 V or 5 V system rails without level-shifting. |
| RF Frequency | 13.56 MHz - compliant with global HF RFID/NFC standards; crystal oscillator input at 27.12 MHz enables precise PLL-derived clocking. |
| Max Data Rate | 848 kbit/s (ISO/IEC 14443-A/MIFARE) - enables fast credential reads in high-throughput access systems. |
| FIFO Size | 512 bytes - buffers full command/response frames, reducing host interrupt frequency and improving transaction latency. |
| Power-Down Current | 8 nA typical - enables ultra-low-power card presence detection in battery-powered kiosks and portable readers. |
| Operating Temp | −25 °C to +85 °C - qualified for industrial indoor/outdoor deployment including building automation and ticketing terminals. |
| Host Interfaces | SPI, UART, I²C (two instances) - allows simultaneous connection to main host MCU and secure access module (SAM) without multiplexing. |
Pinout & Package
OM26630FDKM is packaged in HVQFN32 (SOT617-1), 5 × 5 × 0.85 mm, with wettable flanks for automated optical inspection (AOI) and reliable solder joint validation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TX1 / TX2 | RF Transmitter Outputs | Drive antenna matching network; dual outputs support differential or single-ended antenna configurations with optimized EMI performance. |
| RXP / RXN | Differential RF Receiver Inputs | Enable high-SNR signal acquisition in noisy environments; reject common-mode interference from adjacent electronics. |
| VMID | Internal Receiver Reference | Provides stable mid-rail bias for analog receiver chain; requires no external component, simplifying BOM. |
| IRQ | Interrupt Request Output | Asserts asynchronous event notification (e.g., card detected, Rx complete, Tx finished) to host MCU - eliminates polling overhead. |
| SCL / SDA (I²C) | Host Interface Bus | Primary I²C interface for register configuration and data exchange; supports Fast-mode Plus (1000 kBd) for rapid firmware updates. |
| SCL_SAM / SDA_SAM | Secure Access Module Interface | Dedicated I²C bus for SAM communication - isolates cryptographic key handling from main host path, meeting EMVCo and Common Criteria requirements. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware MIFARE Classic Encryption | Accelerates authentication and sector read/write operations in <10 ms - eliminates software crypto bottlenecks in high-speed credential verification. |
| Low-Power Card Detection (LPCD) | Configurable sensitivity thresholds and timing windows enable sub-10 µA average current during standby - extends battery life in portable NFC readers. |
| Integrated PLL | Derives precise 13.56 MHz carrier from 27.12 MHz crystal - removes need for external RF synthesizer, reducing PCB area and BOM cost. |
| Multi-Protocol Framing Engine | Handles ISO/IEC 14443-A/B, FeliCa, and ISO/IEC 15693 framing/CRC autonomously - relieves host MCU of time-critical bit-level protocol management. |
| Wettable Flank HVQFN32 | Enables AOI-compatible reflow soldering and IPC-A-610-compliant visual inspection - improves manufacturing yield in high-volume consumer and industrial production. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC frontend applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PN5180A0HN/C1 | Single 13.56 MHz transmitter; no dedicated SAM I²C; supports NFC Forum LLCP but lacks FeliCa decoding. | Better suited for Android-compliant peer-to-peer or card emulation; not certified for FeliCa or EMV contactless. | Select PN5180A0HN/C1 only when FeliCa and hardware MIFARE crypto are unnecessary and LLCP stack integration is prioritized. |
| CLRC66403HNE | Successor with enhanced EMI immunity, extended LPCD range, and updated EMVCo certification (v4.0); same HVQFN32 footprint. | Required for new EMVCo Level 1 certification submissions after Q3 2025; backward-compatible register map. | Choose CLRC66403HNE for greenfield designs targeting long-term certification compliance and improved noise resilience in dense RF environments. |
Compared with PN5180A0HN/C1, OM26630FDKM provides full FeliCa decode and hardware MIFARE encryption essential for Japan and EU transit systems; versus CLRC66403HNE, it offers proven qualification for legacy EMVCo v3.2 deployments and lower unit cost where latest certification isn't mandated.

FAQ
What protocols does OM26630FDKM support natively without host firmware intervention?
OM26630FDKM natively handles ISO/IEC 14443-A framing, CRC/parity, FeliCa demodulation/decoding, and ISO/IEC 15693 framing - all within its hardware baseband. It also performs hardware-accelerated MIFARE Classic authentication and encryption. Host firmware manages higher-layer protocols (e.g., APDU exchange, SAM session keys), but bit-level RF timing, modulation, and error detection are fully autonomous in OM26630FDKM.
Does OM26630FDKM require external RF matching components?
Yes - OM26630FDKM requires an external antenna matching network (typically L-C tank with series/parallel capacitors and resistors) between TX1/TX2 outputs and the antenna coil. The IC integrates the 13.56 MHz transmitter power amplifier but does not include antenna tuning components; design guidelines for 50 Ω or 100 Ω differential matching are provided in NXP AN11759.
Can OM26630FDKM operate with a 2.5 V supply?
No - OM26630FDKM corresponds to the CLRC66301/02 variant family, which specifies a minimum supply voltage of 3.0 V (see Table 1, Quick Reference Data). The 2.5 V minimum applies only to CLRC66303 variants (e.g., CLRC66303HNE), not OM26630FDKM. Operating below 3.0 V risks functional failure or undefined behavior.
How is the Secure Access Module (SAM) interfaced to OM26630FDKM?
OM26630FDKM provides a dedicated I²C interface (pins SCL_SAM and SDA_SAM) physically and electrically isolated from the main host I²C bus. This dual-I²C architecture prevents side-channel leakage between SAM cryptographic operations and host data traffic, satisfying EMVCo and Common Criteria requirements for secure key storage and transaction signing in OM26630FDKM-based payment terminals.
What is the maximum practical read distance achievable with OM26630FDKM?
With a well-tuned 50 mm × 50 mm PCB antenna and optimal matching, OM26630FDKM achieves up to 12 cm read distance for ISO/IEC 14443-A cards (e.g., MIFARE Classic 1K) under ideal lab conditions. Real-world distance depends on card type, antenna geometry, enclosure materials, and regulatory field strength limits - typical deployed systems achieve 5–8 cm in metal-enclosed access panels.
