Product details
Overview
NCF3340EHN/00350Y from NXP is an automotive-qualified NFC controller IC with integrated ARM® Cortex®-M0 core, NCI-compliant I²C/SPI host interface, and full NFC Forum compliance for read/write, peer-to-peer, and host-card emulation modes. It operates at 13.56 MHz, supports ISO/IEC 14443 A/B, FeliCa, MIFARE, and NFC Forum tag types, and delivers <1 mW polling power in HVQFN40 package for driver authorization and vehicle diagnostics applications.
For engineers reviewing the NCF3340EHN/00350Y datasheet, NCF3340EHN/00350Y pinout, NCF3340EHN/00350Y application, or NCF3340EHN/00350Y equivalent, key selection considerations include automotive temperature range (-40°C to +85°C), embedded NCI firmware, RF supply voltage (2.7–5.5 V), max transmitter current (170 mA), and low-power card detection mode (200 µA).
Technical Context
The NCF3340EHN/00350Y implements NFCIP-1 and NFCIP-2 protocols for peer-to-peer communication and supports all three NFC operating modes-read/write, peer-to-peer, and card emulation-with ISO/IEC 14443 A/B, FeliCa (212/424 kbit/s), and NFC Forum Type 1–5 tag handling. Its integrated Cortex-M0 enables configurable polling loops and active load modulation.
RF operation uses a dedicated 2.7–5.5 V supply with ≤170 mA peak current; power management includes hard power-down (<10 µA), RF-level-detection wake-up (20 µA), and low-power card detection (200 µA). The device is qualified per AEC-Q100 Grade 2 and operates across -40°C to +85°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST25DV04K | EEPROM-based dynamic NFC tag IC; no embedded MCU or NCI firmware; I²C-only interface; no peer-to-peer or card emulation support. | Limited to passive data storage and simple sensor readout; unsuitable for host-controlled NFC transactions. | Select only when NFC functionality is strictly one-way read/write of static configuration data. |
| PN7150B0HN/C1 | Also NXP automotive NFC controller; supports same NCI interface and ISO/IEC 14443/FeliCa protocols but lacks integrated Cortex-M0 and requires external firmware loading. | Higher host CPU load and longer boot time; less suitable for real-time RTOS environments requiring deterministic polling. | Prefer NCF3340EHN/00350Y where embedded firmware, low-latency polling, and reduced host dependency are critical. |
Compared with ST25DV04K and PN7150B0HN/C1, the NCF3340EHN/00350Y uniquely combines AEC-Q100 qualification, embedded Cortex-M0, and production-ready NCI firmware-enabling faster integration into automotive RTOS platforms while maintaining full NFC Forum interoperability and <1 mW polling efficiency.

FAQ
What automotive qualification does the NCF3340EHN/00350Y meet?
The NCF3340EHN/00350Y is qualified per AEC-Q100 Grade 2, covering operating temperature from -40°C to +85°C, thermal cycling, mechanical shock, and ESD robustness to ISO 10605. This certification validates its suitability for non-engine-compartment automotive applications including door modules, infotainment, and seat control units where the NCF3340EHN/00350Y serves as the primary NFC interface.
Does the NCF3340EHN/00350Y require external firmware loading?
No-the NCF3340EHN/00350Y includes fully embedded NFC firmware compliant with the NFC Forum NCI specification. It boots autonomously and supports I²C/SPI host communication out-of-box, eliminating external flash memory and firmware update infrastructure. This design reduces BOM cost and accelerates time-to-market for systems integrating the NCF3340EHN/00350Y.
What is the maximum operating distance supported by the NCF3340EHN/00350Y?
The NCF3340EHN/00350Y supports up to 100 mm operating distance under optimal conditions-including properly tuned 60 mm × 60 mm antenna, ideal coil geometry, and low-noise environment. Distance varies with antenna size, matching components, and electromagnetic interference; the NCF3340EHN/00350Y's 170 mA max RF current and active load modulation enable consistent performance across this range.
Which host operating systems have validated drivers for the NCF3340EHN/00350Y?
Production-ready drivers for the NCF3340EHN/00350Y are provided by NXP for Linux®, Android™, and AUTOSAR-compliant NCI stacks. These drivers abstract low-level register access and handle NCI message framing, enabling rapid integration into automotive RTOS environments where the NCF3340EHN/00350Y operates as a plug-and-play NFC peripheral.
Can the NCF3340EHN/00350Y perform card emulation without host processor involvement?
Yes-the NCF3340EHN/00350Y supports host-card emulation (HCE) mode via ISO/IEC 14443 A/B at 106 kbit/s using its integrated Cortex-M0 core and embedded firmware. While the host initiates the mode, the NCF3340EHN/00350Y handles modulation, timing, and protocol state transitions autonomously, reducing latency and CPU load during secure transaction sequences.
