Product details
Overview
NCF3340AHN/00310Y 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 supporting ISO/IEC 14443 A/B, FeliCa, MIFARE, NFC Forum Tags 1–5, and ISO/IEC 15693 at up to 848 kbit/s in Read/Write mode.
For engineers reviewing the NCF3340AHN/00310Y datasheet, NCF3340AHN/00310Y pinout, NCF3340AHN/00310Y application, or NCF3340AHN/00310Y equivalent, key selection considerations include its -40°C to +85°C operating range, HVQFN40 package, <1 mW polling power, embedded firmware enabling direct host connection, and support for card emulation (T4T), peer-to-peer, and reader/writer modes per NFCIP-1/NFCIP-2.
Technical Context
The NCF3340AHN/00310Y implements a dedicated NFC protocol stack in embedded firmware, exposing only the standardized NFC Controller Interface (NCI) to the host - eliminating need for host-side NFC stack development. Its ARM Cortex-M0 core executes polling loops with configurable low-power states and active load modulation.
RF operation is fully self-contained: integrated driver supports 2.7–5.5 V supply with ≤170 mA peak current, and on-chip self-test verifies antenna integrity during production. It supports all three NFC operating modes - Read/Write, Peer-to-Peer, and Card Emulation - with hardware-accelerated modulation/demodulation compliant to NFCIP-1 and NFCIP-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Carrier Frequency | 13.56 MHz - fixed RF carrier enabling interoperability with global NFC infrastructure and tags. |
| Max Data Rate (R/W) | 848 kbit/s - enables high-speed tag interrogation and data exchange with ISO/IEC 14443 A/B and FeliCa. |
| RF Supply Voltage | 2.7–5.5 V - supports direct connection to common automotive power rails without external LDO. |
| Peak RF Current | 170 mA max - defines minimum capability of external power stage; enables >100 mm read range with optimized antenna. |
| Low-Power Polling | <1 mW - reduces thermal load and extends battery life in always-on vehicle access systems. |
| Operating Temperature | -40°C to +85°C - meets AEC-Q100 Grade 3 requirements for cabin-mounted automotive electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST25DV04K-IER | EEPROM-based dynamic NFC tag (I²C + RF); no embedded MCU or NCI firmware; supports only Reader/Writer mode. | Limited to passive data storage and simple sensor readout; cannot perform card emulation or peer-to-peer. | Select when only tag-like functionality is needed and host MCU handles full NFC protocol stack. |
| PN7150B0HN/C1 | Automotive-qualified NFC controller with NCI interface; same HVQFN40 package; supports identical ISO/IEC 14443 A/B, FeliCa, and tag types but lacks integrated self-test and has higher polling power (~1.5 mW). | Valid drop-in replacement for most NCF3340AHN/00310Y designs requiring same footprint and interface; requires validation of self-test omission in production test flow. | Choose when leveraging existing PN7150 design assets or prioritizing vendor consolidation with STMicroelectronics. |
Compared with ST25DV04K-IER and PN7150B0HN/C1, the NCF3340AHN/00310Y uniquely combines embedded firmware, integrated self-test, and sub-1-mW polling - making it optimal for automotive systems requiring certified, low-power, production-ready NFC with minimal host software overhead.

FAQ
What host interfaces does the NCF3340AHN/00310Y support?
The NCF3340AHN/00310Y supports both I²C and SPI host interfaces compliant with the NFC Forum NCI specification. I²C operates up to 400 kHz and SPI up to 10 MHz in mode 0. Both interfaces provide identical NCI command/response messaging, allowing flexible host MCU selection - the NCF3340AHN/00310Y does not require custom driver development when used with standard NCI stacks for Linux®, Android™, or AUTOSAR.
Does the NCF3340AHN/00310Y support card emulation mode?
Yes, the NCF3340AHN/00310Y supports Card Emulation Mode (CEM) from host via NFC Forum Type 4 Tag (T4T) implementation compliant with ISO/IEC 14443 A/B at 106 kbit/s. It uses active load modulation and embedded firmware to emulate a contactless smartcard without external components - the NCF3340AHN/00310Y is validated for use in driver authorization and secure payment applications requiring T4T compliance.
What is the operating temperature range for the NCF3340AHN/00310Y?
The NCF3340AHN/00310Y is rated for -40°C to +85°C ambient operation, meeting AEC-Q100 Grade 3 requirements for automotive cabin applications. This rating applies to the NCF variant; the NCJ variant extends to +105°C for under-hood use. The NCF3340AHN/00310Y part number specifically corresponds to the NCF grade, and its thermal performance is validated across this full range with HVQFN40 package thermal characteristics.
How does the integrated self-test function in the NCF3340AHN/00310Y?
The NCF3340AHN/00310Y performs an on-chip RF self-test during power-up or on command, measuring antenna resonance frequency, impedance match, and RF path integrity without external equipment. It reports pass/fail status via NCI message - this feature eliminates need for external NFC field generators in production test, reducing test time and cost. The NCF3340AHN/00310Y self-test is factory-calibrated and documented in AUTONCF3340LF REV 0.
Is the NCF3340AHN/00310Y pin-compatible with other NXP NFC controllers?
The NCF3340AHN/00310Y uses the HVQFN40 package with wettable flanks and shares identical pinout with PN7150B0HN/C1 and PN7160B0HN/C1 - including VDD_RF, VDD_IO, ANT1/ANT2, IRQ, and I²C/SPI signals. However, firmware and register mapping differ; migration requires host software update. The NCF3340AHN/00310Y is not a drop-in replacement but offers mechanical compatibility for board reuse where firmware changes are acceptable.
