Product details
Overview
NCF3340AHN/00301Y from NXP is an automotive-qualified NFC controller with integrated ARM® Cortex®-M0 core, NCI-compliant I²C/SPI interface, and full NFC Forum compliance (NFCIP-1/NFCIP-2). It supports all NFC operating modes - Read/Write (ISO/IEC 14443 A/B, FeliCa, MIFARE, NFC Forum Types 1–5, ISO/IEC 15693), Peer-to-Peer, and Host Card Emulation (T4T at 106 kbit/s) - for secure driver authorization and vehicle diagnostics transmission.
For engineers reviewing the NCF3340AHN/00301Y datasheet, NCF3340AHN/00301Y pinout, NCF3340AHN/00301Y application, or NCF3340AHN/00301Y equivalent, key selection considerations include its -40°C to +85°C automotive temperature range, HVQFN40 package with wettable flanks, <1 mW polling power, embedded firmware enabling direct host integration, and support for AUTOSAR NCI stack and Linux/Android drivers.
Technical Context
The NCF3340AHN/00301Y implements a dedicated NFC protocol stack in on-chip firmware, offloading host processor tasks via standardized NCI v2.0 over I²C or SPI. Its integrated RF driver operates from 2.7–5.5 V with ≤170 mA peak current and supports active load modulation for robust tag communication.
It executes full NFCIP-1 and NFCIP-2 peer-to-peer protocols, ISO/IEC 14443 A/B card emulation at 106 kbit/s, and read/write up to 848 kbit/s across multiple standards including FeliCa (212/424 kbit/s), MIFARE 1K/4K, and NFC Forum Type 1–5 tags - all validated for interoperability in automotive environments.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST21NFCD | ARM Cortex-M0+ core; supports ISO/IEC 14443 A/B only (no FeliCa or ISO/IEC 15693); max RF current 130 mA. | Limited to basic access control and payment; not validated for automotive diagnostics or multi-standard tag reading. | Choose ST21NFCD for cost-sensitive consumer electronics where FeliCa and ISO/IEC 15693 are unnecessary. |
| PN7150B0HN/C1 | Lower power-down current (3 µA); no integrated self-test; supports only ISO/IEC 14443 A/B and NFC Forum Type 2/4; no MIFARE Classic support. | Targeted at portable devices and wearables; lacks automotive qualification and extended temperature validation. | Choose PN7150B0HN/C1 for battery-powered accessories requiring minimal quiescent current but not automotive-grade reliability. |
Compared with ST21NFCD and PN7150B0HN/C1, the NCF3340AHN/00301Y uniquely combines automotive temperature range (-40°C to +85°C), full multi-standard support (including FeliCa and ISO/IEC 15693), integrated antenna self-test, and NCI-compliant firmware - making it the only option qualified for safety-critical vehicle entry and diagnostics functions.

This range is validated across all electrical specifications including RF output, polling current, and NCI interface timing - ensuring reliable operation in real-world vehicle thermal environments without derating.
Does the NCF3340AHN/00301Y support FeliCa and ISO/IEC 15693 protocols?
Yes, the NCF3340AHN/00301Y fully supports FeliCa at 212 kbit/s and 424 kbit/s, and ISO/IEC 15693 for read/write operations. These capabilities are implemented in the embedded firmware and confirmed in the AUTONCF3340LF REV 0 datasheet - enabling compatibility with Japanese transit cards and asset tracking tags in automotive service tools.
What host interfaces does the NCF3340AHN/00301Y provide?
The NCF3340AHN/00301Y provides NCI v2.0-compliant I²C and SPI interfaces for host communication. Both interfaces support standard clock speeds (I²C up to 400 kHz, SPI up to 10 MHz) and are validated with AUTOSAR NCI stack, Linux NFC subsystem, and Android NFC HAL - allowing drop-in integration without custom low-level drivers.
Is the NCF3340AHN/00301Y pin-compatible with other NCx3340 variants?
No - the NCF3340AHN/00301Y uses the HVQFN40 package with wettable flanks, while other NCx3340 variants like NCJ3340AHN/00301Y share identical pinout but differ in temperature grade (-40°C to +105°C). Mechanical and electrical pin compatibility is confirmed across all NCx3340-AHN suffix parts, enabling shared PCB layout for multiple thermal grades.
What is the purpose of the integrated self-test feature in the NCF3340AHN/00301Y?
The integrated self-test verifies antenna circuit continuity and resonance during production test by injecting calibrated RF signals and measuring return loss. This function is executed autonomously by the embedded firmware and requires no host intervention - ensuring every NCF3340AHN/00301Y unit shipped has functional RF front-end before installation in automotive assemblies.
