Product details
Overview
NCJ3340EHN/00350Y from NXP is an automotive-qualified NFC controller with integrated ARM® Cortex®-M0 core, NCI-compliant I²C/SPI host interface, and full NFC Forum compliance for ISO/IEC 14443 A/B, FeliCa, MIFARE, and NFC Forum tag types - enabling secure driver authorization and vehicle diagnostics in automotive ECUs.
For engineers reviewing the NCJ3340EHN/00350Y datasheet, NCJ3340EHN/00350Y pinout, NCJ3340EHN/00350Y application, or NCJ3340EHN/00350Y equivalent, key selection considerations include its -40°C to +105°C operating range, HVQFN40 package with wettable flanks, <1 mW polling power, embedded NCI firmware, and support for all three NFC operating modes (Read/Write, P2P, Card Emulation).
Technical Context
The NCJ3340EHN/00350Y implements NFCIP-1 and NFCIP-2 protocols for peer-to-peer communication and supports ISO/IEC 14443 A/B at up to 848 kbit/s, FeliCa at 212/424 kbit/s, and ISO/IEC 15693. Its integrated ARM Cortex-M0 enables configurable polling loops and active load modulation without external microcontroller intervention.
It operates with dual supply domains: 1.8 V or 3.3 V pad voltage for digital logic and 2.7–5.5 V RF driver voltage delivering up to 170 mA peak current. Power management includes hard power-down mode (10 µA typ), RF-level-detector-enabled standby (20 µA), and low-power card detection (200 µA).
