The NCF3320 is an automotive-grade NFC transceiver from NXP designed for automotive secure access applications. In addition to combining high RF power output with strong multi-protocol support, it delivers outstanding low-power and card detection performance, making it an ideal choice for door handle applications.
Key Points
- Supports multiple protocols, including ISO/IEC 14443 A/B, FeliCa and ISO/IEC 15693
- Supports P2P passive initiator mode compliant with ISO/IEC 18092
- Wide RF chip driver voltage range with strong driver output current capability
- Enhanced wake-up (low-power card detection) mode ensures robust and sensitive card detection
- Antenna connection with a minimum of external components
Solution Overview
Our NFC card reader solution based on the NCF3320 uses the S9KEAZN64 as the main controller and supports LIN communication, allowing it to communicate with LIN nodes in the vehicle's electronic system to deliver NFC access control.
