NCF3320EHN is an NFC chip from NXP with the following functions and features1:
Communication Compatibility It is an NFC Forum compliant Type 5 tag, ensuring strong and reliable communication with NFC phones, which makes it suitable for a wide range of automotive applications.
It complies with the ISO/IEC 15693 standard, enabling seamless interoperability with other devices and systems that adhere to the same standard.
Memory Function It is equipped with 2048 bytes of user memory and 256 bytes of SRAM, providing sufficient space for storing various data and for temporary data processing and caching, which is convenient for the operation and management of different application data.
Wired Interface Configuration It offers configurable wired interfaces including I²C master and slave, GPIO, and NFC field detection. This allows for flexible connection and interaction with other components in the system, facilitating the realization of diverse functions such as data transmission, device control, and NFC signal detection.
Energy Harvesting It has an energy harvesting function with 32/64-bit configurable output, capable of reaching 30 mW. This feature enables the chip to collect and utilize ambient energy, improving energy efficiency and reducing power consumption in certain applications.
Security Features It provides expandable security capabilities, including 32/64-bit password protection, three configurable user memory areas, ECC-based reprogrammable original signature, and 128-bit AES mutual authentication. These security measures help protect data privacy and system security, making it suitable for applications that require high security, such as automotive access control and secure payment.
NFC Mute Function It has an NFC mute function to disable the NFC interface. This allows for flexible control of the NFC function according to different application scenarios and requirements, improving the security and stability of the system and reducing interference from external NFC signals when needed.
Low Power Consumption It has a low power consumption design, with a standby current of less than 6 μA and a hard power-off current of less than 0.25 μA. This helps to prolong the battery life of devices and is particularly suitable for applications where power consumption is critical, such as battery-powered automotive devices.
Wide Temperature Range It can operate in a wide temperature range from -40°C to +85°C, demonstrating excellent adaptability to different environmental temperatures. This makes it suitable for use in various harsh automotive environments and ensures stable performance in different seasons and regions.
