Engineering Brief

NTAG 5 Link is a dual-interface NFC tag IC that bridges contactless NFC communication (ISO 14443-A and ISO 15693) with I2C host connectivity, enabling battery-free IoT sensor applications. The chip features 2 kB of EEPROM for sensor data storage, energy harvesting capability to power external sensors from the RF field, and AES-128 cryptographic security for data protection. Its unique dual-protocol support allows both short-range (Type 2) and longer-range (Type 5) NFC reading, making it ideal for sensor data collection in retail, logistics, and industrial monitoring applications where battery-free operation is essential.

Frequently Asked Questions

What makes the NTAG 5 Link different from other NTAG chips?

NTAG 5 Link features dual-interface capability combining NFC communication (ISO 14443-A and ISO 15693) with I2C connectivity to host sensors, plus energy harvesting to power external components from the RF field. This makes it a bridge between contactless readers and battery-free IoT sensors, unlike standard NTAG chips which are NFC-only.

How much memory does the NTAG 5 Link have?

The NTAG 5 Link provides 2 kB (2048 bytes) of EEPROM user memory for storing sensor data and application information.

Does the NTAG 5 Link support both short-range and long-range NFC reading?

Yes, NTAG 5 Link supports both ISO 14443-A (NFC Forum Type 2, short-range) and ISO 15693 (NFC Forum Type 5, longer-range) protocols at 13.56 MHz, allowing flexible read distances depending on application requirements.

What security features does the NTAG 5 Link offer?

NTAG 5 Link includes AES-128 encryption for data protection, 32-bit password protection, UID ASCII mirroring, and SUN (Secure Unique NFC) message authentication for anti-counterfeiting and secure data exchange.

Can the NTAG 5 Link power external sensors without a battery?

Yes, NTAG 5 Link features energy harvesting capability that extracts power from the 13.56 MHz RF field to operate external sensors connected via I2C, enabling fully battery-free IoT sensor applications.

What is the I2C interface on the NTAG 5 Link used for?

The I2C interface allows the NTAG 5 Link to connect to external host devices such as microcontrollers or sensors, enabling the chip to act as a bridge that shares data between I2C-connected components and NFC readers.
