Introduction

NTAG 5 boost uses active load modulation (ALM) to deliver robust and reliable communication with NFC phones, bringing a new level of convenience to tiny devices. It shrinks the NFC footprint while adding AES security, so designers can deliver ultra-compact devices for use in IoT, consumer, and industrial applications. It offers an NFC Forum-compliant (customer development board is NFC Forum certified - Certification ID: 58625) contactless interface that delivers exceptional read range, giving tiny devices the ability to interact with the cloud and other NFC-enabled devices, including smartphones. ALM allows construction of a compact yet highly reliable antenna, creating a significantly smaller footprint without compromising the read range. When operating in ALM mode, the read range is significantly longer than when operating in passive mode. An energy-efficient design, equipped with a hard power-down mode and a standby current of typically less than 10 μA, ensures long battery life. 2048 bytes (16384 bits) of user memory can be divided into three areas, and each area can use a different protection level, varying from no protection to 32-/64-bit password protection or up to 128-bit AES-protected read/write access with mutual authentication. Different parties in the value chain can have their own dedicated memory areas for storing access data. The NTAG 5 boost comes with pre-programmed proof-of-origin functionality to verify authenticity. The elliptic curve cryptography (ECC) based originality signature can be locked or reprogrammed by the customer. With NTAG 5 boost, the device can connect to the cloud with a single tap. The connection uses an NFC Forum-compliant data exchange mechanism involving 256 bytes (2048 bits) SRAM to ensure highly interoperable data transfers.
