Product data sheet
1 General description
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.
NXP’s NTAG 5 boost 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,

Figure 1. NTAG 5 boost overview
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.
