1 General description
Optimized for sensor-driven applications, this highly integrated NFC IC creates a secure,
standard-based link from the device to the cloud, in a future proof way to address and
even power sensors.
NTAG 5 link is available in two different variants (see Section 4). NTP5332 supports all
features of NTP5312, and on top of these, it offers also I2C master features, as well as
AES mutual authentication.
NXP's NTAG 5 link lets designers of sensor-equipped systems add an NFC interface
with a wired host interface that’s configurable as an I2C master/slave, a pulse width
modulator (PWM), or a general-purpose I/O (GPIO). Operating at 13.56 MHz, it is an
NFC Forum-compliant Type 5 Tag (customer development board is NFC Forum certified
- Certification ID: 58626) that can be read and written by an NFC-enabled device at close
range and by an ISO/IEC 15693-enabled industrial reader over a longer range.

The NTAG 5 link can act as a direct bridge between an NFC-enabled device and any I2C
slave, such as a sensor or external memory. This is especially useful in environments
that require zero-power, single-shot measurements.
With NTAG 5 link, the device can connect to the cloud with a single tap. The connection
uses an NFC Forum-compliant data exchange mechanism involving SRAM to ensure
highly interoperable data transfers.
Support for ISO/IEC 15693 lets the NTAG 5 link communicate securely in two ways: with
powerful industrial readers, at a range of up to 60 cm and with NFC-enabled devices
in proximity range. This duality makes it possible for the device to be calibrated and
parameterized automatically while in the factory and then, when put to be used in the
field, safely communicate with contactless devices such as mobile phones.
NTAG 5 link offers 2048 bytes (16384 bits) bytes of memory which can be divided
into three areas, and each area can use a different protection level, varying from no

protection to 32-/64-bit password-protected read/write access or up to 128-bit-AES
mutual authentication protected read/write access.
The NTAG 5 link comes with pre-programmed proof-of-origin functionality to verify
authenticity. The ECC-based originality signature can be reprogrammed or locked by the
customer.
The NTAG 5 link can operate without a battery by drawing power from the NFC reader
instead. It supports energy harvesting, which means it can be used to supply power to
other components in the system. When sufficient energy is available, NTAG 5 link can
supply a fixed, configurable voltage level to ensure a stable overall system.
