NXP NTP53121G0JHKZ

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. NTP5332 supports all features of NTP5312, and on top of these, it offers also I²C (overline) master features, as well as AES mutual authentication. It 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 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.
