Bringing The Advanced NFC Functionality To Healthcare, IoT, And Industrial IoT Applications

As one of the co-inventors of the NFC technology, NXP Semiconductors (NXP) is always bringing the most innovative NFC-related solutions to the market, targeting the broadest range of use cases. Recently, NXP introduced the NTAG 5 family, an NFC Forum Type 5-compliant family of NTAG devices, which combine NFC communication with a multi-purpose wired interface.

The TAG 5 family shares a set of common features among all members:

  • NFC Forum compliance
  • ISO/IEC 15693 standard compliance
  • Read Range Duality (powerful Industrial-grade readers up to 60 cm, and NFC-enabled device at close range)
  • Configurable wired interface: PWM, GPIO, Event Detection pin
  • Energy harvesting with configurable output voltage up to 30 mW
  • Scalable security
  • Three configurable user memory areas
  • ECC-based reprogrammable originality signature
  • Low power consumption: less than 6 μA standby, less than 0.25 μA hard power-down
  • Wide operating temperature range: -40 to +85 °C
  • Product support (dev board, app notes, software, hands-on training)

Rich with features and with many improvements over previous NTAG generations, the NTAG 5 family of devices enables some unique and innovative use cases in many different segments, including consumer, industrial, IoT, and healthcare. The NTAG 5 family of devices consists of three subcategories, each bringing one or more unique features on top of the common key features mentioned above:

  • NTAG 5 Switch, an NFC Type 5 Forum-compliant PWM and GPIO bridge for lighting and gaming applications
  • NTAG 5 Link, an NFC Type 5 Forum-compliant I2C bridge for IoT on demand
  • NTAG 5 Boost, an NFC Type 5 Forum-compliant I2C bridge for space-constrained applications

NTAG 5 Switch

NTAG 5 Switch (NTP5210) is an NFC Forum-compliant PWM and GPIO bridge. It can be used to replace the MCU in lighting or gaming applications, providing NFC-configurable PWM and GPIO features over its three-pin multipurpose wired interface. It also offers up to 512 bytes of password-protected non-volatile memory for various purposes.

As part of their product support, NXP offers the following development tools:

  • NTAG 5 Switch demo board for quick demonstration and evaluation purposes, using NFC Cube or an NFC-enabled smartphone (as part of the OM2NTA5KIT, a three-board Demo Kit)

NTAG 5 Link

NTAG 5 Link (NTP5312, NTP5332) is an NFC Forum-compliant PWM, GPIO, and I2C Bridge, optimized for sensor-driven applications. In addition to all the features found in NTAG 5 Switch, NTAG 5 Link brings the I2C functionality to its multi-purpose three-pin interface, as well as the additional 256 bytes of SRAM, larger EEPROM size, and a set of more sophisticated security features. NTAG 5 Link supports an NFC-compatible data exchange mechanism for IoT applications, enabling a convenient tap’n’go style user interface and easy management of IoT nodes with only an NFC-enabled smartphone.

  • OM2NTP5332, a development board equipped with Arduino® UNO pinout-compatible headers for rapid prototyping and development

NTAG 5 Boost

NTAG 5 Boost (NTA5332) is an NFC Forum-compliant PWM, GPIO, and I2C Bridge, which in addition to all the features found in the NTAG 5 Link, introduces an active load modulation (ALM) scheme for the RF front end. By utilizing an external power supply, the ALM allows for a significant antenna size reduction without compromising (or even boosting) the communication range. Thanks to the ALM feature, NTAG 5 Boost provides seamless NFC connectivity even for tiny, space-constrained devices and applications.

Summary

The NTAG 5 family from NXP extends the use of the traditional NFC solutions beyond applications in which they have become a de-facto standard. With the introduction of several new innovative features, the NTAG 5 family enters the domains of Industrial IoT (IIoT) and healthcare, bringing along the famous use simplicity that made it so popular in the consumer market.

If you’re looking for ways to refresh your design with a simple tap-n-go style interface while cutting down costs at the same time, the NFC 5 family from NXP might just be the right solution.
