Four Ways the NTAG 5 Family Innovates NFC

With a tiny NFC antenna footprint and added AES security, these ultra-compact devices are enabled to securely interact with the cloud and other NFC-enabled devices for various use cases like pairing. The applications range across different segments like consumer, industrial, and IoT.

  1. The NTAG 5 boost reduces antenna footprint by a factor of 30
  2. Giving ultra-compact devices like hearables and wearables the ability to interact with other, NFC-enabled devices require a much smaller antenna size. With the unique features of the NTAG 5 boost, the antenna size can be reduced by a factor of 30 to fit in small devices without compromising the read range. Together with <10 µA current consumption in standby mode and 0.25 µA in hard power-down mode, the NTAG 5 boost fits perfectly into tiny battery-powered devices. With the use of active load modulation (ALM), an NFC bridge brings a new level of convenience to tiny devices as it yields robust and reliable communication with NFC phones and devices.

  3. The NTAG 5 I²C master – why you don’t need a µC to read out sensor data

    The NTAG 5 link does not need a microcontroller or a battery as it can be configured to act as an I²C master channel. The highly integrated NFC bridge – optimized for sensor-driven applications – creates a link from the device to the cloud. This feature is useful for a secure, future-proof way to read and power sensors instantaneously or to extend the needed EEPROM to your needs. The result is reducing the cost of material to a minimum by eliminating the MCU.

  4. The NTAG 5 has regulated energy harvesting capabilities

    The cost of materials for an application with an NTAG 5 link and switch can be further reduced by eliminating the battery. The NTAG 5 can harvest energy in two different modes. One of the modes is optimized for low field strength, e.g. NFC enabled mobile phones, and the other one is for high field strength when using a powerful NFC reader. Thanks to the energy harvesting feature, products can harvest regulated energy to supply any attached circuit up to 30 mW, thus eliminating the need for having batteries for every device.

  5. The NTAG 5 implements scalable security

    The NTAG 5 family addresses the security reservations of customers by providing scalable security levels based on different use cases and various customer needs. The 2048 bytes of memory in the tag can be divided into three areas in which each area can use a different protection level. The level of protection varies from no protection to 32-/64-bit password protection or up to 128-bit AES-protected read/write access with mutual authentication. This allows different parties in the value chain to have their own dedicated memory areas for storing access data. Also, the security level can be upgraded anytime during the lifetime of the product meaning that a customer can start with any security level (e.g. 32-bit plain password) and after some time change it to AES mutual authentication, by simply doing an “upgrade”.
