NTAG I²C – Energy harvesting NFC Forum Type 2 Tag

Offering both contactless and contact interfaces, the NTAG I²C is the first product of NxP’s NTAG family. The IC features an I²C contact interface which can communicate with a microcontroller if the NTAG I²C is powered from an external power supply, in addition to the passive NFC Forum compliant contactless interface.

The NTAG I²C product can also supply power to external (low power) devices (e.g. a microcontroller) via the embedded energy harvesting circuitry. It also features a configurable field detection pin, which provides a trigger to an external device depending on the activities at the RF interface.

Contactless and contact system

Why Used

  • 64 byte SRAM buffer for fast transfer of data (Pass-through mode) between the RF and the I²C interfaces located outside the User Memory
  • Energy harvesting functionality to power external devices (e.g. microcontroller)
  • FAST READ command for faster data reading
  • Data integrity of 16-bit CRC, parity, bit coding, bit counting
  • True anticollision
  • 64 bytes SRAM volatile memory without write endurance limitation
