The NT3H1101W0FHK is a NTAG I²C, energy harvesting NFC forum Type-2 Tag with field detection pin and I²C interface. The NTAG family offering both contactless and contact interfaces. In addition to the passive NFC forum compliant contactless interface, the IC features an I²C contact interface, which can communicate with a microcontroller if the NTAG I²C is powered from an external power supply. An additional externally powered SRAM mapped into the memory allows a fast data transfer between the RF and I²C interfaces and vice versa, without the write cycle limitations of the EEPROM memory. The NTAG I²C product features a configurable field detection pin, which provides a trigger to an external device depending on the activities at the RF interface. The NTAG I²C product can also supply power to external (low power) devices (e.g. a microcontroller) via the embedded energy harvesting circuitry.
