NFC Tag 2 Click - MikroElektronika Energy Harvesting NFC Type 2 Tag

NFC Tag 2 click carries the NT3H1101 NTAG I2C energy harvesting NFC Forum Type 2 Tag from NXP. The click is designed to run on a 3.3V power supply only. It communicates with the target MCU over I2C interface and the INT pin (field detection) on the mikroBUS™ line. 

NT3H1101 NTAG I2C and energy harvesting

NT3H1101 NTAG I2C - energy harvesting NFC Forum Type 2 Tag with field detection pin.

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 FD (field detection) LED is turned ON when an NFC field is detected. Power is generated from the RF field of an NFC device. For example, the NFC Tag 2 click can be powered by your mobile phone. This eliminates the need for an external power supply or a battery. 

At room temperature, NT3H1101 NTAG I2C could provide typically 5 mA at 2 V on the VOUT pin of NT3H1101 which is attached to the FD LED.

How it works

The NT3H1101 NTAG I2C which can be found on NFC Tag 2 click is the first product of NXP’s 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 NT3H1101 NTAG I2C is powered from an external power supply.

An additional externally powered SRAM mapped into the memory allows a fast data transferbetween the RF and I2C interfaces and vice versa, without the write cycle limitations of the EEPROM memory.
