The NT3H1201W0FHK is a NTAG I2C energy harvesting NFC forum type 2 Tag with field detection pin and I2C interface. 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 via the embedded energy harvesting circuitry.
- Configurable field detection pin based on open drain implementation
- Wake-up signal at the field detect pin
- Clear arbitration between RF and I2C interface
- Energy harvesting functionality to power external devices
- FAST READ command for faster data reading
