INTERFACING ATTINY85 AN NTAG I2C PLUS (NT3H2111)

[Robert11]

hi, In my project, my microcontroller(attiny85 -master) send ndef formated data to nt3h2111 eprom(slave) through i2c  .when there is nfc field by mobile , the data is shared to mobile device. External power supply is given to both microntroller and nt3h2111 ic (energy harvesting is not required). For this case, whether field detection pin is required or not?

Hi

FD pin is used to notify the host some events happened.  Whether it is used or not depends on your application requirements.
