I’m very confused about the FCC regulation regarding the NTAG 5 Link when using it with a microcontroller.
If we take the NTAG I2C OM5569 Board as a reference, it clearly has an FCC-ID number (OWROM5569-NT322E), but the letter of conformity states that this board is considered an intentional radiator. Is it really the case even if you’re using a passive tag?
Now, referring to the AN12428 document for the NTAG 5, it states “NXP Semiconductor declares that this device is an FCC Class A unintentional radiator”.
Why is it that the NTAG5 is an unintentional radiator and the NTAG I2C is intentional?
Is the NTAG5 required to undergo any FCC certification if used with a microcontroller?
Thanks !
