hi , No, this is not yet possible with coreNFC to emulate iphone as a NFC Tag. The HostCardEmulation mode is ONLY reserved for Wallet applications (ApplePay, CarKey, ...) and is not accessible at user level. good luck.

Hi , I agree with Micke_S : The M24LR16E (and M24LR64E) requires 2 bytes to code the block address in the Read Single block command, which is not standard. So, I don't think that coreNFC will implement this as it follows the standard. Moving to ST25DV16 is the solution.
