Write on an AS3953 EEPROM with my Arduino Uno board

Hello everyone,

In my project, I need to write data to an EEPROM. I am using the AS3953 memory and I have wired it in SPI to my Arduino Uno.
My question is : Do you have any information to share to help me? (programs, examples, website,...)
I already tried to do it with this website :
http://www.mon-club-elec.fr/pmwiki_reference_arduino/pmwiki.php?n=Main.ApprendreTutorielSpiEeprom

On the website example, it uses a different memory. But the AS3953 is similar I think.

Thanks for your help :wink:

The AS3953 is an NFC interface. Take another look at the markings on the chip.

I don't understand, my AS3953 is composed of an antenna and an EEPROM.
I am talking about this component:

The NFC interface does contain an EEPROM. Have you looked at the data sheet?
