Hi,

I wish to know please if using this memory is there any way to access, via RF, the information that I stored via I2C. Or is the information separated, via I2C (2048 bytes) and via RF (512 blocks of 32 bits) , with no possible interaction between them?In alternative, to access the entire memory information, by using one or the other interface, should I use instead the M24SR16-Y version?Thank you very much.Regards #i2c-access #m24lr16e-r-dual-eeprom #m24lr16e

Hi ,

I want to know if this AN can help you

The EEPROM memory is shared between i2C & RF. Only difference is it is addressed. For example, bytes at the address

0000 0001 0002 0003

  in i2C are the same than 4 bytes at the RF block 0000. Have a nice day, ST NFC/RFID Dynamic tag support
