​Dear Customer,

Our webpage https://www.st.com/en/nfc/m24sr-series-dynamic-nfc-tags.html has a lot of information that might be of interest to you

To start with the datasheet is available in https://www.st.com/resource/en/datasheet/m24sr64-y.pdf

and contains all the commands supported by M24SR.

Software is available on the Reader side and for Android, as well as source code for the I2C Master for different targets. The link is: 

 https://www.st.com/en/nfc/m24sr-series-dynamic-nfc-tags.html#tools-software

Finally application notes can be handy as well, and show examples of communication between a Reader and M24SR, or an I2C Master and M24SR.

https://www.st.com/en/nfc/m24sr-series-dynamic-nfc-tags.html#resource

I recommend in particular: AN4430 Designing an NFC Android Application for M24SR and M24LR devices

and AN4433 Storing data into the NDEF memory of M24SR

Have a good day.

Regards
