st25r3916 - st25r3916B compatibility

[pagano.paganino]

Hello,

I wanted some more clarification on the st25r3916B chip, it is very interesting as well as cheap compared to st25r3916 and covers my needs.

are they interchangeable? do they have pin to pin compatibility? the firmware has not yet been released or is it compatible with RFAL for ST25R3916?

thank you very much and greetings.

D.

Hi,

Please see AN5768. Existing RFAL on st.com in latest version already supports both devices by means of a compiler define S25R3916 vs ST25R3916B.
