Hello!

We have this chip, see in image. We think this is ST33Gххх in package UFDFN8 4.2 × 4 mm.

This is from NFC interface. The main question is that what is this chip model?

And the second question is, i dont found pins names in ST33G documentation.

    Welcome, @DMina.1​, to the community!

    For security chips, detailed information is understandably not publicly available.

    If necessary, the nearest distributor or ST office can help you if you provide them with your project details.

    The NFC coil was connected to the 1st and 8th pins.
