Product details

What this NXP interface IC does on the board

The NXP TDA8035HN/C2/S1J is a specialized analog interface IC in a 32-HVQFN (5x5) package, designed for applications that need a clean analog signal path between a host controller and a smart card or similar contact-based interface.

If your design runs a 3.3V core logic rail, this IC operates directly from it. If you are retrofitting a legacy 5V system, it works there too. No level-shifting or extra regulator needed between the interface and the host, which saves board area and BOM cost. For a repair bench, this means the TDA8035HN/C2/S1J can drop into a board originally designed for a 5V-only interface chip without re-spinning the power supply.

Frequently asked questions

Is TDA8035HN/C2/S1J compatible with ISO 7816 smart card interface?

The part is described as a specialized analog interface IC, and its supply range and package are consistent with smart card interface applications, but the evidence does not explicitly state ISO 7816 compliance. Verify against the NXP datasheet for protocol-level compatibility.

Can TDA8035HN/C2/S1J operate at 3.3V?

Yes. The supply range is 2.7V to 5.5V, so 3.3V is well within the operating window.
