Do not use ISO7816/14443 interface in SE050

Dear NXP team,

We will use SE050 for our new product.

However, our product does not use ISO7816 and ISO14443 Interfaces.

ISO_14443_LA

ISO_14443_LB

ISO_7816_RST

ISO_7816_CLK

ISO_7816_IO

ISO_7816_IO2

How should these pins be terminated?

Best Regards,

George

Hello George,

If not used, ISO7816 interface tied to VCC and ISO14443 interface tie to GND.

Hope that helps,

Have a great day,
Kan

Dear Kan_Li,

Thank you for your quick reply.

Is my understanding correct below?

And is the Pull Up/Down value about 10k-ohm appropriate?

BR,

George
