Can I change NFC detecting range on CLRC663 ?

cjujh — Fri, 08 Mar 2019 05:08:40 GMT

Hello.

I've been making NFC module using CLRC663 IC on CLEV6630B v2.0 Board nowadays.

I'd wanted to change the NFC detecting range by only use software setting.

So I'd checked datasheet and modified below register and 0x28 and 0x2A registers too.

But, it was operated same range.

Is it possible to change the range? How can I do that?

Thank you.

I am sorry, but the operating range depends on the antenna size, please refer to the following for details.

You may refer to NFC Antenna Design 1: Which Antenna for what purpos|NXP for more details.

Hope that helps,

Have a great day,
Kan
