ST25R300 Integrated Oscillator possible?

Hi,

I would like to know if it is possible to use another oscillator source other than a crystal for the ST25R300?

I saw another post for the ST25R3911B, Is it possible to use a Clock Oscillator instead of Quartz crystal oscillator?, although obviously this is not the same chip I would like to use.

On the ST25R300 I do see there is a test register I can access, but I don't see any details on using an external oscillator.

Would a similar setup be possible for this chip?

Thank you, Kaitlyn

Hi KRauccio,

 

For the ST25R300 it is not foreseen to use something different than a quartz crystal oscillator.
