Whether KW45 's VDD_RF PIN can be float if no use RF

[nicosuki]

we just want to use kw45 as a simple mcu only ,don't need RF function . Which components  can be deleted and Whether the VDD_RF pin can be Float? It would be nice to have a block diagram about how to config kw45 as a without RF.

Hi, @nicosuki 

I checked our KW45's datasheet, it mentioned that: 

VDD_RF

Supply voltage for OSC and radio analog

So it means, VDD_RF not only supply voltage for Radio analog, but also for OSC.

I do not recommend to float it even no use RF.

Hi, @nicosuki 

Will you use our KW45 to do COB designs? Or you will use our KW45-EVK in your project?

Best regards,

Christine.
