What is the I/O output voltage of CC2640R2F? What is the decision?

The output voltage should be the same to VDD.

If VDDS and VDDS2 have different voltages, then the output voltage of I/O is the same as who.

Hi Hank,

This is documented in the datasheet and the Tehnical Reference Manual.

Cheers,
