Part Number: CC2640R2F

Hello,

Just to make sure, is V_eb the only source for the entire CC2640R2F 5x5 designated board?

Is V_eb supposed to be in the range of 1.8V to 3.8V just like the CC2640R2F chip?

Will a 3V coin battery as supply should be good there?

Thanks,

Amit

VDDS is the supply going directly to the chip. A bead is placed between VDD_EB and VDDS to suppress noise on the supply. From this VDD_EB can have the same range as the CC2640R2 it self.

Yes, a coin cell is one possibility as power source.

I meant: the battery is supposed to be connected to V_eb, right?
