CC2642R: GPIO to a Regulator EN Pin

David Tandri

Part Number: CC2642R
Other Parts Discussed in Thread: TPS63900,

Hi,

I am connecting one of the CC242R GPIO to TPS63900 EN pin. TPS63900 EN pin has VIL of 0.4V minimum and VIH of 1.2V maximum.

If I am supplying 3.3V to CC2642R, what is the range of VOL and range of VOH of CC2642R in order for the TPS63900 EN pin to intepret as LOW and HIGH respectively?

Please advise.

Thanks

See "5.13.6 GPIO" in the datasheet (https://www.ti.com/lit/ds/symlink/cc2642r.pdf) on the DIO specification for CC2642R

Hi,

I have referred to that table before.

I don't see any VOL and VOH for 3.3V MCU supply.

Thanks
