Hi Experts,
Our customer has a question about the CC2531.
If the USB module is not currently being used, can the VUSB be left Open or must it be tied to +3.3V?
Also, if Vusb does not have to be tied to +3.3, should it be pulled down through a resistor?
We saw this E2E post below:
(+) CC2531 - unused USB - Other wireless technologies forum - Other wireless - TI E2E support forums
In this thread the user asks if it is OK to ground all of the USB pins (including the DVDD_USB pin), not leave it open. As a matter of fact, it raises the question of whether or not the USB_P, USB_N, as well as the DVDD_USB pins can be left unconnected?
We hope to receive your confirmation. Thank you.
Best regards,
Gerald
