Dear Sirs and Madams,
I'm reviewing the datasheet, TRM and application notes to review the PSoC6 hardware.
Which is recommended for handling the VDDUSB terminal when the PSoC 6 USB is not used?
1. Page 38 of PSoC6 MCU : CY8C61x6, CY8C61x7 datasheet
https://www.cypress.com/file/385931/download
2. Page 4 of AN218241
https://www.cypress.com/file/385701/download
The data sheet can be read as recommending applying a voltage of 1.7V to 3.6V, however the application note recommends floating.
Regards,
Solved! Go to Solution.

If USB pins are not used as USB Dp/Dn or GPIOs -> Floating
If USB pins are used as GPIOs -> 1.7V to 3.6V
