PSoC™ 6

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

The data sheet can be read as recommending applying a voltage of 1.7V to 3.6V, however the application note recommends floating.

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
