Question about VDDD, USB, and Programming
I'm working on a layout that is using a PSOC5LP. I'd like to run the PSOC5LP off 3.3V but still provide a USB interface with computers. With VDDD hooked to 3.3V, I'll have to set the USBUART block to run in 3.3 mode, is there anything I have to hook up externally to the USB pins to make it work with a computer? If VDDD is set to 3.3V and I use a 5V computer USB input, am I destined to destroy the PSOC?
Thanks for the help in advanced,
