USB operation at 5V selfpower  in CY3664

Question: How to make USB work at 5V self power on the CY3664 kit?



To make your design work at 5V, please select the power settings of the device as 5V/24MHz in the device editor. Also, please start the USB as USB_5V_OPERATION in main.c.

If your design has the USB operating at 5V, please power the encore3 DVK board (CY3664) using the Miniprog and do not place any jumper on P3.


Please go through the encoreIII board schematics to know the location of the jumpers.
