Hi. cypress

customer use CY7C65642 to design in two ports HUB(current pending 2ports). according to newly datasheet, I will let customer modify  R121 650R to 649R.customer use VUBS 5V to supply the IC, whether the SELPWR(Pin 22) to connect with VBUS or without any GND or VDD? do you have any other advice base on schematic.

thanks

Hi Flance,

SELFPWR pin can be connected to GND if there are no external power supply in customer's design.
