I'm using FX3
I have to develop board with 3.3V supply.
Can I connect it to Vbatt ?
I read datasheet that Vbus has to be greater than 4.1V.
Yes, Vbatt can be 3.3. Please check the hardware guidelines for more information. Link: AN70707 - EZ-USB® FX3™/FX3S™ Hardware Design Guidelines and Schematic Checklist | Cypress Semiconductor
