WebBut that USB chip is probably connected to the 5V rail. So it likely won't power up. That said, maybe you you don't need the USB in the context where you need to power from 3.3V. Make sure you have good regulation on the 3V line. It needs to be spot on 3.3V with ~500mA in-rush capability. Don't hook it up to a bare LiPo battery, for example. WebMay 6, 2024 · This limited current and the parasitic capacitance modify the signal waveforms. Depending on the exact capacitance of your circuit you may not achieve reliable communications with the Flash chip. The 10k resistor limits the maximum current to 0.5mA as the voltage at the tap point increase this drive current is reduced. for people having i225-v connection issues
