CP2102 USB pull-up current consumption

Question

I'm not sure, what the current consumption of the CP2102 is, when no USB is connected. In the datasheet it states:

And there is this USB pull-up specification. What does this mean? When no USB cable is connected, it draws around 200uA?

Ah i get it now, these currents are just from the pull-up. So the controller will always draw some decent amount. — HansPeterLoft, Commented Oct 13, 2020 at 8:29
The pull-up current is not consumed if USB cable is disconnected. — Justme, Commented Oct 13, 2020 at 8:55

I have found that the CP2102 doesn't always power down into suspend mode, so it draws 20mA even when the USB cable is disconnected.
