Question: In the FX2/FX2LP datasheet, Icc is specified when connected to USB FS and USB HS. What is Icc if the FX2/FX2LP is connected to neither? (e.g. just using the 8051 with a power supply)
Answer:
If the FX2 comes up without a USB cable attached, Icc would be 90mA (typical) for FX2 and 35mA(typical) for FX2LP. The full-speed transceiver is still turned on even if the USB cable is not attached, so the Icc specs would be for connected to USB FS.
