Universal Serial Bus (USB) Controller
The Stellaris^® USB controller electrical specifications are compliant with the Universal Serial Bus
Specification Rev. 2.0 (full-speed and low-speed support). Some components of the USB system
are integrated within the LM3S5G31 microcontroller and specific to the Stellaris microcontroller
design. An external component resistor is needed as specified in Table 25-31.

Current Consumption
This section provides information on typical and maximum power consumption under various
conditions. Unless otherwise indicated, current consumption numbers include use of the on-chip
LDO regulator and therefore include I_DDC.
Nominal Power Consumption
The following table provides nominal figures for current consumption.
