USB
The XMC4200 supports USB interface in device mode. The power is expected through VBUS (pin 1) from an
external host (e.g. PC). When the current consumption of the application running on the Hexagon Application
system is higher than 500 mA, power from an external source through satellite cards shall be used.
Note: Some PCs, notebooks or hubs have a weak USB supply which is not sufficient for proper supply. In this
case use an external 5 Volt power supply or a powered USB hub.
The VBUS function can be mapped to the HIB_IO_0 pin. A voltage divider (R205/R206) limits the voltage level
at the HIB_IO_0 to maximum 3.3V.
