USB OTG HS
The STM3220G-EVAL evaluation board enables USB OTG high speed communication via a
USB Micro-AB connector (CN9), USB high speed PHY (U8) and USB power switch (U4)
connected to VBUS. The evaluation board can be powered by this USB connector (CN9) at
5V DC with a 500 mA current limitation.
The LED LD7 indicates that power switch (U4) is ON and STM3220G-EVAL is working as a
USB host or that VBUS is powered by another USB host when STM3220G-EVAL is working
as a USB device. The LD8 indicates an over-current.
The USB ULPI bus is shared with CAN2 bus, the JP10 and JP3 must be kept open for USB
OTG HS.
