Communication ports
5.7.1. USB 2.0 HS
The ME910C1 includes one integrated universal serial bus (USB 2.0 HS) transceiver.
The following table is listing the available signals:
PAD Signal I/O Function NOTE
B15 USB_D+ I/O USB differential Data (+)
C15 USB_D- I/O USB differential Data (-)
A13 VUSB AI
Power sense for the internal
USB transceiver.
Accepted range:
3.0V to 5.5V
100K pull down
The USB_DPLUS and USB_DMINUS signals have a clock rate of 480 MHz, therefore
signal traces should be routed carefully. Trace lengths, number of vias and capacitive
loading should be minimized. The characteristic impedance value should be as close as
possible to 90 Ohms differential.
ESD protection can be added to USB D+/D- lines in case of external connector for cable
connection.
Proper components for USB 2.0 must be used.
