USB Interfaces

The CoreModule 720 contains three root USB hubs and six functional USB ports. The PCH provides the
USB function including the following features:
•
Supports USB v.2.0 EHCI and USB v.1.1 UHCI
•
Provides over-current detection status
•
Provides a fuse on board for over-current protection
Table 3-6 describes the pin signals of the USB0 and USB1 header which consists of 10 pins, in two rows,
with odd/even (1, 2) pin sequence, and 0.079" (2mm) pitch.

to a logic 1 when no data is being sent.
2 COM1 Receive Data – Serial port receive data input is typically held at a
logic 1 (mark) when no data is being transmitted.
5 Ground
3 COM2 Transmit Data – Serial port transmit data output is typically held
to a logic 1 when no data is being sent.
2 COM2 Receive Data – Serial port receive data input is typically held at a
logic 1 (mark) when no data is being transmitted.
5 Ground
3 COM3 Transmit Data – Serial port transmit data output is typically held
to a logic 1 when no data is being sent.
