Table 3-5 describes the pin signals of the serial 2 header (J11), which consists of 10 pins, two rows, odd/even
(1, 2) pin sequence, and 0.079" (2mm) pitch
Note: The shaded table cells denote ground.
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.

Table 3-6. USB0 and USB1 Interface Pin Signals (J12)
Pin # Signal Description
1 USB-PWR_0 USB0 Power – VCC (+5V +/-5%) power goes to the port through an on
board fuse. Port is disabled if this input is low.
2 USB-PWR_1 USB1 Power – VCC (+5V +/-5%) power goes to the port through an on
board fuse. Port is disabled if this input is low.
3 CONN_USB0_N USB0 Port Data Negative
4 CONN_USB1_N USB1 Port Data Negative
5 CONN_USB0_P USB0 Port Data Positive
6 CONN_USB1_P USB1 Port Data Positive
7 USB_GND0 USB0 Ground
8 USB_GND1 USB1 Ground
