USB Interface

The CoreModule 430 contains one root USB (Universal Serial Bus) hub and two functional USB ports. The
Vortex CPU provides the USB function including the following features:
•
Provides one root hub with two USB ports
•
Supports USB EHCI v.2.0 and USB OHCI v.1.1
•
Provides over-current detection status
•
Provides a fuse (F1, 1.5A) on board for over current protection
Table 3-8 describes the pin signals of the USB0 interface, which uses a single-row, 5-pin, right-angle header
with 0.100" (2.54mm) pitch.

7 Request To Send – Indicates serial port is ready to transmit data. Used as
hardware handshake with CTS for low level flow control.
3 Transmit Data – Serial port transmit data output is typically held to a
logic 1 when no data is being sent. Typically, a logic 0 (On) must be
present on RTS, CTS, DSR, and DTR before data can be transmitted on
this line.
8 Clear To Send – Indicates external serial device is ready to receive data.
Used as hardware handshake with RTS for low level flow control.
4 Data Terminal Ready – Indicates serial port is powered, initialized, and
ready. Used as hardware handshake with DSR for overall readiness.
9 Ring Indicator – Indicates external serial device is detecting a ring
condition. Used by software to initiate operations to answer and open the
communications channel.
5 Ground
NC Key Pin – Not connected
