An additional USB2.0 port is connected to an onboard header. This port is reserved
for custom use. Please contact your Advantech representative if you are interested to
use this port.
The USB Host Controller is integrated into the Atom C2000 SoC and implements a
Enhanced Host Controller Interface compliant to the EHCI 1.0 Specification. The
EHCI supports up to four USB 2.0 root ports. The controller integrates a Rate-Match-
ing Hub to support USB 1.1 devices. Universal Host Controller and Open Host Con-
troller Interfaces are not supported by the Atom C2000 device.
Please note that the BIOS of the FWA-2320 supports disabling the USB Controller as
well as specific USB device classes. Please refer to chapter BIOS / BIOS Setup
Menu for details.
2.4.5.2 SATA
The SoC has two independent integrated SATA host controllers. One controller sup-
ports DMA operation on up to four ports and supports data transfer rates of 3.0 Gb/s
(300 MB/s) and 1.5 Gb/s (150 MB/s) referred to as SATA2 controller.
The other controller, the SATA3 controller, in addition to legacy data rates supports
data rates of up to 6 Gb/s (600 MB/s). The SATA3 controller is the legacy IDE control-
ler and has two ports.
Both SATA controllers contains two modes of operation - a native mode and an AHCI
mode using memory space.
The SATA ports are implemented per below table on the FWA-2320. Other SATA
ports provided by the Atom C2000 are not used on the FWA-2320.
