5.1.6
USB 3.0
The conga-TCA3 offers one USB SuperSpeed differential signal on the C–D connector. This interface is controlled by an xHCI host controller
in the SoC. The host controller allows data transfers of up to 5 Gb/s and supports SuperSpeed, high-speed, full-speed and low-speed USB
signalling. See section 7.3 "USB Port Mapping" for more information.
Note
The USB 3.0 port should be paired with USB 2.0 port 0 on the carrier board.
5.1.7
Gigabit Ethernet
The conga-TCA3 offers a Gigabit Ethernet interface on connector rows A–B via the onboard Intel
®
I210 Gigabit Ethernet controller. This
controller is connected to the Intel
®
Bay Trail SoC through the fourth PCI Express lane.
5.1.8
HDA Interface
The conga-TCA3 provides an interface that supports the connection of HDA audio codecs.
5.1.9
UART
The conga-TCA3 offers two UART interfaces. The interfaces do not support hardware handshaking and flow control.
Note
The onboard UART cannot be used in combination with an external, SuperIO based UART. They are mutually exclusive. The first UART is
implemented as a legacy compatible UART while the second is implemented as HSUART. The HSUART is not legacy compatible. Compared
with a legacy UART, it is limited in its feature set and requires a dedicated driver.
5.1.10
ExpressCard™
The conga-TCA3 supports the implementation of ExpressCards, which requires the dedication of one USB port and a x1 PCI Express link for
each ExpressCard used.
