3.5 Ethernet Controller
MAC Type: PCH internal Gigabit Ethernet Media Access Controller
Manufacturer: Intel
Connection: RGMII
An Ethernet PHY is needed on the carrier board. A recommended device is the Realtek RTL8211CL
Gigabit Ethernet transceiver.
The data transfer between MAC and PHY is via the Reduced Gigabit Media Independent Interface
(RGMII) for 1000Base-T, 10Base-T and 100Base-T.
3.6 SATA Ports
There are 2 SATA (Serial Advanced Technology Attachment) Generation 2 (up to 3.0 Gbps) ports
provided by the PCH EG20T.
3.7 USB 2.0 Ports
The PCH EG20T provides 6 USB 2.0 ports and a USB client port.
3.8 Audio Interface
Only the HDA-LINK will be routed to the CoreExpress connector.
3.9 SDIO Interface
The PCH EG20T provides an 8 Bit SDIO interface.
3.10 CAN-Bus Interface
A CAN-bus 2.0B interface with up to 1Mbps is available. A transceiver is still needed to be placed on
the baseboard.
3.11 On Board Power Supply
The on board power supply generates all necessary voltages from the single supply voltage of 5 volts
DC.
3.12 External Power-Button
The board has a power button support to initiate transition from S4/S5 to S0.
