Ethernet
The Intel® Ethernet Controllers i210 and i211, both support one Gigabit Ethernet connectivity. Which Ethernet
controller is implemented depends on COMe-mAL10’s chosen temperature grade. Both Ethernet controllers include
physical layer (PHY) ports supporting Ethernet media dependent interfaces [0-3].
The following table lists the supported Ethernet features.

Ethernet Controller
Intel ® i211AT Ethernet controller (for commercial temperature grade)
Intel® i210IT Ethernet controller (for industrial temperature grade)
Some additional features of the Intel® i210 and i211 Ethernet controllers are:
Energy Efficient Ethernet (IEEE 802.3az)
Jumbo frames (up to 9 kB)
Interrupt moderation, VLAN support, IP checksum
RSS and MSI-X to lower CPU utilization in multi-core systems
Advanced cable diagnostics, auto MDI-X
Error correcting memory (ECC)
IEEE1588/802.1AS precision time synchronization for Time Sensitive Networking (TSN) applications

COMe High-speed Serial Interfaces Overview
High-speed serial interfaces, including PCI Express Gen. 2.0, USB 3.0, SATA Gen.3 and 1 Gb Ethernet are available on
the COM Express® 220-pin connector. The following table provides an overview of the relationship between the COM
Express® connector ports and the SoC high-speed I/O ports.
The following table lists the possible high-speed serial interface combinations.
