99AFMX – INTEL

The Intel I226-LM, designated by part number 99AFMX, is a single-port Gigabit Ethernet controller primarily intended for embedded and desktop applications. It utilizes a PCIe 3.1 x1 host interface for communication with the system chipset. The controller supports IEEE 802.3 standards, including 10BASE-T, 100BASE-TX, and 1000BASE-T, enabling network connectivity at speeds up to 1 Gbps. Integrated features include checksum offload for TCP, UDP, and IP packets, reducing CPU utilization. It incorporates advanced power management capabilities, supporting Energy Efficient Ethernet (EEE) and other low-power modes to minimize energy consumption. The I226-LM typically interfaces with an external PHY transceiver to manage the physical layer signaling over Ethernet cabling. It supports Wake-on-LAN (WoL) functionality, allowing the system to be awakened from a low-power state via network activity.
