Intel Ethernet Controller I210-AT
Single-port Gigabit Ethernet controller IC for PCIe-based motherboard and adapter designs. This is a controller/chip record; finished-card details are implementation-specific.
IDENTIFICATION: Match complete component top-mark, stepping and board revision. Nominal signaling rates are not measurements of application throughput.
Exact specifications and compatibility
| Dedicated subcategory | Ethernet controllers and PHYs |
|---|---|
| Exact controller identity | Intel Ethernet Controller I210-AT |
| Component / board identity | Controller IC with integrated 10/100/1000 Ethernet MAC/PHY; board supplies RJ-45 and magnetics. |
| PCIe bus and host interface | PCI Express 2.1 x1 host interface. |
| Ethernet ports / physical interface | One 10/100/1000BASE-T twisted-pair Ethernet port; link partner negotiation and cable determine the negotiated rate. |
| Nominal rate (not measured) | Up to 1 Gb/s nominal on one port; not measured throughput. |
| Drivers and OS compatibility | Linux igb driver; Intel/OEM Windows Ethernet driver packages support selected versions. Confirm PCI ID, OS release, board NVM and OEM support list before deployment. |
| Board / system compatibility | Requires an I210-AT-compatible host board with PCIe x1 routing, clocks, power, NVM and the analog/magnetics layout specified by Intel. The IC alone is not an add-in NIC. |
| Revision and variant warning | I210-AT is a copper PHY/controller variant. Do not conflate it with I210-IS or a retail I210-T1 board; packages, temperature range and board design differ. |
| Measured throughput | No measured benchmark is claimed for a physical specimen. A valid result records the host, link partner, medium, driver/firmware, traffic pattern, test tool and duration. |

Archival and preservation notes
Photograph the package top mark and board silkscreen; record stepping, PCI vendor/device/subsystem IDs, NVM and the exact OEM driver package.
For an installed specimen, preserve source URL, access date, source revision and label/condition notes. Do not infer connector count or board-level compatibility from controller family name alone.
