WGI210AT Présentation
A Gigabit Ethernet controller is a purpose-built networking IC that links a host processor (typically via PCIe) to a copper or fiber physical network, handling MAC/PHY framing, link training, and TCP/UDP/IP checksum offload. Within Intel's Ethernet controller taxonomy, the I210 sits in the lower-power mainstream tier below the I350/I210 server parts, optimized for single-port embedded and small-form-factor designs. PCIe is the standard host interconnect for these controllers, replacing the older PCI-X interfaces that preceded the GbE era.
Key features include TimeSync offload (IEEE 1588/802.1AS) for industrial automation, energy-efficient Ethernet (EEE) per IEEE 802.3az, jumbo frame support up to 9.5 KB, and the proven Intel PROSet driver stack. The exposed pad of the QFN-64 package provides a low-thermal-resistance path to the host PCB, a critical feature since GbE PHYs can dissipate 600 mW to 1.2 W during continuous full-duplex operation. On-die MACsec and VLAN stripping/insertion further reduce host CPU overhead.
Architecturally, the I210 uses a PCI Express 2.1 endpoint controller with one x1 lane, hardware IEEE 802.1Qav time-sensitive-networking shaping, and an integrated 1000BASE-T PHY capable of auto-negotiation across all three link rates. The MAC supports 9.6 KB jumbo frames, IPv4/IPv6 checksum offload, TCP segmentation offload (TSO v2), and iSCSI boot for SAN-attached storage platforms. This combination of MAC, PHY, and PCIe in a single 64-pin QFN distinguishes the I210 from external-PHY controllers.
Typical applications include industrial PCs, factory automation controllers, point-of-sale terminals, network printers, embedded routers, and small business servers. For automotive and industrial-grade designs with extended temperature requirements, Intel offers the pin-compatible WGI210IT variant rated for -40 C to +85 C operation rather than the 0 C to +70 C commercial range of the WGI210AT.
When designing with this controller, allocate at least four PCB layers with a continuous ground plane beneath the QFN-64 exposed pad to keep junction temperature below 110 C; provide 4 kV ESD protection on the MDI lines; and verify driver compatibility with your OS kernel (Windows, Linux, VxWorks, or RTOS). The PCIe reference clock must be a 100 MHz HCSL source with the impedance and jitter specified in the Intel I210 datasheet.

Applications typiques
WGI210AT convient pour 7 applications: Industrial PC and Factory Automation Gateway, Point-of-Sale (POS) Terminals and Retail Networking, Network Printers and Multifunction Devices, Small Business Routers and Network Attached Storage (NAS), Embedded Medical Imaging and Diagnostic Equipment, Industrial IoT Gateways and Edge Compute Appliances, Building Automation and Energy Management Controllers.
Industrial PC and Factory Automation Gateway
The WGI210AT's integrated 1000BASE-T PHY and PCI Express 2.1 x1 host bus deliver single-cable Gigabit uplink for industrial PCs, programmable logic controllers (PLCs), and SCADA gateways. IEEE 1588 TimeSync hardware time-stamping at the MAC gives sub-microsecond accuracy required for synchronized motion-control rings, while energy-efficient Ethernet (IEEE 802.3az) drops link power below 50 mW during idle periods. The 0 C to +70 C commercial temperature window covers most factory-floor enclosures; for harsher cabinets select the pin-compatible WGI210IT. Junction-to-ambient thermal resistance of about 28 C/W means a 4-layer ground plane beneath the QFN-64 EP keeps Tj below 100 C during continuous GbE traffic.

Point-of-Sale (POS) Terminals and Retail Networking
POS terminals and self-checkout kiosks benefit from the WGI210AT's single-port MACsec engine and preboot iSCSI remote-boot support, which lets a back-office server stream an OS image to each lane-side register. The 3.3 V/0.9 V dual supply simplifies integration with the small mixed-voltage rails typical of ARM-based POS boards, and the 9 x 9 mm QFN-64 footprint fits easily beneath the small-form-factor displays used in modern checkout hardware. Combined with the Intel PROSet driver stack and DTLE/WOL wake support, retailers can centrally manage registers and wake them for end-of-day reconciliation. The integrated PHY eliminates the EMI footprint of a separate 1000BASE-T transceiver.
Recommandé
Network Printers and Multifunction Devices
Office printers, multifunction devices, and label applicators use the WGI210AT as a single-chip Gigabit uplink to the office LAN, leveraging its 9.6 KB jumbo-frame support to push large PDF or PCL payloads at full line rate without tasking the printer's image processor. The on-chip PHY avoids a separate Ethernet magnetics section, and the WOL/preboot support lets the MFP wake from sleep on incoming print jobs, dropping standby draw toward zero. Deep-sleep EEE operation also meets ENERGY STAR imaging-equipment criteria. The single 3.3 V rail plus internal SVR simplifies the printer's multi-rail power design.
Recommandé
Small Business Routers and Network Attached Storage (NAS)
Small-business routers, branch-office firewalls, and 2- to 4-bay NAS enclosures use the WGI210AT as a WAN or LAN-side Gigabit port where board space, EMI, and BOM cost all matter. Hardware TCP segmentation offload v2 plus IPv4/IPv6 checksum offload shift multi-gigabit WAN throughput off the host CPU, and iSCSI boot turns the same controller into a SAN-attached storage initiator. The commercial 0 C to +70 C window suits typical office thermal envelopes; firmware upgradable via Intel's NVM Update Tool keeps deployed units patched against newly disclosed vulnerabilities. Single-port design drops BOM cost below multi-port alternatives.
Recommandé
Embedded Medical Imaging and Diagnostic Equipment
Ultrasound carts, patient monitors, and bedside imaging peripherals use the WGI210AT to push DICOM imaging files over the hospital network, where its hardware checksum offload and 9.6 KB jumbo-frame support maintain streaming throughput. The exposed-pad QFN-64 delivers about 28 C/W junction-to-board resistance so a 4-layer ground plane keeps Tj well below the 110 C medical-equipment safety margin. MACsec hardware encryption adds link-layer security without tasking the medical SoC. Where extended -40 C to +85 C operation is required, the pin-compatible WGI210IT is the industrial drop-in, sharing the same driver binary.
Recommandé
Industrial IoT Gateways and Edge Compute Appliances
Edge gateways aggregating Modbus, EtherCAT, or PROFINET fieldbus traffic onto an enterprise backbone benefit from the WGI210AT's IEEE 1588 hardware time-stamping and Time-Sensitive Networking shaping (802.1Qav), which let deterministic Ethernet and best-effort IT traffic share one wire. The single-chip MAC+PHY integration drops a typical edge-node BOM by $4 to $8 compared with discrete designs, and the on-die EEE state machine cuts idle draw below ENERGY STAR IoT thresholds. EAL2+ secure boot support via the iSCSI boot ROM helps meet IEC 62443 expectations. The commercial temperature window covers most edge enclosures.
Recommandé
Building Automation and Energy Management Controllers
Building automation controllers use the WGI210AT to bridge BACnet/IP, KNX/IP, and Modbus TCP traffic into the IP backbone, where its integrated 1000BASE-T PHY removes the cost of an external Ethernet transceiver. Single 3.3 V supply plus integrated SVR simplifies the 24 VAC-to-3.3 V power tree common in HVAC panels. Wake-on-LAN support allows remote firmware push during off-hours, critical for managing distributed rooftop units and lighting controllers. The pin-compatible WGI210IT variant supports -40 C to +85 C outdoor enclosures, sharing the same driver binary and PCB footprint.

Principaux différenciateurs
- Pin-compatible industrial-temperature variant in the same QFN-64 footprint (vs WGI210IT)
- Intel-recommended replacement for obsolete WGI211AT (vs WGI211AT (obsolete))
- Integrated 1000BASE-T PHY removes external magnetics/transceiver BOM (vs Discrete-MAC external-PHY controllers)
Notes de conception
Estimated: the WGI210AT draws about 0.7 W at full 1000BASE-T duplex, and the 9 x 9 mm QFN-64 exposed pad gives a typical theta_JA of about 28 C/W on a 4-layer JEDEC test board. Place a continuous, unbroken copper ground plane directly under the EP and stitch it to inner ground planes with a 0.3 mm thermal-via array (8 to 12 vias) so the device can dissipate sustained traffic without Tj exceeding 100 C. Without that ground pour the junction can climb 20 C higher under sustained load.
Route the 1000BASE-T MDI pairs as a 100-ohm differential bundle with intra-pair length matching to better than 0.13 mm to keep return loss within IEEE 802.3 limits. PCIe REFCLK+/- must be a 100 MHz HCSL source with the jitter and impedance specified in the Intel I210 datasheet section 5. Place the 0.1 uF + 1 uF + 10 uF decoupling cluster within 5 mm of the VDD3P3 and VDD0P9 balls, and reference all high-speed return currents to an unbroken ground plane.
Do not substitute the WGI210AT for an I225 or I226 controller on an I211AT board without re-laying the PCB; Intel PCN 118543-00 explicitly states I225/I226 are NOT pin-2-pin compatible with I211AT. When sourcing from non-authorized brokers, always verify the S-Spec code (S LJXR or S LJXQ) and the reel label - the Intel community has documented counterfeits stripped from scrapped motherboards and re-marked as new WGI210AT. Use Intel's electronic qualification kit to validate each lot.
Common-mode chokes on each MDI pair are required at the RJ45 magnetics to meet FCC Part 15 / EN55032 Class B limits. The integrated PHY's internal terminations reduce BOM cost but do not by themselves meet radiated-emission limits below about 200 MHz. A shielded RJ45 jack with the shield bonded to chassis ground lowers radiated emissions on the MDI bundle. Add a 100 MHz PCIe spread-spectrum clock to your root complex to widen the 5th-harmonic peak if radiated margins are tight.
