GD82551IT

The Intel GD82551IT is a highly integrated Fast Ethernet controller from Intel, combining a 10/100 Mbps media access controller (MAC) and physical layer (PHY) transceiver in a single BGA package. Designed for PCI-based systems, the device supports 32-bit bus master data transfers and auto-negotiation for seamless connectivity across twisted-pair copper networks, while its low-power architecture and advanced power management states enable efficient operation in thermally constrained embedded environments.

Typical deployments include industrial single-board computers, embedded network appliances, legacy aerospace avionics interfaces, and defense communication modules where proven PCI Ethernet connectivity remains essential. The BGA footprint suits space-constrained designs, and the controller’s deterministic performance characteristics meet the reliability demands of high-availability systems. When sourcing this component, procurement teams should evaluate long-term availability given the maturing lifecycle of Intel’s PCI Ethernet controller portfolio, verify authenticity from authorized channels, and consider lifetime buy strategies for system sustainment in military or industrial programs that require extended production support.
