2X Gigabit Network Performance for Desktops and Workstations
The Intel® 82547EI Gigabit Ethernet Controller enables full-duplex Gigabit Ethernet performance in your LAN on Motherboard (LOM) applications using groundbreaking Communication Streaming Architecture (CSA). A generation ahead of other Gigabit controllers, the Intel 82547EI Gigabit Ethernet Controller bypasses the PCI bus, freeing its bandwidth for other I/O operations, and connects to the dedicated CSA bus on the Memory Control Hubs (MCH) of the Intel® 865 and 875 chipsets for the Intel® Pentium® 4 processor. The CSA port architecture is invisible to both system software and the operating system, allowing conventional "PCI-like" configuration. CSA offers lower memory latency and higher performance than PCI-based controllers, giving the end-user a true Gigabit networking experience.

The Intel 82547EI Gigabit Ethernet Controller enhances secure manageability and system health monitoring over the LAN with support for IPMI 1.5, ASF 2.0 and Advanced Pass Through. For IPMI designs, the on-board SMBus port can pass management traffic through the controller to a management device, such as a Baseboard Management Controller (BMC) responsible for management functions. Alternatively, ASF 2.0 provides manageability without the cost burden of external hardware via standardized interfaces. ASF 2.0 circuitry provides advanced system health and security alerting plus authenticated remote power control capabilities.

The Intel 82547EI combines Intel's fifth-generation Gigabit MAC design with fully integrated physical-layer circuitry (PHY) to provide a standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX and 10BASE-T applications. Packaged in a 15x15mm PBGA, the Intel 82547EI Gigabit Ethernet Controller is footprint-compatible with the Intel® 82562EX and 82562EZ devices. Footprint-compatibility and Intel SingleDriver technology allow for a flexible Gigabit Ethernet or Fast Ethernet implementation on the same motherboard layout.

The Intel 82547EI Gigabit Ethernet Controller, coupled with the Intel 865 and 875 chipsets, enable full-duplex Gigabit networking performance for LOM designs using CSA with enhanced management capabilities and design flexibility.
