The Intel® 82579LM family of Gigabit Ethernet Controllers provides compact, single-port integrated physical layer devices that connect to the Intel® 6 Series Express chipsets.
The Intel® 82579LM family of Gigabit Ethernet Controllers provides compact, single-port integrated physical layer devices that connect to the Intel® 6 Series Express chipsets. The 82579LM family of products are gigabit copper networking components for mobile, desktop, workstation, embedded and value-server designs that have critical space and power constraints.
Reduced Power and Energy Savings:
The Intel® 82579LM family reduces the power consumption in all power states compared to previous generations of Intel controllers. While in active-idle Intel® has implemented Energy Efficient Ethernet (EEE), a new IEEE standard. With EEE Intel has reduced the idle power of the gigabit link from about 500 mW to nearly 50 mW providing a significant energy savings. For mobile designs, Intel’s Auto Connect Battery Saver can help reduce the cable-disconnected power of the chip to about 30 mW while still maintaining full functionality. The products also support advanced link downshifting capabilities to provide additional power headroom for system regulatory compliance (such as Energy Star) by lowering the link speed under certain conditions to save power.
Intel® Business Client Features: The Intel® 82579LM supports Intel® AMT2, which is a part of Intel’s vPro™ technology on notebooks, desktop, and workstation systems. Intel vPro technology provides built-in manageability, proactive security, and energy-efficient performance for business applications.
Simplified installation and Maintenance: Intel® 82579LM products also support the Intel Stable Image Platform Program (SIPP), which provides system image stability (both hardware and software) and consistency for at least 12 months from the product launch date. Helping IT better manage their client environment.
Performance-Enhancing Features: Each of the Intel® 82579LM family of network components includes advanced interrupt-handling features to reduce CPU over-heard. Other erformance-enhancing features include offloading TCP/UDP (for both IPv4 and IPv6) checksum calculations and performing TCP segmentation. Advanced features such as Jumbo Frame support for extra-large packets and Receive Side Scaling are also supported.
Advanced Security: The Intel® 82579LM supports the latest Ethernet security standard known as MACsec3 (IEEE standard 802.1ae). MACsec provides robust security at a low level of the system by providing MAC layer (layer 2) encryption and authentication capability hop-by-hop. This enables IT to fully encrypt network traffic, but still perform traffic shaping and analysis at the router and doesn’t interfere with existing network protocols.
Flexible, Low-Cost System Design: The Intel® 82579LM family of networking components provide a small package (6x6 mm) networking option for convenient board layout. The Intel® 82579LM has flexible power options including sharing the 1.05 Vdc supply with the chipset or it can be configured using the integrated switching voltage regulator (iSVR), emoving the need for an external regulator and reducing overall cost and board space. Additionally, the 82579LM family of products help to reduce board space by using a shared FLASH design. Finally, low thermal design power (TDP) helps improve board placement flexibility.
Environmentally friendly design: The Intel® 82579LM family of products are all lead free4 and halogen free5 in their silicon and package design to reduce the potential for environmental impact.
