82562 Family Platform LAN Connect Fast Ethernet Controllers

Intel® 82562 Family Platform LAN Connect Solution: Product Brief

The Intel® 82562 family of controllers are highly integrated Platform LAN Connect (PLC) devices combining 10BASE-T and 100BASE-TX physical layer capabilities and providing a core ingredient of the enabling solution for the integrated networking connectivity in Intel® I/O Controller Hub (ICH2/3/4) based platforms. Both support a single interface fully compliant with the IEEE 802.3/802.3u standard. The IEEE 802.3u standard for 100BASE-TX defines networking over two pairs of Category 5 unshielded twisted pair cable. The 82562ET and 82562EM comply with the IEEE 802.3u Auto-Negotiation (and 100BASE-TX) standard and the IEEE 802.3x Full Duplex Flow Control standard.

The combination 82562 device with ICH2/3/4 LAN solution enables a 32-bit PCI device that features enhanced scatter-gather bus mastering capabilities allowing high-speed data transfers over the PCI bus. In addition, these bus mastering capabilities enable the LAN solution to process high-level commands and perform multiple operations, thereby offloading communications tasks from the system CPU. Two large transmit and receive FIFOs are also included in the architecture to enhance performance while minimizing the use of system resources.

Target applications include but are not limited to LAN on Motherboard (LOM) and Communications and Networking Riser (CNR) form factors targeted at the value segment. These designs could include embedded and PC target applications requiring reliable 10/100 Mbps LAN capabilities. The 82562 family enables additional enterprise management capabilities beyond this baseline. When combined, the 82562, the 82562 software, and the embedded LAN capability in the ICH2/3/4 make up Intel’s newest high quality 10/100 Mbps network solution, the Intel® PRO/100 VE/VM Network Connection.
