GENERAL DESCRIPTION
The Realtek RTL8139C(L)+ is a highly integrated and cost-effective single-chip Fast Ethernet controller that provides 32-bit performance, PCI bus master capability, and full compliance with IEEE 802.3u 100Base-T specifications and IEEE 802.3x Full Duplex Flow Control. It also supports Advanced Configuration Power management Interface (ACPI), PCI power management for modern operating systems that is capable of Operating System Directed Power Management (OSPM) to achieve the most efficient power management. In addition to the ACPI feature, the RTL8139C(L)+ also supports remote wake-up (including AMD Magic Packet, LinkChg, and Microsoft wake-up frame) in both ACPI and APM environments. When auxiliary power is on and the main power remains off, the RTL8139C(L)+ is ready and waiting for the Magic Packet or Link Change to wake the system up. Also, the LWAKE pin provides 4 different output signals including active high, active low, positive pulse, and negative pulse. The versatility of the RTL8139C(L)+ LWAKE pin provides motherboards with the Wake-On-LAN (WOL) function.
