This product is covered by one or more of the following patents:
US5,307,459, US5,434,872, US5,732,094, US6,570,884, US6,115,776, and US6,327,625.

The Realtek RTL8139C(L) is a highly integrated and cost-effective single-chip Fast Ethernet controller. It is enhanced with an ACPI (Advanced Configuration Power Interface) management function for PCI/Mini-PCI/Cardbus in order to provide efficient power management for advanced operating systems with OSPM (Operating System Directed Power Management). The RTL8139C(L) also provides a remote wake-up function by Magic Packet & Wake-up Frame to increase cost-efficiency in network maintenance and management. Furthermore, it supports the Cardbus interface for PC Card applications and is an ideal solution for notebook/motherboard-embedded network design.
