Single-Chip 10/100M Fast Ethernet Controller Integrated with MC'97 Controller
General Description

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 RTL8101L is a highly integrated and cost-effective single-chip Fast Ethernet controller. Featuring an MC'97 interface, the device is able to provide a combo-solution for LAN and software modem applications. The RTL8101L is equipped with a PCI and Boot ROM share interface (Realtek patent pending) for both EPROM and Flash Memory to provide maximum network security and ease of management.

The RTL8101L offers an ACPI (Advanced Configuration Power Interface) management function to provide efficient power management for advanced operating systems with OSPM (Operating System Directed Power Management). A remote wake-up function is also provided by support to Magic Packet, Link Change, and Wake-up Frame to increase cost-efficiency in network maintenance and management. In addition, the RTL8101L supports analog Auto Power-down and provides an auxiliary power auto-detect function to further save power.
