描述 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 RTL8139C(L)+ is a highly integrated and cost-effective single-chip Fast Ethernet controller. It provides enhanced buffer management with descriptor-based TX/RX architecture to greatly reduce CPU utilization. Fully complying with Microsoft NDIS5 Checksum and Segmentation Task-offload feature, the RTL8139C(L)+ is able to optimize system performance. Also supporting IEEE802.1Q VLAN (Virtual Bridged Local Area Network) and PCI DAC (Dual Address Cycle), the new chip provides an optimum LAN solution for high-end and heavy-trafficked computers and network servers.
The RTL8139C(L)+ provides optional Boot ROM and MII interfaces, respectively for diskless workstations and extra applications such as Phyceiver and fiber connections. The chip is equipped with an ACPI (Advanced Configuration Power Interface) management function 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. It supports the Cardbus interface for PC Card applications and is also an ideal solution for notebook/motherboard-embedded network design as well as for NIC card design.
