Placa de rede PCI 10/100M é um Adaptador Fast Ethernet altamente integrado e de baixo custo que oferece desempenho de 32 bits, um controlador PCI bus, e em total conformidade com o padrão IEEE 802.3 10Base-T, especificações IEEE 802.3u 100Base-TX e Controle de Fluxo Full Duplex IEEE 802.3x. Placa com Chipset Realtek 8139D mantém baixo custo e elimina as barreiras de uso. É fácil de aumentar uma rede de 10 Mbps para 100 Mbps. Suporta velocidade de rede de 10Mbps e 100Mbps, tanto em modos de transferência Half-Duplex como Full-Duplex, usando a tecnologia de Auto Negociação para detectar a velocidade da rede. Ele também pode ser amplamente utilizado em sistemas operacionais mais modernos.
Single-Chip 10/100M Fast Ethernet Controller with Power Management and Multi-Function
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 RTL8139D(L) is a highly integrated and cost-effective single-chip Fast Ethernet controller. Providing a highly flexible multi-function mode (Realtek patent pending), the new chip is able to support a versatile combination of applications. Furthermore, the RTL8139D(L) 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 RTL8139D(L) 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 RTL8139D(L) supports analog Auto Power-down and provides an auxiliary power auto-detect function to further save power.
