A fully integrated 10/100/1000BASE-T Dual-Port Gigabit Ethernet controller for high-performance server applications
The BCM5715C is a fourth-generation 10/100/1000BASE-T dual-port LAN controller for high-performance server applications. The device combines dual triple-speed IEEE 802.3-compliant Media Access Controllers (MACs) with dual 10/100/1000 Ethernet Transceivers, a Universal Management Port (UMP) and an on-chip memory buffer in a single device. The device is fabricated in a 1.2V CMOS process, providing a low-power system solution. 
  The BCM5715C provides a single x4 PCI Express® host interface and two Gigabit Ethernet Controllers. Each function has its own PCI configuration space. Each Ethernet controller has a dedicated on-chip high-performance RISC processor for custom frame features.
