The Broadcom® BCM5721 is one of three NetXtreme™ Gigabit Ethernet (GbE) controllers that implement the advanced PCI Express host interface. Representing the world's first support for the PCI Express specification, the BCM5721 combines innovative performance enhancements with a PCI Express 1x host interface enabling 2 Gbps throughput for the most demanding server applications. To reduce the total cost of server ownership, the BCM5721 supports the Intelligent Platform Management Interface (IPMI) 1.5 manageability standard that allows servers to be remotely managed. The BCM5721 also incorporates the industry's most advanced server software (the Broadcom Advanced Server Program or BASP) which offers several innovative teaming functions not available from any other GbE controller solution.

Built upon six generations of field-proven Gigabit Ethernet media access controller (MAC) and physical layer (PHY) transceiver technology, the BCM5721 utilizes a fully integrated 10/100/1000BASE-T Gigabit Ethernet MAC, PCI Express bus interface, on-chip buffer memory, and integrated PHY in a single-chip solution designed specifically for LAN on motherboard (LOM) and network interface card (NIC) applications. This single chip solution is fabricated in a low-voltage, 0.13-micron CMOS process that provides low power consumption.

The BCM5721 features a comprehensive software suite offering a complete solution for client and server applications, including drivers for all popular operating systems. The NetXtreme architecture also features a unique processor-based design, enabling advanced management software to run in firmware so it can be remotely upgraded via simple downloads.
