networking silicon ? 82540EP 1 1.0 introduction the intel ? 82540EP gigabit ethernet controller is a si ngle, compact component with an integrated gigabit ethernet media access control (mac) and physical layer (phy) functions. for desktop, workstation and mobile pc network designs with critical space constraints, the intel ? 82540EP allows for a gigabit ethernet implementation in a ve ry small area that is f ootprint compatible with current generation 10/100 mbps fast ethernet designs the intel ? 82540EP integrates intel?s fourth generation gigabit mac design with fully integrated, physical layer circuitry to provide a standard ieee 802.3 ethernet interface for 1000base-t, 100base-tx, and 10base-t applications (802.3, 802 .3u, and 802.3ab). the controller is capable of transmitting and receiving data at rates of 1000 mbps, 100 mbps , or 10 mbps. in addition to managing mac and phy layer functions, the controller provides a 32-bit wide direct peripheral component interconnect (pci) 2.2 compliant in terface capable of operating at 33 or 66 mhz. the 82540EP also incorporates the clk_run# protocol and hardware supported downshift capability to two or three-pair 100 mb/s operat ion. these features optim ize mobile applications. the intel ? 82540EP?s on-board system management bus (smb) port enables network manageability implementations required by inform ation technology personnel for remote control and alerting via the lan. with smb, management packets can be routed to or from a management processor. the smb port enables industry standa rds, such as intelligent platform management interface (ipmi) and alert standa rd forum (asf), to be implem ented using the 82540EP. in addition, on chip asf 1.0 circuitry provides alerting and remote control capabilities with standardized interfaces. the 82540EP gigabit ethernet controller architect ure is designed to deliver high performance and pci bus efficiency. wide internal data paths eliminate performance bot tlenecks by efficiently handling large address and data words. the 8254 0ep controller includes advanced interrupt handling features to limit pci bus traffic and a pci interface that maximizes the use of bursts for efficient bus usage. the 82540EP caches up to 64 pack et descriptors in a single burst for efficient pci bandwidth use. a large 64 kbyte on-chip pack et buffer maintains superior performance as available pci bandwidth changes. in addition, us ing hardware acceleration, the controller offloads tasks from the host controller, such as tcp/ udp/ip checksum calculations and tcp segmentation. the 82540EP is pack aged in a 15 mm 2 196-ball grid array and is pin compatible with both the 82551qm 10/100 mbps fast ethernet multifunction pci/cardbus controller and the 82540em gigabit ethernet controller (which does not have added power saving features like clk_run#). 1.1 document scope this document contains datasheet specifications for the 82540EP gigabit ethernet controller, including signal descriptions, dc and ac parameters, packaging data, and pinout information.
