networking silicon ? 82541(pi/gi/ei) 7 1.0 introduction the intel ? 82541(pi/gi/ei) gigabit ethernet is a single, 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 ? 82541(pi/ gi/ei) allows for a gigabit ethernet implementa tion in a very small area that is footprint compatible with current generation 10/100 mbps fast ethernet designs. the intel ? 82541(pi/gi/ei) integrates 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) 2.3 compliant inte rface capable of operating at 33 or 66 mhz. the 82541(pi/gi/ei) also incorporates the clock run protocol and hardware supported downshift capability to two-pair and three-pair 100 mbps operation. these features optimize mobile applications. the 82541(pi/gi/ei) on-board system management bus (smb) port enables network manageability implementations required by information technology personnel for remote control and alerting via the local area network (lan). with smb, management packets can be routed to or from a management processor. the smb port enables industry standards, such as intelligent platform management interface (ipmi) and alert standard forum (asf) 2.0, to be implemented using the 82541(pi/gi/ei). in addition, on chip asf 2.0 circuitry provides alerting and remote control capabilities with standardized interfaces. the 82541(pi/gi/ei) gigabit ethernet controller architecture is designed for high performance and low memory latency. wide internal data path s eliminate performance bo ttlenecks by efficiently handling large address and data words. the 82541(p i/gi/ei) controller includ es advanced interrupt handling features to limit pci bus traffic and a pc i interface that maximizes efficient bus usage. the 82541(pi/gi/ei) uses efficient ring buffer desc riptor data structures, with up to 64 packet descriptors cached on chip. a large 64-kbyte onchip packet buffer maintains superior performance as available pci bandwidth changes. in addition, using hardware acceleration, the controller offloads tasks from the host controller, su ch as tcp/udp/ip checksum calculations and tcp segmentation. the 82541(pi/gi/ei) is packaged in a 15 mm x 15 mm 196-ball grid array and is pin compatible with the 82551qm 10/100 mbps fast ethernet multifunction pci/cardbus controller, 82562ez(ex) platform lan connect devices, and the 82540ep(em) gigabit ethernet controller. 1.1 document scope the 82541ei is the original device and is now being manufactured in a b0 stepping. the 82541gi (b1 stepping) and 82541pi (c0 stepping) are pin compatible, however, a different intel software driver is required from the 82541ei. this doc ument contains datasheet specifications for the 82541(pi/gi/ei) gigabit ethernet controllers including signal descriptions, dc and ac parameters, packaging data, and pinout information.

82541(pi/gi/ei) ? networking silicon 12 3.2.1 pci address, data and control signals (44) symbol type name and function ad[31:0] ts address and data. address and data signals are multiplexed on the same pci pins. a bus transaction includes an address phase followed by one or more data phases. the address phase is the clock cycle when the frame signal (frame#) is asserted low. during the address phase ad[31:0] contain a physical address (32 bits). for i/o, this is a byte address, and for configuration and memory, a dword address. the 82541(pi/gi/ei) device uses little endian byte ordering. during data phases, ad[7:0] contain the least significant byte (lsb) and ad[31:24] contain the most significant byte (msb). c/be#[3:0] ts bus command and byte enables. bus command and byte enable signals are multiplexed on the same pci pins. during the address phase of a transaction, c/ be#[3:0] define the bus command. in the data phase, c/be#[3:0] are used as byte enables. the byte enables are valid for the entire data phase and determine which byte lanes contain meaningful data. c/be[0]# applies to byte 0 (lsb) and c/be#[3] applies to byte 3 (msb). par ts parity. the parity signal is issued to implement even parity across ad[31:0] and c/ be#[3:0]. par is stable and valid one clock after the address phase. during data phases, par is stable and valid one clock a fter either irdy# is asserted on a write transaction or trdy# is asserted after a read tr ansaction. once par is valid, it remains valid until one clock after the completion of the current data phase. when the 82541(pi/gi/ei) controller is a bus master, it drives par for address and write data phases, and as a slave device, drives par for read data phases. frame# sts cycle frame. the frame signal is driven by the 82541(pi/gi/ei) device to indicate the beginning and length of a bus transaction. while frame# is asserted, data transfers continue. frame# is de-asserted when the transaction is in the final data phas e. irdy# sts initiator ready. initiator ready indicates the abilit y of the 82541(pi/gi/ei) controller (as a bus master device) to complete the current data phase of the transaction. irdy# is used in conjunction with the target ready signal (trdy#). the data phase is completed on any clock when both irdy# and trdy# are asserted. during the write cycle, irdy# indicates that valid data is present on ad[31:0]. for a read cycle, it indicates the master is ready to accept data. wait cycles are inserted until both irdy# and trdy# are asserted toget her. the 82541(pi/gi/ei) controller drives irdy# when acting as a master and samples it when acting as a slave. trdy# sts target ready. the target ready signal indicates the ability of the 82541(pi/gi/ei) controller (as a selected device) to complete the current data phase of the transaction. trdy# is used in conjunction with the initiator ready signal (irdy#). a data phase is completed on any clock when both trdy# and irdy# are sampled asserted. during a read cycle, trdy# indicates that valid data is present on ad[31:0]. for a write cycle, it indicates the target is ready to accept data. wait cycles are inserted until both irdy# and trdy# are asserted together. t he 82541(pi/gi/ei) device drives trdy# when acting as a slave and samples it when acting as a master. stop# sts stop. the stop signal indicates the current target is requesting the master to stop the current transaction. as a slave, the 82541(pi /gi/ei) controller drives stop# to request the bus master to stop the transaction. as a master, the 82541(pi/gi/ei) controller receives stop# from the slave to stop the current transaction.
