Networking Silicon — 82541(PI/GI/EI)

1.0 Introduction

The Intel® 82541(P I/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 Ethern et implementat ion 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 10BA SE-T applicatio ns (802.3, 8 02.3u, and 802.3ab). Th e controlle r 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 interface 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 featu res optimize m obile

applications.

The 82541(PI/GI/EI) on-board System Management Bus (SMB) port enables network

manageability implementations required by information technology personnel fo r remote control

and alerting via the Local Area Network ( LAN). With SMB, manage ment p ackets can be routed to

or from a management processor. The SMB por t enables in dustry standards, such as Intelligent

Platform Management Interface (IPMI) and Alert Standard Forum (AS F) 2.0, to be implemented

using the 82541(PI/GI/EI) . In additio n, o n chip A SF 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 paths eliminate perfor mance bottlenecks by ef ficiently

handling l arge add ress and data wor ds. The 82541(PI /GI/EI) controller includes advanced interrupt

handling features to limit PCI bus traffic and a PCI interface that maximizes efficient bus usage.

The 82541(PI/GI/EI) uses efficient ring buffer descriptor data s tructures, with up to 64 packet

descriptors cached on chip. A lar ge 64-KByte on chip packet buffer maintains superior perf ormance

as available PCI bandwidth changes. In addition, using hardware acceleration, the controller

offloads tasks from the host controller, such 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/Card Bus 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 so ftware

driver is required from the 82541EI. This document contains datasheet specifications for the

82541(PI/GI/EI) Gigabit Ethernet Controllers in cluding signal descriptions, DC and AC

parameters, packaging data, and pinout information.

2.0 Architectural Overview

2.1 External Architecture Block Diagram

The 82541(PI/GI/EI) architect ure is a derivative of the 82542, 82543, and 82544 designs that

provided Media Access Controller (MAC) functionality as well as an integrated 10/100/1000Mbps

copper PHY. The 82541(PI/GI/EI) family architecture now adds SMBus-based manageability and

an integrated ASF contro ller functionality to the MAC.

2.2 Internal MAC Architecture Block Diagr am

Figure 2 shows the major internal function blocks of 82541(PI/GI/EI) MAC device. Compared to

its predecessors, the 82541(PI/GI/EI) MAC adds improv ed receive-packet filtering to support

SMBus-based manageability, as well as the ability to supp ort tr ansmit of SMBus-based

manageability packets. In addition, an ASF-compliant TCO controller is integrated into the MAC

for reduced-cost basic ASF manageability.

Figure 2. Internal Architecture Block Diagram

2.3 Integrated 10/100/1000Mbps PHY

The 82541(PI/GI/EI) cont ains an integrated 10/100/1000Mbps-capable Copper PHY. This PHY

communicates with the MAC controller using a standard GMII/MII interface internal to the

component to transfer transmit and receive data. A standard MDIO interface, accessible to

software via MAC control registers, is used to configure and monitor the PHY operation.

2.4 System Interface

82541(PI/GI/EI) provides a 32-bit PCI 2.2 bus interface which is capable of up to 66 MHz

operation in conventional PCI mode. In conventional PCI systems with a dedicated I/O bus per

connector, this interface should provide sufficient bandwidth to support a sustained 1000 Mb/sec

transfer rate. 64 KB of on-chip buffering mitigates instantaneous receive bandwidth demands and

eliminates transmit under-runs by buffering the entire outgoing packet prior to transmis sion.

3.0 Signal Descriptions

3.1 Signal Type Definitions

The signals of the 82541(PI/GI/EI) controller are electrically defined as fo llows:

3.2 PCI Bus Interface Signals (56)

When the Reset signal (RST#) is asserted, the 82541(PI/GI/EI) will not drive any PCI output or bi-

directional pins. The Power Management Event signal (PME#) can be active by configuri ng

manageability func tions.

Name Definition

IInput. Standard input only digital signal.

OOutput. Standard output only digital signal.

TS Tri-state. Bi-directional tri-state digital input/output signal.

STS

Sustained Tri-state. An active low tri-state signal owned and dr iven by only one agent at a

time. The agent that drives an STS pin low must drive it high for at least one clock before letting

it float. A new agent cannot start driving an STS signal any sooner than one clock after the

previous owner tri-states it. A pull-up resistor is required to sustain the inactive state until

another agent drives it, and must be provided by the central resource.

Open Drain. Wired-OR with other agents.

The signaling agent asserts the OD signal, but the signal is retu r ned to the inactive state by a

weak pull-up resistor. The pull-up resistor may require two or three clock periods to fully restore

the signal to the de-asserted state.

AAnalog. PHY analog data signal.

PPower. Power connection, voltage reference, or other reference connection.

82541(PI/GI/EI) — Networking Silicon

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 le ast 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 t ransac tion, 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 ent ire dat a 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 v alid one clock after the address phase. During data

phases, PAR is stable and valid one clock after either IRDY# is asserted on a write

transaction or TRDY# is asserted aft er a read transaction. Once P AR 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 Fram e s i gnal is driven by t h e 82541(P I/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 phase.

IRDY# STS

Initiator Ready. Initiator Ready indicates the ability 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. W ait cycles are inserted until

both IRDY# and TRDY# are asserted together. The 82541(PI/GI/EI) cont roller 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 Initiat or 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. The 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.

Networking Silicon — 82541(PI/GI/EI)

3.2.2 Arbitration Signals (2)

3.2.3 Interrupt Signal (1)

3.2.4 System Signals (4)

IDSEL I Initialization Device Select. The Initialization Device Select signal is used by the

82541(PI/GI/EI) as a chip select signal during configuration read and write transactions.

DEVSEL# STS

Device Select. When the Device Select signal is actively driven by the 82541(PI/GI/

EI), it signals the bus master that it has decoded its address as the target of the current

access. As an input, DEVSEL# indicates whether any device on the bus has been

selected.

VIO P

VIO. The VIO signal is a voltage reference for the PCI interface (3.3 V or 5 V PCI

signaling environment). It is used as the clamping voltage.

Note: VIO should be connected to 3.3 V Aux or 5 V Aux in order to be compatible with

the pull-up clamps specification.

Symbol Type Name and Function

REQ# TS Request Bus. The Request Bus signal is used to request control of the bus from the

arbiter. This signal is point-to-point.

GNT# I Grant Bus. The Gr ant Bus signal notifies the 82541(PI/GI/EI) that bus access has

been granted. This is a point-to-point signal.

Symbol Type Name and Function

INTA# TS Interrupt A. Interrupt A is used to request an interrupt of the 82541(PI/GI/EI). It is an

active low, level-triggered interrupt signal.

Symbol Type Name and Function

CLK I

PCI Clock. The PCI Clock signal provides timing for all transactions on the PCI bus

and is an input to the 82541(PI/GI/EI) device. All other PCI signals, except the Interrupt

A (INTA#) and PCI Reset signal (RST#), are sampled on the rising edge of CLK. All

other timing parameters are defined with respect to this edge.

M66EN I 66 MHz Enable. M66EN indicates whether the system bus is enabled for 66MHz.

RST# I

PCI Reset. When the PCI Reset signal is asserted, all PCI output signals, except the

Power Management Event signal (PME#), are floated and all input signals are ignored.

The PME# context is preserved, depending on power management settings.

Most of the internal state of the 82541(PI/GI/EI) is reset on the de-assertion (rising

edge) of RST#.

CLK_RUN# I/O

Clock Run. This signal is used by the system to pause the PCI clock signal. It is used

by the 82541(PI/GI/EI) controller to request the PCI clock. When the CLK_RUN#

feature is disabled, leave this pin unc onnect ed.

PWR_GOOD IPower Good (Power -on Reset). The LAN_PWR_GOOD signal is used to indicate

that stable power is available f or the 82541(PI/GI/EI). Whe n the signal is low, the

82541(PI/GI/EI) holds itself in res e t state and floats all PCI signals.

PME# OD

Power Manage m ent Event. The 82541(PI/GI/EI) device drives this signal low when

it receives a wake-up event and either the PME Enable bit i n the Power Management

Control/Status Register or the Advanced Power Management Enable (APME ) bit of

the Wake-up Control Register (WUC) is 1b.

AUX_PWR I Auxiliary Power. If the Auxiliary Power signal is high, then auxiliary power is

available and the 82541(PI/GI/EI) device should support the D3cold power state.

5.2 Thermal S pecifica tions

The 82541(PI/ GI/EI) device is specified for operation when the ambien t temperature ( TA) is within

the range of 0° C to 70° C.

TC (case temperature) is calculated using the equation:

TC = TA + P (θJA - θJC)

TJ (junction temperature) is calculated using the equation:

TJ = TA + P θJA

P (power co nsumption) i s calculated by usin g the typical I CC, as ind icated in Table 7 of Section 4.0,

and nominal VCC. The preliminary thermal resistances are shown in Table 13.

Thermal resistances are determined empirically with test devices mounted on standard thermal test

boards. R eal system designs may hav e dif ferent character istics due to board thickness, arr angement

of ground planes, and proximity of other components. The case temperature measurements should

be used to assure that the 82541(PI/GI/EI) device is operating under recommended conditions.
