1.0 Introduction
The Intel® 82540EP Gigabit Ethernet Controller is a single, compact componen t 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 very small area that is footprint compatible with
current generation 10/100 Mbps Fast Ethernet designs
The Intel® 82540EP integrates Intel’s fourth gene r a tion gigabit MAC design with fully integ r ated,
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) 2.2 compliant interface 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 operation. These features optimize m o bil e applicatio ns.
The Intel® 82540EPs on-board System Management Bus (SMB) port enables network
manageability implementations required by information technology personnel fo r remote control
and alerting via the LAN. With SMB, manag ement packets can be rou ted to or fr om a managem ent
processor. The SMB port enables industry standar ds, such as Intelligent Platform Management
Interface (IPMI) and Alert Standard Forum (ASF), to be implemented using the 82540EP. In
addition, on chip ASF 1.0 cir cuitry pro vides alerting and remote control capabilities with
standardized interfaces.
The 82540EP Gigabit Ethernet Controll er architect ure is designed to deliver high per for mance and
PCI bus efficiency. Wide internal data paths eliminate performance bottleneck s by eff icien tly
handling large address and data words. The 82540EP 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 packet descriptors in a single burst for efficient
PCI bandwidth use. A large 64 KByte on-chip packet buffer maintains superior performance 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 82540EP is packaged in a 15 mm2 196-ball grid array and is pin compatible with both the
82551QM 10/100 Mbps Fast Ethernet Multifunctio n PCI/CardBus Controller and the 82540EM
Gigabit Ethernet Controller (which does not have added power saving features like CLK_RUN#).

3.0 Signal Descriptions
Note: The targeted signal names are subject to change withou t notice. Verify with your local Intel sales
office that you have the latest inform ation before finalizing a design.
3.1 Signal Type Definitions
The signals of the 82540EP controller are electrically defined as follows:
3.2 PCI Bus Interface
When the Reset signal (RST#) is asserted, the 82540EP will not drive any PCI output or bi-
directional pins except the Power Management Event signal (PME#).
3.2.1 PCI Address, Data and Control Signals
Name Definition
IInput. Standard input only digital signal.
OOutput. Standard output only digital s ignal.
TS Tri-state. Bi-directional three-state digital input/output signal.
STS
Sustained Tri-state. Sustained digital three-state signal driven by one agent at a time.
An agent driving the STS pin low must actively drive it high for at least one clock before letting it
float. The next agent of the signal cannot drive the pin earlier than one clock after it has been
released by the previous agent.
OD
Open Drain. Wired-OR with other agents.
The signaling agent asserts the OD signal, but the signal is returned to the inactive state by a
weak pull-up resistor. The pull-up resi stor 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.
Symbol Type Name and Function
AD[31:0] TS
Address and Data. Address and dat a 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
82540EP 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).
82540EP — Networking Silicon
8
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 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. T he 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 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 82540EP 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 C ycle Frame. The Fra me sig na l i s dr iven by the 82540EP device to indicate the
beginning and length of an access and indicate the beginning 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 82540E P controller (as 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 82540EP 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 82540EP controller
(as a selected device) to complete the current dat a 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. The 82540EP 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 82540EP controller drives STOP# to request the
bus master to stop the transaction. As a master, the 82540EP controller receives
STOP# from the slave to stop the current transaction.
IDSEL# I Initia lization Device Select. The Initialization Device Select signal is used by the
82540EP 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 82540EP, it
signals notifies the bus master that it has decoded its addres s 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 VI O 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: An external resistor is required between the voltage reference and the VIO pin.
The target resistor value is 100 K

3.2.2 Arbitration Signals
3.2.3 Interrupt Signal
3.2.4 System Signals
3.2.5 Error Reporting Signals
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 Grant Bus signal notifies the 82540EP that bus access has been
granted. This is a point-to-point signal.
LOCK# I Lock Bus. The Lock Bus signal is asserted by an initiator to require sole access to a
target memory device during two or more separate transfers. The 82540EP device
does not implement bus locking.
Symbol Type Name and Function
INTA# TS Interrupt A. Interrupt A is used to request an interrupt by port 1 of the 82540EP. 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 82540EP 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 66 MHz.
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 82540EP is reset on the de-assertion (rising edge) of
RST#.
CLK_RUN# I/O
OD
Clock Run. This signal is used by the system to pause the PCI clock signal. It is used
by the 82540EP controller to request the PCI clock. When the CLK_RUN# feature is
disabled, leave this pin unconnected.
Symbol Type Name and Function
SERR# OD System Error. The System Er ror signal is used by the 82540EP controller to report
address parity errors. SERR# is open drain and is actively driven for a single PCI clock
when reporting the error.
PERR# STS
Parity Error. The Parity Error signal is used by the 82540EP controller to report data
parity errors during all PCI transactions except by a Special Cycle. PERR# is sustained
tri-state and must be driven active by the 82540EP controller two data c locks after a
data parity error is detected. The minimum duration of PERR# is one clock for each
data phase a data parity error is present.

5.3 Thermal S pecifications
The 82540EP device is specified for operation when the ambient temperature (TA) is within the
range of -40° C to 85° C.
TC (case temperature) is calculated using the equation:
TC = TA + P (θJA - q JC)
TJ (junction temperature) is calculated using the equation:
TJ = TA + P θJA
P (pow er consumption) is c alcula t ed by using the typical ICC, as indicated in Table 4 of Section
4.0, and nominal VCC. The thermal resistances are shown in Table 18.
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 82540EP device is operating under recommended conditions.
