These devices use PCIe* architecture (Revision 1.0a). For desktop, workstation, and value server network designs with critical space constraints, the 82573 enables a GbE implementation in a very small area. The 82573 provides a standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX, and 10BASE-T applications (802.3, 802.3u, and 802.3ab, respectively). In addition to managing MAC and PHY Ethernet layer functions, the 82573 manages PCIe* packet traffic across its transaction, link, and physical and logical layers. The 82573E contains a dedicated microcontroller for manageability with an on-board Intel® Active Management Technology (Intel® AMT) enabling network. This enables manageability implementations required by information technology personnel for outof-band management, remote troubleshooting and recovery, asset management, and non-volatile storage. Intel® AMT is the first step towards a complete Intel® CrossPlatform Manageability Program (Intel® CPMP), which is a business and technology initiative to deliver consistent management capabilities, protocols, and interfaces across all Intel platforms. The 82573E and 82573V GbE controllers have an integrated System Management Bus (SMBus) port enabling industry standards, such as the Alert Standard Forum (ASF) 2.0. With SMBus, management packets can be routed to or from a management processor. In addition, integrated ASF 2.0 circuitry provides alerting and capabilities with standardized interfaces. The 82573 with PCIe* architecture is designed for high performance and low memory latency. The device is optimized to connect to a system I/O Control Hub (ICH7) using one PCIe* lane. Alternatively, the 82573 is able to connect to a Memory Control Hub (MCH) device with a PCIe* interface. Wide internal data paths eliminate performance bottlenecks by efficiently handling large address and data words. The 82573 efficiently handles packets with minimum latency by combining a parallel and pipelined logic architecture optimized for GbE and independent transmit and receive queues. The 82573 also includes advanced interrupt handling features and uses efficient ring buffer descriptor data structures, with up to 64 packet descriptors per queue cached on chip. A 32-KB on-chip packet buffer maintains superior performance. In addition, using hardware acceleration, the 82573 offloads tasks from the host (for example, TCP/UDP/IP checksum calculations and TCP segmentation). The 82573L features low power management. During the L1 and L2 link states, the 82573L asserts the Clock Request signal (CLKREQ#) to indicate that its PCIe* reference clock can be gated. The 82573 is packaged in a 15 mm X 15 mm, 196-Ball Grid Array (BGA). 7 82573—Datasheet 1.1 Document Scope This document contains targeted datasheet specifications for the 82573 GbE controller, including signal descriptions, DC and AC parameters, packaging data, and pinout information. 1.2 Reference Documents This application assumes that the designer is acquainted with high-speed design and board layout techniques.

O Output Standard output only digital signal. I/O I/O Standard I/O digital signal. TS Tri-state Bi-directional three-state digital input/output signal. OD Open Drain Wired-OR with other agents. The signaling agent asserts the open drain signal, but the signal is returned to the inactive state by a weak pull-up resistor. The pull-up resistor might require two or three clock periods to fully restore the signal to the de-asserted state. A Analog PCIe, SerDes, or PHY analog signal. P Power Power connection, voltage reference, or other reference connection. Datasheet—82573 Name 2.2 Definition B Input Bias PU Pull Up This signal requires a pull-up resistor. PD Pull Down This signal requires a pull-down resistor. PCIe* Data Signals Signal 2.3 Type Name and Function PE_CLKn PE_CLKp A(In) PCIe Differential Reference Clock The reference clock is furnished by the system and has a 300 ppm frequency tolerance. It is used as reference clock for PCIe transmit and receive circuitry and is used by the PCIe core PLL to generate 125 MHz and 250 MHz clocks for the PCIe* core logic. PE_T0n PE_T0p A(0ut) PCIe* Serial Data Output These signals connect to corresponding PERn and PERp signals on a system motherboard or a PCIe* connector. Series AC coupling capacitors are required at the 82573 device end. The PCIe* differential outputs are clocked at 2.5 Gb/s. PE_R0n PE_R0p A(In) PCIe Serial Data Input These signals connect to corresponding PETn and PETp signals on a system motherboard or a PCIe* connector. The PCIe* differential inputs are clocked at 2.5 Gb/s. PCIe* Miscellaneous Signals Signal Type Name and Function I Reset This signal indicates whether or not the PCIe* power and clock are available. PE_WAKE# OD Wake This signal is driven to zero when it receives a wake-up packet and either the PME enable bit of the Power Management Control/Status Register is set to 1b or the Advanced Power Management enabled bit of the Wake Up Control Register equals 1b. AUX_ PRESENT (AUX_PWR)1 I Auxiliary Power Present AUX_PRESENT must be pulled up to 3.3V standby power if the 82573 is powered from standby supplies. This signal must be pulled down if auxiliary power is not used. OD Clock Request. The Clock Request (CLKREQ#) signal is located at ball P9 of the 82573L. When it is sampled high, this open-drain signal alerts the system that the 82573L does not need the PCIe* differential reference clock. During normal operation, the 82573L keeps CLKREQ# asserted (low), and the system supplies this clock to the device on the PE_CLKp and PE_CLKn signals. The 82573L deasserts CLKREQ# (high) when it is in an electrical idle state (L1 and L2), and the system might choose to continue supplying the reference clock or gate it conserving platform power. The CLKREQ# signal should be connected to the clock driver that supplies the 82573L PCIe* clock. If other devices use the same CLKREQ# signal, a pull-up resistor should be used to ensure that no device pulls this signal low when it is powered off. PE_RST# CLKREQ# (82573L only) 1. This signal is used in all three devices and has the same functionality but is denoted as AUX_PRESENT in the 82573E/V and AUX_PWR in the 82573L. 11 82573—Datasheet 2.4 Non-Volatile Memory Interface Signals Signal Type Name and Function NVM_SI I/O NVM Serial Data Output The data output pin is used for input to the non-volatile memory device.

NVM_SK O TS NVM Serial Clock The serial clock provides the clock rate for the memory interface. NVM_CS# I/O NVM Chip Enable This signal is used to enable the device. This signal has an internal pull-up resistor. NVM_REQ O NVM Arbitration Request. This signal is used to request use of the NVM interface. NVM_PROT I/PU NVM Protection Enable. This pin should be connected to ground to disable NVM protection; otherwise, NVM protection is enabled. This signal has an internal pull-up resistor. NVM_TYPE I/PU NVM Device Type If the device uses a Flash, this pin should be connected to a pull-down resistor. If the 82573 is connected to an EEPROM, this pin can be connected to an external pull-up resistor. This signal has an internal pull-up resistor of 30 KΩ ±50%. NVM_SHARED# I/PU NVM Shared Enable This pin should be connected to a pull-down resistor to enable sharing of SPI Flash with ICH. This signal has an internal pull-up resistor. 2.5 Miscellaneous Signals 2.5.1 Reset and Power-down Signals Signal 12 Type Name and Function LAN_PWR_ GOOD I LAN Power Good This signal indicates that stable power is available to the 82573. When the signal is low, LAN_PWR_GOOD acts as a master reset of the entire device. LAN_PWR_GOOD should be connected to a power supervisor driven from auxiliary power. The signal should go active approximately 80 ms after all power rails are within their operating ranges. A PCIe* reset must only occur after LAN Power Good is active. DEVICE_OFF# I Device Off This asynchronously disables the 82573, including voltage regulator control outputs if selected in external control.

This is covered in Section 3.3.1. • Powering the 82573 with only an external 3.3V supply and using internal power regulators from the 82573 combined with external PNP transistors to supply the 2.5V and 1.2V levels. This is covered in Section 3.3.3. • Using the 2.5V internal (on-die) regulator combined with an external PNP transistor to supply the 1.2V level. This is covered in Section 3.3.3. 17 82573—Datasheet 3.3.1 External LVR Power Delivery The following power supply requirements apply to designs where the 82573 is supplied by external voltage regulators. These systems do not use the internal regulator logic built into the 82573 as described in Section 3.3.3.

Tantalum capacitors must not be used. 3.3.2 Power Sequencing with External Regulators The following power-on and power-off sequence should be applied when external power supplies are in use. Designs must comply with the required power sequence to avoid risk of either latch-up or forward biased internal diodes. Generally, the 82573 power sequencing should power up the three power rails in the following order: 3.3V Æ 2.5V Æ 1.2V. However, if this general guideline is not followed, there are specific requirements that must be adhered to. These requirements are listed in the following two subsections. 3.3.2.1 External LVR Power Up Sequencing and Tracking Sequencing of the external supplies during power up might be necessary to ensure that the 82573 is not electrically overstressed and does not latch-up. These requirements are shown in Figure 2. The 82573 core voltage (1.2V) cannot exceed the 3.3V supply by more than 0.5 V at any time during the power up. The 82573 core voltage (1.2V) cannot exceed the 2.5V supply by more than 0.5 V at any time during the power up. The core voltage is not required to begin ramping before the 3.3V or the 2.5V supply. The 82573 analog voltage (2.5V) can not exceed the 3.3V supply by more than 0.5 V at any time during the power up. The analog voltage is not required to begin ramping before the 3.3V supply. 19 82573—Datasheet Figure 2. Minimum Requirements for Power Supply Sequencing Max Difference ≤ 0.3 V 3.3V 3.3V 2.5V 2.5V Max Difference ≤ 0.3 V 1.2V (Core Supply) 1.2V (Core Supply) Max Difference ≤ 0.3 V Max Difference ≤ 0.3 V • If the 1.2V and 2.5V rails power up before 3.3V, they should never exceed the 3.3V supply by more than 0.3 V. • At power down, all three supplies should be turned off simultaneously. If the 3.3V supply powers down first, the 1.2V and 2.5V supplies must never exceed the 3.3V supply by more than 0.3 V. 3.3.2.2 External LVR Power Down Sequencing There are no specific power down sequencing and tracking requirements for the 82573 silicon. The risk of latch-up or electrical overstress is small since the only charge storing in decoupling capacitors is left in the system. 3.3.3 Internally Generated Power Delivery The 82573 has two internal linear voltage regulator controllers. The controllers use external transistors to generate 2 of the 3 required voltages: 2.5V (nominal) and 1.2V (nominal). These two voltages are stepped down from a 3.3V source. Table 6. 3.3V Internal Power Supply Parameters Parameter Description Min Max Units Rise Time Time from 10% to 90% mark 5 Monotonicity Voltage dip allowed in ramp - 300 mV ms Slope Ramp rate at any given time between 10% and 90% Min: 0.8*V(min)/Rise time (max) Max: 0.8*V(max)/Rise time (min) - 1500 mV/ms Operational Range Voltage range for normal operating conditions 3.0 3.6 V Ripple1 Maximum voltage ripple (peak to peak) - 100 mV Overshoot Maximum overshoot allowed - 660 mV Overshoot Settling Time Maximum overshoot allowed duration. (At that time delta voltage should be lower than 5 mV from steady state voltage) - 3 ms 1. The peak to peak output rippled is measured at 20 MHz bandwidth within the operational range. 20 Datasheet—82573 3.3.4 Internal LVR Power Sequencing All supplies should rise monotonically. Sequencing of the supplies is controlled by the 82573. 3.3.4.1 Power Up Sequencing and Tracking During power up, the sequencing and tracking of the internally controlled supplies (2.5V and 1.2V) are controlled by the 82573. No specific motherboard requirements are necessary to prevent electrical overstress or latch-up. The 82573 analog voltage (2.5V) never exceeds the 3.3V supply at any time during the power up. This is because the 2.5V supply is generated from the 3.3V supply when the internal voltage regulator control logic is being used. Figure 3 shows the internal LVR circuit. The 2.5V supply tracks the 3.3V ramp. The 82573 core voltage (1.2V) never exceeds the 3.3V at any time during the power up. This is because the 2.5V supply is generated from the 3.3V supply when the internal voltage regulator control logic is being used. Figure 3 shows the internal LVR circuit. The 1.2V ramp is delayed internally to prevent it from exceeding the 2.5V and 3.3V supply at any time. The delay is proportional to the slope of the 3.3V ramp. The delay is approximated by Tramp(3.3V)*0.25 < Tdelay(1.2V) < Tramp(3.3V)*0.75. Tramp is defined to the ramp rate of the 3.3V input to the internal voltage regulator circuit. Figure 3. Power Supply Sequencing Voltage 3.3V LAN_PWR_GOOD 2.5V 1.2V 0 Minimum 80 ms Time • It is recommended that the voltage on a lower voltage rail never exceed the voltage on a higher voltage rail during power on. • There are no minimum time requirements between the voltage rails as long as they power up in sequence: 3.3V → 2.5V → 1.2V. • All 3 supplies must be stable for at least 80 ms before LAN_PWR_GOOD is asserted. 100 ms is preferable if possible. • A PCIe* reset must occur after LAN Power Good is active. 3.3.4.2 Internal LVR Power Down Sequencing There are no specific power down sequencing and tracking requirements for the 82573 device. The risk of latch-up or electrical overstress is small because the only charge storing in decoupling capacitors is left in the system. 21 82573—Datasheet 3.3.4.3 Internal Voltage Regulators Components for the 82573 Table 7. 82573 Bill of Materials (BOM) of Components for Internal Regulator Recommended Component Description Quantity Manufacturer Part Number Package PNP Transistor For 1.2V LVR 1 Philips BCP-69-16 SOT-223 PNP Transistor For 2.5V LVR 1 Philips BCP-69-16 SOT-223 3.3.4.4 2.5V Internal LVR Specification Table 8. 2.5V Internal LVR Specification1 Value Parameter Input Voltage Input Voltage Slew Rate Input Capacitance Units Minimum Maximum 3.0 3.6 ms 4.7 µF 10 mΩ Load Current 1 - A Output Voltage Tolerance -5 +5 % Output Capacitance 4.7 VOUT = 2.500 V µF Output Capacitance ESR 10 mΩ Current Consumption During Power Up 0.5 mA Current Consumption During Power Down 0.5 mA Maximum Undershoot < 10 % of nominal supply Peak to Peak Output Ripple 120 mV ±60 mV at 20 MHz bandwidth 20 dB PSRR External PNP hFE 100 1.

These series resistors dissipate a portion of the power that would otherwise be dissipated by the PNP devices. The value and power rating of the resistors must be carefully chosen to balance thermal limits against the PNP characteristics against total current draw. The regulator must never drop below the minimum Vce and out of the linear region. The effective resistance of the pass resistors should equal approximately 1 Ω and have a combined power dissipation rating of 0.5 Watts for the 82573. Figure 4 shows the recommended implementation. 24 Datasheet—82573 Figure 4. 82573 2.5V and 1.2V LVR Schematic 2.5V Voltage Regulator Intel recommends using 40uF at the emitter of Q3 on the 3.3V rail.
