Electrical Specifications 2 Electrical Specifications This chapter describes the electrical characteristics of the processor interfaces and signals. DC electrical characteristics are provided. 2.1 Power and Ground Lands The processor has VCC (power), VTT, and VSS (ground) inputs for on-chip power distribution. All power lands must be connected to VCC, while all VSS lands must be connected to a system ground plane.
Electrical Specifications 2.2.3 FSB Decoupling The processor integrates signal termination on the die. In addition, some of the high frequency capacitance required for the FSB is included on the processor package. However, additional high frequency capacitance must be added to the motherboard to properly decouple the return currents from the front side bus. Bulk decoupling must also be provided by the motherboard for proper [A]GTL+ bus operation. 2.

Land Listing and Signal Descriptions 4.2 Alphabetical Signals Reference Table 24. Signal Description (Sheet 1 of 10) Name A[35:3]# Type Input/ Output Description A[35:3]# (Address) define a 236-byte physical memory address space. In sub-phase 1 of the address phase, these signals transmit the address of a transaction. In sub-phase 2, these signals transmit transaction type information. These signals must connect the appropriate pins/lands of all agents on the processor FSB.
Land Listing and Signal Descriptions Table 24. Signal Description (Sheet 2 of 10) Name Type Description BPM[5:0]# (Breakpoint Monitor) are breakpoint and performance monitor signals. They are outputs from the processor which indicate the status of breakpoints and programmable counters used for monitoring processor performance. BPM[5:0]# should connect the appropriate pins/lands of all processor FSB agents. BPM[5:0]# Input/ Output BPM4# provides PRDY# (Probe Ready) functionality for the TAP port.
Land Listing and Signal Descriptions Table 24. Signal Description (Sheet 3 of 10) Name Type Description D[63:0]# (Data) are the data signals. These signals provide a 64bit data path between the processor FSB agents, and must connect the appropriate pins/lands on all such agents. The data driver asserts DRDY# to indicate a valid data transfer. D[63:0]# are quad-pumped signals and will, thus, be driven four times in a common clock period.
Land Listing and Signal Descriptions Table 24. Signal Description (Sheet 4 of 10) Name Type Description Input DEFER# is asserted by an agent to indicate that a transaction cannot be ensured in-order completion. Assertion of DEFER# is normally the responsibility of the addressed memory or input/ output agent. This signal must connect the appropriate pins/lands of all processor FSB agents.
Land Listing and Signal Descriptions Table 24. Signal Description (Sheet 5 of 10) Name Type Description FERR#/PBE# Output FERR#/PBE# (floating point error/pending break event) is a multiplexed signal and its meaning is qualified by STPCLK#. When STPCLK# is not asserted, FERR#/PBE# indicates a floating-point error and will be asserted when the processor detects an unmasked floating-point error.
Land Listing and Signal Descriptions Table 24. Signal Description (Sheet 6 of 10) Name ITP_CLK[1:0] LINT[1:0] Type Description Input ITP_CLK[1:0] are copies of BCLK that are used only in processor systems where no debug port is implemented on the system board. ITP_CLK[1:0] are used as BCLK[1:0] references for a debug port implemented on an interposer. If a debug port is implemented in the system, ITP_CLK[1:0] are no connects in the system. These are not processor signals.
Land Listing and Signal Descriptions Table 24. Signal Description (Sheet 7 of 10) Name PWRGOOD Type Input Description PWRGOOD (Power Good) is a processor input. The processor requires this signal to be a clean indication that the clocks and power supplies are stable and within their specifications. ‘Clean’ implies that the signal will remain low (capable of sinking leakage current), without glitches, from the time that the power supplies are turned on until they come within specification.
Land Listing and Signal Descriptions Table 24. Signal Description (Sheet 8 of 10) Name SLP# SMI# Type Description Input SLP# (Sleep), when asserted in Extended Stop Grant or Stop Grant state, causes the processor to enter the Sleep state. In the Sleep state, the processor stops providing internal clock signals to all units, leaving only the Phase-Locked Loop (PLL) still operating. Processors in this state will not recognize snoops or interrupts.
Land Listing and Signal Descriptions Table 24. Signal Description (Sheet 9 of 10) Name Type Description Output In the event of a catastrophic cooling failure, the processor will automatically shut down when the silicon has reached a temperature approximately 20 °C above the maximum TC. Assertion of THERMTRIP# (Thermal Trip) indicates the processor junction temperature has reached a level beyond where permanent silicon damage may occur.
Land Listing and Signal Descriptions Table 24. Signal Description (Sheet 10 of 10) Name Type Description VID[7:0] Output The VID (Voltage ID) signals are used to support automatic selection of power supply voltages (VCC). Refer to the Voltage Regulator Design Guide for more information. The voltage supply for these signals must be valid before the VR can supply VCC to the processor. Conversely, the VR output must be disabled until the voltage supply for the VID signals becomes valid.

Thermal Specifications and Design Considerations 5 Thermal Specifications and Design Considerations 5.1 Processor Thermal Specifications The processor requires a thermal solution to maintain temperatures within the operating limits as set forth in Section 5.1.1. Any attempt to operate the processor outside these operating limits may result in permanent damage to the processor and potentially other components within the system.
Thermal Specifications and Design Considerations The case temperature is defined at the geometric top center of the processor. Analysis indicates that real applications are unlikely to cause the processor to consume maximum power dissipation for sustained time periods. Intel recommends that complete thermal solution designs target the Thermal Design Power (TDP) indicated in Table 25 instead of the maximum processor power consumption.
Thermal Specifications and Design Considerations Table 26. Figure 13. Processor Thermal Profile Power (W) Maximum Tc (°C) Power Maximum Tc (°C) Power Maximum Tc (°C) 0 44.9 24 55.7 48 66.5 2 45.8 26 56.6 50 67.4 4 46.7 28 57.5 52 68.3 6 47.6 30 58.4 54 69.2 8 48.5 32 59.3 56 70.1 10 49.4 34 60.2 58 71.0 12 50.3 36 61.1 60 71.9 14 51.2 38 62.0 62 72.8 16 52.1 40 62.9 64 73.7 18 53.0 42 63.8 65 74.1 20 53.9 44 64.7 22 54.8 46 65.
Thermal Specifications and Design Considerations 5.1.2 Thermal Metrology The maximum and minimum case temperatures (TC) for the processor is specified in Table 25. This temperature specification is meant to help ensure proper operation of the processor. Figure 14 illustrates where Intel recommends TC thermal measurements should be made. For detailed guidelines on temperature measurement methodology, refer to the appropriate Thermal and Mechanical Design Guidelines (see Section 1.2). Figure 14.
Thermal Specifications and Design Considerations periods of TCC activation is expected to be so minor that it would be immeasurable. An under-designed thermal solution that is not able to prevent excessive activation of the TCC in the anticipated ambient environment may cause a noticeable performance loss, and in some cases may result in a TC that exceeds the specified maximum temperature and may affect the long-term reliability of the processor.
Thermal Specifications and Design Considerations Figure 15. Thermal Monitor 2 Frequency and Voltage Ordering TTM2 Temperature fMAX fTM2 Frequency VID VIDTM2 VID PROCHOT# The PROCHOT# signal is asserted when a high temperature situation is detected, regardless of whether Thermal Monitor or Thermal Monitor 2 is enabled. It should be noted that the Thermal Monitor 2 TCC cannot be activated using the ondemand mode.
Thermal Specifications and Design Considerations 5.2.4 PROCHOT# Signal An external signal, PROCHOT# (processor hot), is asserted when the processor core temperature has reached its maximum operating temperature. If the Thermal Monitor is enabled (note that the Thermal Monitor must be enabled for the processor to be operating within specification), the TCC will be active when PROCHOT# is asserted. The processor can be configured to generate an interrupt upon the assertion or deassertion of PROCHOT#.
Thermal Specifications and Design Considerations 5.3 Platform Environment Control Interface (PECI) 5.3.1 Introduction PECI offers an interface for thermal monitoring of Intel processor and chipset components. It uses a single wire, thus alleviating routing congestion issues. PECI uses CRC checking on the host side to ensure reliable transfers between the host and client devices. Also, data transfer speeds across the PECI interface are negotiable within a wide range (2 Kbps to 2 Mbps).
Thermal Specifications and Design Considerations 5.3.2 PECI Specifications 5.3.2.1 PECI Device Address The PECI register resides at address 30h. 5.3.2.2 PECI Command Support PECI command support is covered in detail in the Platform Environment Control Interface Specification. Refer to this document for details on supported PECI command function and codes. 5.3.2.
Thermal Specifications and Design Considerations 84 Datasheet
Features 6 Features 6.1 Power-On Configuration Options Several configuration options can be configured by hardware. The processor samples the hardware configuration at reset, on the active-to-inactive transition of RESET#. For specifications on these options, refer to Table 28. The sampled information configures the processor for subsequent operation. These configuration options cannot be changed except by another reset.
Features Figure 17.
Features The return from a System Management Interrupt (SMI) handler can be to either Normal Mode or the HALT powerdown state. See the Intel Architecture Software Developer's Manual, Volume 3B: System Programming Guide, Part 2 for more information. The system can generate a STPCLK# while the processor is in the HALT powerdown state. When the system deasserts the STPCLK# interrupt, the processor will return execution to the HALT state. While in HALT powerdown state, the processor will process bus snoops.
Features 6.2.3.2 Extended Stop Grant State Extended Stop Grant is a low power state entered when the STPCLK# signal is asserted and Extended Stop Grant has been enabled using the BIOS. The processor will automatically transition to a lower frequency and voltage operating point before entering the Extended Stop Grant state. When entering the low power state, the processor will first switch to the lower bus ratio and then transition to the lower VID.
Features behavior.If RESET# is driven active while the processor is in the Sleep state, and held active as specified in the RESET# pin specification, then the processor will reset itself, ignoring the transition through the Stop-Grant state. If RESET# is driven active while the processor is in the Sleep state, the SLP# and STPCLK# signals should be deasserted immediately after RESET# is asserted to ensure the processor correctly executes the Reset sequence.
Features In response to entering Deeper Sleep, the processor drives the VID code corresponding to the Deeper Sleep core voltage on the VID pins. Unlike typical Dynamic VID changes (where the steps are single VID steps) the processor will perform a VID jump on the order of 100 mV. To support the Deeper Sleep State the platform must use a VRD 11.1 compliant solution. 6.2.8 Enhanced Intel SpeedStep® Technology The processor supports Enhanced Intel SpeedStep Technology.
Boxed Processor Specifications 7 Boxed Processor Specifications 7.1 Introduction The processor will also be offered as an Intel boxed processor. Intel boxed processors are intended for system integrators who build systems from baseboards and standard components. The boxed processor will be supplied with a cooling solution. This chapter documents baseboard and system requirements for the cooling solution that will be supplied with the boxed processor.
Boxed Processor Specifications 7.2 Mechanical Specifications 7.2.1 Boxed Processor Cooling Solution Dimensions This section documents the mechanical specifications of the boxed processor. The boxed processor will be shipped with an unattached fan heatsink. Figure 18 shows a mechanical representation of the boxed processor. Clearance is required around the fan heatsink to ensure unimpeded airflow for proper cooling.
Boxed Processor Specifications Figure 21. Overall View Space Requirements for the Boxed Processor 7.2.2 Boxed Processor Fan Heatsink Weight The boxed processor fan heatsink will not weigh more than 450 grams. See Chapter 5 and the appropriate Thermal and Mechanical Design Guidelines (see Section 1.2) for details on the processor weight and heatsink requirements. 7.2.
Boxed Processor Specifications The boxed processor's fanheat sink requires a constant +12 V supplied to pin 2 and does not support variable voltage control or 3-pin PWM control. The power header on the baseboard must be positioned to allow the fan heatsink power cable to reach it. The power header identification and location should be documented in the platform documentation, or on the system board itself. Figure 23 shows the location of the fan power connector relative to the processor socket.
