Introduction 12 Datasheet
Electrical Specifications 2 Electrical Specifications 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. The processor VCC lands must be supplied the voltage determined by the Voltage IDentification (VID) lands. The signals denoted as VTT provide termination for the front side bus and power to the I/O buffers.
Electrical Specifications 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. Decoupling guidelines are described in the appropriate platform design guidelines. 2.3 Voltage Identification The Voltage Identification (VID) specification for the processor is defined by the Voltage Regulator-Down (VRD) 11.0 Processor Power Delivery Design Guidelines For Desktop LGA775 Socket.

Electrical Specifications 2.4 Reserved, Unused, and TESTHI Signals All RESERVED lands must remain unconnected. Connection of these lands to VCC, VSS, VTT, or to any other signal (including each other) can result in component malfunction or incompatibility with future processors. See Chapter 4 for a land listing of the processor and the location of all RESERVED lands.
Electrical Specifications 2.6 Power Segment Identifier (PSID) Power Segment Identifier (PSID) is a mechanism to prevent booting under mismatched power requirement situations. The PSID mechanism enables BIOS to detect if the processor in use requires more power than the platform voltage regulator (VR) is capable of supplying. For example, a 130W TDP processor installed in a board with a 65W or 95W TDP capable VR may draw too much power and cause a potential VR issue. 2.
Electrical Specifications Storage within these limits will not affect the long-term reliability of the device. For functional operation, refer to the processor case temperature specifications. This rating applies to the processor and does not include any tray or packaging. Failure to adhere to this specification can affect the long term reliability of the processor. 4. 5. 2.7.2 DC Voltage and Current Specification Table 2-3.

Land Listing and Signal Descriptions 4.2 Alphabetical Signals Reference Table 4-3. 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 4-3. Signal Description (Sheet 2 of 10) Name Type Description BPM[5:0]# and BPMb[3:0]# (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]# and BPMb[3:0]# should connect the appropriate pins/lands of all processor FSB agents. BPM[3:0]# are associated with core 0.
Land Listing and Signal Descriptions Table 4-3. Signal Description (Sheet 3 of 10) Name Type Description D[63:0]# (Data) are the data signals. These signals provide a 64-bit 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 4-3. Signal Description (Sheet 4 of 10) Name DEFER# DPRSTP# 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.

Signal Description (Sheet 5 of 10) Name FCx FERR#/PBE# GTLREF[3:0] HIT# HITM# IERR# Type Other Output Input Input/ Output Input/ Output Output Description FC signals are signals that are available for compatibility with other processors. Refer to the appropriate platform design guide for more information on how these are connected on the motherboard.
Land Listing and Signal Descriptions Table 4-3. Signal Description (Sheet 6 of 10) Name INIT# Type Input Description INIT# (Initialization), when asserted, resets integer registers inside the processor without affecting its internal caches or floating-point registers. The processor then begins execution at the power-on Reset vector configured during power-on configuration. The processor continues to handle snoop requests during INIT# assertion.
Land Listing and Signal Descriptions Table 4-3. Signal Description (Sheet 7 of 10) Name Type Description PWRGOOD Input 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 4-3. Signal Description (Sheet 8 of 10) Name Type Description STPCLK# Input STPCLK# (Stop Clock), when asserted, causes the processor to enter a low power Stop-Grant state. The processor issues a Stop-Grant Acknowledge transaction, and stops providing internal clock signals to all processor core units except the FSB and APIC units. The processor continues to snoop bus transactions and service interrupts while in Stop-Grant state.
Land Listing and Signal Descriptions Table 4-3. Signal Description (Sheet 9 of 10) Name Description VCC Input VCC are the power pins for the processor. The voltage supplied to these pins is determined by the VID[7:0] pins. VCCA Input VCCA provides isolated power for internal PLLs on previous generation processors. It may be left as a No-Connect on boards supporting the Wolfdale processor.
Land Listing and Signal Descriptions Table 4-3. Signal Description (Sheet 10 of 10) Name Type Description Output The VTT_OUT_LEFT and VTT_OUT_RIGHT signals are included to provide a voltage supply for some signals that require termination to VTT on the motherboard. Refer to the appropriate platform design guide for details on implementation. Output The VTT_SEL signal is used to select the correct VTT voltage level for the processor.

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 5-1 instead of the maximum processor power consumption.

Thermal Specifications and Design Considerations 5.1.2 Thermal Metrology The maximum and minimum case temperatures (TC) for the processor is specified in Table 5-1. This temperature specification is meant to help ensure proper operation of the processor. Figure 5-3 illustrates where Intel recommends TC thermal measurements should be made. For detailed guidelines on temperature measurement methodology, refer to the Yorkfield Processor Thermal and Mechanical Design Guidelines Addendum. Figure 5-3.
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 5-4. 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 via the on demand 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 5.3.1.1 TCONTROL and TCC activation on PECI-Based Systems Fan speed control solutions based on PECI utilize a TCONTROL value stored in the processor IA32_TEMPERATURE_TARGET MSR. The TCONTROL MSR uses the same offset temperature format as PECI though it contains no sign bit. Thermal management devices should infer the TCONTROL value as negative.
Thermal Specifications and Design Considerations that fall under the specification, the PECI will always respond to requests and the protocol itself can be relied upon to detect any transmission failures. There are, however, certain scenarios where the PECI is know to be unresponsive. Prior to a power on RESET# and during RESET# assertion, PECI is not guaranteed to provide reliable thermal data.
Thermal Specifications and Design Considerations 86 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 6-1. The sampled information configures the processor for subsequent operation. These configuration options cannot be changed except by another reset.
Features Figure 6-1.
Features The system can generate a STPCLK# while the processor is in the HALT Power Down state. When the system deasserts the STPCLK# interrupt, the processor will return execution to the HALT state. While in HALT Power Down state, the processor will process bus snoops. 6.2.2.2 Extended HALT Powerdown State Extended HALT is a low power state entered when all processor cores have executed the HALT or MWAIT instructions and Extended HALT has been enabled via the BIOS.
Features 6.2.4.1 HALT Snoop State, Stop Grant Snoop State The processor will respond to snoop transactions on the FSB while in Stop-Grant state or in HALT Power Down state. During a snoop transaction, the processor enters the HALT Snoop State:Stop Grant Snoop state. The processor will stay in this state until the snoop on the FSB has been serviced (whether by the processor or another agent on the FSB).
