Signal Description (Sheet 1 of 9) 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 25. Signal Description (Sheet 2 of 9) 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 25. Signal Description (Sheet 3 of 9) 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 25. Signal Description (Sheet 4 of 9) Name DEFER# DRDY# 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 9) Name HIT# HITM# IERR# Type Input/ Output Input/ Output Output Description HIT# (Snoop Hit) and HITM# (Hit Modified) convey transaction snoop operation results. Any FSB agent may assert both HIT# and HITM# together to indicate that it requires a snoop stall, which can be continued by reasserting HIT# and HITM# together. IERR# (Internal Error) is asserted by a processor as the result of an internal error.
Land Listing and Signal Descriptions Table 25. Signal Description (Sheet 6 of 9) Name Type Description LOCK# indicates to the system that a transaction must occur atomically. This signal must connect the appropriate pins/lands of all processor FSB agents. For a locked sequence of transactions, LOCK# is asserted from the beginning of the first transaction to the end of the last transaction. LOCK# Input/ Output MSID[1:0] Output These signals indicate the Market Segment for the processor.
Land Listing and Signal Descriptions Table 25. Signal Description (Sheet 7 of 9) Name Type Description RS[2:0]# Input RS[2:0]# (Response Status) are driven by the response agent (the agent responsible for completion of the current transaction), and must connect the appropriate pins/lands of all processor FSB agents. SKTOCC# Output SKTOCC# (Socket Occupied) will be pulled to ground by the processor. System board designers may use this signal to determine if the processor is present.
Land Listing and Signal Descriptions Table 25. Signal Description (Sheet 8 of 9) Name THERMTRIP# 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 25. Signal Description (Sheet 9 of 9) Name Type Description VRDSEL Input This input should be left as a no connect in order for the processor to boot. The processor will not boot on legacy platforms where this land is connected to VSS. VSS Input VSS are the ground pins for the processor and should be connected to the system ground plane. VSSA Input VSSA is the isolated ground for internal PLLs.
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 described 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 26 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 26. This temperature specification is meant to help ensure proper operation of the processor. Figure 17 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 17.
Thermal Specifications and Design Considerations 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 18. 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. The Thermal Monitor TCC, however, can be activated through the use of 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 Thermal Diode The processor incorporates an on-die PNP transistor where the base emitter junction is used as a thermal "diode", with its collector shorted to ground. A thermal sensor located on the system board may monitor the die temperature of the processor for thermal management and fan speed control. Table 29,Table 30, and Table 31 provide the "diode" parameter and interface specifications.

Thermal Specifications and Design Considerations 5.4 Platform Environment Control Interface (PECI) 5.4.1 Introduction PECI offers an interface for thermal monitoring of Intel processor and chipset components. It uses a single wire, thus alleviating routing congestion issues. Figure 19 shows an example of the PECI topology in a system. PECI uses CRC checking on the host side to ensure reliable transfers between the host and client devices.

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 33. The sampled information configures the processor for subsequent operation. These configuration options cannot be changed except by another reset.
Features 6.2 Clock Control and Low Power States The processor allows the use of AutoHALT and Stop-Grant states to reduce power consumption by stopping the clock to internal sections of the processor, depending on each particular state. See Figure 22 for a visual representation of the processor low power states. Figure 22.
Features 6.2.2.1 HALT Powerdown State HALT is a low power state entered when all the processor cores have executed the HALT or MWAIT instructions. When one of the processor cores executes the HALT instruction, that processor core is halted, however, the other processor continues normal operation. The processor will transition to the Normal state upon the occurrence of SMI#, INIT#, or LINT[1:0] (NMI, INTR). RESET# will cause the processor to immediately initialize itself.
Features 6.2.3.1 Stop-Grant State When the STPCLK# signal is asserted, the Stop Grant state of the processor is entered 20 bus clocks after the response phase of the processor-issued Stop Grant Acknowledge special bus cycle. Since the GTL+ signals receive power from the FSB, these signals should not be driven (allowing the level to return to VTT) for minimum power drawn by the termination resistors in this state. In addition, all other input signals on the FSB should be driven to the inactive state.
Features 6.2.4.2 Extended HALT Snoop State, Extended Stop Grant Snoop State The processor will remain in the lower bus ratio and VID operating point of the Extended HALT state or Extended Stop Grant state.
