Introduction
The streaming SIMD extensions 2 (SSE2) enable break-through levels of performance in multimedia applications including 3-D graphics, video decoding/encoding, and speech recognition. The new packed double-precision floating-point instructions enhance performance for applications that require greater range and precision, including scientific and engineering applications and advanced 3-D geometry techniques, such as ray tracing. The Intel Pentium M Processor's 400-MHz FSB utilizes a split-transaction, deferred reply protocol. The 400-MHz FSB uses source-synchronous transfer (SST) of address and data to improve performance by transferring data four times per bus clock (4X data transfer rate, as in AGP 4X). Along with the 4X data bus, the address bus can deliver addresses two times per bus clock and is referred to as a "double-clocked" or 2X address bus. Working together, the 4X data bus and 2X address bus provide a data bus bandwidth of up to 3.2 GB/second. The FSB uses Advanced Gunning Transceiver Logic (AGTL+) signaling technology, a variant of GTL+ signaling technology with low power enhancements. The processor features Enhanced Intel SpeedStep(R) technology, which enables real-time dynamic switching between multiple voltage and frequency points. This results in optimal performance without compromising low power. The processor features the Auto Halt, Stop Grant, Deep Sleep, and Deeper Sleep low power states. The Intel Pentium M Processor utilizes socketable Micro Flip-Chip Pin Grid Array (MicroFCPGA) and surface mount Micro Flip-Chip Ball Grid Array (Micro-FCBGA) package technology. The Micro-FCPGA package plugs into a 479-hole, surface-mount, zero insertion force (ZIF) socket, which is referred to as the mPGA479M socket. Intel Pentium M processors with CPU Signature = 06D8h will also include the Execute Disable Bit capability. This feature combined with a support operating system allows memory to be marked as executable or non executable. If code attempts to run in non-executable memory the processor raises an error to the operating system. This feature can prevent some classes of viruses or worms that exploit buffer overrun vulnerabilities and can thus help improve the overall security of the system. See the Intel(R) Architecture Software Developer's Manual for more detailed information. Intel will validate this feature only on Intel 915 chipset family based platforms and recommends customers implement BIOS changes related to this feature, only on Intel 915 chipset family based platforms. Note: The term AGTL+ is used to refer to Assisted GTL+ signalling technology on some Intel processors.

Introduction
1.1
Terminology
Term # Definition A "#" symbol after a signal name refers to an active low signal, indicating a signal is in the active state when driven to a low level. For example, when RESET# is low, a reset has been requested. Conversely, when NMI is high, a nonmaskable interrupt has occurred. In the case of signals where the name does not imply an active state but describes part of a binary sequence (such as address or data), the "#" symbol implies that the signal is inverted. For example, D[3:0] = "HLHL" refers to a hex `A', and D[3:0]# = "LHLH" also refers to a hex "A" (H= High logic level, L= Low logic level). XXXX means that the specification or value is yet to be determined. Refers to the interface between the processor and system core logic (also known as the chipset components).

2.1
Low Power Features
Clock Control and Low Power States
The Intel Pentium M processor supports the AutoHALT Power-Down, Stop Grant, Sleep, Deep Sleep, and Deeper Sleep states for optimal power management. See Figure 2-1 for a visual representation of the processor low-power states. Figure 2-1. Clock Control States

2.1.1
Normal State
This is the normal operating state for the processor.
2.1.2
AutoHALT Power-Down State
AutoHALT Power-Down is a low-power state entered when the processor executes the HALT instruction. The processor will transition to the Normal state upon the occurrence of SMI#, INIT#, LINT[1:0] (NMI, INTR), or FSB interrupt message. RESET# will cause the processor to immediately initialize itself. A system management interrupt (SMI) handler will return execution to either Normal state or the AutoHALT Power-Down state. See the Intel Architecture Software Developer's Manual, Volume III: System Programmer's Guide for more information.
Intel(R) Pentium(R) M Processor on 90 nm Process with 2-MB L2 Cache Datasheet
11
Low Power Features
The system can generate a STPCLK# while the processor is in the AutoHALT Power-Down state. When the system deasserts the STPCLK# interrupt, the processor will return execution to the HALT state. While in AutoHALT Power-Down state, the processor will process bus snoops and interrupts.
2.1.3
Stop-Grant State
When the STPCLK# pin 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 AGTL+ signal pins receive power from the FSB, these pins should not be driven (allowing the level to return to VCCP) for minimum power drawn by the termination resistors in this state. In addition, all other input pins on the FSB should be driven to the inactive state. RESET# will cause the processor to immediately initialize itself, but the processor will stay in Stop-Grant state. A transition back to the Normal state will occur with the de-assertion of the STPCLK# signal. When re-entering the Stop-Grant state from the Sleep state, STPCLK# should be deasserted ten or more bus clocks after the de-assertion of SLP#. A transition to the HALT/Grant Snoop state will occur when the processor detects a snoop on the FSB (see Section 2.1.3). A transition to the Sleep state (see Section 2.1.5) will occur with the assertion of the SLP# signal. While in the Stop-Grant State, SMI#, INIT# and LINT[1:0] will be latched by the processor, and only serviced when the processor returns to the Normal State. Only one occurrence of each event will be recognized upon return to the Normal state. While in Stop-Grant state, the processor will process snoops on the FSB and it will latch interrupts delivered on the FSB. The PBE# signal can be driven when the processor is in Stop-Grant state. PBE# will be asserted if there is any pending interrupt latched within the processor. Pending interrupts that are blocked by the EFLAGS.IF bit being clear will still cause assertion of PBE#. Assertion of PBE# indicates to system logic that it should return the processor to the Normal state.
2.1.4
HALT/Grant Snoop State
The processor responds to snoop or interrupt transactions on the FSB while in Stop-Grant state or in AutoHALT Power-Down state. During a snoop or interrupt transaction, the processor enters the HALT/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) or the interrupt has been latched. After the snoop is serviced or the interrupt is latched, the processor will return to the Stop-Grant state or AutoHALT Power-Down state, as appropriate.
2.1.5
Sleep State
A low power state in which the processor maintains its context, maintains the phase-locked loop (PLL), and has stopped all internal clocks. The Sleep state can be entered only from Stop-Grant state. Once in the Stop-Grant state, the processor will enter the Sleep state upon the assertion of the
12
Intel(R) Pentium(R) M Processor on 90 nm Process with 2-MB L2 Cache Datasheet
Low Power Features
SLP# signal. The SLP# pin should only be asserted when the processor is in the Stop Grant state. SLP# assertions while the processor is not in the Stop-Grant state is out of specification and may result in unapproved operation. Snoop events that occur while in Sleep State or during a transition into or out of Sleep state will cause unpredictable behavior. In the Sleep state, the processor is incapable of responding to snoop transactions or latching interrupt signals. No transitions or assertions of signals (with the exception of SLP#, DPSLP# or RESET#) are allowed on the FSB while the processor is in Sleep state. Any transition on an input signal before the processor has returned to Stop-Grant state will result in unpredictable 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 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. While in the Sleep state, the processor is capable of entering an even lower power state, the Deep Sleep state by asserting the DPSLP# pin. (See Section 2.1.6.) While the processor is in the Sleep state, the SLP# pin must be deasserted if another asynchronous FSB event needs to occur.
2.1.6
Deep Sleep State
Deep Sleep state is a very low power state the processor can enter while maintaining context. Deep Sleep state is entered by asserting the DPSLP# pin while in the Sleep state. BCLK may be stopped during the Deep Sleep state for additional platform level power savings. BCLK stop/restart timings on 855PM and Intel 855GM chipset-based platforms are as follows:
* Deep Sleep entry - DPSLP# and CPU_STP# are asserted simultaneously. The platform clock
chip will stop/tristate BCLK within 2 BCLKs +/- a few nanoseconds.
* Deep Sleep exit - DPSLP# and CPU_STP# are deasserted simultaneously. The platform clock
chip will drive BCLK to differential DC levels within 2-3 ns and starts toggling BCLK 2-6 BCLK periods later. To re-enter the Sleep state, the DPSLP# pin must be deasserted. BCLK can be restarted after DPSLP# deassertion, as described above. A period of 30 microseconds (to allow for PLL stabilization) must occur before the processor can be considered to be in the Sleep State. Once in the Sleep state, the SLP# pin must be deasserted to re-enter the Stop-Grant state. While in Deep Sleep state, the processor is incapable of responding to snoop transactions or latching interrupt signals. No transitions of signals are allowed on the FSB while the processor is in Deep Sleep state. Any transition on an input signal before the processor has returned to Stop-Grant state will result in unpredictable behavior. When the processor is in Deep Sleep state, it will not respond to interrupts or snoop transactions.

Low Power Features
2.1.7
Deeper Sleep State
The Deeper Sleep state is the lowest power state the processor can enter. This state is functionally identical to the Deep Sleep state but at a lower core voltage. The control signals to the voltage regulator to initiate a transition to the Deeper Sleep state are provided on the platform. Please refer to the platform design guides listed in Table 1-1.
2.2
Enhanced Intel SpeedStep(R) Technology
The Intel Pentium M processor features Enhanced Intel SpeedStep(R) technology. Unlike previous implementations of Intel SpeedStep technology, this technology enables the processor to switch between multiple frequency and voltage points instead of two. This will enable superior performance with optimal power savings. Switching between states is software controlled unlike previous implementations where the GHI# pin is used to toggle between two states. Following are the key features of Enhanced Intel SpeedStep technology:
* Multiple voltage/frequency operating points provide optimal performance at the lowest power. * Voltage/Frequency selection is software controlled by writing to processor MSR's (Model
Specific Registers) thus eliminating chipset dependency. -- If the target frequency is higher than the current frequency, Vcc is ramped up by placing a new value on the VID pins and the PLL then locks to the new frequency. -- If the target frequency is lower than the current frequency, the PLL locks to the new frequency and the Vcc is changed through the VID pin mechanism. -- Software transitions are accepted at any time. If a previous transition is in progress, the new transition is deferred until its completion.
* The processor controls voltage ramp rates internally to ensure glitch free transitions. * Low transition latency and large number of transitions possible per second.
-- Processor core (including L2 cache) is unavailable for up to 10 s during the frequency transition -- The bus protocol (BNR# mechanism) is used to block snooping
* No bus master arbiter disable required prior to transition and no processor cache flush
necessary.
* Improved Intel(R) Thermal Monitor mode.
-- When the on-die thermal sensor indicates that the die temperature is too high, the processor can automatically perform a transition to a lower frequency/voltage specified in a software programmable MSR. -- The processor waits for a fixed time period. If the die temperature is down to acceptable levels, an up transition to the previous frequency/voltage point occurs. -- An interrupt is generated for the up and down Intel Thermal Monitor transitions enabling better system level thermal management.

Low Power Features
2.3
Front Side Bus Low Power Enhancements
The Intel Pentium M processor incorporates the following front side bus (processor system bus) low power enhancements:
* * * *
Dynamic FSB Power Down BPRI# control for address and control input buffers Dynamic On Die Termination disabling Low VCCP (I/O termination voltage)
The Intel Pentium M processor incorporates the DPWR# signal that controls the data bus input buffers on the processor. The DPWR# signal disables the buffers when not used and activates them only when data bus activity occurs, resulting in significant power savings with no performance impact. BPRI# control also allows the processor address and control input buffers to be turned off when the BPRI# signal is inactive. The on-die termination on the processor FSB buffers is disabled when the signals are driven low, resulting in additional power savings. The low I/O termination voltage is on a dedicated voltage plane independent of the core voltage, enabling low I/O switching power at all times.
2.4
Processor Power Status Indicator (PSI#) Signal
The Intel Pentium M processor incorporates the PSI# signal that is asserted when the processor is in a low power (Deep Sleep or Deeper Sleep) state. This signal is asserted upon Deep Sleep entry and deasserted upon exit. PSI# can be used to improve the light load efficiency of the voltage regulator, resulting in platform power savings and extended battery life. PSI# can also be used to simplify voltage regulator designs since it removes the need for integrated 100 s timers required to mask the PWRGOOD signal during Deeper Sleep transitions. It also helps loosen PWRGOOD monitoring requirements in the Deeper Sleep state.

3.1
Electrical Specifications
Power and Ground Pins
For clean, on-chip power distribution, the Intel Pentium M processor has a large number of VCC (power) and VSS (ground) inputs. All power pins must be connected to VCC power planes while all VSS pins must be connected to system ground planes. Use of multiple power and ground planes is recommended to reduce I*R drop. Please refer to the platform design guides for more details. The processor VCC pins must be supplied the voltage determined by the VID (Voltage ID) pins.
3.1.1
FSB Clock (BCLK[1:0]) and Processor Clocking
BCLK[1:0] directly controls the system bus interface speed as well as the core frequency of the processor. As in previous generation processors, the Intel Pentium M processor core frequency is a multiple of the BCLK[1:0] frequency. In regards to processor clocking, the Intel Pentium M processor uses a differential clocking implementation.
3.2
Voltage Identification
The Intel Pentium M processor uses six voltage identification pins, VID[5:0], to support automatic selection of power supply voltages. The VID pins for the Intel Pentium M processor are CMOS outputs driven by the processor VID circuitry. Table 3-1 specifies the voltage level corresponding to the state of VID[5:0]. A "1" in this refers to a high-voltage level and a "0" refers to low-voltage level.

3.3
Catastrophic Thermal Protection
The Intel Pentium M processor supports the THERMTRIP# signal for catastrophic thermal protection. An external thermal sensor should also be used to protect the processor and the system against excessive temperatures. Even with the activation of THERMTRIP#, which halts all processor internal clocks and activity, leakage current can be high enough such that the processor cannot be protected in all conditions without the removal of power to the processor. If the external thermal sensor detects a catastrophic processor temperature of 125 C (maximum), or if the THERMTRIP# signal is asserted, the VCC supply to the processor must be turned off within 500 ms to prevent permanent silicon damage due to thermal runaway.

3.4
Signal Terminations and Unused Pins
All RSVD (RESERVED) pins must remain unconnected. Connection of these pins to VCC, VSS, or to any other signal (including each other) can result in component malfunction or incompatibility with future Intel Pentium M processors. See Section 4.2 for a pin listing of the processor and the location of all RSVD pins. For reliable operation, always connect unused inputs or bidirectional signals to an appropriate signal level. Unused active low AGTL+ inputs may be left as no connects if AGTL+ termination is provided on the processor silicon. Unused active high inputs should be connected through a resistor to ground (VSS). Unused outputs can be left unconnected. For details on signal terminations, please refer to the platform design guides. The TEST1 and TEST2 pins must have a stuffing option connection to VSS separately via 1-k, pull-down resistors.
3.5
FSB Frequency Select Signals (BSEL[1:0])
These signals are used to select the FSB clock frequency. They should be connected between the processor and the chipset MCH and clock generator on Intel 915 chipset family based platforms. These signals must be left unconnected on platforms designed with the Intel 855 chipset family. On these platforms, FSB clock frequency should be configured on the motherboard.
3.6
FSB Signal Groups
In order to simplify the following discussion, the FSB signals have been combined into groups by buffer type. AGTL+ input signals have differential input buffers, which use GTLREF as a reference level. In this document, the term "AGTL+ Input" refers to the AGTL+ input group as well as the AGTL+ I/O group when receiving. Similarly, "AGTL+ Output" refers to the AGTL+ output group as well as the AGTL+ I/O group when driving. With the implementation of a source synchronous data bus comes the need to specify two sets of timing parameters. One set is for common clock signals which are dependant upon the rising edge of BCLK0 (ADS#, HIT#, HITM#, etc.) and the second set is for the source synchronous signals which are relative to their respective strobe lines (data and address) as well as the rising edge of BCLK0. Asychronous signals are still present (A20M#, IGNNE#, etc.) and can become active at any time during the clock cycle. Table 3-2 identifies which signals are common clock, source synchronous, and asynchronous.

NOTES: 1. Refer to Chapter 4 for signal descriptions and termination requirements. 2. BPM[2:0}# and PRDY# are AGTL+ output only signals. 3. In processor systems where there is no debug port implemented on the system board, these signals are used to support a debug port interposer. In systems with the debug port implemented on the system board, these signals are no connects.
3.7
CMOS Signals
CMOS input signals are shown in Table 3-2. Legacy output FERR#, IERR# and other non-AGTL+ signals (THERMTRIP# and PROCHOT#) utilize Open Drain output buffers. These signals do not have setup or hold time specifications in relation to BCLK[1:0]. However, all of the CMOS signals are required to be asserted for at least three BCLKs in order for the processor to recognize them. See Section 3.9 for the DC and AC specifications for the CMOS signal groups.

Maximum Ratings
Table 3-3 lists the processor's maximum environmental stress ratings. The processor should not receive a clock while subjected to these conditions. Functional operating parameters are listed in the AC and DC tables. Extended exposure to the maximum ratings may affect device reliability. Furthermore, although the processor contains protective circuitry to resist damage from electro static discharge (ESD), one should always take precautions to avoid high static voltages or electric fields.

Processor DC Specifications
The processor DC specifications in this section are defined at the processor core (pads) unless noted otherwise. See Table 27 for the pin signal definitions and signal pin assignments. The DC specifications for these signals are listed in Table 3-21 and Table 3-22. Table 3-4 through Table 3-22 list the DC specifications for the Intel Pentium M processor and are valid only while meeting specifications for junction temperature, clock frequency, and input voltages. The Highest Frequency mode (HFM) and Lowest Frequency mode (LFM) refer to the highest and lowest core operating frequencies supported on the processor. Active mode load line specifications apply in all states except in the Deep Sleep and Deeper Sleep states. VCC,BOOT is the

NOTES: 1. The typical values shown are the VID encoded voltages. Static and ripple tolerances (for minimum and maximum voltages) are defined in the load line tables i.e., Table 3-5 through Table 3-18. Adherence to loadline specifications for the Intel(R) Pentium(R) M Processor is required to ensure reliable processor operation. 2. The voltage specifications are assumed to be measured at a via on the motherboard's opposite side of the processor's socket (or BGA) ball with a 100-MHz bandwidth oscilloscope, 1.5-pF maximum probe capacitance, and 1-Mohm minimum impedance. The maximum length of ground wire on the probe should be less than 5 mm. Ensure external noise from the system is not coupled in the scope probe. 3. Specified at VCC,STATIC (nominal) under maximum signal loading conditions. 4. Specified at the VID voltage. 5. The ICCDES(max) specification comprehends future processor HFM frequencies. Platforms should be designed to this specification. 6. Based on simulations and averaged over the duration of any change in current. Specified by design/ characterization at nominal VCC. Not 100% tested. 7. Measured at the bulk capacitors on the motherboard. 8. Intel Pentium M Processors LV and ULV will support VCCA supply voltages of both 1.8 V +/- 5% and1.5 V +/ - 5%. 9. Deeper sleep voltage of 0.726V (typical) is supported on LV and ULV Pentium M processors with CPU signature =06D8h. A typical voltage setting between 0.726V and 0.748V maybe used but the minimum and maximum voltages specified in Table 5 should not be exceeded.

Package Mechanical Specifications and Pin Information
The Intel Pentium M processor is available in 478-pin, Micro-FCPGA and 479-ball, MicroFCBGA packages. Different views of the Micro-FCPGA package are shown in Figure 4-1 through Figure 4-3. Package dimensions are shown in Table 4-1. Different views of the Micro-FCBGA package are shown in Figure 4-4 through Figure 4-6. Package dimensions are shown in Table 4-2. The Micro-FCBGA package may have capacitors placed in the area surrounding the die. Because the die-side capacitors are electrically conductive, and only slightly shorter than the die height, care should be taken to avoid contacting the capacitors with electrically conductive materials. Doing so may short the capacitors, and possibly damage the device or render it inactive. The use of an insulating material between the capacitors and any thermal solution should be considered to prevent capacitor shorting. Figure 4-1. Micro-FCPGA Package Top and Bottom Isometric Views

Alphabetical Signals Reference
Name A[31:3]# Type Input/ Output
32
Table 4-5. Signal Description (Sheet 1 of 7)
Description A[31:3]# (Address) define a 2 -byte physical memory address space. In subphase 1 of the address phase, these pins transmit the address of a transaction. In sub-phase 2, these pins transmit transaction type information. These signals must connect the appropriate pins of both agents on the Intel(R)Pentium(R) M FSB. A[31:3]# are source synchronous signals and are latched into the receiving buffers by ADSTB[1:0]#. Address signals are used as straps which are sampled before RESET# is deasserted. If A20M# (Address-20 Mask) is asserted, the processor masks physical address bit 20 (A20#) before looking up a line in any internal cache and before driving a read/write transaction on the bus. Asserting A20M# emulates the 8086 processor's address wrap-around at the 1-Mbyte boundary. Assertion of A20M# is only supported in real mode. A20M# is an asynchronous signal. However, to ensure recognition of this signal following an Input/Output write instruction, it must be valid along with the TRDY# assertion of the corresponding Input/Output Write bus transaction. ADS# (Address Strobe) is asserted to indicate the validity of the transaction address on the A[31:3]# and REQ[4:0]# pins. All bus agents observe the ADS# activation to begin parity checking, protocol checking, address decode, internal snoop, or deferred reply ID match operations associated with the new transaction. Address strobes are used to latch A[31:3]# and REQ[4:0]# on their rising and falling edges. Strobes are associated with signals as shown below.

The differential pair BCLK (Bus Clock) determines the FSB frequency. All FSB agents must receive these signals to drive their outputs and latch their inputs. All external timing parameters are specified with respect to the rising edge of BCLK0 crossing VCROSS. BNR# (Block Next Request) is used to assert a bus stall by any bus agent who is unable to accept new bus transactions. During a bus stall, the current bus owner cannot issue any new transactions. BPM[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[3:0]# should connect the appropriate pins of all Intel(R) Pentium(R) M FSB agents.This includes debug or performance monitoring tools. Please refer to the platform design guides for more detailed information. BPRI# (Bus Priority Request) is used to arbitrate for ownership of the FSB. It must connect the appropriate pins of both FSB agents. Observing BPRI# active (as asserted by the priority agent) causes the other agent to stop issuing new requests, unless such requests are part of an ongoing locked operation. The priority agent keeps BPRI# asserted until all of its requests are completed, then releases the bus by deasserting BPRI#. BR0# is used by the processor to request the bus. The arbitration is done between Intel(R)Pentium(R) M (Symmetric Agent) and Intel 855 chipset family MCH-M (High Priority Agent).

Name BSEL[1:0] Type Output Description These signals are used to select the FSB clock frequency. They should be connected between the processor and the chipset MCH and clock generator on Intel 915 chipset family based platforms. These signals must be left unconnected on platforms designed with the Intel 855 chipset family. On these platforms, FSB clock frequency should be configured on the motherboard. COMP[3:0] must be terminated on the system board using precision (1% tolerance) resistors. Refer to the platform design guides for more details on implementation. D[63:0]# (Data) are the data signals. These signals provide a 64-bit data path between the FSB agents, and must connect the appropriate pins on both 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. D[63:0]# are latched off the falling edge of both DSTBP[3:0]# and DSTBN[3:0]#. Each group of 16 data signals correspond to a pair of one DSTBP# and one DSTBN#. The following table shows the grouping of data signals to data strobes and DINV#. Quad-Pumped Signal Groups Data Group D[15:0]# D[31:16]# D[47:32]# D[63:48]# DSTBN#/ DSTBP# 0 1 2 3 DINV# 0 1 2 3

Input/ Output
Furthermore, the DINV# pins determine the polarity of the data signals. Each group of 16 data signals corresponds to one DINV# signal. When the DINV# signal is active, the corresponding data group is inverted and therefore sampled active high. DBR# Output DBR# (Data Bus Reset) is used only in processor systems where no debug port is implemented on the system board. DBR# is used by a debug port interposer so that an in-target probe can drive system reset. If a debug port is implemented in the system, DBR# is a no connect in the system. DBR# is not a processor signal. DBSY# (Data Bus Busy) is asserted by the agent responsible for driving data on the FSB to indicate that the data bus is in use. The data bus is released after DBSY# is deasserted. This signal must connect the appropriate pins on both FSB agents. DEFER# is asserted by an agent to indicate that a transaction cannot be guaranteed 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 of both FSB agents.

Name DINV[3:0]# Type Input/ Output Description DINV[3:0]# (Data Bus Inversion) are source synchronous and indicate the polarity of the D[63:0]# signals. The DINV[3:0]# signals are activated when the data on the data bus is inverted.

DPSLP# when asserted on the platform causes the processor to transition from the Sleep State to the Deep Sleep state. In order to return to the Sleep state, DPSLP# must be deasserted. DPSLP# is driven by the ICH4-M component and also connects to the Intel 855 chipset family MCH-M component. DPWR# is a control signal from the Intel 855 chipset family chipset used to reduce power on the Intel(R) Pentium(R) M data bus input buffers. DRDY# (Data Ready) is asserted by the data driver on each data transfer, indicating valid data on the data bus. In a multi-common clock data transfer, DRDY# may be deasserted to insert idle clocks.

Table 4-5. Signal Description (Sheet 4 of 7)
Name FERR#/PBE# Type Output Description FERR# (Floating-point Error)PBE#(Pending Break Event) is a multiplexed signal and its meaning is qualified with STPCLK#. When STPCLK# is not asserted, FERR#/PBE# indicates a floating point when the processor detects an unmasked floating-point error. FERR# is similar to the ERROR# signal on the Intel 387 coprocessor, and is included for compatibility with systems using MSDOS*-type floating-point error reporting. When STPCLK# is asserted, an assertion of FERR#/PBE# indicates that the processor has a pending break event waiting for service. The assertion of FERR#/PBE# indicates that the processor should be returned to the Normal state. When FERR#/PBE# is asserted, indicating a break event, it will remain asserted until STPCLK# is deasserted. Assertion of PREQ# when STPCLK# is active will also cause an FERR# break event. For additional information on the pending break event functionality, including identification of support of the feature and enable/disable information, refer to Volume 3 of the Intel (R) Architecture Software Developer's Manual and the Intel (R) Processor Identification and CPUID Instruction application note. For termination requirements please refer to the platform design guides. GTLREF determines the signal reference level for AGTL+ input pins. GTLREF should be set at 2/3 VCCP. GTLREF is used by the AGTL+ receivers to determine if a signal is a logical 0 or logical 1. Please refer to the platform design guides for details on GTLREF implementation. HIT# (Snoop Hit) and HITM# (Hit Modified) convey transaction snoop operation results. Either 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.

HIT# HITM#
Input/ Output Input/ Output
IERR#
Output
IERR# (Internal Error) is asserted by a processor as the result of an internal error. Assertion of IERR# is usually accompanied by a SHUTDOWN transaction on the FSB. This transaction may optionally be converted to an external error signal (e.g., NMI) by system core logic. The processor will keep IERR# asserted until the assertion of RESET#, BINIT#, or INIT#. For termination requirements please refer to the platform design guides. IGNNE# (Ignore Numeric Error) is asserted to force the processor to ignore a numeric error and continue to execute noncontrol floating-point instructions. If IGNNE# is deasserted, the processor generates an exception on a noncontrol floating-point instruction if a previous floating-point instruction caused an error. IGNNE# has no effect when the NE bit in control register 0 (CR0) is set. IGNNE# is an asynchronous signal. However, to ensure recognition of this signal following an Input/Output write instruction, it must be valid along with the TRDY# assertion of the corresponding Input/Output Write bus transaction. 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. INIT# is an asynchronous signal. However, to ensure recognition of this signal following an Input/Output Write instruction, it must be valid along with the TRDY# assertion of the corresponding Input/Output Write bus transaction. INIT# must connect the appropriate pins of both FSB agents. If INIT# is sampled active on the active to inactive transition of RESET#, then the processor executes its Built-in Self-Test (BIST) For termination requirements please refer to the platform design guides. 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.

Table 4-5. Signal Description (Sheet 5 of 7)
Name LINT[1:0] Type Input Description LINT[1:0] (Local APIC Interrupt) must connect the appropriate pins of all APIC Bus agents. When the APIC is disabled, the LINT0 signal becomes INTR, a maskable interrupt request signal, and LINT1 becomes NMI, a nonmaskable interrupt. INTR and NMI are backward compatible with the signals of those names on the Intel Pentium processor. Both signals are asynchronous. Both of these signals must be software configured via BIOS programming of the APIC register space to be used either as NMI/INTR or LINT[1:0]. Because the APIC is enabled by default after reset, operation of these pins as LINT[1:0] is the default configuration. LOCK# indicates to the system that a transaction must occur atomically. This signal must connect the appropriate pins of both 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. When the priority agent asserts BPRI# to arbitrate for ownership of the FSB, it will wait until it observes LOCK# deasserted. This enables symmetric agents to retain ownership of the FSB throughout the bus locked operation and ensure the atomicity of lock. Probe Ready signal used by debug tools to determine processor debug readiness. Please refer to the platform design guides for more implementation details. Probe Request signal used by debug tools to request debug operation of the processor. Please refer to the platform design guides for more implementation details. PROCHOT# (Processor Hot) will go active when the processor temperature monitoring sensor detects that the processor has reached its maximum safe operating temperature. This indicates that the processor Thermal Control Circuit has been activated, if enabled. See Chapter 5 for more details. For termination requirements please refer to the platform design guides. This signal may require voltage translation on the motherboard. Please refer to the platform design guides for more details. Processor Power Status Indicator signal. This signal is asserted when the processor is in a lower state (Deep Sleep and Deeper Sleep). See Section 2.1.6 for more details. 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. The signal must then transition monotonically to a high state. The PWRGOOD signal must be supplied to the processor; it is used to protect internal circuits against voltage sequencing issues. It should be driven high throughout boundary scan operation. For termination requirements please refer to the platform design guides. REQ[4:0]# (Request Command) must connect the appropriate pins of both FSB agents. They are asserted by the current bus owner to define the currently active transaction type. These signals are source synchronous to ADSTB[0]#.

Name RESET# Type Input Description Asserting the RESET# signal resets the processor to a known state and invalidates its internal caches without writing back any of their contents. For a power-on Reset, RESET# must stay active for at least two milliseconds after VCC and BCLK have reached their proper specifications. On observing active RESET#, both FSB agents will deassert their outputs within two clocks. All processor straps must be valid within the specified setup time before RESET# is deasserted. Please refer to the Platform Design Guides for termination requirements and implementation details. There is a 55 ohm (nominal) on die pullup resistor on this signal. 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 of both FSB agents. These pins are RESERVED and must be left unconnected on the board. However, it is recommended that routing channels to these pins on the board be kept open for possible future use. Please refer to the platform design guides for more details. SLP# (Sleep), when asserted in Stop-Grant state, causes the processor to enter the Sleep state. During 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. The processor will recognize only assertion of the RESET# signal, deassertion of SLP#, and removal of the BCLK input while in Sleep state. If SLP# is deasserted, the processor exits Sleep state and returns to Stop-Grant state, restarting its internal clock signals to the bus and processor core units. If DPSLP# is asserted while in the Sleep state, the processor will exit the Sleep state and transition to the Deep Sleep state. SMI# (System Management Interrupt) is asserted asynchronously by system logic. On accepting a System Management Interrupt, the processor saves the current state and enter System Management mode (SMM). An SMI Acknowledge transaction is issued, and the processor begins program execution from the SMM handler. If SMI# is asserted during the deassertion of RESET# the processor will tristate its outputs. 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. When STPCLK# is deasserted, the processor restarts its internal clock to all units and resumes execution. The assertion of STPCLK# has no effect on the bus clock; STPCLK# is an asynchronous input. TCK (Test Clock) provides the clock input for the processor test bus (also known as the Test Access Port). Please refer to the platform design guides for termination requirements and implementation details. TDI (Test Data In) transfers serial test data into the processor. TDI provides the serial input needed for JTAG specification support. Please refer to the platform design guides for termination requirements and implementation details. TDO (Test Data Out) transfers serial test data out of the processor. TDO provides the serial output needed for JTAG specification support. Please refer to the platform design guides for termination requirements and implementation details.

The voltage supply for these pins 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 pins becomes valid. The VID pins are needed to support the processor voltage specification variations. See Table 3-1 for definitions of these pins. The VR must supply the voltage that is requested by the pins, or disable itself. VSSSENSE is an isolated low impedance connection to processor core VSS.

Thermal Specifications and Design Considerations
The Intel Pentium M processor requires a thermal solution to maintain temperatures within operating limits as set forth in Section 5.1. Any attempt to operate that processor outside these operating limits may result in permanent damage to the processor and potentially other components in the system. As processor technology changes, thermal management becomes increasingly crucial when building computer systems. Maintaining the proper thermal environment is key to reliable, long-term system operation. A complete thermal solution includes both component and system level thermal management features. Component level thermal solutions include active or passive heatsinks or heat exchangers attached to the processor exposed die. The solution should make firm contact to the die while maintaining processor mechanical specifications such as pressure. A typical system level thermal solution may consist of a processor fan ducted to a heat exchanger that is thermally coupled to the processor via a heat pipe or direct die attachment. A secondary fan or air from the processor fan may also be used to cool other platform components or lower the internal ambient temperature within the system. To allow for the optimal operation and long-term reliability of Intel processor-based systems, the system/processor thermal solution should be designed such that the processor must remain within the minimum and maximum junction temperature (Tj) specifications at the corresponding thermal design power (TDP) value listed in Table 5-1. Thermal solutions not design to provide this level of thermal capability may affect the long-term reliability of the processor and system. The maximum junction temperature is defined by an activation of the processor Intel Thermal Monitor. Refer to Section 5.1.3 for more details. Analysis indicates that real applications are unlikely to cause the processor to consume the theoretical maximum power dissipation for sustained time periods. Intel recommends that complete thermal solution designs target the TDP indicated in Table 5-1. The Intel Thermal Monitor feature is designed to help protect the processor in the unlikely event that an application exceeds the TDP recommendation for a sustained period of time. For more details on the usage of this feature, refer to Section 5.1.3. In all cases the Intel Thermal Monitor feature must be enabled for the processor to remain within specification.

NOTES: 1. The Thermal Design Power (TDP) specification should be used to design the processor thermal solution. The TDP is not the maximum theoretical power the processor can dissipate. 2.

As measured by the on-die Intel Thermal Monitor. The Intel Thermal Monitor's automatic mode is used to indicate that the maximum TJ has been reached. Refer to Section 5.1 for more details. 4.

Thermal Specifications
Thermal Diode
The Intel Pentium M processor incorporates two methods of monitoring die temperature, the Intel Thermal Monitor and the thermal diode. The Intel Thermal Monitor (detailed in Section 5.1) must be used to determine when the maximum specified processor junction temperature has been reached. The second method, the thermal diode, can be read by an off-die analog/digital converter (a thermal sensor) located on the motherboard, or a stand-alone measurement kit. The thermal diode may be used to monitor the die temperature of the processor for thermal management or instrumentation purposes but cannot be used to indicate that the maximum TJ of the processor has been reached. When using the thermal diode, a temperature offset value must be read from a processor Model Specific register (MSR) and applied. See Section 5.1.2 for more details. Please see Section 5.1.3 for thermal diode usage recommendation when the PROCHOT# signal is not asserted. Table 5-2 and Table 5-3 provide the diode interface and specifications.

Thermal Specifications and Design Considerations
Note:
The reading of the external thermal sensor (on the motherboard) connected to the processor thermal diode signals, will not necessarily reflect the temperature of the hottest location on the die. This is due to inaccuracies in the external thermal sensor, on-die temperature gradients between the location of the thermal diode and the hottest location on the die, and time based variations in the die temperature measurement. Time based variations can occur when the sampling rate of the thermal diode (by the thermal sensor) is slower than the rate at which the TJ temperature can change. Offset between the thermal diode based temperature reading and the Intel Thermal Monitor reading may be characterized using the Intel Thermal Monitor's Automatic mode activation of thermal control circuit. This temperature offset must be taken into account when using the processor thermal diode to implement power management events.
5.1.2
Thermal Diode Offset
A temperature offset value (specified as Toffset in Table 5-3) will be programmed into a Intel Pentium M processor Model Specific Register (MSR). This offset is determined by using a thermal diode ideality factor mean value of n = 1.0022 (shown in Table 5-3) as a reference. This offset must be applied to the junction temperature read by the thermal diode. Any temperature adjustments due to differences between the reference ideality value of 1.0022 and the default ideality values programmed into the on-board thermal sensors, will have to be made before the above offset is applied.

5. The series resistance, RT, is provided to allow for a more accurate measurement of the diode junction temperature. RT as defined includes the pins of the processor but does not include any socket resistance or board trace resistance between the socket and the external remote diode thermal sensor. RT can be used by remote diode thermal sensors with automatic series resistance cancellation to calibrate out this error term. Another application is that a temperature offset can be manually calculated and programmed into an offset register in the remote diode thermal sensors as exemplified by the equation: Terror = [RT*(N-1)*IFWmin]/[(no/q)*ln N 6. Offset value is programmed in processor Model Specific Register.
5.1.3
Intel Thermal Monitor
The Intel Thermal Monitor helps control the processor temperature by activating the TCC when the processor silicon reaches its maximum operating temperature. The temperature at which Intel Thermal Monitor activates the thermal control circuit is not user configurable and is not software visible. Bus traffic is snooped in the normal manner, and interrupt requests are latched (and serviced during the time that the clocks are on) while the TCC is active. With a properly designed and characterized thermal solution, it is anticipated that the TCC would only be activated for very short periods of time when running the most power intensive applications. The processor performance impact due to these brief periods of TCC activation is expected to be so minor that it would not be detectable. 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 may affect the long-term reliability of the processor. In addition, a thermal solution that is significantly under designed may not be capable of cooling the processor even when the TCC is active continuously. The Intel Thermal Monitor controls the processor temperature by modulating (starting and stopping) the processor core clocks or by initiating an Enhanced Intel SpeedStep technology transition when the processor silicon reaches its maximum operating temperature. The Intel Thermal Monitor uses two modes to activate the TCC: Automatic mode and On-Demand mode. If both modes are activated, Automatic mode takes precedence.
Caution:
The Intel Thermal Monitor Automatic Mode mst be enabled via BIOS for the processor to be operating within specifications. There are two automatic modes called Intel Thermal Monitor 1 and Intel Thermal Monitor 2. These modes are selected by writing values to the Model Specific registers (MSRs) of the processor. After Automatic mode is enabled, the TCC will activate only when the internal die temperature reaches the maximum allowed value for operation. Likewise, when Intel Thermal Monitor 2 is enabled, and a high temperature situation exists, the processor will perform an Enhanced Intel SpeedStep technology transition to a lower operating point. When the processor temperature drops below the critical level, the processor will make an Enhanced Intel SpeedStep technology transition to the last requested operating point. Intel Thermal Monitor 2 is the recommended mode on the Intel(R) Pentium(R) M processors. If a processor load based Enhanced Intel SpeedStep technology transition (through MSR write) is initiated when an Intel Thermal Monitor 2 period is active, there are two possible results: 1.If the processor load based Enhanced Intel SpeedStep technology transition target frequency is higher than the Intel Thermal Monitor 2 transition based target frequency, the processor loadbased transition will be deferred until the Intel Thermal Monitor 2 event has been completed.

Thermal Specifications and Design Considerations
2.If the processor load-based Enhanced Intel SpeedStep technology transition target frequency is lower than the Intel Thermal Monitor 2 transition based target frequency, the processor will transition to the processor load-based Enhanced Intel SpeedStep technology target frequency point. When Intel Thermal Monitor 1 is enabled, and a high temperature situation exists, the clocks will be modulated by alternately turning the clocks off and on at a 50% duty cycle. Cycle times are processor speed dependent and will decrease linearly as processor core frequencies increase. Once the temperature has returned to a non-critical level, modulation ceases and TCC goes inactive. A small amount of hysteresis has been included to prevent rapid active/inactive transitions of the TCC when the processor temperature is near the trip point. The duty cycle is factory configured and cannot be modified. Also, automatic mode does not require any additional hardware, software drivers, or interrupt handling routines. Processor performance will be decreased by the same amount as the duty cycle when the TCC is active, however, with a properly designed and characterized thermal solution the TCC most likely will never be activated, or only will be activated briefly during the most power intensive applications. The TCC may also be activated via On-Demand mode. If bit 4 of the ACPI Intel Thermal Monitor Control Register is written to a 1, the TCC will be activated immediately, independent of the processor temperature. When using On-Demand mode to activate the TCC, the duty cycle of the clock modulation is programmable via bits 3:1 of the same ACPI Intel Thermal Monitor Control Register. In automatic mode, the duty cycle is fixed at 50% on, 50% off, however in On-Demand mode, the duty cycle can be programmed from 12.5% on/ 87.5% off, to 87.5% on/12.5% off in 12.5% increments. On-Demand mode may be used at the same time Automatic mode is enabled, however, if the system tries to enable the TCC via On-Demand mode at the same time automatic mode is enabled and a high temperature condition exists, automatic mode will take precedence. An external signal, PROCHOT# (processor hot) is asserted when the processor detects that its temperature is above the thermal trip point. Bus snooping and interrupt latching are also active while the TCC is active. Besides the thermal sensor and thermal control circuit, the Intel Thermal Monitor feature also includes one ACPI register, one performance counter register, three model specific registers (MSR), and one I/O pin (PROCHOT#). All are available to monitor and control the state of the Intel Thermal Monitor feature. The Intel Thermal Monitor can be configured to generate an interrupt upon the assertion or deassertion of PROCHOT#.
Note:
PROCHOT# will not be asserted when the processor is in the Stop Grant, Sleep, Deep Sleep, and Deeper Sleep low power states (internal clocks stopped), hence the thermal diode reading must be used as a safeguard to maintain the processor junction temperature within the 100 C (maximum) specification. If the platform thermal solution is not able to maintain the processor junction temperature within the maximum specification, the system must initiate an orderly shutdown to prevent damage. If the processor enters one of the above low power states with PROCHOT# already asserted, PROCHOT# will remain asserted until the processor exits the Low Power state and the processor junction temperature drops below the thermal trip point. If automatic mode is disabled, the processor will be operating out of specification. Regardless of enabling the automatic or On-Demand modes, in the event of a catastrophic cooling failure, the processor will automatically shut down when the silicon has reached a temperature of approximately 125 C. At this point the FSB signal THERMTRIP# will go active. THERMTRIP# activation is independent of processor activity and does not generate any bus cycles. When THERMTRIP# is asserted, the processor core voltage must be shut down within the time specified in Chapter 3.
