datasheet 7 introduction 1 introduction the intel ? pentium ? m processor based on 90 nm pro cess technology featuring 2-mb l2 cache and 400-mhz front side bus (fsb) is the next generation high- performance, low-power mobile processor based on the intel ? pentium ? processor architecture. throughout this document, intel pentium m proce ssor based on 90 nm technology featuring 2-mb l2 cache and 400 mhz fsb will be referred to as pentium m processor, or simply the processor, including low voltage and ultra low voltage processors. this document contains specifications for the pentium m processors 765/ 755/ 745/ 735/ 725/ 715 standard voltage, 778/758/738 low voltage and 773/753/733j/733/723 ultra low voltage . intel processor numbers are not a measure of performance. processor numbers differentiate features within each pro cessor family, not across different processor fam ilies. see www.intel.com/ products/processor_number for details. the following list provides some of the key features on this processor: ? supports intel ? architecture with dynamic execution ? on-die, primary 32-kb instruction cache and 32-kb write-back data cache ? on-die, 2 mb second level cache with advanced transfer cache architecture ? way set associativity and ecc (error correcting code) support ? data prefetch logic ? streaming simd extensions 2 (sse2) ? 400 mhz, source-synchronous fsb ? advanced power management features including enhanced intel speedstep ? technology ? micro-fcpga and micro-fcbg a packaging technologies ? manufactured on intel?s advanced 90 nanometer process technology with copper interconnect. ? support for mmx? technology and intern et streaming simd instructions ? the processor?s data prefetch logic fetches da ta to the l2 cache before l1 cache requests occurs, resulting in reduced bus cycle penalties and improved performance ? micro-fcpga and micro-fcbga packaging technologies, including lead free sli (second level interconnect) technology for the micro-fcbg a package (for pentium m processors 755, 745, 778, 758, 738, 773, 753, 733j/733, 723) ? execute disable bit support fo r enhanced security (available on processors with cpu signature = 06d8h and recommended for implementation on intel ? 915 express chipset family-based platforms only) the pentium m processor will be manufactured on intel?s advanced 90 nm process technology with copper interconnect. the processor maintains support for mmx technology and internet streaming simd instructions and full compatibility with ia-32 software. the on-die, 32-kb level 1 instruction and data cach es along with the 2-mb l2 cach e with advanced transfer cache
8 datasheet introduction architecture enable signi ficant performance improvement over existing mobile processors. the processor?s data prefetch logic fetches data to the l2 cache before l1 cache requests occurs, resulting in reduced bus cycle penalties and improved performance. the streaming simd extensions 2 (sse2) enab le break-through levels of performance in multimedia applications includ ing 3-d graphics, vide o decoding/encoding, an d speech recognition. the new packed double-precision floating-point inst ructions enhance perfor mance for applications that require greater range and precision, includi ng scientific and engineering applications and advanced 3-d geometry tec hniques, such as ray tracing. the pentium m processor?s 400-mhz fsb utilizes a sp lit-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 speedst ep technology, which enables real-time dynamic switching between multiple voltage and frequency points. this results in optimal performance without compromising low power. th e processor features the auto halt, stop grant, deep sleep, and deeper sleep low power states. the pentium m processor utilizes socketable micro flip-chip pin grid array (micro-fcpga) and surface mount micro flip-chip ba ll grid array (micro-fcbga) p ackage technology. the micro- fcpga package plugs into a 479- hole, surface-mount, zero inserti on force (zif) socket, which is referred to as the mpga479m socket. pentium m processors with cpu signature = 06 d8h 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 feat ure can prevent some cla sses of viruses or worms that exploit buffer overrun vulnerabilities and can thus help improve the overall security of the system. see the intel ? architecture software developer's manual for more detailed information. intel will validate this feature only on inte l 915 express chipset family based platforms and recommends customers implement bios changes relate d to this feature, only on intel 915 express chipset family based platforms. note: the term agtl+ is used to refer to assisted gtl+ signalling technology on some intel processors.
datasheet 9 introduction 1.1 terminology 1.2 references material and concepts available in the following documents may be beneficial when reading this document. please note that ?platform design guides,? when used throughout this document, refers to the platform design guides listed below: 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 th e 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. front side bus (fsb) refers to the interface between the processor and system core logic (also known as the chipset components). table 1-1. references (sheet 1 of 2) document document number/ location 1 intel ? pentium ? m processor on 90 nm process with 2-mb l2 cache - specification update http://www.intel.com/ design/mobile/specupdt/ 302209.htm mobile intel ? 915pm/gm/gms and 910gml express chipset datasheet http://www.intel.com/ design/mobile/datashts/ 305264.htm mobile intel ? 915pm/gm/gms and 910gml expr ess chipset specification update http://www.intel.com/ design/mobile/specupdt/ 307167.htm intel ? 855pm chipset platform design guide: for use with intel ? pentium ? m and intel ? celeron ? processors http://developer.intel.com/ design/mobile/desguide/ 252614.htm intel ? 855pm chipset memory controller hub (mch) datasheet http://developer.intel.com/ design/chipsets/datashts/ 252613.htm intel ? 855pm chipset mch ddr 333/200/266 mhz specification update http://developer.intel.com/ design/chipsets/specupdt/ 253488.htm intel ? 855gm/gme chipset graphics and me mory controller hub (gmch) datasheet http://developer.intel.com/ design/chipsets/datashts/ 252615.htm intel ? 855gm/gme chipset graphics and me mory controller hub (gmch) chipset specification update http://developer.intel.com/ design/chipsets/specupdt/ 253572.htm intel ? 855gm/855gme chipset platform design guide http://developer.intel.com/ design/mobile/desguide/ 252616.htm

datasheet 11 low power features 2 low power features 2.1 clock control and low power states the 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. 2.1.1 normal state this is the normal operatin g state for the processor. 2.1.2 autohalt power-down state autohalt power-down is a low-power state en tered when the processor executes the halt instruction. the processor will transition to th e normal state upon the occurrence of smi#, init#, lint[1:0] (nmi, intr), or fsb interrupt mess age. reset# will cau se 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 ia-32 intel ? architecture software developer's manual, volume 3: system programmer's guide for more information. figure 2-1. clock control states snoop occurs stop grant normal sleep halt/ grant snoop auto halt deep sleep stpclk# asserted slp# asserted slp# deasserted stpclk# deasserted snoop serviced hlt instruction snoop serviced snoop occurs dpslp# de-asserted dpslp# asserted stpclk# asserted stpclk# deasserted halt break v0001-04 core voltage raised core voltage lowered halt break - a20m#, init#, intr, nmi, preq#, reset#, smi#, or apic interrupt deeper sleep
12 datasheet low power features the system can generate a stpclk# while the pro cessor is in the autohalt power-down state. when the system deasserts the stpclk# interrup t, 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 pro cessor is entered 20 bus clocks after the response phase of the processor-issu ed 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 v ccp ) 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 st ate, stpclk# should be deasserted ten or more bus clocks after the de-assertion of slp#. a transition to the halt/grant sn oop state will occur when the pr ocessor 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 processo r returns to the normal state. only one occurrence of each event will be recognized upon retu rn 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 st ate. pbe# will be asserted if there is any pending interrupt latched within th e processor. pending interrupts that are blocked by the eflags.if bit being cl ear will still cause assertion of pb e#. 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 tran sactions 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 latc hed, the processor will return to the stop-grant state or autohalt power-down state, as appropriate.
datasheet 13 low power features 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 ente red only from stop-grant state. once in the stop-grant stat e, the processor will en ter the sleep state upon the assertion of the 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 th e stop-grant state is out of specification and may result in unapproved operation. snoop events that occur while in sleep state or du ring 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 excep tion of slp#, dpslp# or reset#) are allowed on the fsb wh ile the processor is in sleep st ate. any transitio n 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 wh ile 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 lowe r 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 po wer state the processor can enter while maintaining context. deep sleep state is entered by asserting the dpslp# pi n 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 simult aneously. the platform clock chip will stop/tristate bclk within 2 bclks +/- a few nanoseconds. ? deep sleep exit - dpslp# and cpu_stp# are de asserted 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 mu st 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 th e processor can be considered to be in the sleep state. once in the sleep state, the slp# pi n 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 wi ll not respond to interrupts or snoop transactions.
14 datasheet low power features 2.1.7 deeper sleep state the deeper sleep state is the lowe st power state the processor can en ter. this state is functionally identical to the deep sleep stat e but at a lower core voltage. the control signals to the voltage regulator to initiate a transition to the deeper sl eep state are provided on the platform. please refer to the platform design guides listed in table 1-1 . 2.2 enhanced intel speedstep ? technology the pentium m processor features enhanced in tel speedstep 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 us ed to toggle between tw o 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 el iminating chipset dependency. ? if the target frequency is higher than the curr ent 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 in ternally to ensure glitch free transitions. ? low transition latency and large number of transitions possible per second. ? processor core (including l2 cach e) 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 prio r to transition and no processor cache flush necessary. ? improved intel ? thermal monitor mode. ? when the on-die thermal sensor indicates th at the die temperature is too high, the processor can automatically perform a transiti on 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 prev ious frequency/voltage point occurs. ? an interrupt is generated for the up and down intel thermal monitor transitions enabling better system level thermal management.
datasheet 15 low power features 2.3 front side bus low power enhancements the 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 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-d ie termination on the processor fs b 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 pentium m processor incorporates the psi# signal that is assert ed when the processor is in a low power (deep sleep or deeper sleep) state. this signal is asserted upo n 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 tr ansitions. it also helps loosen pwrgood monitoring requirements in the deeper sleep state.

datasheet 17 electrical specifications 3 electrical specifications 3.1 power and ground pins for clean, on-chip power distribution, the pentium m processor has a large number of v cc (power) and v ss (ground) inputs. all power pins must be connected to v cc power planes while all v ss pins must be connected to system ground planes. use of multiple power and ground planes is recommended to reduce i*r drop. pl ease refer to the platform design guides for more details. the processor v cc 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 pentium m processor core frequency is a multiple of the bclk[1:0] frequency. in regard s to processor clocking, the pentium m processor uses a differential clocking implementation. 3.2 voltage identification the pentium m processor uses six voltage identification pins, vid[5:0], to support automatic selection of power supply voltages. the vid pins for the 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.
18 datasheet electrical specifications 3.3 catastrophic thermal protection the pentium m processor supports the thermtrip# signal for catastrophi c thermal protection. an external thermal sensor should also be used to protect the processor and the system against excessive temperatures. even with the activa tion of thermtrip#, which halts all processor internal clocks and activity, leak age 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 pro cessor temperature of 125 c (max imum), 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. table 3-1. voltage identification definition vid vid 5 4 3 2 1 0 v cc v 5 4 3 2 1 0 v cc v 0 0 0 0 0 0 1.708 1 0 0 0 0 0 1.196 0 0 0 0 0 1 1.692 1 0 0 0 0 1 1.180 0 0 0 0 1 0 1.676 1 0 0 0 1 0 1.164 0 0 0 0 1 1 1.660 1 0 0 0 1 1 1.148 0 0 0 1 0 0 1.644 1 0 0 1 0 0 1.132 0 0 0 1 0 1 1.628 1 0 0 1 0 1 1.116 0 0 0 1 1 0 1.612 1 0 0 1 1 0 1.100 0 0 0 1 1 1 1.596 1 0 0 1 1 1 1.084 0 0 1 0 0 0 1.580 1 0 1 0 0 0 1.068 0 0 1 0 0 1 1.564 1 0 1 0 0 1 1.052 0 0 1 0 1 0 1.548 1 0 1 0 1 0 1.036 0 0 1 0 1 1 1.532 1 0 1 0 1 1 1.020 0 0 1 1 0 0 1.516 1 0 1 1 0 0 1.004 0 0 1 1 0 1 1.500 1 0 1 1 0 1 0.988 0 0 1 1 1 0 1.484 1 0 1 1 1 0 0.972 0 0 1 1 1 1 1.468 1 0 1 1 1 1 0.956 0 1 0 0 0 0 1.452 1 1 0 0 0 0 0.940 0 1 0 0 0 1 1.436 1 1 0 0 0 1 0.924 0 1 0 0 1 0 1.420 1 1 0 0 1 0 0.908 0 1 0 0 1 1 1.404 1 1 0 0 1 1 0.892 0 1 0 1 0 0 1.388 1 1 0 1 0 0 0.876 0 1 0 1 0 1 1.372 1 1 0 1 0 1 0.860 0 1 0 1 1 0 1.356 1 1 0 1 1 0 0.844 0 1 0 1 1 1 1.340 1 1 0 1 1 1 0.828 0 1 1 0 0 0 1.324 1 1 1 0 0 0 0.812 0 1 1 0 0 1 1.308 1 1 1 0 0 1 0.796 0 1 1 0 1 0 1.292 1 1 1 0 1 0 0.780 0 1 1 0 1 1 1.276 1 1 1 0 1 1 0.764 0 1 1 1 0 0 1.260 1 1 1 1 0 0 0.748 0 1 1 1 0 1 1.244 1 1 1 1 0 1 0.732 0 1 1 1 1 0 1.228 1 1 1 1 1 0 0.716 0 1 1 1 1 1 1.212 1 1 1 1 1 1 0.700
datasheet 19 electrical specifications 3.4 signal terminations and unused pins all rsvd (reserved) pins must remain unconnected. connection of these pins to v cc , v ss , or to any other signal (including each other) can re sult in component malfunction or incompatibility with future 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 inpu ts 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 (v ss ). unused outputs can be left unconnected. for details on signal terminations, pleas e refer to the platform design guides. the test1 and test2 pins must have a stuffing option connection to v ss 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 express chipset family based platforms. these signals must be left unconnected on platforms designed with the intel 855 chipset family. on these platfo rms, fsb clock frequency should be configured on the motherboard. 3.6 fsb signal groups in order to simplify the following discussion, th e 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 r eceiving. 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 s econd 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 st ill present (a20m#, ignne#, et c.) and can become active at any time during the clock cycle. table 3-2 identifies which signal s are common clock, source synchronous, and asynchronous.
20 datasheet electrical specifications 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 im plemented 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 relatio n to bclk[1:0]. however, all of the cmos signals are required to be asserted for at least three bcl ks in order for the processor to recognize them. see section 3.9 for the dc and ac specifications for the cmos signal groups. table 3-2. fsb pin groups signal group type signals 1 agtl+ common clock input synchronous to bclk[1:0] bpri#, defer#, dpwr#, preq#, reset#, rs[2:0]#, trdy# agtl+ common clock i/o synchronous to bclk[1:0] ads#, bnr#, bpm[3:0]#, br0#, dbsy#, drdy#, hit#, hitm#, lock#, prdy# agtl+ source synchronous i/o synchronous to assoc. strobe agtl+ strobes synchronous to bclk[1:0] adstb[1:0]#, dstbp[3:0]#, dstbn[3:0]# cmos input asynchronous a20m#, dpslp#, ignne#, init#, lint0/intr, lint1/ nmi, pwrgood, smi#, slp#, stpclk# open drain output asynchronous ferr#, ierr#, prochot#, thermtrip# cmos output asynchronous psi#, vid[5:0], bsel[1:0] cmos input synchronous to tck tck, tdi, tms, trst# open drain output synchronous to tck tdo fsb clock clock bclk[1:0], itp_clk[1:0] 2 power/other comp[3:0], dbr# 2 , gtlref, rsvd, test2, test1, thermda, thermdc, v cc , v cca [3:0], v cc p, v cc q [1:0], v cc_sense , v ss, v ss_sense signals associated strobe req[4:0]#, a[16:3]# adstb[0]# a[31:17]# adstb[1]# d[15:0]#, dinv0# dstbp0#, dstbn0# d[31:16]#, dinv1# dstbp1#, dstbn1# d[47:32]#, dinv2# dstbp2#, dstbn2# d[63:48]#, dinv3# dstbp3#, dstbn3#

package mechanical specifications and pin information datasheet 73 ferr#/pbe# output 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 ms- dos*-type floating-point error repor ting. when stpclk# is asserted, an assertion of ferr#/pbe# indicates th at the processor has a pending break event waiting for service. the assert ion of ferr#/pbe# indicates that the processor should be returned to the normal state. when ferr#/pbe# is asserted, indicating a break event, it wi ll remain asserted until stpclk# is deasserted. assertion of preq# when stpc lk# 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 ? architecture software developer?s manual and the intel ? processor identification and cpuid instruction application note. for termination requirements please re fer to the platform design guides. gtlref input gtlref determines the signal refe rence level for agtl+ input pins. gtlref should be set at 2/3 v ccp . gtlref is used by the agtl+ receivers to determine if a signal is a logical 0 or logical 1. pl ease refer to the platform design guides for details on gtlref implementation. hit# hitm# input/ output input/ output hit# (snoop hit) and hitm# (hit modifi ed) convey transac tion 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. 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 optional ly 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 re fer to the platform design guides. ignne# input ignne# (ignore numeric error) is a sserted to force the processor to ignore a numeric error and continue to execute non control 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. howeve r, 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# input 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 re set vector configured during power-on configuration. the processor continues to handle snoop requests during init# assertion. init# is an asynchronous si gnal. however, to ensure recognition of this signal following an input/output write instruction, it must be valid along with the trdy# assertion of the correspondi ng 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 re fer to the platform design guides. itp_clk[1:0] 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. table 4-5. signal description (sheet 4 of 7) name type description
package mechanical specifications and pin information 74 datasheet lint[1:0] input lint[1:0] (local apic interrupt) must connect the appropriate pins of all apic bus agents. when the apic is disabl ed, 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 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, operat ion of these pins as lint[1:0] is the default configuration. lock# input/ output 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 assert ed 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# deasse rted. this enables symmetric agents to retain ownership of the fsb throughout the bus locked operation and ensure the atomicity of lock. prdy# output probe ready signal used by debug tools to determine processor debug readiness. please refer to the platform design gui des for more implementation details. preq# input probe request signal used by de bug tools to request debug operation of the processor. please refer to the platform design gui des for more implementation details. prochot# output prochot# (processor hot) wi ll 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 re fer to the platform design guides. this signal may require voltage translat ion on the motherboard. please refer to the platform design guides for more details. psi# output processor power status indicato r 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 input pwrgood (power good) is a proc essor input. the processor requires this signal to be a clean indicati on 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 glit ches, from the time that the power supplies are turned on until they come with in 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 s equencing issues. it s hould be driven high throughout boundary scan operation. for termination requirements please re fer to the platform design guides. req[4:0]# input/ output req[4:0]# (request command) must connec t 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 s ource synchronous to adstb[0]#. reset# input asserting the reset# signal rese ts 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 v cc and bclk have reached their proper specifications. on observing active reset#, both fsb agents will deassert t heir outputs within two clocks. all processor straps must be valid within th e 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. table 4-5. signal description (sheet 5 of 7) name type description
package mechanical specifications and pin information datasheet 75 rs[2:0]# input rs[2:0]# (response status) are driven by the response agent (the agent responsible for completion of the cu rrent transaction), and must connect the appropriate pins of both fsb agents. rsvd reserved/ no connect these pins are reserved and must be left unconnected on the board. however, it is recommended that routi ng 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# input 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 recogni ze snoops or interrupts. the processor will recognize only assertion of t he 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# input 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# input stpclk# (stop clock), when assert ed, 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 pr ocessor continues to snoop bus transactions and service interrupts while in stop-grant state. when stpclk# is deasserted, the processor restarts its in ternal clock to all units and resumes execution. the assertion of stpclk# has no effect on the bus clock; stpclk# is an asynchronous input. tck input tck (test clock) provi des the clock input for the pr ocessor test bus (also known as the test access port). please refer to the platform design guides for termination requirements and implementation details. tdi input 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 output 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. test1, test2 input test1 and test2 must have a stuffing option of separate pull down resistors to v ss . please refer to the platform design guides for more details. thermda other thermal diode anode. thermdc other thermal diode cathode. thermtrip# output the processor protects itself from catastrophic overheating by use of an internal thermal sensor. this sensor is set well above the normal operating temperature to ensure that there are no false trips. the processor will stop all execution when the junction temperature exceeds approxima tely 125 c. this is signalled to the system by the thermtrip# (thermal trip) pin. for termination requirements please re fer to the platform design guides . table 4-5. signal description (sheet 6 of 7) name type description

datasheet 77 thermal specifications a nd design considerations 5 thermal specifications and design considerations the 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 pr ocessor 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 le vel 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 mainta ining processor mechanical speci fications 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 processo r via a heat pipe or direct die attachment. a seco ndary 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 re liability of intel proces sor-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 indi cates 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 a pplication exceeds the tdp recommenda tion for a sustained period of time. for more details on the usag e of this feature, refer to section 5.1.3 . in all cases the intel thermal monitor feature must be enabled for th e processor to remain within specification.

82 datasheet thermal specifications and design considerations 5.1.3 intel ? thermal monitor the intel thermal monitor helps control the proce ssor temperature by activating the tcc when the processor silicon reaches its maximum operating temperature. the temper ature at which intel thermal monitor activates the thermal control circu it 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 cloc ks are on) while the tcc is active. with a properly designed and char acterized 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 processo r 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 act ivation of the tcc in the anti cipated 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 t cc is active continuously. the intel thermal monitor controls the proce ssor 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 oper ating temperature. the intel thermal monitor uses two modes to activate th e tcc: automatic mode and on-demand mode. if both modes are activated, au tomatic 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 therma l 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 enable d, and a high temperatur e situation exists, the processor will perform an enhanced intel speedst ep technology transitio n to a lower operating point. when the processor temper ature drops below the critical le vel, 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 ? pentium ? m processors. if a processor load based enhanced intel speedstep technology transition (through msr write) is initiated when an intel therma l 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 load- based transition will be deferred until the intel thermal monitor 2 event has been completed. 2.if the processor load-based enhanced intel speed step 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 si tuation exists, the clocks will be modulated by alternately turning the clocks of f 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 go es inactive. a small amount of hysteresis has been included to prevent rapid active/inac tive transitions of the tcc when the processor temperatur e is near the trip point. the duty cycle is factory configured
datasheet 83 thermal specifications a nd design considerations and cannot be modified. also, automatic mode doe s 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 ac tive, however, with a properly designed and characterized thermal solution the tcc most likel y 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 immediatel y, independent of the processor temperature. when usin g on-demand mode to activate th e 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 ci rcuit, the intel thermal monitor feature also includes one acpi register, one performance co unter register, three mo del specific registers (msr), and one i/o pin (prochot#). all are avai lable 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 (i nternal 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 assert ed 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 catastrop hic 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 activit y and does not generate any bus cycles. when thermtrip# is asserted, the processor core volta ge must be shut down within the time specified in chapter 3 .
