introduction r mobile intel ? pentium ? iii processor-m datasheet 11 1. introduction using intel?s advanced 0.13-micron process technology with copper interconnect, the mobile intel ? pentium ? iii processor-m offers high-performance and low-power consumption. the mobile intel pentium iii processor-m (hereafter referred to as ?the proc essor?) is based on the same core as existing mobile intel ? pentium ? iii processors. key performance featur es include internet streaming simd instructions, an advanced transfer cache architecture, and a processor system bus speed of 133 mhz. these features are offered in micro-fcpga pa ckages for socketable boards and micro-fcbga packages for surface mount boards. the low voltage mobile intel pentium iii processor-m will support both a 133-mhz and a 100-mhz bus speed. the ultra low voltage mobile intel pentium iii processor-m will support both 133-mhz and 100-mhz (see product features section for specific supported frequencies) bus speed. the low voltage and ultra low voltage mobile processors will be available only in the micro-fcbga package. all of these technologies make outstanding performance possible for mobile pcs in a variety of shapes and sizes. the processor, when used in conjunction with the intel speedstep ? technology applet, supports enhanced intel speedstep technology, which enables real-time dynamic switching of the voltage and frequency between two performance modes based on cpu demand. this occurs by switching the bus ratios, core operating voltage, and core processor speeds without resetting the system. the processor also features a new ultra low power state called deeper sleep. the 512-kb integrated l2 cache based on the advanc ed transfer cache architecture runs at full speed and is designed to help improve performance. it complements the system bus by providing critical data faster and reducing total system power consumption. the processor also features data prefetch logic that speculatively fetches data to the l2 cache , resulting in improved performance. the mobile pentium iii processor-m?s 64-bit wide assisted gunn ing transceiver logic (agtl) system bus provides a glue-less, point-to-point in terface for a memory controller hub. this document covers the electrical, mechanical , and thermal specifications for the following: ? the mobile pentium iii processor-m is offered at the following frequencies and voltages (maximum performance mode/battery optimized mode): 1.333 ghz/800 mhz, 1.266 ghz/800 mhz, 1.200 ghz/800 mhz, 1.133 ghz/733 mhz, 1.066 ghz/733 mhz, and 1.000 ghz/733 mhz at 1.40 v/1.15 v. ? the low voltage mobile intel pentium iii processor-m is offered at the following frequencies and voltages (maximum performance mode/battery optimized mode): 1.00 ghz/533 mhz, 933/533 mhz, 866/533 mhz, 800/533 mhz, 850/500 mhz, and 800a/500 mhz at 1.15 v/1.05 v. ? the ultra low voltage mobile pentium iii processor-m is offered at the following frequency and voltage (maximum performance mode/battery optimized mode): 933/400 mhz, 900/400 mhz, 866/400 mhz, 850/400 mhz, 800/400 mhz at 1.10 v/0.95 v. unless explicitly stated, all refe rences to the mobile pentium iii processor-m in this document also apply to the low voltage and ultra low voltage mobile pentium iii processor-m.

introduction r mobile intel ? pentium ? iii processor-m datasheet 13 1.3 terminology term definition # a ?#? symbol following a signal name indicates that the signal is active low. this means that when the signal is asserted (based on the name of the signal) it is in an electrical low state. otherwise, signals are driven in an electrical high state when they are asserted. in state machine diagrams, a signal name in a condition indicates the condition of that signal being asserted ! indicates the condition of that signal not being asse rted. for example, the condition ?!stpclk# and hs? is equivalent to ?the active low signal stpc lk# is unasserted (i.e., it is at 1.5 v) and the hs condition is true.? l electrical low signal levels h electrical high signal levels 0 logical low. for example, bd[3:0] = ?1010? = ?hlhl? refers to a hexadecimal ?a,? and d[3:0]# = ?1010? = ?lhlh? also refers to a hexadecimal ?a.? 1 logical high. for example, bd[3:0] = ?1010? = ?hlhl? re fers to a hexadecimal ?a,? and d[3:0]# = ?1010? = ?lhlh? also refers to a hexadecimal ?a.? tbd specifications that are yet to be determined and will be updated in future revisions of the document. x don?t care condition 1.4 references ? p6 family of processors hardware developer?s manual (order number 244001-001) ? intel ? architecture optimization reference manual (order number 245127-001) ? intel ? architecture software developer?s manual ? volume i: basic architectur e (order number 245470) ? volume ii: instruction set reference (order number 245471) ? volume iii: system programming guide (order number 245472) ? ck-408 (ck-titan) clock synthesizer/driver specification (contact your intel field sales representative) ? mobile intel ? pentium ? iii processor-m i/o buffer models, ibis format (contact your intel field sales representative) ? intel ? 830 chipset family: 82830 graphics and memory controller hub (gmch-m) datasheet (order number 298338-003) ? intel ? 830 chipset family: intel ? 830 chipset platform design guide (order number 298339- 003) ? intel ? 830 chipset family: intel ? 82801cam i/o controller hub 3 (ich3-m) datasheet (order number 290716-001) ? intel ? mobile voltage positioning -ii (imvp-ii) design guide (contact your intel field sales representative) ? mobile intel ? pentium ? iii processor-m /440mx platform design guide (contact your intel field sales representative) ? intel ? processor identification and the cpuid instruction application note ap-485 (order number 241618-020)
mobile intel pentium iii processor-m features r 14 mobile intel ? pentium ? iii processor-m datasheet 2. mobile intel pentium iii processor-m features 2.1 new features in the mobile pentium iii processor-m 2.1.1 133-mhz psb with agtl signaling the mobile pentium iii processor-m uses assisted gtl (agtl) signaling on the psb interface. the main difference between agtl and gtl+ used on previous intel processors is v cct = 1.25 v for agtl versus 1.5 v for gtl+. the lower voltage swing enables high performance at lower power. the low voltage mobile pentium iii processor-m will support 100-mhz and 133-mhz bus frequencies. the ultra low voltage mobile pentium iii processor-m will support both 100-mhz and 133-mhz bus frequencies (see product features for speci fic supported frequencies). 2.1.2 512-k on-die integrated l2 cache the 512-k, on die, integrated l2 cache on the mobile pentium iii processor-m is double the l2 cache size on the mobile pentium iii processor. the l2 cache runs at the processor core speed and the increased cache size provides superior processing power. 2.1.3 data prefetch logic the mobile pentium iii processor-m features data prefetch logic that speculatively fetches data to the l2 cache before an l1 cache request occurs. this reduces transactions between the cache and system memory reducing or eliminating bus cycle penalties, resulting in improved performance. the processor also includes extensions to memory order and reorder buffers that boost performance. 2.1.4 differential clocking the mobile intel pentium iii processor-m is the first mobile intel processor to support differential clocking. differential clocking requires the use of two complementary clocks: bclk and bclk#. benefits of differential clocking include easier sca ling to lower voltages, reduced emi, and less jitter. all references to bclk in this document apply to bclk# also even if not explicitly stated. the mobile intel pentium iii processor-m will also support single ended clocking. the processor will configure itself for differential or single ended clocking based on the waveforms detected on the bclk and bclk#/clkref signal lines.

mobile intel pentium iii processor-m features r 16 mobile intel ? pentium ? iii processor-m datasheet 2.2.3 auto halt state this is a low-power mode entered by the processo r through the execution of the hlt instruction. a transition to the normal state is made by a halt break event (one of the following signals going active: nmi, intr, binit#, init#, reset#, flush#, or smi#). asserting the stpclk# signal while in the auto halt state will cause the processor to transition to the quick start state. deasserting stpclk# will cause the processor to return to the auto halt state without issuing a new halt bus cycle. the smi# interrupt is recognized in the auto ha lt state. the return from the system management interrupt (smi) handler can be to either the no rmal state or the auto halt state. see the intel ? architecture software developer ?s manual, volume iii: system programmer?s guide for more information. no halt bus cycle is issued when returning to the auto halt state from the system management mode (smm). the flush# signal is serviced in the auto halt stat e. after the on-chip and off-chip caches have been flushed, the processor will return to the auto halt st ate without issuing a halt bus cycle. transitions in the a20m# and preq# signals are recogn ized while in the auto halt state.

mobile intel pentium iii processor-m features r 18 mobile intel ? pentium ? iii processor-m datasheet 2.2.5 halt/grant snoop state the processor will respond to snoop transactions on the system bus while in the auto halt or quick start state. when a snoop trans action is presented on the system bus the processor will enter the halt/grant snoop state. the processor will remain in this state until the snoop has been serviced and the system bus is quiet. after the snoop has been serviced, the processor will return to its previous state. if the halt/grant snoop state is entered fr om the quick start state, then the input signal restrictions of the quick start state still apply in the halt/grant snoop state, except for those signal transitions that are required to perform the snoop. 2.2.6 deep sleep state the deep sleep state is a very low power state the processor can enter while maintaining its context. the deep sleep state is entered by stopping the bclk and bclk# inputs to the processor, or by asserting the dpslp# signal while it is in the quick st art state. note that either one of the methods can be used to enter deep sleep but not both at the same time. when bclk and bclk# are stopped, they must obey the dc levels speci fied in table 30 and table 31. the processor will return to the quick start stat e from the deep sleep state when the bclk and bclk# inputs are restarted or the dpslp# signal is d easserted. due to the pll lock latency, there is a delay of up to 30 sec after the clocks have started before this state transition happens. picclk may be removed in the deep sleep state. picclk should be designed to turn on when bclk and bclk# turn on or dpslp# is deasserted when tr ansitioning out of the deep sleep state. 2.2.7 deeper sleep state the deeper sleep state is the lowest power state the processor can enter while maintaining its context. it is functionally identical to the deep sleep state but at a lower voltage. the processor transitions to the deeper sleep state from the deep sleep when th e voltage regulator lowers the core voltage. the vid signals for the deeper sleep state are supplied to the voltage regulator through control from the i/o controller hub component. for more details on how this is implemented on the mobile intel pentium iii processor-m /intel 830 plat form, please refer to the intel ? 82801cam i/o controller hub 3 (ich3-m) datasheet and contact your intel field sales representative for details on intel mobile voltage positioning ? ii (imvp-ii) implementation. for details on how deeper sleep is implemented on 440mx chipset based systems using the intel sp eedstep technology control logic plus (isscl+) component, please refer to the mobile intel ? pentium ? iii processor-m/440m x platform design guide.

electrical specifications r mobile intel ? pentium ? iii processor-m datasheet 23 3.1.2 test access port (tap) connection the tap interface is an implementation of the i eee 1149.1 (?jtag?) standard. due to the voltage levels supported by the tap interface, intel recommends that the mobile intel pentium iii processor-m and the other 1.5-v jtag specification compliant devices be last in the jtag chain after any devices with 3.3-v or 5.0-v jtag interfaces within the system. a transla tion buffer should be used to reduce the tdo output voltage of the last 3.3/5.0 v device down to the 1.5-v range that the mobile intel pentium iii processor-m can tolerate. multiple copies of tms and trst# must be provided, one for each voltage level. a debug port and connector may be placed at the start and end of the jtag chain containing the processor, with tdi to the first component coming from the debug port and tdo from the last component going to the debug port. there are no requirements for placing the mobile intel pentium iii processor-m in the jtag chain, except for those th at are dictated by voltage requirements of the tap signals. 3.1.3 catastrophic thermal protection the mobile intel pentium iii processor-m does not support catas trophic thermal protection or the thermtrip# signal. an external thermal sensor must be used to protect the processor and the system against excessive temperatures. if the external ther mal sensor detects a processor junction temperature of 101 c (maximum), both the v cc and v cct supplies to the processor must be reduced to at least 50% of the nominal values within 500 ms, and intel recommends turning them off completely within 1 second to prevent damage to the processor. processor temperature mu st be monitored in all states including low power states. 3.1.4 unused signals all signals named nc must be unconnected. unused agtl inputs, outputs and bi-directional signals should be unconnected. unused cmos active low inputs should be connected to 1.5 v and unused active high inputs should be connected to v ss . unused open-drain outputs should be unconnected. when tying any signal to power or ground, a resistor will allow for system testability. for unused signals, intel suggests that 1.5-k ? resistors are used for pull-ups and 1.0-k ? resistors are used for pull- downs. picclk must be driven with a clock that meets sp ecification and the picd[1:0] signals must be pulled up separately to 1.5 v with 150- ? resistors, even if the local apic is not used. if the tap signals are not used then the inputs should be pulled to ground with 1-k ? resistors and tdo should be left unconnected. 3.1.5 signal state in low-power states 3.1.5.1 system bus signals all of the system bus signals have agtl input, outp ut, or input/output drivers. except when servicing snoops, the system bus signals are tri-stated and pulled up by the termination resistors. snoops are not permitted in the deep sleep and deeper sleep states.
electrical specifications r 24 mobile intel ? pentium ? iii processor-m datasheet 3.1.5.2 cmos and open-drain signals the cmos input signals are allowed to be in either th e logic high or low state when the processor is in a low-power state. in the auto ha lt state these signals are allowed to toggle. these input buffers have no internal pull-up or pull-down resistors and system logic can use cmos or open-drain drivers to drive them. the open-drain output signals have open drain drivers and external pull-up resistors are required. one of the two output signals (ierr#) is a catastrophic error indicator an d is tri-stated (and pulled-up) when the processor is functioning normally. the ferr# output can be either tri-stated or driven to v ss when the processor is in a low-power state depending on the condition of the floating-point unit. since this signal is a dc current path when it is driven to v ss , intel recommends that the software clears or masks any floating-point error condition before putting the processor into the deep sleep state. 3.1.5.3 other signals the system bus clocks (bclk, bclk#) must be driven in all of the low-power states except the deep sleep state. the apic clock (p icclk) must be driven whenever bclk and bclk# are driven. otherwise, it is permitted to turn off picclk by holding it at v ss . bclk and bclk# should be obey the dc levels in table 30 (for differential clocking) and table 31 (for single ended clocking). in the auto halt state, the apic bus data signals (picd[1:0]) may toggle due to apic bus messages. these signals are required to be tr i-stated and pulled-up when the processor is in the quick start or deep sleep states. 3.2 power supply requirements 3.2.1 decoupling guidelines the mobile intel pentium iii processor-m micro-fcpga package has twelve 0805idc, 1- f surface mount decoupling capacitors. eight capacitors are on the v cc supply and four capacitors are on v cct. for the micro-fcbga package, there are six 0.68- f capacitors on v cc and two 0.68- f capacitors on v cct . in addition to the package cap acitors, sufficient board level cap acitors are also necessary for power supply decoupling. thes e guidelines are as follows: ? high and mid frequency vcc deco upling ? place twenty-four 0.22- f 0603 capacitors directly under the package on the solder side of the mo therboard using at least two vias per capacitor node. ten 10- f x7 6.3 v 1206-size ceramic capacitors should be placed around the package periphery near the balls. trace lengths to the vias should be designed to minimize inductance. avoid bending traces to minimize esl. ? high and mid frequency vcct decoupling ? place ten 1- f x7r 0603 ceramic capacitors close to the package. via and trace guidelines are the same as above. ? bulk vcc decoupling ? minimum of 1200- f capacitance with equivalent series resistance (esr) less than or equal to 3.5 m ? . ? bulk vcct decoupling ? platform dependent but recommendation for intel 830 chipset family based systems is minimum of 660 f with esr less than or equal to 7 m ? .

processor initialization and configuration r 78 mobile intel ? pentium ? iii processor-m datasheet 7. processor initialization and configuration 7.1 description the mobile intel pentium iii processor-m has some configuration options that are determined by hardware and some that are determ ined by software. the processor samples its hardware configuration at reset on the active-to-inactive transition of reset#. the p6 family of processors developer?s manual describes these configuration options. some of the configuration options for the mobile intel pentium iii processor-m are described in the remainder of this section. 7.1.1 quick start enable quick start enabling is mandatory on the mobile intel pentium iii processor-m by strapping a15# low. when the stpclk# signal is asserted it will enter the quick start state when a15# is sampled active on the reset# signal?s active-to-inactive transition. the quick start state supports snoops from the bus priority device but it does not support symmetric master snoops nor is the latching of interrupts supported. a ?1? in bit position 5 of the power-on configuration register indicates that the quick start state has been enabled. 7.1.2 system bus frequency the current generation mobile intel pentium iii processor-m will only function with a system bus frequency of 133 mhz. the low voltage mobile intel pentium iii processor-m will support both 100- mhz and 133-mhz bus frequencies. the ultra low voltage mobile intel pentium iii processor-m will support both 100-mhz and 133-mhz bus frequenc ies (see product features section for specific supported frequencies). bit positions 18 to 19 of the power-on configurati on register indicates at which speed a processor will run. 7.1.3 apic enable the processor apic must be hardware enabled by pulling the picd[1:0] signals separately up to 1.5 v and supplying an active picclk to the processor. soft ware can be used to disable the apic if it is not being used, after picd[1:0] are sampled high when reset# is deasserted and the processor has started executing instructions. 7.2 clock frequencies and ratios the mobile intel pentium iii processor-m uses a clock design in which the bus clock is multiplied by a ratio to produce the processor?s internal (or ?core? ) clock. the ratio used is programmed into the processor during manufacturing. the bus ratio programmed into the processor is visible in bit positions 22 to 25 and 27 of the power-on configuration register. table 22 shows the 5-bit codes in the power- on configuration register and their corresponding bus ratios.
processor interface r mobile intel ? pentium ? iii processor-m datasheet 79 8. processor interface 8.1 alphabetical signal reference a[35:3]# (i/o ? agtl) the a[35:3]# (address) signals define a 2 36 -byte physical memory addr ess space. when ads# is active, these signals transmit the address of a tr ansaction; when ads# is inactive, these signals transmit transaction information. these signals must be connected to the appropriate pins/balls of both agents on the system bus. the a[35:24]# signals are protected with the ap1# parity signal, and the a[23:3]# signals are protected with the ap0# parity signal. on the active-to-inactive transiti on of reset#, each processor bus ag ent samples a[35:3]# signals to determine its power-on configuration. see p6 family of processors developer?s manual for details. a20m# (i - 1.5 v tolerant) if the a20m# (address-20 mask) input signal is assert ed, the processor masks ph ysical address bit 20 (a20#) before looking up a line in any internal cache and before drivin g a read/write transaction on the bus. asserting a20m# emulates the 8086 processor's address wrap-a round at the 1-mbyte boundary. assertion of a20m# is only supported in real mode. ads# (i/o - agtl) the ads# (address strobe) signal is asserted to in dicate the validity of a transaction address on the a[35:3]# signals. both 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. this signal must be connected to the appropriate pins/balls on both agents on the system bus. aerr# (i/o - agtl) the aerr# (address parity error) signal is observed and driven by both system bus agents, and if used, must be connected to the appropriate pins/balls of both agents on the system bus. aerr# observation is optionally enabled during power-on configuration; if enabled, a valid assertion of aerr# aborts the current transaction. if aerr# observation is disabled during power-on configuration, a central agent may handle an assertion of aerr# as appropriate to the error handling architect ure of the system. ap[1:0]# (i/o - agtl) the ap[1:0]# (address parity) signals are driven by the request initiator along with ads#, a[35:3]#, req[4:0]# and rp#. ap1# covers a[35:24]#. ap0# covers a[23:3]#. a correct parity signal is high if an even number of covered signals is low and low if an odd number of covered signals are low. this allows parity to be high when all the covered signals are high. ap[1:0]# should be connected to the appropriate pins/balls on both agents on the system bus.
processor interface r 80 mobile intel ? pentium ? iii processor-m datasheet bclk, bclk# (i) the bclk and bclk# signals determines the system bus frequency. on systems with differential clocking , both system bus agents must r eceive these signals to drive their outputs and latch their inputs on the bclk rising edge and bclk# falling edge. all external timing parameters are specified with respect to the crossing point of the bclk rising edge and bclk# falling edge. on systems with single ended clocking, both syst em bus agents must receive the bclk signal to drive their outputs and latch their inputs on the bclk rising edge. all external timing parameters are specified with respect to the bclk signal. th e bclk# signal functions as the clkref input. berr# (i/o - agtl) the berr# (bus error) signal is asserted to indicate an unrecoverable error without a bus protocol violation. it may be driven by either system bus agent and must be connected to the appropriate pins/balls of both agents, if used. however, the mobile intel pentium iii processor-ms do not observe assertions of the berr# signal. berr# assertion conditions are defined by the system configuration. configuration options enable the berr# driver as follows: ? enabled or disabled ? asserted optionally for internal errors along with ierr# ? asserted optionally by the request initiator of a bus transaction after it observes an error ? asserted by any bus agent when it observes an error in a bus transaction binit# (i/o - agtl) the binit# (bus initialization) signal may be observ ed and driven by both system bus agents and must be connected to the appropriate pins/balls of bo th agents, if used. if the binit# driver is enabled during the power-on configuration, binit# is a sserted to signal any bus condition that prevents reliable future information. if binit# is enabled during power-on configuration, and binit# is sampled asserted, all bus state machines are reset and any data which was in transit is lost. all agents reset their rotating id for bus arbitration to the state after reset, and internal coun t information is lost. the l1 and l2 caches are not affected. if binit# is disabled during power-on configuration, a central agent may handle an assertion of binit# as appropriate to the machine check architecture (mca) of the system. bnr# (i/o - agtl) the bnr# (block next request) signal is used to a ssert a bus stall by any bus agent that is unable to accept new bus transactions. during a bus stall, the current bus owner cannot issue any new transactions. since multiple agents may need to request a bus sta ll simultaneously, bnr# is a wired-or signal that must be connected to the appropriate pins/balls of both agents on the system bus. in order to avoid
processor interface r mobile intel ? pentium ? iii processor-m datasheet 81 wire-or glitches associated with simultaneous edge tr ansitions driven by multiple drivers, bnr# is activated on specific clock edges and sampled on specific clock edges. bp[3:2]# (i/o - agtl) the bp[3:2]# (breakpoint) signals are the system su pport group breakpoint signals. they are outputs from the processor that indicate the status of breakpoints. bpm[1:0]# (i/o - agtl) the bpm[1:0]# (breakpoint monitor) signals are breakpoint and performance monitor signals. they are outputs from the processor that indicate the status of breakpoints and programmable counters used for monitoring processor performance. bpri# (i - agtl) the bpri# (bus priority request) signal is used to arbitrate for ownership of the system bus. it must be connected to the appropriate pins/balls on both agents on the system bus. observing bpri# active (as asserted by the priority agent) causes the pr ocessor to stop issuing new requests, unless such requests are part of an ongoing locked operation. the priority agent keeps bp ri# asserted until all of its requests are completed and then re leases the bus by deasserting bpri#. breq0# (i/o - agtl) the breq0# (bus request) signal is a processor arbitration bus signal. the processor indicates that it wants ownership of the system bus by asserting the breq0# signal. during power-up configuration, the central agent must assert the breq0# bus signal. the processor samples breq0# on the active-to-inactive transition of reset#. optionally, this signal may be grounded with a 10- ? resistor. bsel[1:0] (o ? 3.3 v tolerant) the bsel[1:0] (select processor system bus speed) signal is us ed to configure the processor for the system bus frequency. the chipset and system clock generator also uses the bsel signals. the vttpwrgd signal informs the processor to output the bsel signals. during power up the bsel signals will be indeterminate for a small period of time. the chipset and clock generator should not sample the bsel signals until the vttpwrgd signal is asserted. the assertion of the vttpwrgd signal indicates that the bsel signals are stable and driven to a final state by the processor. please refer to figure 12 for the timing relations hip between the bsel and vttpwrgd signals. table 46 shows the encoding scheme for bsel[1:0]. the only supported system bus frequency for the mobile intel pentium iii processor-m is 133 mhz. the low voltage mobile intel pentium iii processor-m will support both 100-mhz and 133- mhz bus frequencies. the ultra low voltage mobile intel pentium iii processor-m will support both 100-mhz and 133-mhz bus frequencies (see product features for specific supported frequencies). if another frequency is used then the processor is not guaranteed to function properly.
processor interface r 82 mobile intel ? pentium ? iii processor-m datasheet table 46. bsel[1:0] encoding bsel[1:0] system bus frequency 01 100 mhz 11 133 mhz clkref (analog) the clkref (system bus clock reference) signal provides a reference voltage to define the trip point for the bclk signal on platforms supporting single ended clocking. this signal should be connected to a resistor divider to generate 1.25 v from the 2.5-v supply. a minimum of 1-uf decoupling capacitance is recommended on clkref. on systems with differential clocking, the clkref pin functions as the bclk# input. cmosref (analog) the cmosref (cmos reference voltage) signal provides a dc level reference voltage for the cmos input buffers. cmosref must be generated fro m a stable 1.5-v supply (830 chipset family), 2.5 v (440mx chipset family) and must meet the vcmosref specification. the same 1.5v (830 chipset family) or 2.5 v (440mx chipset family) su pply should be used to power the chipset cmos i/o buffers that drive the cmos signals. the thevenin equivalent impedance of the vcmosref generation circuits must be less than 0.5 k ? /1 k ? (i.e., top resistor 500 ? , bottom resistor 1 k ? ) for 830 chipset family. the thevenin equivalent impedance of the vcmosref generation circuits must be less than 0.75 k ? /0.5 k ? (i.e., top resistor 750 ? , bottom resistor 500 ? ) for intel 440mx chipset family. please refer to the platform design guid elines for other resistor divider recommendations. d[63:0]# (i/o - agtl) the d[63:0]# (data) signals are the data signals. th ese signals provide a 64-bit data path between both system bus agents, and must be connected to the appropriate pins/balls on both agents. the data driver asserts drdy# to indicate a valid data transfer. dbsy# (i/o - agtl) the dbsy# (data bus busy) signal is asserted by the agent responsible for driving data on the system bus to indicate that the data bus is in use. the data bus is released after dbsy# is deasserted. this signal must be connected to the appropriate pi ns/balls on both agents on the system bus. defer# (i - agtl) the defer# (defer) signal is asserted by an ag ent to indicate that the transaction cannot be guaranteed in-order completion. assertion of defer# is normally the responsibility of the addressed memory agent or i/o agent. this signal must be co nnected to the appropriate pins/balls on both agents on the system bus. dep[7:0]# (i/o - agtl) the dep[7:0]# (data bus ecc protection) signals provide optional ecc protection for the data bus. they are driven by the agent responsible for driving d[63:0]#, and must be connected to the appropriate pins/balls on both agents on the system bus if they ar e used. during power-on configuration, dep[7:0]# signals can be enabled for ecc checking or disabled for no checking.
processor interface r mobile intel ? pentium ? iii processor-m datasheet 83 drdy# (i/o - agtl) the drdy# (data ready) signal is asserted by the da ta driver on each data transfer, indicating valid data on the data bus. in a multi-cycle data transfer , drdy# can be deasserted to insert idle clocks. this signal must be connected to the appropriate pins/balls on both agents on the system bus. dpslp# (i - 1.5 v tolerant) the dpslp# (deep sleep) signal, when asserted in th e quick start state, causes the processor to enter the deep sleep state. in order to return to the quick start state bclk, bclk# must be running and the dpslp# pin must be deasserted. edgctrlp (i-analog) the edgctrlp (edge rate control) signal is used to configure the edge rate of the agtl output buffers. connect the signal to v ss with a 110- ? , 1% resistor. ferr# (o - 1.5 v tolerant open-drain) the ferr# (floating-point error) signal is asserted when the processor detects an unmasked floating- point error. ferr# is similar to the error# signal on the intel 387 coprocessor, and it is included for compatibility with systems using dos-ty pe floating-point error reporting. flush# (i - 1.5 v tolerant) when the flush# (flush) input sign al is asserted, the processor write s back all internal cache lines in the modified state and invalidates all internal cache lines. at the completion of a flush operation, the processor issues a flush acknowledge transaction. the processor stops caching any new data while the flush# signal remains asserted. on the active-to-inactive transition of reset# , each processor bus agen t samples flush# to determine its power-on configuration. ghi# (i - 1.25 v) the ghi# signal controls the selection of the operating mode bus ratio in a mobile intel pentium iii processor-m. this signal is latched on exit from the deep sleep state and determines which of two bus ratios is selected for operation. this signal is ignore d when the processor is not in the deep sleep state. this signal has an on-die pull-up to v cct and should be driven with an open-drain driver with no external pull-up. hit# (i/o - agtl), hitm# (i/o - agtl) the hit# (snoop hit) and hitm# (hit modified) signals convey transaction snoop operation results, and must be connected to the appropriate pins/balls on both agents on the system bus. either bus agent can assert both hit# and hitm# together to indi cate that it requires a snoop stall, which can be continued by reasserting hit# and hitm# together.
processor interface r 84 mobile intel ? pentium ? iii processor-m datasheet ierr# (o - 1.5 v tolerant open-drain) the ierr# (internal error) signal is asserted by th e processor as the result of an internal error. assertion of ierr# is usually accompanied by a sh utdown transaction on the system bus. this transaction may optionally be converted to an external error signal (e.g., nmi) by system logic. the processor will keep ierr# asserted until it is handle d in software or with the assertion of reset#, binit, or init#. ignne# (i - 1.5 v tolerant) the ignne# (ignore numeric error) signal is assert ed to force the processor to ignore a numeric error and continue to execute non-control floating-point instructions. if ignne# is deasserted, the processor freezes on a non-control floating-poi nt instruction if a previous inst ruction caused an error. ignne# has no affect when the ne bit in control register 0 (cr0) is set. init# (i - 1.5 v tolerant) the init# (initialization) signal is asserted to reset integer registers inside the processor without affecting the internal (l1 or l2) caches or the floa ting-point registers. the processor 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 input. if init# is sampled active on reset# 's active-to-inactive transition, then the processor executes its built-in self test (bist). intr (i - 1.5 v tolerant) the intr (interrupt) signal indicates that an external interrupt has been generated. intr becomes the lint0 signal when the apic is enabled. the interrupt is maskable using the if bit in the eflags register. if the if bit is set, the processor vectors to the interrupt handler after completing the current instruction execution. upon recognizing the interrupt request, the processor issues a single interrupt acknowledge (inta) bus transaction. intr must remain active until the inta bus transaction to guarantee its recognition. lint[1:0] (i - 1.5 v tolerant) the lint[1:0] (local apic interrupt) signals must be connected to the appropriate pins/balls of all apic bus agents, including the processor and the system logic or i/o apic component. when apic is disabled, the lint0 signal becomes intr, a maskable interrupt request signal, and lint1 becomes nmi, a non-maskable interrupt. intr and nmi are ba ckward compatible with the same signals for the pentium processor. both signals are asynchronous inputs. both of these signals must be software configured by programming the apic register space to be used either as nmi/intr or lint[1:0] in the bios. if the apic is enabled at reset, then lint[1:0] is the default configuration. lock# (i/o - agtl) the lock# (lock) signal indicates to the system that a sequence of transactions must occur atomically. this signal must be co nnected to the appropriate pins/balls on both agents on the system bus. for a locked sequence of transactions, lock # is asserted from the beginning of the first transaction through the end of the last transaction.
processor interface r mobile intel ? pentium ? iii processor-m datasheet 85 when the priority agent asserts bpri# to arbitrat e for bus ownership, it wa its until it observes lock# deasserted. this enables the processor to retain bus ownership throughout the bus locked operation and guarantee the atomicity of lock. nc (no connect) all signals named nc (no connect) must be left unconnected. nctrl (i - analog) the nctrl signal provides the agtl pull down impe dance control. the processor samples this input to determine the n-channel pull-down device strength when it is the driving agent. an external 14 ? (1% tolerance) pull-up resistor to v cct is required for this signal. pl ease refer to platform design guide for implementation details. nmi (i - 1.5 v tolerant) the nmi (non-maskable interrupt) indicates that an external interrupt has been generated. nmi becomes the lint1 signal when the apic is disabl ed. asserting nmi causes an interrupt with an internally supplied vector value of 2. an external interrupt-acknowledge transaction is not generated. if nmi is asserted during the execution of an nmi service routine, it remains pending and is recognized after the iret is executed by the nmi service routin e. at most, one assertion of nmi is held pending. nmi is rising edge sensitive. picclk (i ? 2.0 v tolerant) the picclk (apic clock) signal is an input clock to the processor and system logic or i/o apic that is required for operation of the processor, system l ogic, and i/o apic components on the apic bus. picd[1:0] (i/o - 1.5 v tolerant open-drain) the picd[1:0] (apic data) signals are used for bi -directional serial message passing on the apic bus. they must be connected to the appropriate pi ns/balls of all apic bus agents, including the processor and the system logic or i/o apic components. if the picd0 signal is sampled low on the active-to-inactive transition of the reset# signal, then the apic is hardware disabled. for the mobile intel pentium iii processor-m, the apic is required to be hardware enabled as described in section 7.1.3 pll1, pll2 (analog) the pll1 and pll2 signals provide isolated analog decoupling is requ ired for the internal pll. see section 3.2.2 for a description of the analog decoupling circuit. prdy# (o - agtl) the prdy# (probe ready) signal is a processor output used by debug tools to determine processor debug readiness. preq# (i - 1.5 v tolerant) the preq# (probe request) signal is used by debug tools to request debug operation of the processor.
processor interface r 86 mobile intel ? pentium ? iii processor-m datasheet pwrgood (i ? 1.8 v tolerant) pwrgood (power good) is a 1.8-v tolerant input. th e processor requires this signal to be a clean indication that clocks and the power supplies (v cc , v cct , etc.) are stable and within their specifications. clean implies that the signal will rema in low, (capable of sinking leakage current) and without glitches, from the time that the power supplies are turned on, until they come within specification. the signal will then transitio n monotonically to a high (1.8v) state. figure 12 through figure 14 illustrate the relationship of pwrgood to ot her system signals. pwrgood can be driven inactive at any time, but clocks and power must again be stable before the rising edge of pwrgood. it must also meet the minimum pulse width specified in table 24 (section 3.7) and be followed by a 1 ms reset# pulse. pwrgood may be asserted be fore bclk is active (please refer to table 24, note 5). the pwrgood signal, which must be supplied to the processor, is used to protect internal circuits against voltage sequencing issues. the pwrgood signal should be driven high throughout boundary scan operation. req[4:0]# (i/o - agtl) the req[4:0]# (request command) signals must be connected to the appropriate pins/balls on both agents on the system bus. they are asserted by the current bus owner when it drives a[35:3]# to define the currently active transaction type. reset# (i - agtl) asserting the reset# signal resets the processor to a known state and invalidates the l1 and l2 caches without writing back modified (m state) lines . for a power-on type re set, reset# must stay active for at least 1 ms after v cc and bclk, bclk# have reached their proper dc and ac specifications and after pwrgood has been asserted . when observing active reset#, all bus agents will deassert their outputs within two clocks. reset# is the only agtl signal that does not have on- die agtl termination. a 56.2- ?, 1% terminating resistor connected to v cct is required. a number of bus signals are sampled at the active-to-inactive transition of reset# for the power-on configuration. the configuration options are described in section 4 and in the p6 family of processors developer?s manual . unless its outputs are tri-stated during power-on co nfiguration, after an activ e-to-inactive transition of reset#, the processor optionally executes its built-in self-test (bist) and begins program execution at reset-vector 000ffff0h or fffffff0h. reset# must be connected to the appropriate pins/balls on both agents on the system bus. rp# (i/o - agtl) the rp# (request parity) signal is driven by the request initiator and provides parity protection on ads# and req[4:0]#. rp# should be connected to the appropriate pins/balls on both agents on the system bus. a correct parity signal is high if an even number of covered signals is low and low if an odd number of covered signals are low. this definition allows parity to be high when all covered signals are high.
processor interface r mobile intel ? pentium ? iii processor-m datasheet 87 rs[2:0]# (i/o - agtl) the rs[2:0]# (response status) sign als are driven by the response agent (the agent responsible for completion of the current transaction) and must be connected to the appropriate pins/balls on both agents on the system bus. rsp# (i - agtl) the rsp# (response parity) signal is driven by the response agent (the agent responsible for completion of the current transaction) during asser tion of rs[2:0]#. rsp# provides parity protection for rs[2:0]#. rsp# should be connected to the appropriate pins/balls on both agents on the system bus. a correct parity signal is high if an even number of covered signals are low, and it is low if an odd number of covered signals are low. during idle state of rs[2:0]# (rs[2:0]#=000), rsp# is also high since it is not driven by any ag ent guaranteeing correct parity. rttimpedp (i-analog) the rttimpedp (r tt impedance/pmos) signal is used to configure the on-die agtl termination. connect the rttimpedp signal to v ss with a 56.2- ? , 1% resistor. smi# (i - 1.5 v tolerant) the smi# (system management interrupt) is assert ed asynchronously by sy stem logic. on accepting a system management interrupt, the processor saves the current state and enters system management mode (smm). an smi acknowledge transaction is issued, and the processor begins program execution from the smm handler. stpclk# (i - 1.5 v tolerant) the stpclk# (stop clock) signal, when asserted, causes the processor to enter a low-power quick start state. the processor issues a stop grant ac knowledge special transaction and stops providing internal clock signals to all units except the bus and apic units. the processor continues to snoop bus transactions and service interrupts while in the qu ick start state. when stpclk# is deasserted and other conditions in are met, the processor restarts its internal clock to all units and resumes execution. the assertion of stpclk# has no affect on the bus clock. tck (i - 1.5 v tolerant) the tck (test clock) signal provides the clock input for the test bus (also known as the test access port). tdi (i - 1.5 v tolerant) the tdi (test data in) signal transfers serial test data to the processor. tdi provides the serial input needed for jtag support. tdo (o - 1.5 v tolerant open-drain) the tdo (test data out) signal transfers serial te st data from the processor. tdo provides the serial output needed for jtag support.
processor interface r 88 mobile intel ? pentium ? iii processor-m datasheet testhi[2:1] (i - 1.25 v tolerant) the testhi[2:1] (test input high) signals are used during processor test and need to be pulled high during normal operation. testlo[2:1] (i - 1.5 v tolerant) the testlo[2:1] (test input low) signals are used during processor test and needs to be pulled to ground during normal operation. thermda, thermdc (analog) the thermda (thermal diode anode) and thermd c (thermal diode cathode) signals connect to the anode and cathode of the on-die thermal diode. tms (i - 1.5 v tolerant) the tms (test mode select) signal is a jtag support signal used by debug tools. trdy# (i/o - agtl) the trdy# (target ready) signal is asserted by the targ et to indicate that the target is ready to receive write or implicit write-back data tr ansfer. trdy# must be connected to the appropriate pins/balls on both agents on the system bus. trst# (i - 1.5 v tolerant) the trst# (test reset) signal resets the test a ccess port (tap) logic. the mobile intel pentium iii processor-m does not self-reset during power on; th erefore, it is necessary to drive this signal low during power-on reset. vid[4:0] (o ? open-drain) the vid[4:0] (voltage id) pins/balls can be used to support automatic selection of power supply voltages. please refer to section 3.2.2 for details. vref (analog) the vref (agtl reference voltage) signal provid es a dc level reference voltage for the agtl input buffers. a voltage divider should be used to divide v cct by 2 / 3 . resistor values of 1.00 k ? and 2.00 k ? are recommended. decouple the vref signal with three 0.1- f high-frequency capacitors close to the processor. vttpwrgd (i ? 1.25 v) the vttpwrgd signal informs the processor to output the vid sign als. during power up, the vid signals will be in an indeterminate state for a small period of time. the voltage regulator should not sample and/or latch the vid signals until the vttp wrgd signal is asserted. the assertion of the vttpwrgd signal indicates that the vid signals are stable and are driven to the final state by the processor. please refer to figure 12 for the power up sequence, table 25 for vttpwrgd transition time and section 4.3.1 for vttpwrgd signal quality specifications.

appendix a. pll rlc filter specification r mobile intel ? pentium ? iii processor-m datasheet 91 appendix a. pll rlc filter specification a1. introduction all mobile intel pentium iii processor-ms have intern al pll clock generators, which are analog in nature and require quiet power supplies for minimum jitter. jitter is detrimental to a system; it degrades external i/o timings as well as internal core timings (i.e. maximum frequency). the pll rlc filter specifications for the mobile intel pentium iii processor-m are the sa me as those for the mobile pentium iii processor. the general desired topology is shown in figure 2. excluded from the external circuitry are parasitics a ssociated with each component. a2. filter specification the function of the filter is two fold. it protects the pll from external noise through low-pass attenuation. it also protects the pll from internal noise through high-pass filtering. in general, the low-pass description forms an ade quate description for the filter. the ac low-pass specification, with input at v cct and output measured across the capacitor, is as follows: ? < 0.2-db gain in pass band ? < 0.5-db attenuation in pass band < 1 hz (see dc drop in next set of requirements) ? 34-db attenuation from 1 mhz to 66 mhz ? 28-db attenuation from 66 mhz to core frequency ? the filter specification (ac) is graphically shown in figure 29. other requirements: ? use a shielded type inductor to minimize magnetic pickup ? the filter should support a dc current of at least 30 ma ? the dc voltage drop from v cct to pll1 should be less than 60 mv, which in practice implies series resistance of less than 2 ? . this also means that the pass band (from dc to 1 hz) attenuation below 0.43 db for v cct = 1.25 v.

appendix a. pll rlc filter specification r mobile intel ? pentium ? iii processor-m datasheet 93 table 53. pll filter resistor recommendations resistor part number value tolerance power r1 various 1 ? 10% 1/16 w to satisfy damping requirements, total series resistance in the filter (from v cct to the top plate of the capacitor) must be at least 0.35 ? . this resistor can be in the form of a discrete component, or routing, or both. for example, if the picked inductor has minimum dcr of 0.25 ? , then a routing resistance of at least 0.10 ? is required. be careful not to exceed the maximum resistance rule (2 ? ). for example, if using discrete r1, the maximum dcr of the l should be less than 2.0 - 1.1 = 0.9 ? , which precludes using l2 and possibly l1. other routing requirements include: ? the capacitor should be close to the pll1 and pll2 pins, with less than 0.1 ? per route (these routes do not count towards the minimum damping resistance requirement). ? the pll2 route should be parallel and next to the pll1 route (minimize loop area). ? the inductor should be close to the capacitor; any routing resist ance should be inserted between vcct and the inductor. ? any discrete resistor should be inserted between v cct and the inductor. a4. comments ? a magnetically shielded inductor protects the circuit from picking up external flux noise. this should provide better timing margins than with an unshielded inductor. ? a discrete or routed resistor is required beca use the lc filter by nature has an under-damped response, which can cause resonance at the lc po le. noise amplification at this band, although not in the pll-sensitive spectrum, could cause a fa tal headroom reduction for analog circuitry. the resistor serves to dampen the response. syst ems with tight space constraints should consider a discrete resistor to provide the required damping resistance. too large of a damping resistance can cause a large ir drop, which means le ss analog headroom and lower frequency. ? ceramic capacitors have very high self-resonance frequencies, but they are not available in large capacitance values. a high self-resonant frequency coupled with low esl/esr is crucial for sufficient rejection in the pll and high frequency band. the recommended tantalum capacitors have acceptably low esr and esl. ? the capacitor must be close to the pll1 and pll2 pins; otherwise the value of the low esr tantalum capacitor is wasted. note the distance constraint should be translated from the 0.1- ? requirement.
