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 processor”) is based on the same core as existing
Mobile Intel® Pentium® III Processors. Key performance features 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 packages 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 Advanced 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 Gunning Transceiver Logic (AGTL) system bus
provides a glue-less, point-to-point interface 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,

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 asserted. For example, the condition “!STPCLK# and HS” is
equivalent to “the active low signal STPCLK# is unasserted (i.e., it is at 1.5 V) and the HS condition is true.”

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 VCCT = 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 specific supported frequencies).
2.1.2
2.1.3
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.
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 scaling 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.

functionally identical to the Deep Sleep State but at a lower voltage. More details are provided in
Section 2.2.7.

Power Management
2.2.1
Clock Control Architecture
The Mobile Pentium III Processor-M clock control architecture (Figure 1) has been optimized for
leading edge mobile computer designs. The clock control architecture consists of six different clock
states: Normal, Auto Halt, Quick Start, HALT/Grant Snoop, Deep Sleep, and Deeper Sleep states. The
Auto Halt state provides a low-power clock state that can be controlled through the software execution
of the HLT instruction. The Quick Start state provides a very low power and low exit latency clock
state that can be used for hardware controlled “idle” computer states. The Deep Sleep and Deeper
Sleep states provide extremely low-power states that can be used for “Power-On-Suspend” computer
states, which is an alternative to shutting off the processor’s power. The exit latency of the Deep Sleep
state is 30 µsec in the Mobile Pentium III Processor-M. Performing state transitions not shown in
Figure 1 is neither recommended nor supported. Table 2 provides the clock state characteristics, which
are described in detail in the following sections.
2.2.2
Normal State
The Normal state of the processor is the normal operating mode where the processor’s core clock is
running and the processor is actively executing instructions.
Mobile Intel® Pentium ® III Processor-M Datasheet
15
Mobile Intel Pentium III Processor-M Features
R
2.2.3
Auto Halt State
This is a low-power mode entered by the processor 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 Halt state. The return from the System Management
Interrupt (SMI) handler can be to either the Normal 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 state. After the on-chip and off-chip caches have been
flushed, the processor will return to the Auto Halt state without issuing a Halt bus cycle. Transitions in
the A20M# and PREQ# signals are recognized while in the Auto Halt state.

HLT – HLT instruction executed

2. Restrictions apply to the use of both methods of entering Deep Sleep. See Deep Sleep state description for details.
2.2.4
Quick Start State
The processor is required to be configured for the Quick Start state by strapping the A15# signal low.
More details are provided in Section 7.1. In the Quick Start state the processor is only capable of acting
on snoop transactions generated by the system bus priority device. Because of its snooping behavior,
Quick Start can only be used in a uniprocessor (UP) configuration.
A transition to the Deep Sleep state can be made by stopping the clock input to the processor or
asserting the DPSLP# signal. A transition back to the Normal state (from the Quick Start state) is made
only if the STPCLK# signal is deasserted.
While in the Quick Start state the processor is limited in its ability to respond to input. It is incapable
of latching any interrupts, servicing snoop transactions from symmetric bus masters or responding to
FLUSH# or BINIT# assertions. While the processor is in the Quick Start state, it will not respond
properly to any input signal other than STPCLK#, RESET#, or BPRI#. If any other input signal
changes, then the behavior of the processor will be unpredictable. No serial interrupt messages may
begin or be in progress while the processor is in the Quick Start state.
RESET# assertion will cause the processor to immediately initialize itself, but the processor will stay
in the Quick Start state after initialization until STPCLK# is deasserted.

R
2.2.5
2.2.6
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 transaction 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 from 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.
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 Start 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 specified in Table 30 and Table 31.
The processor will return to the Quick Start state from the Deep Sleep state when the BCLK and
BCLK# inputs are restarted or the DPSLP# signal is deasserted. Due to the PLL lock latency, there is a
delay of up to 30 µsec 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 transitioning 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 the 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 platform, 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 SpeedStep technology Control Logic Plus (ISSCL+)
component, please refer to the Mobile Intel® Pentium® III Processor-M/440MX Platform Design

Operating System Implications of Low-power States
The time-stamp counter and the performance monitor counters are not guaranteed to count in the
Quick Start state. The local APIC timer and performance monitor counter interrupts should be disabled
before entering the Deep Sleep state or the resulting behavior will be unpredictable.
Enhanced Intel SpeedStep Technology
The Mobile Intel Pentium III Processor-M supports Enhanced Intel SpeedStep technology. Enhanced
Intel SpeedStep technology allows the processor to switch automatically between two core frequencies
based on CPU demand, without resetting the processor or changing the system bus frequency. The
processor has two bus ratios programmed into it instead of one, and the GHI# signal controls which
one is used. After reset, the processor will start in the lower of its two core frequencies, the Battery
Optimized mode. An operating mode transition to the high core frequency can be made by putting the
processor into the Deep Sleep state, raising the core voltage, setting GHI# low, and returning to the
Normal state. This puts the processor into the “Maximum performance” mode. Reversing these steps
transitions the processor back to the low-core frequency. Please contact your Intel Field Sales
Representative for details on how Enhanced Intel SpeedStep technology can be implemented with the
Mobile Intel Pentium III Processor-M, Intel 830MP chipset, or its equivalent and the Intel SpeedStep
technology applet.
2.3
AGTL Signals
The Mobile Pentium III Processor-M system bus signals use a variation of the low-voltage swing GTL
signaling technology. The AGTL system bus depends on incident wave switching and uses flight time
for timing calculations of the AGTL signals, as opposed to capacitive derating. Intel recommends
analog signal simulation of the system bus including trace lengths. Contact your field sales
representative to receive the IBIS models for the Mobile Pentium III Processor-M.
The AGTL system bus of the Mobile Pentium III Processor-M is designed to support high-speed data
transfers with multiple loads on a long bus that behaves like a transmission line. This termination is
provided on the processor core (except for the RESET# signal).

1. The recommendations above are only for signals that are being used. These recommendations are maximum
values only; stronger pull-ups may be used. Pull-ups for the signals driven by the chipset should not violate the
chipset specification. Refer to Section 3.1.4 for the required pull-up or pull-down resistors for signals that are not
being used.
2. Open-drain signals must never violate the undershoot specification in Section 4.3. Use stronger pull-ups if there
is too much undershoot.
3. GHI# has an on-die pull-up to VCCT
.
4. A pull-down on BREQ0# is an alternative to having the central agent to drive BREQ0# low at reset.
5. A 56.2 Ω 1% terminating resistor connected to VCCT is required.
6. The following signals are actively driven high by the ICH3-M component and do not need external pull up
resistors on ICH3-M based platforms: A20M#, DPSLP#, INIT#, IGNNE#, LINT0/INTR, LINT1/NMI, SMI#,
STPCLK#.
7. These pull up recommendations apply to systems on which these signals are not actively pulled high such as
those utilizing the 82443MX chipset.
3.1.1
Power Sequencing Requirements
Unlike the Mobile Pentium III Processor, the Mobile Intel Pentium III Processor-M has specific power
sequencing requirements. The power on sequencing and timings are shown in Figure 12 and Table 25.
Power down timing requirements are shown in Figure 13, Figure 14, and Table 25. The VCC power
plane must not rise too fast. At least 200 µsec (TR) must pass from the time that VCC is at 10% of its
nominal value until the time that VCC is at 90% of its nominal value. The recommended VCC rise and
fall times for Enhanced Intel SpeedStep technology and Deeper Sleep transitions are 100 µsec (max).
For more details, please refer to the Intel® Mobile Voltage Positioning -II (IMVP-II) Design Guide.

Electrical Specifications
R
3.1.2
Test Access Port (TAP) Connection
The TAP interface is an implementation of the IEEE 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 translation 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 that are dictated by voltage requirements of the TAP
signals.
3.1.3
3.1.4
Catastrophic Thermal Protection
The Mobile Intel Pentium III Processor-M does not support catastrophic 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 thermal sensor detects a processor junction temperature
of 101°C (maximum), both the VCC and VCCT 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 must be monitored in all states
including low power states.
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 VSS. 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-kΩ resistors are used for pull-ups and 1.0-kΩ resistors are used for pull-
downs.
PICCLK must be driven with a clock that meets specification and the PICD[1:0] signals must be pulled
up separately to 1.5 V with 150-Ω 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-kΩ 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, output, 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
3.1.5.2
3.1.5.3
CMOS and Open-drain Signals
The CMOS input signals are allowed to be in either the logic high or low state when the processor is in
a low-power state. In the Auto Halt 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 and is tri-stated (and pulled-up)
when the processor is functioning normally. The FERR# output can be either tri-stated or driven to VSS
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 VSS, Intel recommends that the software clears or
masks any floating-point error condition before putting the processor into the Deep Sleep state.
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 (PICCLK) must be driven whenever BCLK and BCLK# are driven.
Otherwise, it is permitted to turn off PICCLK by holding it at VSS. 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 tri-stated and pulled-up when the processor is in the Quick Start or
Deep Sleep states.

Power Supply Requirements
3.2.1
Decoupling Guidelines
The Mobile Intel Pentium III Processor-M Micro-FCPGA package has twelve 0805IDC, 1-µF surface
mount decoupling capacitors. Eight capacitors are on the VCC supply and four capacitors are on VCCT.
For the Micro-FCBGA package, there are six 0.68-µF capacitors on VCC and two 0.68-µF capacitors
on VCCT . In addition to the package capacitors, sufficient board level capacitors are also necessary for
power supply decoupling. These guidelines are as follows:
•
High and Mid Frequency VCC decoupling – Place twenty-four 0.22-µF 0603 capacitors directly
under the package on the solder side of the motherboard using at least two vias per capacitor
node. Ten 10-µF 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-µF X7R 0603 ceramic capacitors close
to the package. Via and trace guidelines are the same as above.
Bulk VCC decoupling – Minimum of 1200-µF capacitance with Equivalent Series Resistance
(ESR) less than or equal to 3.5 mΩ.
Bulk VCCT decoupling – Platform dependent but recommendation for Intel 830 Chipset Family
based systems is minimum of 660 µF with ESR less than or equal to 7 mΩ.

voltage specification variations on current and future processors. VID[4:0] are defined in Table 7. The
voltages specified in the VID table are the Battery Optimized Mode VCC voltages. The VID[4:0]
signals are open drain on the processor and need pullup resistors to 3.3 V on the motherboard. Please
refer to the mobile VR guidelines provided by Intel for additional information.

System Bus Clock and Processor Clocking
The BCLK and BCLK# clock inputs directly control the operating speed of the system bus interface.
All system bus timing parameters are specified with respect to the crossing point of the rising edge of
the BCLK input and falling edge of the BCLK# input. The Mobile Intel Pentium III Processor-M core
frequency is a multiple of the BCLK frequency. The processor core frequency is configured during
manufacturing. The configured bus ratio is visible to software in the Power-on configuration register.
See Section 7.2 for details.
Multiplying the bus clock frequency is necessary to increase performance while allowing for easier
distribution of signals within the system. Clock multiplication within the processor is provided by the
internal Phase Lock Loop (PLL), which requires constant frequency BCLK, BCLK# inputs. During
Reset or on exit from the Deep Sleep state, the PLL requires some amount of time to acquire the phase
of BCLK and BCLK#. This time is called the PLL lock latency, which is specified in Section 3.7, AC
timing parameters T18 and T47.
Enhanced Intel SpeedStep Technology
The Mobile Intel Pentium III Processor-M supports Enhanced Intel SpeedStep technology, which
enables the processor to operate in two modes, the Maximum Performance mode or the Battery
Optimized mode. Each frequency and voltage pair identifies the operating mode. The voltage provided
to the processor must meet the core voltage specification for the current operating mode. If an
operating mode transition is made, then the system logic must direct the voltage regulator to regulate to
the voltage specification of the other mode. After reset, the processor will start in the lower of its two
core frequencies, so the core voltage must meet the lower voltage specification. Any RESET# assertion
will force the processor to the lower frequency, and the core voltage must behave appropriately. INIT#
assertions ("soft" resets) and APIC bus INIT messages do not change the operating mode of the
processor. Some electrical and thermal specifications are for a specific voltage and frequency. The
Mobile Intel Pentium III Processor-M will meet the electrical and thermal specifications specific to the
current operating mode, and it is not guaranteed to meet the electrical and thermal specifications
specific to the opposite operating mode. The timing specifications must be met when performing an
operating mode transition.

Maximum Ratings
Table 8 contains the Mobile Intel Pentium III Processor-M stress ratings. Functional operation at the
absolute maximum and minimum is neither implied nor guaranteed. The processor should not receive a
clock while subjected to these conditions. Functional operating conditions are provided in the AC and
DC tables. Extended exposure to the maximum ratings may affect device reliability. Furthermore,
although the processor contains protective circuitry to resist damage from static electric discharge, one
should always take precautions to avoid high static voltages or electric fields.

DC Specifications
Table 9 through Table 18 list the DC specifications for the Mobile Intel Pentium III Processor-M.
Specifications are valid only while meeting specifications for the junction temperature, clock
frequency, and input voltages. The junction temperature range for all DC specifications is 0°C to
100°C. Care should be taken to read all notes associated with each parameter. Unlike the Mobile
Pentium III Processor, the Vcc tolerances for the Mobile Intel Pentium III Processor-M are not specified
as a percentage of nominal. The tolerances are instead specified in the form of load lines for the static
and transient cases in Table 10 through Table 15. Illustration of the load lines is shown in Figure 4 and
Figure 5.

NOTES:
1. All AC timings for AGTL and CMOS signals are referenced to the BCLK and BCLK# crossing point.
2. Measured on differential waveform: defined as (BCLK - BCLK#).
3. Not 100% tested. Specified by design/characterization.
4. Due to the difficulty of accurately measuring clock jitter in a system, it is recommended that the clock driver be
designed to meet a period stability specification into a test load of 10 to 20 pF. This should be measured on the
rising edge of adjacent BCLKs at the BCLK, BCLK# crossing point. The jitter present must be accounted for as
a component of BCLK skew between devices. Period difference is measured around 0 V crossing points.
5. Measurement taken from common mode waveform, measure rise/fall time from 0.41 to 0.86 V. Rise/fall time
matching is defined as “the instantaneous difference between maximum BCLK rise (fall) and minimum BCLK#
fall (rise) time, or minimum BCLK rise (fall) and maximum BCLK# fall (rise) time ”. This parameter is designed to
guard waveform symmetry.
6. Rise time is measured from -0.35 V to 0.35 V and fall time is measured from 0.35 V to -0.35 V.
7. Measured on common mode waveform - includes every rise/fall crossing.
8. Measured at the package ball for the Micro-FCBGA package.
9. Measured at the socket pin for the Micro-FCPGA package.

1. All AC timings for CMOS and Open-drain signals are referenced to the crossing point of the BCLK rising edge
and BCLK# falling edge for Differential Clocking and to the rising edge of BCLK at 1.25V for Single Ended
Clocking. All CMOS and Open-drain signals are referenced at 1.0 V.
2. Minimum output pulse width on CMOS outputs is 2 BCLKs.
3. This specification only applies when the APIC is enabled and the LINT1 or LINT0 signal is configured as an
edge triggered interrupt with fixed delivery, otherwise specification T14 applies.
4. When driven inactive, or after VCC, VCCT and BCLK, BCLK# become stable. PWRGOOD must remain below
VIL18,MAX until all the voltage planes meet the voltage tolerance specifications in Table 9 through Table 15 and
BCLK, BCLK# have met the BCLK, BCLK# AC specifications in Table 30 and Table 31 for at least 2 µs.
PWRGOOD must rise error-free and monotonically to 1.8 V.
5. If the BCLK Settling Time specification (T60) can be guaranteed at power-on reset then the PWRGOOD
Inactive Pulse Width specification (T15) is waived and BCLK may start after PWRGOOD is asserted.
PWRGOOD must still remain below VIL18,max until all the voltage planes meet the voltage tolerance
specifications.

NOTES:
1. All AC timings for TAP signals are referenced to the TCK rising edge at 1.0 V. All TAP and CMOS signals are
referenced at 1.0 V.
2. Not 100% tested. Specified by design/characterization.
3. 1 ns can be added to the maximum TCK rise and fall times for every 1 MHz below 16 MHz.
4. Referenced to TCK rising edge.
5. Referenced to TCK falling edge.
6. Valid delay timing for this signal is specified into 150 Ω terminated to 1.5 V and 0 pF of external load. For real
system timings these specifications must be derated for external capacitance at 105 ps/pF.
7. Non-Test Outputs and Inputs are the normal output or input signals (except TCK, TRST#, TDI, TDO, and TMS).
These timings correspond to the response of these signals due to boundary scan operations.
8. During Debug Port operation use the normal specified timings rather than the TAP signal timings.

PWRGOOD, VTTPWRGD Signal Quality Specifications
The processor requires PWRGOOD to be a clean indication that clocks and the power supplies (VCC,
V
V
CCT, etc.) are stable and within their specifications. Clean implies that the signal will remain below
IL18 and without errors from the time that the power supplies are turned on, until they come within
specification. The signal will then transition monotonically to a high (1.8 V) state. The VTTPWRGD
signal must also transition monotonically.
The VTTPWRGD signal is an input to the processor used to determine that the VTT power is stable
and the VID and BSEL signals should be driven to their final state by the processor. To ensure the
processor correctly reads this signal, it must meet the requirements shown in Table 36 while the signal
is in its transition region of 300 mV to 900 mV. Also, VTTPWRGD should only enter the transition
region once, after VTT is at nominal values, for the assertion of the signal.
4.3.1.1.1
VTTPWRGD Noise Parameter Specification
Table 36. VTTPWRGD Noise Parameter Specification
Parameter
Specification
Amount of noise (glitch)
Less than 100 mV
In addition, the VTTPWRGD signal should have reasonable transition time through the transition
region. A sharp edge on the signal transition will minimize the chance of noise causing a glitch on this
signal. Intel recommends the following transition time for the VTTPWRGD signal.

VTTPWRGD Transition Parameter Recommendation
Table 37. VTTPWRGD Transition Parameter Recommendation
Parameter
Recommendation
Transition time (300 mV to 900 mV)
Less than or equal to 100 µs
In addition, the VTT_PWRGD signal should have reasonable transition time through the transition
region. A sharp edge on the signal transition will minimize the chance of noise causing a glitch on this
signal. Intel recommends the following transition time for the VTT_PWRGD signal.
4.3.1.2.1
Transition Region
The transition region covered by this requirement is 300 mV to 900 mV. Once the VTTPWRGD signal
is in that voltage range, the processor is more sensitive to noise, which may be present on the signal.
The transition region when the signal first crosses the 300 mV voltage level and continues until the last
time it is below 900 mV.
4.3.1.2.2
4.3.1.2.3
Transition Time
The transition time is defined as the time the signal takes to move through the transition region. A
100-µs transition time will ensure that the processor receives a good transition edge.
Noise
The signal quality of the VTTPWRGD signal is critical to the correct operation of the processor. Every
effort should be made to ensure this signal is monotonic in the transition region. If noise or glitches are
present on this signal, the noise or glitches must be kept to less than 100 mV of a voltage drop from the
highest voltage level received to that point. This glitch must remain less than 100 mV until the
excursion ends by the voltage returning to the highest voltage previously received. Please see Figure
22 for an example graph of this situation and requirements.

Surface Mount Micro-FCBGA Package
The Mobile Intel Pentium III Processor-M will also be available in a surface mount, 479-ball Micro-
FCBGA package. The Low Voltage and Ultra Low Voltage processors will be available only in this
package. Mechanical specifications are shown in Table 39. Figure 26 through Figure 28 illustrate
different views of the package.
The Micro-FCBGA package may have capacitors placed in the area surrounding the die. Since the die-
side capacitors are electrically conductive, and only slightly shorter than the die height, care should be
taken to avoid contacting the capacitors with electrically conductive materials. Doing so may short the
capacitors and possibly damage the device or render it inactive. The use of an insulating material
between the capacitors and any thermal solution should be considered to prevent capacitor shorting.

6. VCC Thermal Specifications
In order to achieve proper cooling of the processor, a thermal solution (e.g., heat spreader, heat pipe, or
other heat transfer system) must make firm contact to the exposed processor die. The processor die
must be clean before the thermal solution is attached or the processor may be damaged.
Table 43 provides the Thermal Design Power (TDP) dissipation and the minimum and maximum TJ
temperatures for the Mobile Intel Pentium III Processor-M. The thermal solution should be designed to
ensure the junction temperature never exceeds the 100°C TJ specification while operating at the
Thermal Design Power. Additionally, a secondary failsafe mechanism in hardware should be provided
to shutdown the processor at 101°C to prevent permanent damage, as described in Section 3.1.3. TDP
is a thermal design power specification based on the worst case power dissipation of the processor
while executing publicly available software under normal operating conditions at nominal voltages.
Contact your Intel Field Sales Representative for further information.

NOTES:
1. TDP is defined as the worst case power dissipated by the processor while executing publicly available software
under normal operating conditions at nominal voltages that meet the load line specifications. The TDP number
shown is a specification based on Icc(maximum) and indirectly tested by Icc(maximum) testing. TDP definition
is synonymous with the Thermal Design Power (typical) specification referred to in previous Intel datasheets.
The Intel TDP specification is a recommended design point and is not representative of the absolute maximum
power the processor may dissipate under worst case conditions.
2. Not 100% tested. These power specifications are determined by characterization of the processor currents at
higher temperatures and extrapolating the values for the temperature indicated.
3. TJ is measured with the on-die thermal diode.
4. This specification applies only to the Ultra Low Voltage Mobile Intel Pentium III Processor-M.
6.1
Thermal Diode
The Mobile Intel Pentium III Processor-M has an on-die thermal diode that can be used to monitor the
die temperature (TJ). A thermal sensor located on the motherboard, or a stand-alone measurement kit,
may monitor the die temperature of the processor for thermal management or instrumentation
purposes. Table 44 and Table 45 provide the diode interface and specifications.
Note:
The reading of the thermal sensor connected to the thermal diode will not necessarily reflect the
temperature of the hottest location on the die. This is due to inaccuracies in the thermal sensor, on-die
temperature gradients between the location of the thermal diode and the hottest location on the die, and
time based variations in the die temperature measurement. Time based variations can occur when the
sampling rate of the thermal diode (by the thermal sensor) is slower than the rate at which the TJ
temperature can change.

Configuration
7.1
Description
The Mobile Intel Pentium III Processor-M has some configuration options that are determined by
hardware and some that are determined 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 frequencies (see product features section for specific
supported frequencies). Bit positions 18 to 19 of the Power-on Configuration 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. Software 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.

8.1
Alphabetical Signal Reference
A[35:3]# (I/O – AGTL)
The A[35:3]# (Address) signals define a 236-byte physical memory address space. When ADS# is
active, these signals transmit the address of a transaction; 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 transition of RESET#, each processor bus agent 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 asserted, the processor masks physical address bit 20
(A20#) before looking up a line in any internal cache and before driving a read/write transaction on the
bus. Asserting A20M# emulates the 8086 processor's address wrap-around at the 1-Mbyte boundary.
Assertion of A20M# is only supported in Real mode.
ADS# (I/O - AGTL)
The ADS# (Address Strobe) signal is asserted to indicate 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 architecture 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.
Mobile Intel® Pentium ® III Processor-M Datasheet

Processor Interface
R
BCLK, BCLK# (I)
The BCLK and BCLK# signals determines the system bus frequency.
On systems with Differential Clocking, both system bus agents must receive 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 system 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. The 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 observed and driven by both system bus agents and
must be connected to the appropriate pins/balls of both agents, if used. If the BINIT# driver is enabled
during the power-on configuration, BINIT# is asserted 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 count 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 assert 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 stall 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
80

R
wire-OR glitches associated with simultaneous edge transitions 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 Support 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 processor to stop issuing new requests, unless such
requests are part of an ongoing locked operation. The priority agent keeps BPRI# asserted until all of
its requests are completed and then releases 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-Ω resistor.
BSEL[1:0] (O – 3.3 V Tolerant)
The BSEL[1:0] (Select Processor System Bus Speed) signal is used 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 relationship 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.

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 from 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) supply 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 Kꢀ/1 Kꢀ (i.e., top resistor 500 ꢀ, bottom resistor 1 Kꢀ) for
830 chipset family. The Thevenin equivalent impedance of the VCMOSREF generation circuits must
be less than 0.75 Kꢀ/0.5 Kꢀ (i.e., top resistor 750 ꢀ, bottom resistor 500 ꢀ) for Intel 440MX chipset
family. Please refer to the platform design guidelines for other resistor divider recommendations.
D[63:0]# (I/O - AGTL)
The D[63:0]# (Data) signals are the data signals. These 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 pins/balls on both agents on the system bus.
DEFER# (I - AGTL)
The DEFER# (Defer) signal is asserted by an agent 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 connected 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 are used. During power-on
configuration, DEP[7:0]# signals can be enabled for ECC checking or disabled for no checking.
82
Mobile Intel® Pentium ® III Processor-M Datasheet
Processor Interface
R
DRDY# (I/O - AGTL)
The DRDY# (Data Ready) signal is asserted by the data 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 the 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 VSS with a 110-Ω, 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-type floating-point error reporting.
FLUSH# (I - 1.5 V Tolerant)
When the FLUSH# (Flush) input signal is asserted, the processor writes 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 agent 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 ignored when the processor is not in the Deep Sleep state.
This signal has an on-die pull-up to VCCT 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 indicate that it requires a snoop stall, which can be
continued by reasserting HIT# and HITM# together.
Mobile Intel® Pentium ® III Processor-M Datasheet
83
Processor Interface
R
IERR# (O - 1.5 V Tolerant Open-drain)
The IERR# (Internal Error) signal is asserted by the processor as the result of an internal error.
Assertion of IERR# is usually accompanied by a SHUTDOWN 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 handled in software or with the assertion of RESET#,
BINIT, or INIT#.
IGNNE# (I - 1.5 V Tolerant)
The IGNNE# (Ignore Numeric Error) signal is asserted 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-point instruction if a previous instruction 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 floating-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 backward 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 connected 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.
84
Mobile Intel® Pentium ® III Processor-M Datasheet
Processor Interface
R
When the priority agent asserts BPRI# to arbitrate for bus ownership, it waits 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 impedance 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 VCCT is required for this signal. Please 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 disabled. 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 routine. 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 logic, 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 pins/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 required 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.
Mobile Intel® Pentium ® III Processor-M Datasheet

Processor Interface
R
PWRGOOD (I – 1.8 V Tolerant)
PWRGOOD (Power Good) is a 1.8-V tolerant input. The processor requires this signal to be a clean
indication that clocks and the power supplies (VCC, VCCT, etc.) are stable and within their
specifications. Clean implies that the signal will remain 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 transition monotonically to a high (1.8V) state. Figure 12 through
Figure 14 illustrate the relationship of PWRGOOD to other 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 before 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 reset, RESET# must stay
active for at least 1 ms after VCC 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-Ω, 1% terminating resistor connected to VCCT 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 configuration, after an active-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.
86
Mobile Intel® Pentium ® III Processor-M Datasheet
Processor Interface
R
RS[2:0]# (I/O - AGTL)
The RS[2:0]# (Response Status) signals 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 assertion 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 agent guaranteeing correct parity.
RTTIMPEDP (I-Analog)
The RTTIMPEDP (RTT Impedance/PMOS) signal is used to configure the on-die AGTL termination.
Connect the RTTIMPEDP signal to VSS with a 56.2-Ω, 1% resistor.
SMI# (I - 1.5 V Tolerant)
The SMI# (System Management Interrupt) is asserted asynchronously by system 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 Acknowledge 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 Quick 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 test data from the processor. TDO provides the serial
output needed for JTAG support.

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 THERMDC (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 target to indicate that the target is ready to receive
write or implicit write-back data transfer. 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 Access Port (TAP) logic. The Mobile Intel Pentium III
Processor-M does not self-reset during power on; therefore, 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 provides a DC level reference voltage for the AGTL
input buffers. A voltage divider should be used to divide VCCT by 2/3. Resistor values of 1.00 kΩ and
2.00 kΩ are recommended. Decouple the VREF signal with three 0.1-µF high-frequency capacitors
close to the processor.
VTTPWRGD (I – 1.25 V)
The VTTPWRGD signal informs the processor to output the VID signals. 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 VTTPWRGD 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
A1.
Introduction
All Mobile Intel Pentium III Processor-Ms have internal 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 same as those for the
Mobile Pentium III Processor. The general desired topology is shown in Figure 2. Excluded from the
external circuitry are parasitics associated 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 adequate description for the filter.
The AC low-pass specification, with input at VCCT 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 VCCT to PLL1 should be less than 60 mV, which in practice implies
series resistance of less than 2 Ω. This also means that the pass band (from DC to 1 Hz)
attenuation below 0.43 dB for VCCT = 1.25 V.

not known and is assumed to be 0.15 Ω. Products with equivalent specifications may also be used.

To satisfy damping requirements, total series resistance in the filter (from VCCT to the top plate of the
capacitor) must be at least 0.35 Ω. 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 Ω, then a routing resistance of
at least 0.10 Ω is required. Be careful not to exceed the maximum resistance rule (2 Ω). For example,
if using discrete R1, the maximum DCR of the L should be less than 2.0 - 1.1 = 0.9 Ω, 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 Ω 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 resistance should be inserted between
VCCT and the inductor.
•
Any discrete resistor should be inserted between VCCT 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 because the LC filter by nature has an under-damped
response, which can cause resonance at the LC pole. Noise amplification at this band, although
not in the PLL-sensitive spectrum, could cause a fatal headroom reduction for analog circuitry.
The resistor serves to dampen the response. Systems 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 less 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-Ω
requirement.
