1.0 Introduction

®
Intel
Celeron® Processor up to 1.10 GHz
The Intel® Celeron® processor is based on the P6 microarchitecture and is optimized for the Value PC market segment. The Intel Celeron processor, like the Pentium Dynamic Execution microarchitecture and executes MMX™ technology instructions for enhanced media and communication performance. The Intel Celeron processor also utilizes multiple low­power states such as AutoHALT, S t o p-Grant , Sleep, and Deep Sleep to con serv e p ower dur ing idle times.
The Intel Celeron processor is capabl e of running today ’ s mos t common PC appli cations with up to 4 GB of cacheable memory space. As this processor is intended for Value PC systems, it does not provide multiprocessor support. The Pentium II and Pentium multiprocessor system designs.
To be cost-effective at both the processor and system level, the Intel Celeron processor utilizes cost-effective packaging technologies. They are the S.E.P. (Single-Edge Processor) package, the PPGA (Plastic Pin Grid Array) package, the FC-PGA (Flip-Chip Pin Grid Array) package, and the FC-PGA2 (Flip-Chip Pin Grid Array) package. Refer to the Intel Specification Update for the latest packaging and frequency support information (Order Number
243337).
Note: This datasheet describes the Intel Celeron processor for the PPGA package, FC-PGA/FC-PGA2
packages, and the S.E.P. Package versions. Unless otherwise specified, the information in this document applies to all versions and information on PGA packages, refer to both PPGA and FC-PGA packages.

1.1 Terminology

II processor, features a
®
III processors should be used for
®
Celeron® Processor
In this document, a ‘#’ symbol after a signal name refers to an active low signal. This means that a
signal is in the active state (based on the name of the signal) when driven to a low level. For
example, when FLUSH# is low, a flush has been requested. When NMI is high, a nonmaskable
interrupt has occurred. In the case of signals where the name does not imply an active state but
describes part of a binary seq uence (such as address or data), the ‘#’ symbol implies that the signal
is inverted. For example, D[3:0] = ‘HLHL’ refers to a hex ‘A ’, and D[3:0]# = ‘LHLH’ also refers to
a hex ‘A’ (H= High logic level, L= Low logic level).
The term “system bus” refers to the interface between the processor, system core logic (a.k.a. the
AGPset components), and other bus agents. The system bus is an interface to the processor,
memory, and I/O.

1.1.1 Package Terminology

The following terms are used often in this document and are explained here for clarification:
Processor substrate—The structure on which passive components (resistors and capacitors)
are mounted.
Processor core—The processor’s execution engine.
S.E.P. Package—Single-Edge Processor Package, which consists of a processor substrate,
processor core, and passive compone nts. This package d iffers f rom the S.E.C. C artridge as this processor has no external plastic cover, thermal plate, or latch arms.
PPGA package—Plastic Pin Grid Array package. The package is a pinned laminated printed
circuit board structure.
FC-PGA — Flip-Chip Pin Grid Array. The FC-PGA uses the same 370-pin zero insertion
force socket (PGA370) as the PPGA. Thermal solutions are attached directly to the back of the processor core package without the use of a thermal plate or heat spreader.
FC-PGA2 — Flip Chip Pin Gr id Array 2. The FC-P G2A uses t he same 370 -pin zero inser tion
force socket (PGA370) as the PPGA. The FC-PGA2 package contains an Integrated Heat Spreader that covers the processor die.
Keepout zone - The area on or near a FC-PGA/FC-PGA2 packaged processor that system
designs can not utilize.
Keep-in zone - The area of a FC-PGA packaged processor that thermal solutions may utilize.
Additional terms referred to in this and other related documentation:
SC242—242-contact slot connector. A processor in the S.E.P. Package uses this connector to
interface with a system board.
370-pin socket (PGA370)—The zero insertion force (ZIF) socket in which a processor in the
PPGA package will use to interface with a system board.
Retention mechanism—A mechanical assembly which holds the package in the SC242
connector.

1.1.2 Processor Naming Convention

A letter(s) is added to certain processo rs (e.g ., 5 33 A MHz) when the core frequency alone may not
uniquely identify the processor. Below is a summary of what each letter means as well as a table
listing all the FC-PGA/FC-PGA2 processors for the PGA370 socket.

2.0 Electrical Specifications

2.1 System Bus and VREF

®
Intel
Celeron® Processor up to 1.10 GHz
Celeron processor signals use a variation of the low voltage Gunning Transceiver Logic (GTL) signaling technology. The Intel
Celeron processor system bus specification is similar to the GTL specification, but has been enhanced to provide larger noise margins and reduced ringing. The improvements are accomplished by increasing the termination voltage level and controlling the edge rates. Because this specification is dif ferent f rom the stand ard GTL specification, it is referred to as Assisted Gunning Transceiver Logic (AGTL+) in this document.
The Celeron processor varies from the Pentium Pro processor in its output buffer implementation. The buffers that drive the system bus signals on the Celeron processor are actively driven to V
CC
for one clock cycle during the low-to-high transition. This improves rise times and
CORE
reduces overshoot. These signals should still be considered open-drain and require termination to a supply that provides the logic-high signal level.
The AGTL+ inputs use differential receivers which require a reference signal ( V
REF). VREF is used
by the receivers to determine if a signal is a logic-high or a logic-low, and is provided to the processor core by either the processor substrate (S.E.P. Package) or the motherboard (PGA370 socket). Local V
REF copies should be generate d on the motherboard for all other devices on the
AGTL+ system bus. Termination is used to pull the bus up to the high voltage level and to control reflections on the
transmission line. The processor may contain termination resistors (S.E.P. Package, FC-PGA Package, and FC-PGA2 Package) that provide termination for one end of the Intel Celeron processor system bus. Otherwise, this termination must exist on the motherboard.
Solutions exist for single-ended termination as well, though this implementation changes system design and eliminate backwards compatibility for Celeron processors in the PPGA package. Single-ended termination designs must still provide an AGTL+ termination resistor on the motherboard for the RESET# signal.
The AGTL+ bus depends on incident wave switching. Therefore timing calculations for AGTL+ signals are based on motherboard flight time as opposed to capacitive deratings. Analog signal simulation of the Intel Celeron processor system bus, including trace lengths, is highly recommended when designing a system. See the Pentium and the Pentium

2.2 Clock Control and Low Power St ates

Celeron processors allow the use of AutoHALT, Stop-Grant, Sleep, and Deep Sleep states to reduce power consumption by stopping the clock to internal sections of the processor, depending on each particular state. See Figure 1 for a visual representation of the Intel Celeron processor low power states.
For the processor to fully realize the low current consumption of the Stop-Grant, Sleep, and Deep Sleep states, a Model Specific Register (MSR) bit must be set. For the MSR at 02Ah (hex), bit 26 must be set to a ‘1’ (this is the power on default setting) for the processor to stop all internal clocks during these modes. For more information, see the Pentium (Order Number 243502).

2.2.1 Normal State—State 1

This is the normal operating state for the processor.

2.2.2 Aut oHALT Power Down State—State 2

AutoHALT is a low power state entered when the processor executes the HALT instruction. The processor will transition to the Normal state upon the occurrence of SMI#, BINIT#, INIT#, or LINT[1:0] (NMI, INTR). RESET# will cause the processor to immediately initialize itself.
The return from a System Management Interrupt (SMI) handler can be to either Normal Mode or the AutoHALT Power Down state. See the Intel Architecture Software Developer's Manual, Volume III: System Programmer's Guide (Order Number 243192) for more information.
FLUSH# will be serviced during the AutoHALT state, and the processor will return to the AutoHALT state.
The system can generate a STPCLK# while the processor is in the AutoHALT Power Down state. When the system deasserts the STPCLK# interrupt, the processor will return execution to the HALT state.

2.2.3 Stop-Grant State—State 3

The Stop-Grant state on the processor is entered when the STPCLK# signal is asserted. Since the AGTL+ signal pins receive power from the system bus, these pins should not be driven
(allowing the level to return to V state. In addition, all other input pins on the system bus should be driven to the inactive state.
BINIT# will not be serviced while the processor is in Stop-Grant state. The event will be latched and can be serviced by software upon exit from Stop-Grant state.
FLUSH# will not be serviced during Stop-Grant state. RESET# will cause the processor to immediately initialize itself, but the processor will stay in
Stop-Grant state. A transition back to the Normal state will occur with the deassertion of the STPCLK# signal.
A transition to the HALT/Grant Snoop state will occur when the processor detects a snoop on the system bus (see Section 2.2.4). A transition to the Sleep state (see Section 2.2.5) will occur with the assertion of the SLP# signal.
While in the Stop-Grant State, SMI#, INIT#, and LINT[1:0] will be latched by the processor, and only serviced when the processor returns to the Normal State. Only one occurrence of each event will be recognized upon return to the Normal state.

Celeron® Processor up to 1.10 GHz

2.2.4 HALT/Grant Snoop State—State 4

The processor will respond to snoop transactions on the Celeron processor system bus while in Stop-Grant state or in AutoHALT Power Down state. During a snoop transaction, the processor enters the HAL T/Gran t Snoop state. The processor will stay in this state until the snoop on the Intel Celeron processor system bus has been serviced (whether by the processor or another agent on the Intel Celeron processor system bus). After the snoop is serviced, the processor will return to the Stop-Grant state or AutoHALT Power Down state, as appropriate.

2.2.5 Sleep State—State 5

The Sleep state is a very low power state in which the processor maintains its context, maintains the phase-locked loop (PLL), and has stopped all internal clocks. The Sleep state can only be entered from Stop-Grant state. Once in the Stop-Grant state, the SLP# pin can be asserted, causing the processor to enter the Sleep state. The SLP# pin is not recognized in the Normal o r AutoHALT states.
Snoop events that occur while in Sleep State or during a transition into or out of Sleep state will cause unpredictable behavior.
In the Sleep state, the processor is incapable of responding to snoop transactions or latching interrupt signals. No transitions or assertions of signals (with the exception of SLP# or RESET#) are allowed on the system bus while the processor is in Sleep state. Any transition on an input signal before the processor has returned to Stop-Grant state will result in unpredictable behavior.
If RESET# is driven active while the processor is in the Sleep state, and held active as specified in the RESET# pin specification, then the processor will reset itself, ignoring the transition through Stop-Grant State. If RESET# is driven active while the processor is in the Sleep State, the SLP# and STPCLK# signals should be deasserted immediately after RESET# is asserted to ensure the processor correctly executes the Reset sequence.
Datasheet 17
®
Intel
Celeron® Processor up to 1.10 GHz
While in the Sleep state, the processor is capable of entering its lowest power state, the Deep Sleep state, by stopping the BCLK input. (See Section 2.2.6.) Once in the Sleep state, the SLP# pin can be deasserted if another asynchronous system bus event occurs. The SLP# pin has a minimum assertion of one BCLK period.

2.2.6 Deep Sleep State—State 6

The Deep Sleep state is the lowest power state the processor can enter while maintaining context. The Deep Sleep state is entered by stopping the BCLK input (after the Sleep state was entered from the assertion of the SLP# pin). The processor is in Deep Sleep state immediately after BLCK is stopped. It is recommended that the BLCK input b e held low durin g the Deep Sleep S tate. Stop ping of the BCLK input lowers the overall current consumption to leakage levels.
To re-enter the Sleep state, the BCLK input must be restarted. A period of 1 ms (to allow for PLL stabilization) must occur before the processor can be considered to be in the Sleep State. Once in the Sleep state, the SLP# pin can be deasserted to re-enter the Stop-Grant state.
While in Deep Sleep state, the processor is incapable of responding to snoop transactions or latching interrupt signals. No transitions or assertions of signals are allowed on the system bus while the processor is in Deep Sleep state. Any transition on an input signal before the processor has returned to Stop-Grant state will result in unpredictable behavior.

2.2.7 Clock Control

BCLK provides the clock signal for the processor and on die L2 cache. During AutoHALT Power Down and Stop-Grant states, the processor processes a system bus snoop. The processor does not stop the clock to the L2 cache during AutoHALT Power Down or Stop-Grant states. Entrance into the Halt/Grant Snoop state allows the L2 cache to be snooped, similar to the Normal state.
When the processor is in the Sleep or Deep Sleep states, it does not respond to interrupts or snoop transactions. During the Sleep state, the internal clock to the L2 cache is not stopped. During the Deep Sleep state, the internal clock to the L2 cache is stopped. The internal clock to the L2 cache will be restarted only after the internal clocking mechanism for the processor is stable (i.e., the processor has re-entered Sleep state).
PICCLK should not be removed during the AutoHALT Power Down or Stop-Grant states. PICCLK can be removed during the Sleep or Deep Sleep states. When transitioning from the Deep Sleep state to the Sleep state, PICCLK must be restarted with BCLK.

2.3 Power and Ground Pins

There are five pins defined on the S.E.P. Package for voltage identification (VID) and four pins on the PPGA, FC-PGA, and FC-PGA2 packages. These pins specify the voltage required by the processor core. These have been added to cleanly support voltage specification variations on current and future Celeron processors.
For clean on-chip power distribution, Intel Celeron processors in the S.E.P. Package have 27 V (power) and 30 V voltage levels to the components. V pins, while 4 V For only the S.E.P. Package, one V

2.3.1 Phase Lock Loop (PLL) Power

It is highly critical that phase lock loop power delivery to the processor meets Intel’s requirements. A low pass filter is required for power delivery to pins PLL1 and PLL2. This serves as an isolated, decoupled power source for the internal PLL.

2.4 Processor Decoupling

Due to the large number of transistors and high internal clock speeds, the processor is capable of generating large average current swings between low and f ull power states. This causes voltages on power planes to sag below their nominal values if bulk decoupling is not adequate. Care must be taken in the board design to ensure that the voltage provided to the processor remains within the specifications listed in Table 5. Failure to do so can result in timing violations or a reduced lifetime of the component.

2.4.1 System Bus AGTL+ Decoupling

The S.E.P. Package and FC-PGA/FC-PGA2 packages contain high frequency decoupling capacitance on the processor substrate, where the PPGA package does not. Therefore, Celeron processors in the PGA packages require high frequency decoupling on the system motherboard. Bulk decoupling must be provided on the motherboard for proper AGTL+ bus operation for all packages. See AP-585, Pentium 587, Pentium

2.5 Voltage Identi fication

The processor’s voltage identification (VID) pins can be used to automatically select the VCC voltage from a compatible voltage regulator. There are five VID pins (VID[4:0]) on the S.E.P. Package, while there are only four (VID[3:0]) on the PGA packages. This is because there are no Celeron processors in the PGA package that require more than 2.05 V (see Table 2).
VID pins are not signals, but rather are an open or short circuit to V combination of opens and shorts defines the processor core’s required voltage. The VID pins also allow for compatibility with current and future Intel Celeron processors.
Note that the ‘11 11 1’ (all opens) ID can be used to detect the abs ence of a pr ocessor cor e in a given slot (S.E.P. Package only), as long as the power supply used does not affect the VID signals. Detection logic and pull-ups should not affect VID inputs at the power source (see Section 7.0).
External logic monitoring the VID signals or the voltage regulator may require the VID pins to be pulled-up. If this is the case, the VID pins should be pulled up to a TTL-compatible level with external resistors to the power source of the regulator.
The power source chosen must be guaranteed to be stable whenever the voltage regulator’s supply is stable. This will prevent the possibility of the processor supply going above the specified V
CC
in the event of a failure in the supply for the VID lines. In the case of a DC-to-DC
CORE
converter, this can be accomplished by using the input voltage to the converter for the VID line pull-ups. In addition, the power supply must supply the requested voltage or disable itself.

2.6 System Bus Unused Pins

Intel
Celeron® Processor up to 1.10 GHz
All RESERVED pins must remain unconnected. Connection of these pins to VCC
CORE
, VSS, or to any other signal (including each other) can result in component malfunction or incompatibility with future Celeron processor products. See Section 5.0 for a pin listing of the processor and the location of each RESERVED pin.
For Intel Celeron processors in the S.E.P. Package, the TESTHI pin must be at a logic-high level when the core power supply comes up. For more information, please refer to erratum C26 of the
®
Intel
Celeron® Processor Specification Update (Order Number 243748). Also note that the
TESTHI signal is not available on Intel Celeron processors in the PGA package. PICCLK must be driven with a valid clock input and the PICD[1:0] lines must be pulled-up to
2.5 V even when the APIC will not be used. A separate pull-up resistor must be provided for each PICD line.
For reliable operation, always connect unused inputs or bi-directional signals to their deasserted signal level. The pull-up or pul l-down res i stor value is system dependent and should be c hosen such that the logic-high (V
) and logic-low (VIL) requirements are met.
IH
For the S.E.P. Package, unused AGTL+ inputs should not be connected as the package substrate has termination resistors. On the other hand, the PGA packages do not have AGTL+ termination in their package and must have any unused AGTL+ inputs terminated through a pull-up resistor. For designs that intend to only support the FC-PGA/FC-PGA2 processors, unused AGTL+ inputs will be terminated by the processor’s on-die termination resistors and, thus, do not need to be terminated on the motherboard. However, the reset pin should always be terminated on the motherboard.
For unused CMOS inputs, active-low signals should be connected through a pull-up resistor to meet V meet V
requirements and active-high signals should be con nected through a pull-down res istor to
IH
requirements. Unused CMOS outputs can be left unconnected. A resistor must be used
IL
when tying bi-directional signals to power or ground. For any signal pulled to either power or ground, a resistor will allow for system testability.

2.7 Processor System Bus Signal Groups

To simplify the following discussion, the Celeron processor system bus signals have been combined into groups by buffer type. All Celeron processor system bus outputs are open drain and require a high-level source provided externally by the termination or pull-up resistor.
AGTL+ input signals have dif fe rential input buffers, which use V output signals require termination to 1.5 V. In this document, the term "AGTL+ Input" refers to the AGTL+ input group as well as the AGTL+ I/O group when receiving. Similarly, "AGTL+ Output" refers to the AGTL+ output group as well as the AGTL+ I/O group when driving.
EMI pins (S.E.P. Package only) should be connected to motherboard ground and/or to chassis ground through zero ohm (0 ) resistors. The zero ohm resistors should be placed in close proximity to the SC242 conn ect or. The path to chassis ground should be short in l eng th and have a low impedance.
The PWRGOOD, BCLK, and PICCLK inputs can each be driven from ground to 2.5 V. Other CMOS inputs (A20M#, IGNNE#, INIT#, LINT0/INTR, LINT1/NMI, PREQ#, SMI, SLP#, and STPCLK#) must be pulled up to V

2.7.1 Asynchronous Vs. Synchronous for System Bus Signals

All AGTL+ signals are synchronous to BCLK. All of the CMOS, APIC, and TAP signals can be applied asynchronously to BCLK. All APIC signals are synchronous to PICCLK. All TAP signals are synchronous to TCK.

2.7.2 System Bus Frequency Select Signal (BSEL[1:0])

The BSEL pins have two functions. First, they can act as outputs and can be used by an external clock generator to select the proper system bus frequency. Second, they can act as an inputs and can be used by a system BIOS to detect and report the processor core frequency. See the Intel

2.8 Test Access Port (TAP ) Connection

®
Due to the voltage levels supported by other components in the Test Access Port (TAP) logic, it is recommended that the Celeron processor be first in the TAP chain and followed by any other components within the system. A translation buffer should be used to connect to the rest of the chain unless one of the other components is capable of accepting a Vcc Similar considerations must be made for TCK, TMS, and TRST#. Two copies of each signal may be required with each driving a different voltage level.
A Debug Port may be placed at the start and end of the TAP chain with the TDI of the first component coming from the Debug P ort and the TD O from th e last compo nent going t o the Deb ug Port.

2.9 Maximum Ratings

Table 4 contains the Celeron processor stress ratings only. Functional operation at the absolute

2.10 Processor DC Specifi cations

The processor DC specifications in this section are defined for the Celeron processor. See
Section 7.0 for signal definitions and Section 5.0 for signal listings.
Most of the signals on the Intel Celeron processor system bus are in the AGTL+ signal group. These signals are specified to be terminated to 1.5 V. The DC specifications for these signals are listed in Table 6.
To allow connection with other devices, the Clock, CMOS, APIC, and TAP signals are designed to interface at non-AGTL+ levels. The DC specifications for these pins are listed in Table 7.
Table 5 through Table 8 list the DC specifications for Intel Celeron processors operating at 66 MHz
Intel Celeron processor system bus frequencies. Specifications are valid only while meeting specifications for case temperature, clock frequency, and input voltages. Care should be taken to read all notes associated with each parameter.

2.12 System Bus AC Specifications

The Celeron processor system bus timings specified in this section are defined at the Intel Celeron processor edge fingers and the processor core pins. T imings specified at the processor edge fingers only apply to the S.E.P. Package and timings given at the processor core pins apply to all S.E.P. Package and PGA packages. Unless otherwise specified, timings are tested at the processor core during manufacturing. Timings at the processor edge fingers are specified by design characterization. See Section 7.0 for the Intel Celeron processor signal definitions. Note that at
66 MHz system bus operation, the Intel Celeron processor timings at the processor edge fingers are identical to the Pentium II processor timings at the edge fingers. See the Pentium
II Processor at 233, 266, 300, and 333 MHz (Order Number 243335) for more detail.
Table 9 through Table 26 list the AC specifications associated with the Intel Celeron processor
system bus.

NOTES:
1. Unless otherwise noted, all specifications in this table apply to all Celeron processor frequencies.
2. All AC timings for the AGTL+ signals are referenced to the BCLK rising edge at 0.70 V at the processor edge fingers. This reference is to account for trace length and capacitance on the processor substrate, allowing the processor core to receive the signal with a reference at 1.25 V. All AGTL+ signal timings (address bus, data bus, etc.) are referenced at 1.00 V at the processor edge fingers.
3. All AC timings for the CMOS signals are referenced to the BCLK rising edge at 0.70 V at the processor edge fingers. This reference is to account for trace length and capacitance on the processor substrate, allowing the processor core to receive the signal with a reference at 1.25 V. All CMOS signal timings (compatibility signals, etc.) are referenced at 1.25 V at the processor edge fingers.
4. The internal core clock frequency is derived from the Intel Celeron processor system bus clock. The sys tem bus clock to core clock ratio is determined during initialization. Table 12 shows the supported ratios for each processor.
5. The BCLK period allows a +0.5 ns tolerance for clock driver variation.
6. This specification applies to Intel Celeron processors when operating at a system bus frequency of 66 MHz.
7. The BCLK offset time is the absolute difference needed between the BCLK signal arriving at the Intel Celeron processor edge finger at 0.5 V vs. arriving at the core logic at 1.25 V. The positive offset is needed to account for the delay between the SC242 connector and processor core. The positive offset ensures both the processor core and the core logic receive the BCLK edge concurrently.
8. See Sect ion 3.1 for Intel Celeron processor system bus clock signal quality specifications.
9. Not 100% tested. Specified by design characterization as a clock driver requirement.

6. This specification applies to the Intel Celeron processor when operating at a system bus frequency of 66 MHz.
7. See Section 3.1 for Intel Celeron processor system bus clock signal quality specifications.
8. Due to the difficulty of accurately measuring clock jitter in a system, it is recommended that a clock driver be used that is designed to meet the period stability specification into a test load of 10 to 20 pF. This should be measured on the rising edges of adjacent BCLKs crossing 1.25 V at the processor core pin. The jitter present must be accounted for as a component of BCLK timing skew between devices.
9. The clock driver’s closed loop jitter bandwidth must be set low to allow any PLL-based device to track the jitter created by the clock driver. The –20 dB attenuation point, as measured into a 10 to 20 pF load, should be less than 500 kHz. This specification may be ensured by design characterization and/or measured with a spectrum analyzer.

3.0 System Bus Signal Simulations

Signals driven on the Celeron processor system bus should meet signal quality specifications to ensure that the components read data proper ly and to ensur e that incomi ng signal s do not af fect the long term reliability of the component. Specifications are provided for simulation at the processor core; guidelines are provided for correlation to the processor edge fingers. These edge finger guidelines are intended for use during testing and measurement of system signal integrity. Violations of these guidelines are permitted, but if they occur, simulation of signal quality at the processor core should be performed to ensure that no violations of signal quality specifications occur. Meeting the specifications at the processor core in Table 28, Table 31, and Table 34 ensures that signal quality effects will not adversely affect processor operation, but does not necessarily guarantee that the guidelines in Table 30, Table 33, and Table 35 will be met.

3.1 System Bus Clock (BCLK) Signal Quality Specifications and Measurement Guidelines

Table 28 describes the BCLK signal quality specifications at the processor core for both S.E.P. and
PPGA Packages. Table 29 shows the BCLK and PICCLK signal quality specifications at the processor core for the FC-PGA/FC-PGA2 packages. Table 30 describes guidelines for signal quality measurement at the processor edge fingers. Figure 11 describes the signal quality waveform for the system bus clock at the processor core pins; Figure 12 describes the signal quality waveform for the system bus clock at the processor edge fingers.

3.3.1 Overshoot/Undershoot Guidelines

Rising-Edge Ringback
Undershoot
Settling Limit
Falling-Edge Ringback
Overshoot (or undershoot) is the absolute value of the maximum voltage above the nominal high voltage or below V
SS. The overshoot/undershoot guideline limits transitions beyond VCC or VSS
due to the fast signal edge rates. (See Figure 14 for non-AGTL+ signals.) The processor can be damaged by repeated overshoot events on the volt age t oleran t buffers if the charge is lar ge enou gh (i.e., if the overshoot is great enough). The PPGA and S.E.P. packages have 2.5 V tolerant buffers and the FC-PGA/FC-PGA2 packages has 1.5 V or 2.5 V tolerant buffers.
However, excessive ringback is the dominant detrimental system timing effect resulting from overshoot/undershoot (i.e., violating the overshoot/undershoot guideline will make satisfying the ringback specification difficult). The overshoot/undershoot guideline is 0.7 V for the PPGA and S.E.P. packages and 0.3 V for the FC-PGA/FC-PGA2 packages and assumes the absence of diodes on the input. These guidelines should be verified in simulations without the on-chip ESD prote cti on d i od es p resent because the diodes will begin clamping the signals (2.5 V tolerant signals for the S.E.P. and PPGA packages, and 2.5 V or 1.5 V tolerant signals for the FC-PGA/ FC-PGA2 packages) beginning at approximately 0.7 V above the appropriate supply and 0.7 V below V
SS. If signals are not reaching the clamping voltage, this will not be an issue. A system
should not rely on the diodes for overshoot/undershoot protection as this will negatively affect the life of the components and make meeting the ringback specification very difficult.

3.3.2 Ringback Specification

Ringback refers to the amount of reflection seen after a signal has switched. The ringback specification is the voltage that the signal rings back to after achieving its maximum absolute value. (See Figure 14 for an illustration of ringback.) Excessive ringback can cause false signal detection or extend the propagation delay. The ringback specification applies to the input pin of each receiving agent. Violations of the signal ringback specification are not allowed under any circumstances for non-AGTL+ signals.
Ringback can be simulated with or without the input protection diodes that can be added to the input buffer model. However, signals that reach the clamping voltage should be evaluated further. See Ta ble 34 for the signal ringback specifications for non-AGTL+ signals for simulations at the processor core, and Table 35 for guidelines on measuring ringback at the edge fingers. Table 36 lists the ringback specifications for the FC-PGA/FC-PGA2 packages.

3.3.3 Settling Limit Guideline

Settling limit defines the maximum amount of ringing at the receiving pin that a signal must reach before its next transition. The amount allowed is 10 percent of the total signal swing (V
HI
above and below its final value. A signal should be within the settling limits of its final value, when either in its high state or low state, before it transitions again.
Signals that are not within their settling limit before transitioning are at risk of unwanted oscillations which could jeopardize signal integrity. Simulations to verify settling limit may be done either with or without the input protection diodes present. Violation of the settling limit guideline is acceptable if simulations of 5 to 10 successive transitions do not show the amplitude of the ringing increasing in the subsequent transitions.

3.4 AGTL+ Signal Quality Specifications and Measurement Guidelines (FC-PGA/FC-PGA2 Packages)

3.4.1 Overshoot/Undershoot Guidelines (FC-PGA/FC-PGA2 Packages)

Overshoot (or undershoot) is the absolute value of the maximum voltage above the nominal high voltage or below V signal edge rates. The processor can be damaged by repeated overshoot events on 1.5 V or 2.5 V tolerant buffers if the charge is large enough (i.e., if the overshoot is great enough). Determining the impact of an overshoot/undershoot condition requires knowledge of the magnitude, the pulse direction and the activity factor (AF). Permanent damage to the processor is the likely result of excessive overshoot/undershoot. Violating the overshoot/undershoot guideline will also make satisfying the ringback specification difficult.

V
LO
)
When performing simulations to determine impact of overshoot and overshoot, ESD diodes must be properly characterized. ESD protection diodes do not act as voltage clamps an d will not provide overshoot or undershoot protection. ESD diodes modeled within Intel I/O Buffer models do not clamp undershoot or overshoot and will yield correct simulation results. If other I/O buffer models are being used to characterize the FC-PGA/FC-PGA2 processor performance, care must be taken to ensure that ESD models do not clamp extreme voltage levels. Intel I/O Buffer models also contain I/O capacitance characterization. Therefore, removing the ESD diodes from an I/O Buffer model will impact results and may yield excessive overshoot/undershoot.

3.4.2 Overshoot/Undershoot Magnitude (FC-PGA/FC-PGA2 Packages)

Magnitude describes the maximum potential difference between a signal and its voltage reference level, V using one probe (probe to signal and GND lead to V V signal undershoot. Today’s oscillosco pes can easily calcula te the true un dershoot wa veform using a Math function where the Signal waveform is subtracted from the V undershoot waveform can also be obtained with the following oscilloscope data file analysis:
Note: The converted undershoot waveform appears as a positive (overshoot) signal.
Note: Overshoot (rising edge) and undershoot (falling edge) conditions are separate and their impact
must be determined independently.
SS (overshoot) and VTT (undershoot). While overshoot can be measured relative to VSS
SS), undershoot must be measured relative to
TT. This can be accomplished by simultaneously measuring the VTT plane while measuring the
TT waveform. The true
Converted Undershoot Waveform = VTT– Signal_measured
Datasheet 59
®
Intel
Celeron® Processor up to 1.10 GHz
After the true waveform conversion, the undershoot/overshoot specifications shown in Table 38 and Table 39 can be applied to the converted undershoot waveform using the same magnitude and pulse duration specifications used with an overshoot waveform.
Overshoot/undershoot magni tude levels mus t observe the Absolut e Maximum Speci fications lis ted in Table 38 and Table 39. These specifications must not be violated at any time regardless of bus activity or system state. Within these specifications are threshold levels that define different allowed pulse durations. Provided that the magnitude of the overshoot/undershoot is within the Absolute Maximum Specifications (2.18V), the puls e magnitude, duration and activity factor must all be used to determine if the overshoot/undershoot pulse is within specifications.

3.4.3 Overshoot/Undershoot Pulse Duration (FC-PGA/FC-PGA2 Packages)

Pulse duration describes the total time an overshoot/undershoot event exceeds the overshoot/ undershoot reference voltage (Vos_ref = 1.635 V). The total time could encompass several oscillations above the reference voltage. Multiple overshoot/undershoot pulses within a single overshoot/undershoot event may need to be measured to determine the total pulse duration.
Note: Oscillations below the reference voltage can not be subtracted from the total overshoot/undershoot
pulse duration.
Note: Multiple Overshoot/Undershoot events occurring within the same clock cycle must be considered
together as one event. Using the worst case Overshoot/Undershoot Magnitude, sum together the individual Pulse Durations to determine the total Overshoot/Undershoot Pulse Duration for that total even t .

3.4.4 Acti vity Factor (FC-PGA/FC-PGA2 Packages)

Activity Factor (AF) describes the frequency of overshoot (or undershoot) occurrence relative to a clock. Since the highest frequency of assertion of an AGTL+ or a CMOS signal is every other clock, an AF = 1 indicates that the specific overshoot (or undershoot) waveform occurs EVERY OTHER clock cycle. Thus, an AF = 0.01 indicates that the specific overshoot (or undershoot) waveform occurs one time in every 200 clock cycles.
The specifications provided in Table 38 and Table 39 show the Maximum Pulse Duration allowed for a given Overshoot/Undershoot Magnitude at a specific Activity Factor. Each table entry is independent of all others, meaning that the Pulse Duration reflects the existence of overshoot/ undershoot events of that magnitude ONLY. A platform with an overshoot/undershoot that just meets the pulse duration for a specific magnitude where the AF < 1, means that there can be NO other overshoot/undershoot events, even of lesser magnitude (note that if AF = 1, then the event occurs at all times and no other events can occur).
Note: Activity factor for AGTL+ signals is referenced to BCLK frequency.
Note: Activity factor for CMOS signals is referenced to PICCLK frequency.

3.4.5 Reading Overshoot/Undershoot Specification Tables (FC-PGA/ FC-PGA2 Packages)

The overshoot/undershoot specification for the FC-PGA/FC-PGA2 packages processor is not a simple single value. Instead, many factors are needed to determine the over/undershoot specification. In additi on to t he mag nit ude o f the overshoot, the following parameters must also be known: the junction temperature the processor will be operating, the width of the overshoot (as measured above 1.635 V) and the Activity Factor (AF). To determine the allowed overshoot for a particular overshoot event, the following must be done:
1. Determine the signal group that particular signal falls into. If the signal is an AGTL+ signal operating with a 66 MHz system bus, use Table 38 (66 MHz AGTL+ signal group). If the signal is a CMOS signal, use Table 39 (33 MHz CMOS signal group).
2. Determine the maximum junction temperature (Tj) for the range of pro cessor s that the system will support (80
o
C or 90oC).
3. Determine the Magnitude of the overshoot (relative to V
4. Determine the Activity Factor (how often does this overshoot occur?)
5. From the appropriate Specification table, read off the Maximum Pulse Duration (in ns) allowed.
6. Compare the specified Maximum Pulse Duration to the signal being measured. If the Pulse Duration measured is less than the Pulse Duration shown in the table, then the signal meets the specifications.
The above procedure is similar for undershoots after the undershoot waveform has been converted to look like an overshoot. Undershoot events must be analyzed separately from Overshoot events as they are mutually exclusive.
Table 37 shows an example of how the maximum pulse duration is determined for a given
waveform.

NOTES:
1. Corresponding Maximum Pulse Duration Specification – 3.2 ns
2. Pulse Duration (measured) – 2.0 ns
Given the above parameters, and using Table 38 (90oC/AF=0.1 column) the maximum allowed pulse duration is 3.2 ns. Since the measured pulse duration is 2.0ns, this parti cul ar ov ers hoo t event passes the overshoot specifications, although this doesn't guarantee that the combined overshoot/ undershoot events meet the specifications.

3.4.6 Determining if a System meets the Overshoot/Undershoot Specifications (FC-PGA/FC-PGA2 Pack ages)
The overshoot/undershoot specifications listed in the following tables specify the allowable overshoot/undershoot for a single overshoot/undershoot event. However most systems will have multiple overshoot and/or undershoot events that each have their own set of parameters (duration, AF and magnitude). While each overshoot on its own may meet the overshoot specification, when the total impact of all overshoot events is accounted for, the system may fail. A guideline to ensure a system passes the oversh oot and undershoot specifications is shown below. It is important to meet these guidelines; otherwise, contact your Intel field representative.
1. Insure no signal (CMOS or AGTL+) ever exceed the 1.635 V; OR
2. If only one oversho ot/un dershoot event magn itude o ccurs, ensure it meets the ove r/unders hoot specifications in the following tables; OR
3. If multiple overshoots and/or multiple undershoots occur, measure the worst case pulse duration for each magnitude and compare the r esults against th e AF = 1 specification s. If all of these worst case overshoot or undershoot events meet the specifications (measured time < specifications) in the table (where AF=1), then the system passes.
The following notes apply to Table 38 and Table 39.
NOTES:
1. Overshoot/Undershoot Magnitude = 2.18 V is an Absolute value and should never be exceeded
2. Overshoot is measured relative to V
3. Undershoot is measured relative to VTT
4. Overshoot/Undershoot Pulse Duration is measured relative to 1.635 V.
5. Ringbacks below V
TT can not be subtracted from Overshoots/Undershoots.
6. Lesser Undershoot does not allocate longer or larger Overshoot.
7. Consult the appropriate layout guidelines provided in the specific platform design guide.
8. All values specified by design characterization.

4.0 Thermal Specifications and Design Considerations

This section provides needed data for designing a thermal solution. However, for the correct thermal measuring processes, refer to AP-905, Intel Guidelines (Order Number 245087). For the FC-PGA/FC-PGA2 using flip chip pin grid array packaging technology, Intel specifies the junction temperature (T and PPGA package, Intel specifies the case temperature (T

4.1 Thermal Specifications

Table 40 provides both the Processor Power and Heatsink Design Target for Celeron processors.
Processor Power is defined as the total power dissipated by the processor core and its package. Therefore, the S.E.P. Package’s Processor Power would also include power dissipated by the AGTL+ termination resistors. The overall system chassis thermal design must comprehend the entire Processor Power. The Heatsink Design Target consists of only the processor core, which dissipates the majority of the thermal power.
Systems should design for the highest possible thermal power, even if a processor with a lower thermal dissipation is planned. The processor ’s heatslug is the attach location for all thermal solutions. The maximum and minimum cas e temperatures are also specif ied in Table 40. A thermal solution should be designed to ensure the temperature of the case never exceeds these specifications.

4.1.1 Thermal Diode

The Celeron processor incorporates an on-die diode that can be used to monitor the die temperature. A thermal sensor located on the motherboard or a standalone measurement kit may monitor the die temperature of the Intel Celeron processor for thermal management purposes.
Table 42 to Tabl e 44 provide the diode parameter and interface specifications.
Note: The reading of the thermal sensor connected to the thermal diode will not necessarily reflect the

This is due to inaccuracies in the thermal sensor, on­die temperature gradients between the location of the thermal diode and the hottest location on the die at a given point in time, 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 T

5.0 Mechanical Specifications

There are three package technologies which Celeron processors use. They are the S.E.P. Package, the PPGA package, and the FC-PGA/FC-PGA2 packages. The S.E.P. Package and FC-PGA/ FC-PGA2 packages contain the processor core and passive components, while the PPGA package does not have passive components.
The processor edge connector defined in this document is referred to as the “SC242 connector.” See the SC242 Design Guidelines (Order Number 243397) for further details on the edge connector.
The processor socket connector is defined in this document is referred to as the “370-pin socket.” See the 370-Pin Socket (PGA370) Design Guidelines (Ord er Number 244410 ) for furth er details on the socket.

5.1 S.E.P. Package

This section defines the mechanical specifications and signal definitions for the Celeron processor in the S.E.P. Package.

5.1.1 Materials Information

The Celeron processor requires a retention mechanism. This retention mechanism may require motherboard holes to be 0.159" diameter if low cost plastic fasteners are used to secure the retention mechanisms. The larger diameter holes are ne cessary to provide a r obust structural design that can shock and vibe testing. If captive nuts are used in place of the plas tic fastener s, then either the 0.159" or the 0.140" diameter holes will suffice as long as the attach mount is used.
Figure 19 with substrate dimensions is provided to aid in the design of a heatsink and clip. In Figure 20 all area on the secondary side of the substrate is zoned “keepout”, except for 25 mils
around the tooling holes and the top and side edges of the substrate.

NOTES:
1. Capacitors and resist ors may be placed on the pin-side of the FC-PGA package in the area defined by G1, G2, and G3. This area is a keepout zone for motherboard designers.
The bare processor die has mechanical load limits that should not be exceeded during heatsink assembly, mechanical stress testing, or standard drop and shipping conditions. The heatsink attach solution must not induce permanent stress into the processor substrate with the exception of a uniform load to maintain the heatsink to the proces sor thermal interfac e. The package dynamic an d static loading parameters are listed in Table 52.
For Table 52, the following apply:
1. It is not recommended to use any portion of the processor substrate as a mechanical reference or load bearing surface for thermal solutions.
2. Parameters assume uniformly applied loads
