Mobile Intel Pentium 4 Processor Supporting Hyper-Threading Technology on 90-nm Process Technology

Mobile Intel® Pentium® 4 Processor Supporting Hyper-Threading Technology on 90-nm Process Technology Datasheet 19

Electrical Specifications

NOTES:

1. For functional operation, all processor electrical, signal quality, mechanical and thermal specifications must

be satisfied.

2. Overshoot and undershoot voltage guidelines for input, output and I/O signals are outlined in Section 3.

Excessive overshoot or undershoot on any signal will likely result in permanent damage to the processor.

3. Storage temperature is applicable to storage conditions only. In this scenario, the processor must not receive

a clock, and no lands can be connected to a voltage bias. Storage within these limits will not affect the long-

term reliability of the device. For functional operation, please refer to the processor case temperature

specifications.

4. This rating applies to the processor and does not include any tray or packaging.

5. Contact Intel for storage requirements in excess of one year.

2.10 Processor DC Specifications

The processor DC specifications in this section are defined at the processor core silicon and

not at the package pins unless noted otherwise. See Section 4 for the pin signal definitions and

signal pin assignments. Most of the signals on the processor front side bus are in the GTL+ signal

group. The DC specifications for these signals are listed in Table 2-10.

Previously, legacy signals and Test Access Port (TAP) signals to the processor used low-voltage

CMOS buffer types. However, these interfaces now follow DC specifications similar to GTL+. The

DC specifications for these signal groups are listed in Table 2-11 and Table 2-12.

Table 2-8 through Table 2-16 list the DC specifications for the processor and 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.

2.10.1 Fixed Mobile Solution (FMS)

The FMS guidelines are estimates of the maximum values the mobile processor will have over

certain time periods. The values are only estimates and actual specifications for future processors

may differ. The processor may or may not have specifications equal to the FMS value in the

foreseeable future. System designers should meet the FMS values to ensure their systems will be

compatible with future releases of the mobile processor.
