Electrical Specifications

2.10 Maximum Ratings

Table 2-5 lists the processor’s maximum environmental stress ratings. The processor should not

receive a clock while subjected to these conditions. Functional operating parameters are listed in

the DC tables. Extended exposure to the maximum ratings may affect device reliability.

Furthermore, although the processor contains protective circuitry to resist damage from Electro

Static Discharge (ESD), one should always take precautions to avoid high static voltages or electric

fields.

NOTES:

1. This rating applies to any processor pin.

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

2.11 Processor DC Specifications

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

noted otherwise. See Chapter 4 for the pin signal definitions and signal pin assignments. Most of

the signals on the processor system bus are in the AGTL+ signal group. The DC specifications for

these signals are listed in Table 2-9.

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 2-10.

Table 2-6 through Table 2-10 list the DC specifications for the Pentium 4 processor on 0.13 micron

process, 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.

Processors with multiple VID have I

CC_MAX

of the highest VID for the specified frequency. For

example, for processors through 2.80 GHz, the I

CC_MAX

would be the one at VID=1.525 V.
