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.

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 ICC_MAX of the highest VID for the specified frequency. For
example, for processors through 2.80 GHz, the ICC_MAX would be the one at VID=1.525 V.
