Electrical Specifications
2.10 Maximum Ratings
Table 6 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 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 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 (pads) unless
noted otherwise. See Chapter 5 for the pin signal definitions and signal pin assignments. Most of
the signals on the processor FSB are in the GTL+ signal group. The DC specifications for these
signals are listed in Table 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 11 and Table 12.
Table 7 through Table 14 list the DC specifications for the mobile Intel Pentium 4 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.
2.11.1 Fixed Mobile Solution (FMS)
The FMS guidelines are estimates of the maximum values the mobile Intel Pentium 4 processor
will have over certain time periods. The values are only estimates and actual specifications for
future processors may differ. The mobile Intel Pentium 4 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 Intel
Pentium 4 processor.
