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 Chapter 4 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 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 2-15 list the DC specifications for the Celeron D 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.

NOTES:

Individual processor VID values may be calibrated during manufacturing such that two devices at the same

speed may have different VID settings.

These voltages are targets only. A variable voltage source should exist on systems in the event that a differ-

ent voltage is required. See Section 2.4 and Table 2-2 for more information.
