Electrical Specifications

Voltage Identification and Power Sequencing
The voltage set by the VID pins is the nominal/typical voltage setting for the processor. A
minimum voltage is provided in Table 7 and changes with frequency. This allows processors
running at a higher frequency to have a relaxed minimum voltage specification. The specifications
have been set such that one voltage regulator can work with all supported frequencies.
The mobile Celeron processor uses five voltage identification pins, VID[4:0], to support automatic
selection of power supply voltages. The VID pins for the mobile Celeron processor are open drain
outputs driven by the processor VID circuitry. Table 3 specifies the voltage level corresponding to
the state of VID[4:0]. A “1” in this table refers to a high-voltage level and a “0” refers to low-
voltage level.
Power source characteristics must be stable whenever the supply to the voltage regulator is stable.
Refer to Figure 15 for timing details of the power up sequence. Also refer to Mobile Intel
Pentium 4 Processor-M and Intel 845MP/845MZ Chipset Platform Design Guide for
implementation details.
Mobile Celeron processor’s Voltage Identification circuit requires an independent 1.2 V supply.
This voltage must be routed to the processor VCCVID pin. Figure 1 shows the voltage and current
requirements of the VCCVID pin.
