Voltage Identification
The VID specification for Celeron processor on 0.13 micron process is supported by the Intel
Pentium 4 Processor VR-Down Design Guidelines. The voltage set by the VID pins is the
maximum voltage allowed by 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 Celeron processor on 0.13 micron process uses five voltage identification pins, VID[4:0], to
support automatic selection of power supply voltages. The VID pins for the Celeron processor on
0.13 micron process are open drain outputs driven by the processor VID circuitry. The VID signals
rely on pull-up resistors tied to a 3.3V (max) supply to set the signal to a logic high level. These
pull-up resistors may be either external logic on the motherboard, or internal to the Voltage
Regulator. Table 3 specifies the voltage levels corresponding to the states of VID[4:0]. A 1 in this
table refers to a high voltage level, and a 0 refers to low voltage level. The definition provided in
Table 3 is not related in any way to previous P6 processors or VRs, but is compatible with the
Pentium 4 processor in the 478-pin package. If the processor socket is empty (VID[4:0] = 11111) or
the voltage regulation circuit cannot supply the voltage that is requested, it must disable itself. See
the Intel Pentium 4 Processor VR-Down Design Guidelines for more details.
Power source characteristics must be stable whenever the supply to the voltage regulator is stable.
Refer to the Figure 14 for timing details of the power up sequence. Also refer to the appropriate
platform design guide listed in Table 1 for implementation details.
The Voltage Identification circuit requires an independent 1.2V supply. This voltage must be routed
to the processor VCCVID pin. Table 2 and Figure 1 describe the voltage and current requirements
of the VCCVID pin.
NOTES:
1. This specification applies to both static and transient components. The rising edge of VCCVID must be
monotonic from 0 to 1.1 V. See Figure 1 for current requirements. In this case, monotonic is defined as
continuously increasing with less than 50 mV of peak to peak noise for any width greater than 2 ns
superimposed on the rising edge.
