Intel Pentium 4 Processor in the 478-PinPackage at 1.40 GHz, 1.50 GHz, 1.60 GHz, 1.70 GHz, 1.80 GHz, 1.90 GHz, and 2GHz
Electrical Specifications
20 Datasheet
NOTES:
1. Unless otherwise noted, all specifications in this table are based on estimates and simulations, not empirical
data. These specifications will be updated with characterized data from silicon measurements at a later date.
2. These voltages are targets only. A variable voltage source should exist on systems in the event that a
different voltage is required. See Section 2.4 and Table 2 for more information.
3. The voltage specification requirements are measured across V
CC_SENSE
and V
SS_SENSE
pins at the socket with
a 100 MHz bandwidth oscilloscope, 1.5 pF maximum probe capacitance, and 1 MΩ minimum impedance.
The maximum length of ground wire on the probe should be less than 5 mm. Ensure external noise from the
system is not coupled into the scope probe.
4. Refer to Table 7 and Figure 3 for the minimum, typical, and maximum V
CC
allowed for a given current. The
processor should not be subjected to any V
CC
and I
CC
combination wherein V
CC
exceeds V
CC_MAX
for a given
current. Moreover, V
CC
should never exceed the VID voltage. Failure to adhere to this specification can
shorten the processor lifetime.
5. V
CC_MIN
is defined at I
CC_MAX
.
6. The current specified is also for AutoHALT State.
7. The maximum instantaneous current the processor will draw while the thermal control circuit is active as
indicated by the assertion of PROCHOT# is the same as the maximum I
CC
for the processor.
8. I
CC
Stop-Grant and I
CC
Sleep are specified at V
CC_MAX.
9. These specifications apply to processors with a VID setting of 1.75 V.
10.Some processors at this frequency have special specifications. These parts are distinguishable by their S-
Spec number. Refer to the Supplement to the Intel® Pentium® 4 Processor Specification Update for the
detailed specifications and for the specific S-Specs associated with these differing specifications.
