Notes:
1. Unless otherwise noted, all specifications in this table apply to all processors. These specifications are based on pre-silicon
characterization.
2. Individual processor VID values may be calibrated during manufacturing such that two devices at the same speed may have
different settings.
3. These voltages are targets only. A variable voltage source should exist on systems in the event that a different voltage is
required.
4. The V
CC
voltage specification requirements are measured across the remote sense pin pairs (VCC_SENSE and
VSS_VCC_SENSE) on the processor package. Voltage measurement should be taken with a DC to 100 MHz bandwidth
oscilloscope limit (or DC to 20 MHz for older model oscilloscopes), using a 1.5 pF maximum probe capacitance, and 1 M
minimum impedance. The maximum length of the ground wire on the probe should be less than 5 mm to ensure external
noise from the system is not coupled in the scope probe.
5. The V
TTA,
and V
TTD
voltage specification requirements are measured across the remote sense pin pairs (VTTD_SENSE and
VSS_VTTD_SENSE) on the processor package. Voltage measurement should be taken with a DC to 100 MHz bandwidth
oscilloscope limit (or DC to 20MHz for older model oscilloscopes), using a 1.5 pF maximum probe capacitance, and 1 M
minimum impedance. The maximum length of the ground wire on the probe should be less than 5 mm to ensure external
noise from the system is not coupled in the scope probe.
6. The V
SA
voltage specification requirements are measured across the remote sense pin pairs (VSA_SENSE and
VSS_VSA_SENSE) on the processor package. Voltage measurement should be taken with a DC to 100 MHz bandwidth
oscilloscope limit (or DC to 20 MHz for older model oscilloscopes), using a 1.5 pF maximum probe capacitance, and 1 M
minimum impedance. The maximum length of the ground wire on the probe should be less than 5 mm to ensure external
noise from the system is not coupled in the scope probe.
7. The processor should not be subjected to any static V
CC
level that exceeds the V
CC_MAX
associated with any particular current.
Failure to adhere to this specification can shorten processor lifetime.
8. Minimum V
CC
and maximum I
CC
are specified at the maximum processor case temperature (T
CASE
). I
CC_MAX
is specified at the
relative V
CC_MAX
point on the V
CC
load line. The processor is capable of drawing I
CC_MAX
for up to 5 seconds.
9. The processor should not be subjected to any static V
TTA,
V
TTD
level that exceeds the V
TT_MAX
associated with any particular
current. Failure to adhere to this specification can shorten processor lifetime.
10. This specification represents the V
CC
reduction or V
CC
increase due to each VID transition, see Section 7.1.8.3.
11. Baseboard bandwidth is limited to 20 MHz.
12. N/A
13. DC + AC + Ripple = Total Tolerance
14. For Power State Functions see Section 7.1.8.3.5.
15. V

does not have a loadline, the output voltage is expected to be the VID value.

vias close to the socket and measure with a DC to 100MHz bandwidth oscilloscope limit (or DC to 20 MHz
for older model oscilloscopes), using 1.5 pF maximum probe capacitance, and 1M minimum impedance. The maximum
length of the ground wire on the probe should be less than 5 mm to ensure external noise from the system is not coupled in
the scope probe.
18. V

has a Vboot setting of 0.0V and is not included in the PWRGOOD indication.
19. V

has a Vboot setting of 0.9V.
