Electrical Specifications
11. Minimum VCC and maximum ICC are specified at the maximum processor case temperature (TCASE)
shown in
12. This specification refers to the total reduction of the load line due to VID transitions below the specified
VID.
13. Individual processor VID values may be calibrated during manufacturing such that two devices at the same
frequency may have different VID settings.
14. Baseboard bandwidth is limited to 20 MHz.
15. I
CC_TDC
is the sustained (DC equivalent) current that the processor is capable of drawing indefinitely and
should be used for the voltage regulator temperature assessment. The voltage regulator is responsible for
monitoring its temperature and asserting the necessary signal to inform the processor of a thermal
excursion. Please see the applicable design guidelines for further details. The processor is capable of
drawing I
CC_TDC
indefinitely. Refer to
and
for further details on the average processor
current draw over various time durations. This parameter is based on design characterization and is not
tested.
16. This specification is per-processor. This is a steady-state I
TT
current specification, which is applicable when
both V
TT
and V
CC
are high. This parameter is based on design characterization and is not tested. Please
refer to the
I
TT
Analysis of System Bus Components - Bensley Platform Whitepaper
for platform
implementation guidance.
17. I
CC
_
VTTOUT
is specified at 1.2 V.
18.I
CC_RESET
is specified while PWRGOOD and RESET# are asserted.
19. This specification is per-processor. This is a power-up peak current specification, which is applicable when
V
TT
is powered up and V
CC
is not. This parameter is based on design characterization and is not tested.
