NOTES:
1. Each processor is programmed with a maximum valid voltage identification value
(VID), which is set at manufacturing and cannot be altered. Individual maximum VID
values are calibrated during manufacturing such that two processors at the same
frequency may have different settings within the VID range. Note that this differs from
the VID employed by the processor during a power management event (Thermal
Monitor 2, Enhanced Intel SpeedStep technology, or Enhanced Halt State). Typical
AVID range is 0.75 V to 0.85 V.
2. The voltage specifications are assumed to be measured across VCC_SENSE and
VSS_SENSE pins at 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 in the scope probe.

tolerance is shown in Figure 6 and Figure 7.
7. Based on simulations and averaged over the duration of any change in current.

CC
. Not 100% tested.
8. This is a power-up peak current specification, which is applicable when V
CCP
is high and
V
CC_CORE
is low.
9. This is a steady-state I
CC
current specification, which is applicable when both V
CCP
and
V
CC_CORE
are high.
10. The V
CC
maximum supported by the process is 1.1 V but the parameter can change
(burn in voltage is higher).
11. Unless otherwise noted, all specifications in this table are based on estimates and
simulations or empirical data. These specifications will be updated with characterized
data from silicon measurements at a later date.
12. V
CCP
and V
CCPC6
must always be powered on to 1.05 V ±5% on all power states.
13. The V
CC
power supply needs to be set to 0.3 to 0.4 V during C6 power state.
14. The Intel Atom processor Z515 enables Intel® Burst Performance Technology (Intel®
BPT).
