Electrical Specifications
NOTES:
1. The V
and V
load lines represent static and transient limits.
2. Refer to
Table 2-9
for processor VID information for V
.
3. The load lines specify voltage limits at the die measured at the V
and V
pins. Voltage
regulation feedback for voltage regulator circuits must also be taken from processor V
CCSENSE
and
V
SSSENSE
pins.

and V
CACHE
Overshoot Specification
The processor can tolerate short transient overshoot events where V
CC
exceeds the VID voltage or
where V
CACHE
exceeds the CVID voltage when transitioning from a high-to-low current load
condition. This overshoot cannot exceed VID + V
OS_MAX,
or CVID + V
OS_MAX
. (V
OS_MAX
is the
maximum allowable overshoot above VID or CVID). These specifications apply to the processor
die voltage as measured across the V
CCSENSE
and V
SSSENSE
pins for Vcc, and V
CC_CACHE_SENSE
and V
SS_CACHE_SENSE
pins for CVID.
