Overshoot Specifications
The processor can tolerate short transient overshoot events where V
CC
exceeds the VID
voltage when transitioning from a high-to-low current load condition. This overshoot
cannot exceed VID + V
OS_MAX
(V
OS_MAX
is the maximum allowable overshoot above
VID). These specifications apply to the processor die voltage as measured across the
VCC_SENSE and VSS_SENSE lands.
Notes:
1. V
OS
is the measured overshoot voltage.
2. T
OS
is the measured time duration above VID.
