Electrical Specifications

2.11.3 V

Overshoot Specification

Processors can tolerate short transient overshoot events where V

exceeds the VID

voltage when transitioning from a high-to-low current load condition. This overshoot

cannot exceed VID + 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 pins and across the VCC_SENSE2 and VSS_SENSE2 pins.
