VCC Overshoot Specification

The Celeron D processor can tolerate short transient overshoot events where VCC exceeds the VID

voltage when transitioning from a high to low current load condition. This overshoot cannot exceed

VID + VOS_MAX (VOS_MAX is the maximum allowable overshoot voltage). The time duration of

the overshoot event must not exceed TOS_MAX (TOS_MAX is the maximum allowable time duration

above VID). These specifications apply to the processor die voltage as measured across the

VCC_SENSE and VSS_SENSE pins.
