28 / 82 page ![]() 28 Datasheet Electrical Specifications 2.12 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. Table 2-15. BSEL [1:0] and VID[5:0] DC Specifications Symbol Parameter Max Unit Notes1 NOTES: 1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
