Notes:
1. Unless otherwise noted, all specifications in this table are based on estimates and simulations or empirical data. These
specifications will be updated with characterized data from silicon measurements at a later date.
2. Long term reliability cannot be assured in conditions above or below Max/Min functional limits.
3. The voltage specification requirements are measured across Vcc

as near as possible to the processor with an oscilloscope set to 100-MHz bandwidth, 1.5 pF maximum probe
capacitance, and 1 M minimum impedance. The maximum length of ground wire on the probe should be less than 5 mm.
Ensure external noise from the system is not coupled into the oscilloscope probe.
4. OS occurs during power on only, not during normal operation
5. For Voltage less than 1V, TOB will be 50 mV.
6. For share VR options between VCCOPC and VCCEOPIO refer to Intel Design Guidelines.
