Electrical Specifications
Notes:
1. For functional operation, all processor electrical, signal quality, mechanical and thermal specifications
must be satisfied.
2. Excessive overshoot or undershoot on any signal will likely result in permanent damage to the
processor.
3. V
TTA
and V
TTD
should be derived from the same voltage regulator (VR).
4. ± 5% tolerance.
5. Storage temperature is applicable to storage conditions only. In this scenario, the processor must not
receive a clock, and no lands can be connected to a voltage bias. Storage within these limits will not
affect the long-term reliability of the device. For functional operation, see the processor case
temperature specifications.
6. This rating applies to the processor and does not include any tray or packaging.
7. Failure to adhere to this specification can affect the long-term reliability of the processor.
8. See the Intel

13.6 Processor DC Specifications
Note: All electrical specifications are pre-silicon estimates and are subject to
change.
Note: DC specifications are defined at the processor pads, unless otherwise noted.
Note: For available SKUs, see Table 1, “Available SKUs”.
DC specifications are only valid while meeting specifications for case temperature

Design Guide), clock frequency, and input voltages. Care should be taken to read all
notes associated with each specification.
This section is divided into groups of signals that have similar characteristics and buffer
types. There are eight sections in total, divided as follows:
