Intel E5645 AT80614003597AC User Manual

31

Although the processor contains protective circuitry to resist damage from static 
electric discharge, precautions should always be taken to avoid high static voltages or 
electric fields.

1.

For functional operation, all processor electrical, signal quality, mechanical and thermal specifications must 

be satisfied.

2.

Overshoot and undershoot voltage guidelines for input, output, and I/O signals are outlined in 

. 

Excessive overshoot or undershoot on any signal will likely result in permanent damage to the processor.

3.

V

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, please refer to the processor case 

temperature specification.

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

DC specifications are defined at the processor pads, unless otherwise noted. 
DC specifications are only valid while meeting specifications for case temperature 
(T

CASE

 specified in 

), clock frequency, and input 

voltages. Care should be taken to read all notes associated with each specification.
