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.

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 specifications.

4.

This rating applies to the processor and does not include any tray or packaging.

5.

Failure to adhere to this specification can affect the long-term reliability of the processor.

are specified in 

. The DC specifications for the AGTL+ signals are listed in 

. Legacy signals and Test Access Port (TAP) signals follow DC specifications 

similar to GTL+. The DC specifications for the PWRGOOD input and TAP signal group 

 through 

 list the DC specifications for the processor and are valid 

only while meeting specifications for case temperature (T

 as specified in 

), clock frequency, and input voltages. Care should be taken to 

read all notes associated with each parameter.
