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, 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.
