specifications equal to the FMB value in the foreseeable future. System designers 
should meet the FMB values to ensure their systems will be compatible with future 
processors.

 specifies absolute maximum and minimum ratings only, which lie outside the 

functional limits of the processor. Only within specified operation limits, can 
functionality and long-term reliability be expected.

At conditions outside functional operation condition limits, but within absolute 
maximum and minimum ratings, neither functionality nor long-term reliability can be 
expected. If a device is returned to conditions within functional operation limits after 
having been subjected to conditions outside these limits, but within the absolute 
maximum and minimum ratings, the device may be functional, but with its lifetime 
degraded depending on exposure to conditions exceeding the functional operation 
condition limits.

At conditions exceeding absolute maximum and minimum ratings, neither functionality 
nor long-term reliability can be expected. Moreover, if a device is subjected to these 
conditions for any length of time then, when returned to conditions within the 
functional operating condition limits, it will either not function or its reliability will be 
severely degraded.

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.

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
