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, 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.

Notes:
1. Unless otherwise noted, all specifications in this table are based on estimates and simulations or empirical data. These
specifications will be updated with characterized data from silicon measurements at a later date.
2. Adherence to the voltage specifications for the processor are required to ensure reliable processor operation.
