Datasheet 

.

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.

V

TTA

 and V

TTD

 should be derived from the same VR.

The processor DC specifications in this section are defined at the processor 
pads, unless noted otherwise. See 

 for the processor land listings and 

 for signal definitions. Voltage and current specifications are detailed in 

. For platform planning, refer to

 static and transient 

tolerances. This same information is presented graphically in 

The DC specifications for the DDR3 signals are listed in

 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.
