Intel X5460 AT80574KJ087N Data Sheet

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.

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.

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

 for the Quad-Core Intel® Xeon® 

Processor 5400 Series land listings and 

 for signal definitions. Voltage and 

current specifications are detailed in 

. For platform planning refer to 

, which provides V

CC

 static and transient tolerances. This 

same information is presented graphically in 

 and 

The FSB clock signal group is detailed in 

. BSEL[2:0] and VID[6:1] signals 

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 
are listed in 

 through 

 list the DC specifications for the processor and are valid 

only while meeting specifications for case temperature (T

CASE

 as specified in 

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

read all notes associated with each parameter. 

The Flexible Motherboard (FMB) guidelines are estimates of the maximum values the 
Quad-Core Intel® Xeon® Processor 5400 Series will have over certain time periods. 
The values are only estimates and actual specifications for future processors may differ. 
Processors may or may not have 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 Quad-Core Intel® Xeon® Processor 5400 
Series.
