Intel Xeon 7130N LF80550KF0878M Data Sheet

Due to the voltage levels supported by other components in the TAP logic, Intel recommends that 
the Dual-Core Intel Xeon processor 7000 series be first in the TAP chain, followed by any other 
components within the system. Use of a translation buffer to connect to the rest of the chain is 
recommended unless one of the other components is capable of accepting an input of the 
appropriate voltage. Similar considerations must be made for TCK, TMS, TRST#, TDI, and TDO. 
Two copies of each signal may be required, each driving a different voltage level.

 specifies absolute maximum and minimum ratings. Within functional operation limits, 

functionality and long-term reliability can 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.

NOTES:
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 pins 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.
