Electrical Specifications
2 Electrical Specifications
The Intel Xeon Processor E7-8800/4800/2800 Product Families package pin electrical
specification is outlined in this section. The Intel Xeon E7-8800/4800/2800 Product
Families processor interfaces to other components of the platform via connections
established at Intel® QuickPath Interconnect (Intel® QPI), Intel® Scalable Memory
Interconnect (Intel® SMI), system management interfaces, power, reset, clock and
debug signals. The electrical characteristics of all such signals, categorized per the I/O
type, are documented in this section.
2.1
Processor Maximum Ratings
Table 2-1 specifies absolute maximum and minimum ratings. Within operational
maximum and minimum limits, functionality and long-term reliability can be expected.
Processor maximum ratings outlined in Table 2-1 are applicable for all Intel Xeon E7-
8800/4800/2800 Product Families processor SKUs.
At conditions outside operational maximum ratings, but within absolute maximum and
minimum ratings, neither functionality nor long-term reliability can be expected. If a
device is returned to conditions within operational maximum and minimum ratings
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.
