Processor DC Specifications
The processor DC specifications in this section are defined at the processor core silicon and
not at the package lands unless noted otherwise. See

Previously, legacy signals and Test Access Port (TAP) signals to the processor used low-voltage
CMOS buffer types. However, these interfaces now follow DC specifications similar to GTL+. The

MSR_PLATFORM_BRV bit 18 is a Platform Requirement Bit (PRB) that indicates whether the
processor requires a 775_VR_CONFIG_04B (PRB = 1) or 775_VR_CONFIG_04A (PRB = 0)
platform.

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.

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.
