.
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.
3. V
TTA
and V
TTD
should be derived from the same VR.
2.11 Processor DC Specifications
The processor DC specifications in this section are defined at the processor
pads, unless noted otherwise. See Chapter 4 for the processor land listings and
Chapter 5 for signal definitions. Voltage and current specifications are detailed in Tabl e
2-7. For platform planning, refer to Table 2-8, which provides V
CC
static and transient
tolerances. This same information is presented graphically in Figure 2-3.
The DC specifications for the DDR3 signals are listed in Table 2-11. Control Sideband
and Test Access Port (TAP) are listed in Table 2-12 through Table 2-15.
Table 2-7 through Table 2-15 list the DC specifications for the processor and are valid
only while meeting specifications for case temperature (T
CASE
as specified in Chapter 6,
“Thermal Specifications”), clock frequency, and input voltages. Care should be taken to
read all notes associated with each parameter.
