Notes:
1. The V
CC_MIN
and V
CC_MAX
loadlines represent static and transient limits. See Section 13.6.1 for V
CC
overshoot specifications.
2. See Table 163 for V
CC
Static and Transient Tolerance.
3. The loadlines specify voltage limits at the die measured at the VCC_SENSE and VSS_SENSE lands.
Voltage regulation feedback for voltage regulator circuits must also be taken from processor
VCC_SENSE and VSS_SENSE lands. See the Voltage Regulator Module (VRM) and Enterprise Voltage
Regulator Down (EVRD) 11.1 Design Guidelines, Revision 1.5 for socket loadline guidelines and
regulator implementation. See the appropriate platform design guide for further details on regulator
and decoupling implementations.
4. Processor core current (I
CC
) ranges are valid up to I
CC_MAX
of the processor SKU as defined in
Table 162, “Voltage and Current Specifications”.
