Electrical Specifications
15.
This is maximum total current drawn from V
TT
 plane by only the processor. This specification does not include the
current coming from R
TT
 (through the signal line). Refer to the 
Voltage Regulator-Down (VRD) 10.1 Design Guide For
Desktop and Transportable LGA775 Socket
 to determine the total I
TT
 drawn by the system. 
16.This is a steady-state I
TT
 current specification, which is applicable when both V
TT
 and V
CC
 are high.
17.This is a power-up peak current specification, which is applicable when V
TT
 is high and V
CC
 is low.

NOTES:
1.
The loadline specification includes both static and transient limits except for overshoot allowed
as shown in 
.
2.
This table is intended to aid in reading discrete points on 
.
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 be taken from processor
VCC and VSS lands. Refer to the 
Voltage Regulator-Down (VRD) 10.1 Design Guide For Desktop and
Transportable LGA775 Socket
 for socket loadline guidelines and VR implementation details.
4. Adherence to this loadline specification for the processor is required to ensure reliable processor operation.
