Notes:
1. The V
CC_MIN
and V
CC_MAX
load lines represent static and transient limits.
2. This table is intended to aid in reading discrete points on Figure 2-15.
3. The load lines specify voltage limits at the die measured at the VCCCORESENSE and VSSCORESENSE pins.
Voltage regulation feedback for voltage regulator circuits must be taken from processor VCC and VSS pins.
Refer to the Ararat II Voltage Regulator Module Design Guide for socket load line guidelines and VR
implementation.
