Cache Voltage Identification
The Cache Voltage Identification (CVID) lands, VID_VCCCACHE[5:0], supply the
voltage for VCCCACHE, the L3 cache voltage for the processor. The VID_VCCCACHE
specification for the processor is supported by the Ararat 170 Watt Voltage Regulator
Design Guide. The voltage set by the VID_VCCCACHE pins is the maximum VCCCACHE
voltage allowed by the processor.

Design Guide. The voltage set by the VID_VCCCACHE pins is the maximum VCCCACHE
voltage allowed by the processor.
Individual processor CVID values may be calibrated during manufacturing such that
two devices at the same core speed may have different default VID_VCCCACHE
settings.
two devices at the same core speed may have different default VID_VCCCACHE
settings.
The processor uses six voltage identification lands (VID_VCCCACHE[5:0]) to support
automatic selection of power supply voltages.

specifies the voltage level
corresponding to the state of VID_VCCCACHE[5:0]. A ‘1’ in this table refers to a high
voltage level and a ‘0’ refers to a low voltage level. See the Ararat 170 Watt Voltage
Regulator Design Guide for more details.
