94AMD Athlon™ 64 X2 Dual Core Processor

1. Tcase max is the maximum case temperature sp ecification which is a phy sical value in degrees Celsius. This value

is programmed into Rev D and later processors. Refer to the appropriate functional data sheet, and the

THERMTRIP Status Register in the BIOS and Kernel Developer’s Guide for AM D Athlon™ 64 and

AM D Opteron™ Processors, order# 26094.

2. Tcontrol max (maximum control temperature) is a non physical temperature on an arbitrary scale that can be used

for system thermal management policies. Tcontrol max represents the value at which the processor has reached

Tcase max when measuring the thermal diode with a dual sourcing current temperature sensor. Refer to the

ap prop riate functional data sheet, and the THERM TRIP Status Register in the BIOS and Kernel Develop er’s

Guide for AMD Athlon™ 64 and AM D Opteron™ Processors, order# 26094.

3. The VID_VDD voltage is the VID[4:0] requested VDD supply level. Refer to the appropriate functional data

sheet for details.

4. Thermal Design Power (TDP) is measured under the conditions of Tcase M ax, IDD M ax, and VDD=VID_VDD,

and include all power dissipated on-die from VDD, VDDIO, VLDT, VTT, and VDDA.

5. Assumes Tcase max, max P-state VID_VDD, clock divider set to 32.

6. Assumes 50°C, min P-state VID_VDD, clock divider set to 32.

7. Assumes 35°C, VDD, VDDA, and VLDT supplies are off, VDDIO and VTT are powered, memory in self-

refresh mode and DDR SDRAM interface tri-stated except CKE pins. Refer to the appropriate functional data

sheet for complete VDDIO and VTT power supply specifications.

8. Thermal Design Power dissipated by the processor VDDIO, VTT, VLDT, and VDDA power planes only.

9. Thermal Design Power dissipated by the processor VDDIO and VTT power planes only.

10. Refer to the AM D Athlon™ 64 Processor Desktop Power Roadmap, order #26882, for IDD M ax and Thermal

Design Power requirements for future processor revisions.

11. Implementation of this P-state is optional in BIOS.

12. Assumes VDDIO = 2.6 V and VTT = VDDIO / 2. Refer to the appropriate functional data sheet for complete

VDDIO and VTT power sup p ly sp ecifications.

13. Tcase max is programmed during device manufacturing with part-specific values for Rev E and later processors,

and can be any valid Tcase max value in the range specified for the corresponding OPN.

14 Thermal Design Power (TDP) and IDD max for Rev E and later p rocessors are the limits at the highest Tcase max

in the specified range for the corresponding OPN. Products will conform to the TDP and IDD M ax limits at all

valid voltages. The relationship of Tcase max and Thermal Profile to TDP for a specific device is defined in

15 Thermal Design Power (TDP) specifications for dual core processors assume equivalent P-states (Voltage and

frequency) and equivalent Tcase conditions for both cores. Refer to the BIOS and Kernel Developer’s Guide for

AM D Athlon™ 64 and AM D Opteron™ Processors, order# 26094, for details on P-state operation for dual core

processors.

16 IDDC1 specifications for dual core processors assume equivalent Voltage, clock divisor, and Tcase conditions for

both cores.
