AMD Athlon™ 64 Processor Power and Thermal Data Sheet

AMD Sempron™ Processor

1. Tcase max is the maximum case temperature specification which is a physical value in degrees Celsius. This value

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

THERM TRIP Status Register in the BIOS and Kernel Developer’s Guide for AMD 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

appropriate functional data sheet, and the THERM TRIP Status Register in the BIOS and Kernel Developer’s

Guide for AMD Athlon™ 64 and AMD 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 Max, 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 supply specifications.
