PID: 30430 Rev 3.51 March 2006 AMD Athlon™ 64 Processor Power and Thermal Data Sheet

83AMD Turion™ 64 Mobile Technology

1. The VID_VDD voltage for Low Power Mobile parts corresponds to 0 load (0 Amp IDD) conditions for the

VID[4:0] requested VDD supply level. Refer to the AM D Functional Data Sheet, 754 Pin Package, order #31410,

for details.

2. The VDD_dc Typical Voltage is calculated using the following formula: VDD_dc Typ = VID_VDD – 1.83 mV/A

* IDD M ax. Refer to the AM D Functional Data Sheet, 754 Pin Package, order# 31410, for complete VDD

sp ecifications.

3. Thermal Design Power (TDP) for Low Power Mobile parts is measured under the conditions of Tdie Max, IDD

Max, and VDD=VDD_dc Typ, and include all power dissipated on-die from VDD, VDDIO, VLDT, VTT, and

VDDA. Contact your Field Application Engineer for more information on TDP specifications.

4. Assumes Tdie max, max P-state VDD_dc Typ +25 mV, clock divider set to 512.

5. Assumes 50°C, min P-state VID_VDD, clock divider set to 512.

6. Assumes 35°C, min P-state VID_VDD, clock divider set to 512, HyperTransport™ links disconnected, memory

in self-refresh mode, DDR SDRAM interface tri-stated except clocks and CKE pins.

7. Assumes 35°C, AltVID, clock divider set to 512, HyperTransport™ links disconnected, memory in self-refresh

mode, DDR SDRAM interface tri-stated except CKE pins. Not all sy stems are AltVID cap able. Refer to the

BIOS and Kernel Developer’s Guide for AMD Athlon™ 64 and AM D Opteron™ Processors, order# 26094 for

further details.

8. BIOS programs the AltVID setting into Function 3: Offset D8h. Not all systems are AltVID capable. Refer to the

BIOS and Kernel Developer’s Guide for AMD Athlon™ 64 and AM D Opteron™ Processors, order# 26094 for

further details.

9. 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.

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

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

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

13. Assumes VDDIO = 2.5 V and VTT = VDDIO / 2. Refer to the AM D Functional Data Sheet, 754 Pin Package,

order# 31410 for complete VDDIO and VTT power supply specifications.
