Intel Core Duo T2500 LF80539GF0412M User Manual

Datasheet

NOTES:
1.

Each processor is programmed with a maximum valid voltage identification value (VID), which is set at 

manufacturing and cannot be altered. Individual maximum VID values are calibrated during manufacturing 

such that two processors at the same frequency may have different settings within the VID range. Note 

that this differs from the VID employed by the processor during a power management event (Intel Thermal 

Monitor 2, Enhanced Intel SpeedStep Technology, or C1E). 

2.

The voltage specifications are assumed to be measured across V

CCSENSE

 and V

SSSENSE 

pins at socket with a 

100-MHz bandwidth oscilloscope, 1.5-pF maximum probe capacitance, and 1-MΩ minimum impedance. 
The maximum length of ground wire on the probe should be less than 5 mm. Ensure external noise from 
the system is not coupled in the scope probe. 

3.

Specified at 100°C Tj. 

4.

Specified at the VID voltage.

5.

The I

CCDES

(max) specification of 36 A comprehends only Intel Core Duo processor SV HFM frequencies. 

Platforms should be designed to 44 A to be compatible with next generation processor.

6.

Based on simulations and averaged over the duration of any change in current. Specified by design/
characterization at nominal V

CC

. Not 100% tested.

7.

Measured at the bulk capacitors on the motherboard.

9.

This is a steady-state I

CCP

 current specification, which is applicable when both V

CCP

 and V

CC

 core are high.

10.

This is a power-up peak current specification, which is applicable when V

CCP

 is high and V

CC

 core is low. 

11.

Specified at the nominal V

CC

.

12.

If a given Operating Systems C-State model is not based on the use of MWAIT or I/O Redirection, the 
processor Deeper Sleep VID will be same as LFM VID.

13.

T2300E does not support Intel Virtualization Technology.
