Electrical Specifications

NOTES:

1. Unless otherwise noted, all specifications in this table are based on estimates and simulations or empirical data.

These specifications will be updated with characterized data from silicon measurements at a later date.

2. Adherence to the voltage specifications for the processor are required to ensure reliable processor operation.

3. Each processor is programmed with a maximum valid voltage identification value (VID) that is set at

manufacturing and can not 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.

These voltages are targets only. A variable voltage source should exist on systems in the event that a different

voltage is required. See Section 2.3 and Table 2 for more information.

5. The voltage specification requirements are measured across VCC_SENSE and VSS_SENSE lands at the 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 into the oscilloscope probe.

6. Refer to Table 5 and Figure 1 for the minimum, typical, and maximum VCC allowed for a given current. The

processor should not be subjected to any VCC and ICC combination wherein VCC exceeds VCC_MAX for a given

current.

7. ICC_MAX is specified at VCC_MAX

8. The current specified is also for AutoHALT State.

9. I

CC Stop-Grant is specified at V

CC_MAX.

10.The maximum instantaneous current the processor will draw while the thermal control circuit is active (as

indicated by the assertion of PROCHOT#) is the same as the maximum I

CC for the processor.

11.VTT must be provided via a separate voltage source and not be connected to VCC. This specification is measured

at the land.

12.Baseboard bandwidth is limited to 20 MHz.

13.This is maximum total current drawn from VTT plane by only the processor. This specification does not include

the current coming from RTT (through the signal line). Refer to the Voltage Regulator-Down (VRD) 10.1 Design

Guide For Desktop and Transportable LGA775 Socket to determine the total ITT drawn by the system.

14.This is a steady-state ITT current specification that is applicable when both VTT and VCC are high.

15.This is a power-up peak current specification that is applicable when VTT is high and VCC is low.
