 Processor 9300 Series processor supplies top side VID signal pins 

to the Arafat Voltage Regulator Module, as shown in 

The Intel

 Processor 9500 Series implements a Serial VID BUS that is used 

to transfer power management information between the microprocessor and the five 
output voltages. Voltage levels are compliant to the VR12.0 1V TTL signaling 
requirements and are shown in 

.

2. With input leakage current measured at the pin with 0V and with 1.1 V supplied to the pin. System designers 

are advised to check the tolerance of their voltage regulator solutions to ensure a voltage of 1.1 V at the pin.
