VOLTAGE REGULATOR MODULE

FOR INTEL ADVANCED PROCESSORS

PRELIMINARY - November 3, 1997

652 MITCHELL ROAD NEWBURY PARK CA 91320

VOLTAGE REGULATOR MODULE CONNECTOR PIN REFERENCE

Pin Name

Pin Function

PWRGD

Power Good: When the output voltage is not within specifications (nominal or selected voltage +

7%) this signal will be in the low state. The PWRGD signal will change to the proper state within

5ms of the output coming into or going out of specification.

OUTEN

Output Enable: A low state disables the output voltage. When disabled, the PWRGD signal shall

be in the low state.

System Ground

VID[0:4]

Voltage Identification: The module will accept five open collector signals, used to indicate the

voltage required by the processor, as defined by Intel
