SM_DRAMPWROK

SM_DRAMPWROK Processor Input: Connects to PCH

DRAMPWROK.

Asynchronous

CMOS

UNCOREPWRGOOD

The processor requires this input signal to be a clean indication

that the V

CCSA

, V

CCIO

, V

AXG

, and V

DDQ

, power supplies are

stable and within specifications. This requirement applies

regardless of the S-state of the processor. 'Clean' implies that

the signal will remain low (capable of sinking leakage current),

without glitches, from the time that the power supplies are

turned on until they come within specification. The signal must

then transition monotonically to a high state. This is connected

to the PCH PROCPWRGD signal.

Asynchronous

CMOS

SKTOCC#

SKTOCC# (Socket Occupied) : This signal is pulled down

directly (0 Ohms) on the processor package to the ground.

There is no connection to the processor silicon for this signal.

System board designers may use this signal to determine if the

processor is present.

PROC_SEL

Processor Select: This signal is an output that indicates if the

processor used is 2nd Generation Intel

Core™ processor family

desktop, Intel

Pentium

processor family desktop, Intel

Celeron

processor family desktop or Desktop 3rd Generation

Intel

Core™ processor family, Desktop Intel

For 2nd Generation Intel

Core™ processor family desktop,

Intel

Pentium

processor family desktop, Intel

Celeron

processor family desktop, the output will be high.
For Desktop 3rd Generation Intel

Core™ processor family,

Desktop Intel

Pentium

processor family, Desktop Intel

Celeron

processor family, the output will be low.

VCCIO_SEL

Voltage selection for VCCIO: This output signal was initially

intended to select the I/O voltage depending on the processor

being used.
Since the V

CCIO

voltage is the same for 2nd Generation Intel

Core™ processor family desktop, Intel

Pentium

Celeron

processor family desktop and

Desktop 3rd Generation Intel

Intel

Pentium

processor family, Desktop Intel

Celeron

processor family, the usage of this pin was changed as follows:
The pin is configured on the package to be same as 2nd

Generation Intel

Core™ processor family desktop, Intel

Pentium

processor family desktop, Intel

Celeron

processor

family desktop . This pin must be pulled high on the

motherboard, when using a dual rail voltage regulator.
