Intel® Xeon® Processors 5500 Series Electrical Specifications
Notes:
1.
When the “11111111” VID pattern is observed, or when the SKTOCC# pin is high, the voltage regulator
output should be disabled.
2.
Shading denotes the expected VID range of the Intel Xeon Processor 5500 Series.
3.
The VID range includes VID transitions that may be initiated by thermal events, Extended HALT state
transitions (see
), higher C-States (see
) or Enhanced Intel SpeedStep
®
Technology
transitions (see
). The Extended HALT state must be enabled for the processor to
remain within its specifications
4.
Once the VRM/EVRD is operating after power-up, if either the Output Enable signal is de-asserted or a
specific VID off code is received, the VRM/EVRD must turn off its output (the output should go to high
impedance) within 500 ms and latch off until power is cycled.
2.1.7.3.1
Power-On Configuration (POC) Logic
VID[7:0] signals also serve a second function. During power-up, Power-On
Configuration POC[7:0] functionality is multiplexed onto these signals via 1-5 kΩ pull-
Configuration POC[7:0] functionality is multiplexed onto these signals via 1-5 kΩ pull-
up or pull down resistors located on the baseboard. These values provide voltage
regulator keying (VID[7]), inform the processor of the platforms power delivery
capabilities (MSID[2:0]), and program the gain applied to the ISENSE input
(CSC[2:0]).
