Notes:
1. ICC_CORE_TDC is the sustained (DC equivalent) current that the processor core is capable of drawing indefinitely and should be
used for the Ararat voltage regulator temperature assessment. The Ararat voltage regulator is responsible for monitoring its
temperature and asserting the VR_FAN_N, VR_THERMALERT_N, VR_THERMTRIP_N signals sequentially to inform the processor
and platform of a thermal excursion. Of the three signals, only VR_THERMALTERT_N is monitored by the processor. Please see
the Ararat Voltage Regulator Module Design Guide for further details. The processor is capable of drawing ICC_CORE_TDC
indefinitely. Refer to Figure 2-9
parameter is based on design characterization and is not tested.
2. During system power on, the pulse inrush (ICC_CORE_STEP) can be as high as 130A peak-to-peak.
3. ICC_UNCORE_TDC is the sustained (DC equivalent) current that the processor uncore is capable of drawing indefinitely and
should be used for the Ararat voltage regulator temperature assessment. The Ararat voltage regulator is responsible for
monitoring its temperature and asserting the VR_FAN_N, VR_THERMALERT_N, VR_THERMTRIP_N signals sequentially to inform
the processor and platform of a thermal excursion. Of the three signals, only VR_THERMALTERT_N is monitored by the processor.
Please see the Ararat Voltage Regulator Module Design Guide for further details. The processor is capable of drawing
ICC_UNCORE_TDC indefinitely. This parameter is based on design characterization and is not tested.
4. During system power on, the pulse inrush (ICC_UNCORE_STEP) can be as high as 40A peak-to-peak.
5. The ICC_IO current specification applies to the total current from VCCIO pins.
