Intel Pentium 4 Processor-M power supply requirements, please refer to the
RS-Intel Mobile
Voltage Positioning (IMVP)-III Mobile Processor Core Voltage Regulator Specification Design
Guide.
Power source characteristics must be stable whenever the supply to the voltage regulator is stable.
Refer to the
Figure 16
for timing details of the power up sequence. Also refer to
Mobile Intel
Pentium
4 Processor-M and Intel
845MP/845MZ Chipset Platform Design Guide
for
implementation details.
Mobile Intel Pentium 4 Processor-M’s Voltage Identification circuit requires an independent 1.2-V
supply. This voltage must be routed to the processor VCCVID pin.
Figure 1
shows the voltage and
current requirements of the VCCVID pin.
