6300ESB ICH Embedded Platform Design Guide
4.6 Power Delivery Map
Figure 48 depicts power delivery map for an example Intel 855GME chipset/6300ESB platform.
During STR, only the necessary devices are powered. These devices include: main memory, the
6300ESB resume well, PCI wake devices (via 3.3 Vaux), AC’97, and USB. To ensure that enough
power is available during STR, a thorough power budget shall be completed. Power requirements
shall include each device’s power requirements, both in suspend and in full-power. The power
requirements shall be compared with the power budget supplied by the power supply. Due to the
requirements of main memory and the PCI 3.3 Vaux (and possibly other devices in the system), it is
necessary to create dual power rails.
The solutions in this Design Guide are only examples. Many power distribution methods achieve
similar results. When deviating from these examples, it is critical to consider the effect of a change.
