Table 7-7. DC Electrical Characteristics (Power and Current)
7.5 Power Sequencing
In order to prevent latch-up, it is recommended that the 44x0/84x0 power supplies be
brought up starting with the highest voltage first and ending with the lowest voltage. It is
also permitted to bring up the supplies simultaneously, making sure that the lower-voltage
supplies do not exceed the higher-voltage supplies during the ramp. The intent is to make

1. The DC information is preliminary and subject to change.
2. The current consumption for core, PLL, and I/O subsections represent peak instantaneous current
requirements and should be used for power planning. The sum of these current requirements will
exceed the maximum power numbers (PIO and PCORE), which represent average worst-case
thermal parameters.
