I/O pad VRC33 current specifications

The power consumption of the VRC33 supply is dependent on the usage of the pins on all

I/O segments. The power consumption is the sum of all output pin VRC33 currents for all I/O

segments. The output pin VRC33 current can be calculated from Table 25 based on the

voltage, frequency, and load on all medium, slow, and multv_hv pins. The output pin VRC33

current can be calculated from Table 26 based on the voltage, frequency, and load on all

fast pins. Use linear scaling to calculate pin currents for voltage, frequency, and load

parameters that fall outside the values given in Table 25 and Table 26.
