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 input and output pin VRC33 currents for all I/O segments. The output pin VRC33 current can be calculated from

Table 22 based on the voltage, frequency, and load on all fast pins. The input pin VRC33 current can be calculated from Table 22

based on the voltage, frequency, and load on all medium pins. Use linear scaling to calculate pin currents for voltage, frequency,

and load parameters that fall outside the values given in Table 22.
