3.8.1 I/O Pad Current Specifications
The power consumption of an I/O segment depends on the usage of the pins on a particular segment. The
power consumption is the sum of all output pin currents for a segment. The output pin current can be
calculated from Table 10 based on the voltage, frequency, and load on the pin. Use linear scaling to
calculate pin currents for voltage, frequency, and load parameters that fall outside the values given in
Table 10.
