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 particular segment. The output pin current can be calculated from Table 8 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 8.

1 These values are estimated from simulation and are not tested. Currents apply to output pins only.
