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 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.

Table 10. I/O Pad Average DC Current1

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