4.7.1 I/O Pad Current Specifications
The power consumption of an I/O segment is dependent 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 15 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 15.
The AC timing of these pads are described in the Section 4.11.2, “Pad AC Specifications.”

Power requirements for the V

supply depend on the frequency of operation and load of all I/O pins, and the voltages on
the I/O segments.

This value is a target that is subject to change.
16
This value allows a 5 V reference to supply ADC + REF.
17
Power requirements for each I/O segment depend on the frequency of operation and load of the I/O pins on a particular I/O
segment, and the voltage of the I/O segment. See Section 4.7.1, “I/O Pad Current Specifications,” for information on I/O pad
power. Also refer to Table 15 for values to calculate power dissipation for specific operation. The total power consumption of
an I/O segment is the sum of the individual power consumptions for each pin on the segment.
