Notes:
1.
This VCCO range spans the lowest and highest operating voltages for all supported I/O standards. Table 9 lists the recommended VCCO
range specific to each of the single-ended I/O standards, and Table 11 lists that specific to the differential standards.
2.
Only during DCM operation is it recommended that the rate of change of VCCAUX not exceed 10 mV/ms.
3.
Each of the User I/O and Dual-Purpose pins is associated with one of the four banks’ VCCO rails. Meeting the VIN limit ensures that the
internal diode junctions that exist between these pins and their associated VCCO and GND rails do not turn on. See Absolute Maximum
Ratings in DS312).
4.
All Dedicated pins (PROG_B, DONE, TCK, TDI, TDO, and TMS) draw power from the VCCAUX rail (2.5V). Meeting the VIN max limit ensures
that the internal diode junctions that exist between each of these pins and the VCCAUX and GND rails do not turn on.
5.
Input voltages outside the recommended range is permissible provided that the IIK input clamp diode rating is met and no more than 100 pins
exceed the range simultaneously. See Absolute Maximum Ratings in DS312).
6.
See XAPP459, "Eliminating I/O Coupling Effects when Interfacing Large-Swing Single-Ended Signals to User I/O Pins."
7.
Measured between 10% and 90% VCCO. Follow Signal Integrity recommendations.
