Notes:
1. This V_CCO range spans the lowest and highest operating voltages for all supported I/O standards. Table 11 lists the recommended V_CCO
range specific to each of the single-ended I/O standards, and Table 13 lists that specific to the differential standards.
2. Define V_CCAUX selection using CONFIG VCCAUX constraint.
3. See XAPP459, “Eliminating I/O Coupling Effects when Interfacing Large-Swing Single-Ended Signals to User I/O Pins.”
4. For single-ended signals that are placed on a differential-capable I/O, V_IN of –0.2V to –0.5V is supported but can cause increased leakage
between the two pins. See Parasitic Leakage in UG331, Spartan-3 Generation FPGA User Guide.
5. Measured between 10% and 90% V_CCO. Follow Signal Integrity recommendations.
