Notes:
1. This V
range spans the lowest and highest operating voltages for all supported I/O standards. Table 80 lists the recommended V

range specific to each of the single-ended I/O standards, and Table 82 lists that specific to the differential standards.
2. Each of the User I/O and Dual-Purpose pins is associated with one of the four banks’ V rails. Meeting the V limit ensures that the

3. All Dedicated pins (PROG_B, DONE, TCK, TDI, TDO, and TMS) draw power from the V
rail (2.5V). Meeting the V max limit ensures
