HC1S25 Datasheet, PDF (27/110 Pages) Altera Corporation – HardCopy Stratix Device Family

Operating Conditions
Tables 4–4 through 4–31 list the DC operating specifications for the
supported I/O standards. These tables list minimal specifications only;
HardCopy Stratix devices may exceed these specifications. Table 4–32
provides information on capacitance for 1.5-V HardCopy Stratix
devices.
