(1)
Typical values are for TA = 25°C, VCCINT = 1.2 V, and VCCIO = 1.5 V, 1.8 V, 2.5 V, and 3.3 V.
(2)
This value is specified for normal device operation. The value may vary during power-up. This applies for all
VCCIO settings (3.3, 2.5, 1.8, and 1.5 V).
(3)
Maximum values depend on the actual TJ and design utilization. See the Excel-based PowerPlay Early Power
Estimator (available at www.altera.com) or the Quartus II PowerPlay Power Analyzer feature for maximum
(4)
Pin pull-up resistance values are lower if an external source drives the pin higher than VCCIO.
