Notes to Table 5–4:
(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
values. See the section “Power Consumption” on page 5–20 for more information.
(4) Pin pull-up resistance values are lower if an external source drives the pin higher than VCCIO
.
