Notes to Table 4–4:

(1)

Typical values are for TA = 25° C, VCCINT = 1.2 V, and VCCIO = 1.5-, 1.8-, 2.5-, 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)

This specification is preliminary and pending further device characterization.

(4)

Pin pull-up resistor values will lower if an external source drives the pin higher than VCCIO.

(5)

Maximum values depend on the actual TJ and design utilization. See the PowerPlay Early Power Estimator or the

Quartus II PowerPlay Power Analyzer feature for maximum values.
