(1)
For test conditions shown as MIN, MAX, or NOM, use the appropriate value specified in the recommended operating conditions table.
(2)
These I/O specifications apply to regular 3.3 V and 1.8V I/Os and do not apply to DDR2/mDDR, USB I/Os. DDR2/mDDR I/Os are 1.8 V
I/Os and adhere to JESD79-2A standard, USB I/Os adhere to USB2.0 spec.
(3)
This specification applies only to pins with an internal pullup (PU) or pulldown (PD). See or
Section 2.8 for pin descriptions.
(4)
To pull up a signal to the opposite supply rail, a 1 k
resistor is recommended.
(5)
IOZ applies to output only pins, indicating off-state (Hi-Z) output leakage current.
