(1) These IO specifications apply to the dual-voltage IOs only and do not apply to DDR2/mDDR or SATA interfaces. DDR2/mDDR IOs are
1.8V IOs and adhere to the JESD79-2A standard. USB0 I/Os adhere to the USB2.0 standard. USB1 I/Os adhere to the USB1.1
standard. SATA I/Os adhere to the SATA-I and SATA-II standards.
(2) I_I applies to input-only pins and bi-directional pins. For input-only pins, I_I indicates the input leakage current. For bi-directional pins, I_I
indicates the input leakage current and off-state (Hi-Z) output leakage current.
(3) Applies only to pins with an internal pullup (IPU) or pulldown (IPD) resistor. The pull-up and pull-down strengths shown represent the
minimum and maximum strength across process variation.
