(2) These I/O specifications apply to regular 3.3 V 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) See Section 5.9.2.4. Also, resistors should be E-96 spec line (3 digits with 1% accuracy). (4) Connect USB_R1 to VSS_USB_REF via 10K ohm, 1% resistor placed as close to the device as possible.
