(1) NA in this table stands for Not Applicable.
(2) For more information on recommended operating conditions, see Section 5.4, Recommended Operating Conditions.
(3) The pullup or pulldown block strength is equal to: minimum = 50 μA, typical = 100 μA, maximum = 250 μA.
(4) The output impedance settings of this IO cell are programmable; by default, the value is DS[1:0] = 10, this means 40 Ω. For more information on DS[1:0] register configuration, see the
Device TRM.
(5) IO drive strength for usb1_dp, usb1_dm, usb2_dp and usb2_dm: minimum 18.3 mA, maximum 89 mA (for a power supply vdda33v_usb1 and vdda33v_usb2 = 3.46 V).
(6) Minimum PU = 900 Ω, maximum PU = 3.090 kΩ and minimum PD = 14.25 kΩ, maximum PD = 24.8 kΩ.
For more information, see chapter 7 of the USB2.0 specification, in particular section Signaling / Device Speed Identification.
(7) This function will not be supported on some pin-compatible roadmap devices. Pin compatibility can be maintained in the future by not using these GPIO signals.
(8) In PUx / PDy, x and y = 60 to 200 μA.
The output impedance settings (or drive strengths) of this IO are programmable (34 Ω, 40 Ω, 48 Ω, 60 Ω, 80 Ω) depending on the values of the I[2:0] registers.
