(2) For more information on recommended operating conditions, see Table 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) 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. (8) The VOUT3 interface when multiplexed onto balls mapped to the VDDSHV6 supply rail is restricted to operating in 1.8V mode only (VDDSHV6 must be supplied with 1.8V). 3.3V mode is not supported. This must be considered in the pin mux programming and VDDSHVx supply connections. (9) The internal pull resistors for balls K7, M7, J5, K6, J4, J6, H4, H5 are permanently disabled when sysboot15 is set to 1 as described in the section Sysboot Configuration of the Device TRM. If internal pull-up/down resistors are desired on these balls then sysboot15 should be set to 0. If gpmc boot mode is used with SYSBOOT15=1 (not recommended) then external pull-downs should be implemented to keep the address bus at logic-0 value during boot since the gpmc ms-address bits are high-z during boot. |
