128 / 204 page  Electrical characteristics STM32F405xx, STM32F407xx 128/203 DS8626 Rev 9 USB OTG FS characteristics This interface is present in both the USB OTG HS and USB OTG FS controllers. Table 57. USB OTG FS startup time Symbol Parameter Max Unit tSTARTUP(1) 1. Guaranteed by design. USB OTG FS transceiver startup time 1 µs Table 58. USB OTG FS DC electrical characteristics Symbol Parameter Conditions Min.(1) 1. All the voltages are measured from the local ground potential. Typ. Max.(1) Unit Input levels VDD USB OTG FS operating voltage -3.0(2) 2. The STM32F405xx and STM32F407xx USB OTG FS functionality is ensured down to 2.7 V but not the full USB OTG FS electrical characteristics which are degraded in the 2.7-to-3.0 V VDD voltage range. -3.6 V VDI(3) 3. Guaranteed by design. Differential input sensitivity I(USB_FS_DP/DM, USB_HS_DP/DM) 0.2 - - V VCM(3) Differential common mode range Includes VDI range 0.8 - 2.5 VSE(3) Single ended receiver threshold - 1.3 - 2.0 Output levels VOL Static output level low RL of 1.5 kΩ to 3.6 V(4) 4.
