Electrical Characteristics
31.20
Universal Serial Bus (USB) Controller
The Tiva™ C Series USB controller electrical specifications are compliant with the Universal Serial
Bus Specification Rev. 2.0 (full-speed and low-speed support) and the On-The-Go Supplement to
the USB 2.0 Specification Rev. 1.0. Some components of the USB system are integrated within the
TM4C129LNCZAD microcontroller and specific to the Tiva™ C Series microcontroller design.
Note: GPIO pin, PB1, which can be configured as the USB0VBUS signal, is the only pin which is
5-V tolerant on the device.
