This design uses TI's high-performance ARM® Cortex®-M4F based TM4C129x microcontrollers (MCUs) with integrated USB 2.0 controller to interface with an external High Speed USB PHY. The design includes software that allows data exchange between USB high speed and Ethernet. The design also features transceivers for CAN and UART serial interfaces to connect a host to legacy RS232 machines or to interface with CAN bus. Provision for digital communication interfaces like UART: I2C and SSI to bridge external devices and aggregate data from slow interfaces to a high speed USB link has been provided in this reference design.
