7.7. USB to UART Controller
The TB-KU-xxx-ACDC8K features a Silicon Labs CP2103 USB to UART interface to communicate with a
PC. This module creates a virtual COM port on the computer to allow the user to connect through
standard USB. The USB interface on this card is Micro USB Type AB which mates with either Micro-A or
Micro-B cables.

The UART signals are connected to the FPGA’s single-ended pins on Bank 24. Provided below is a table
indicating where the signals connect. Both the UART transmit and receive data signals are connected as
well as flow control signals.
Using the PC’s virtual COM port drivers, there are different supported baud
rates that are compatible with this controller and can be set during the COM port configuration.
