SINGLE-CHIP USB-TO-UART BRIDGE

Silicon Laboratories 

CP2102/9

7. Asynchronous Serial Data Bus (UART) Interface

The CP2102/9 UART interface consists of the TX (transmit) and RX (receive) data signals as well as the RTS,

CTS, DSR, DTR, DCD, and RI control signals. The UART supports RTS/CTS, DSR/DTR, and X-On/X-Off

handshaking.

The UART is programmable to support a variety of data formats and baud rates. If the Virtual COM Port drivers are

used, the data format and baud rate are set during COM port configuration on the PC. If the USBXpress drivers are

used, the CP2102/9 is configured through the USBXpress API. The data formats and baud rates available are

listed in Table 12.
