... Royalty-free Virtual COM Port (VCP) device drivers provided by Silicon Laboratories allow a CP2102-based product to appear as a COM port to PC applications. The CP2102 UART interface implements all RS-232 signals, including control and handshaking signals, so existing system firmware does not need to be modified. In many existing RS-232 designs, all that is required to update the design from RS-232 to USB is to replace the RS-232 level-translator with the CP2102 ...

... USB Function Controller and Transceiver The Universal Serial Bus function controller in the CP2102 is a USB 2.0 compliant full-speed device with integrated transceiver and on-chip matching and pull-up resistors. The USB function controller manages all data transfers between the USB and the UART as well as command requests generated by the USB host controller and commands for controlling the function of the UART ...

... Silicon Laboratories VID also recommended to customize the serial number if the OEM application is one in which it is possible for multiple CP2102-based devices to be connected to the same PC. The internal EEPROM is programmed via the USB. This allows the OEM's USB configuration data and serial number to be written to the CP2102 on-board during the manufacturing and testing process ...
