6. Asynchronous Serial Data Bus (UART) Interface
The CP2103 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. The data format and baud rate
programmed into the UART is set during COM port configuration on the PC. The data formats and baud rates
available are listed in Table 7.

8. Internal EEPROM
The CP2103 includes an internal EEPROM that may be used to customize the USB Vendor ID, Product ID,
Product Description String, Power Descriptor, Device Release Number, and Device Serial Number as desired for
OEM applications. Customization of the USB configuration data is optional. If the EEPROM is not programmed
with OEM data, the default configuration data shown in Table 8 is used. However, a unique serial number is
required for OEM applications in which it is possible for multiple CP2103-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 CP2103 on-board during the manufacturing and testing process. A stand-alone utility
for programming the internal EEPROM is available from Silicon Laboratories. A library of routines provided in the
form of a Windows DLL is also available. This library can be used to integrate the EEPROM programming step
into custom software used by the OEM to streamline testing and serial number management during manufacturing.
The EEPROM has a typical endurance of 100,000 write cycles with a data retention of 100 years.
USB descriptors can be locked to prevent future modification.
