About CP2102

     The CP2102 is a highly-integrated USB-to-UART Bridge controller providing a simple solution for updating RS-232 designs to USB using a minimum of components and PCB space. The CP2102 includes a USB2.0 full speed function controller, USB transceiver, oscillator, EEPROM, and asynchronous serial data bus(UART) with full modem control signals in a compact 5 x 5mm QFN-28 package. No other external USB components are required. The on-chip EEPROM may be used to customized the USB Vendor ID, product ID, product description string, power descriptor, device release number and device serial number as desired for OEM applications. The EEPROM is programmed on-board via the USB, allowering the programming step to be easily integrated into the product manufacturing and testing process.

     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 RS232 to USB to replace the RS232 level-translator with the CP2102. Direct access driver support is available through the Silicom Laboratories USBXpress ddriver set.


About PL2303

The PL-2303 USB-to-Serial Bridge Controller is a low cost and high performance single chip solution. It provides a simple and easy way to use bridge/connectivity between the Universal Serial Bus (USB) and Serial Port interface. With the advantage of USB port, users have the capability to utilize the peripheral with serial port interface in an easy-to-use environment such as plug and play & hot swap function. This single chip is designed for ideal connections to Cellular Phone, Digital Camera, Modems or ISDN terminal adapters with over 1Mbps data transfer rate. The PL-2303 device and software drivers are capable of providing a no-firmware-change feature that enable USB interface to be transparent to serial port peripherals with minimum modifications

  • Full compliance with the USB Specification v1.1(0) and USB CDC v1.1
  • Support the RS232 Serial interface
  • Support automatic handshake mode
  • Over 1Mbps data transfer rate
