CP2103-GM информация о продукте

The CP2103 is a highly-integrated USB-to-UART Bridge Controller providing a simple solution for updating RS-232/RS-485 designs to USB using a minimum of components and PCB space. The CP2103 includes a USB 2.0 full-speed function controller, USB transceiver, oscillator, EEPROM, and asynchronous serial data bus (UART) with full modem control signals in a compact 5x5 mm QFN-28 package (sometimes called “MLF” or “MLP”). No other external USB components are required. The on-chip EEPROM 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. 

The EEPROM is programmed on-board via the USB, allowing 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 CP2103-based product to appear as a COM port to PC applications. The CP2103 UART interface implements all RS-232/RS-485 signals, including control and handshaking signals; so, existing system firmware does not need to be modified. The device also features up to four GPIO signals that can be user-defined for status and control information. Support for I/O interface voltages down to 1.8 V is provided via a VIO pin. 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 CP2103. Direct access driver support is available through the Silicon Laboratories USBXpress driver set. An evaluation kit for the CP2103 (Part Number: CP2103EK) is available. It includes a CP2103-based USB-toUART/RS-232 evaluation board, a complete set of VCP device drivers, USB and RS-232 cables, and complete documentation. Contact a Silicon Labs sales representatives or visit www.silabs.com to order the CP2103 Evaluation Kit.
