![]() ![]() The CP2102/9 UART interface implements all RS-232 signals, including control and handshaking signals, so existing system firmware does not need to be modified. Royalty-free Virtual COM Port (VCP) device drivers provided by Silicon Laboratories allow a CP2102/9-based product to appear as a COM port to PC applications. The programmable ROM is programmed on-board via the USB, allowing the programming step to be easily integrated into the product manufacturing and testing process. The on-chip programmable ROM 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. ![]() No other external USB components are required. ![]() The CP2102/9 includes a USB 2.0 fullspeed function controller, USB transceiver, oscillator, EEPROM or EPROM, and asynchronous serial data bus (UART) with full modem control signals in a compact 5 x 5 mm QFN-28 package. The CP2102/9 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. Crystal-less operation, in-system programming memory and small body size packages reduce cost, simplify design and shorten development time. USB Specification 2.Description: The high-performance, low cost CP21xx USB to UART bridge family offers a complete plug and play interface solution that includes royalty-free driver suites and a comprehensive design ecosystem that enables customers to speed time-to-market. 100% pin and software compatible with CP2101 Product ID, serial number, power descriptor, release Internal 1024-byte programmable ROM for vendor ID, Integrated clock no external crystal required Integrated USB transceiver no external resistors The CP2102/9 includes a USB 2.0 full speed function controller, USB transceiver, oscillator, EEPROM or EPROM, and asynchronous serial data bus (UART) with full modem control signals in a compact 5 x 5 mm QFN-28 package. The CP2102/9 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. ![]()
