1. Describe

CP2102-GMR is a highly integrated USB-to-UART bridge controller, which provides a simple solution for updating the RS232 design to USB using the least components and PCB space. CP2102/9 includes a USB 2.0 full-speed functional controller, USB transceiver, oscillator, EEPROM or EPROM, and asynchronous serial data bus (UART) with complete modem control signals in a compact 5 x 5 mm QFN-28 package . No other external USB components are required. On-chip programmable ROM can be used to customize USB manufacturer ID, product ID, product description Strings, power descriptors, device version numbers, and device serial numbers required by OEM applications. Programmable ROM can be programmed on-board via USB to easily complete the programming steps Integrate into the product manufacturing and testing process. The royalty-free virtual COM port (VCP) device driver provided by Silicon Laboratories allows The product is shown as the COM port of the PC application. CP2102/9 UART interface realizes full RS-232 Signals, including control signals and handshake signals, so there is no need to modify the existing system firmware. exist For many existing RS-232 designs, all that is required to update the design from RS-232 to USB is to replace the RS232 level converter with CP2102/9. Silicon Laboratories provides direct access driver support USBXpress driver set. Provide CP2102 evaluation kit (part number: CP2102EK). The kit includes a CP2102-based USB-toUART/RS-232 evaluation board, a complete set of VCP device drivers, USB and RS-232 cables, and a complete Documentation.
