CP2102 chip is a single-chip USB to UART bridge IC. It requires minimal external components. CP2102 can be used to migrate legacy serial port based devices to USB. CP2102 its a highly integrated, built-in USB2.0 full-speed function controller, USB transceiver, crystal oscillator, EEPROM, and asynchronous serial data bus (UART), to support a full-featured modem signal without any external USB devices. Similar to other works CP2102 USB-UART switching circuit by the driver into the PC’s USB port virtual COM port expansion to achieve the purpose.
