Each UART supports full modem control signals (RTS\/CTS\/DTR\/DSR\/DCD\/RI) and baud rates from 300 bps to 2 Mbps. The on-chip EEPROM stores customizable USB descriptors (VID\/PID\/serial number). Integrated USB transceiver, oscillator, and voltage regulator minimize external components. 16 GPIO pins provide additional I\/O flexibility.","working_principle":"The CP2108 enumerates as a composite USB device with four virtual COM ports. USB data is received by the function controller and routed to the appropriate UART channel via internal FIFOs. Each UART independently converts between USB data packets and asynchronous serial format. The on-chip EEPROM is programmed via USB to store vendor-specific configuration. VCP drivers translate USB data to standard COM port API calls on the host.","pin_description":"
