USB-to-UART Bridge
CP2102N-A02-GQFN24 is a highly integrated USB-to-UART bridge controller from Silicon Labs. It provides a simple and cost-effective way to add USB connectivity to embedded systems by converting USB 2.0 Full-Speed communication into a standard UART interface. The device integrates the USB transceiver, oscillator, voltage regulator, and UART controller, minimizing external components and eliminating the need for USB firmware development. It is commonly used in microcontroller programming interfaces, industrial equipment, POS terminals, data loggers, and USB-to-serial adapters.
