CP2102N USBXpress™ USB-to-UART Bridge Controller

Silicon Labs CP2102N USBXpress™ USB-to-UART Bridge Controller updates RS-232 designs to USB using minimum components and PCB space. The CP2102N includes a USB 2.0 full-speed function controller, USB transceiver, oscillator, and Universal Asynchronous Receiver/Transmitter (UART). The Controller is housed in packages as small as 3mm x 3mm. No other external USB components are required.
