CP2102N USBXpress USB Bridges

The CP2102N devices, part of the USBXpress family, are designed to quickly add USB to your applications by eliminating firmware complexity and reducing development time. These highly-integrated USB-to-UART bridge controllers provide a simple solution for updating RS-232 designs to USB using a minimum of components and PCB space.

CP2102N includes a USB 2.0 full-speed function controller, USB transceiver, oscillator, and Universal Asynchronous Receiver/Transmitter (UART) in packages as small as 3 mm x 3 mm. No other external USB components are required for development. All customization and configuration options can be selected using a simple GUI-based configurator. By eliminating the need for complex firmware and driver development, the CP2102N devices enable quick USB connectivity with minimal development effort.
