CP2102N Data Sheet
The CP2102N devices, part of the USBXpress family, are de-
signed 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 cus-
tomization and configuration options can be selected using a simple GUI-based config-
urator. By eliminating the need for complex firmware and driver development, the
CP2102N devices enable quick USB connectivity with minimal development effort.
CP2102N is ideal for a wide range of applications, including the following:
• POS terminals
• USB dongles
• Medical equipment
• Data loggers
• Gaming controllers
