Overview

The CP2102N-A02-GQFN28R is a highly integrated USB-to-UART bridge controller designed to replace RS-232 designs with minimal components. Part of the USBXpress family, it eliminates the need for complex firmware development by providing a direct plug-and-play solution for serial communication over USB 2.0.

Why Choose This Part

This controller integrates an internal voltage regulator and a precision oscillator, removing the requirement for external crystals or resistors. It supports data rates up to 3 Mbps and includes 960 bytes of user-programmable ROM for custom VID/PID and serial number configuration.

Applications

Legacy RS-232 to USB Upgrades
Replacing bulky DB9 connectors and level shifters with a modern USB interface in existing industrial equipment.
Embedded System Debug Ports
Providing a reliable UART terminal interface for firmware debugging and system monitoring via a standard USB cable.
USB Dongles and Adapters
Creating compact communication bridges for connecting sensors or microcontrollers to a PC or single-board computer.
Industrial Control Panels
Enabling high-speed data logging and configuration updates in environments requiring robust serial communication.

Getting Started

Designers can use the Simplicity Studio IDE to access the Xpress Configurator for tailoring device parameters without writing code. For hardware evaluation, the CP2102N-EK evaluation kit provides a ready-to-use platform with access to all GPIOs and handshaking signals.
