Overview

The CP2102N-A02-GQFN28 is a USB-to-UART bridge IC from Silicon Labs in a 28-pin QFN package. It provides a simple serial link between a USB host and a UART peripheral, supports USB 2.0, and handles baud rates up to 3 Mbaud. Its small QFN footprint is aimed at space-constrained embedded designs where a drop-in serial converter is needed.

Why Choose This Part

Provides an integrated USB physical interface and UART bridge in a single small package, reducing component count and board area. Supports high UART speeds (up to 3 Mbaud) for low-latency/ high-throughput serial applications. Silicon Labs supplies drivers and host utilities, simplifying host-side integration and cross-platform support.

Applications

Firmware flashing and device console
Provide a USB serial console and bootloader/programming interface for MCUs and SoCs that lack native USB.
USB connectivity for embedded modules
Add USB-host connectivity to sensor modules, gateways, or custom PCBs via a UART bridge.
High-speed serial data logging
Stream debug logs or telemetry to a PC at baud rates up to 3 Mbaud for development and testing.
Factory programming and test fixtures
Use as a reliable USB-to-UART link in automated production test stations and programming jigs.
PC-to-equipment serial interface
Replace legacy RS-232/RS-485 adapters in applications where TTL UART levels are acceptable.

Getting Started

Download Silicon Labs Virtual COM Port (VCP) drivers and utilities and use Simplicity Studio or the Silicon Labs website for device configuration and firmware tools. For development, use a CP2102N evaluation board or a QFN breakout adapter to ease hardware connections if you do not have a module. Confirm required UART voltage levels and route required USB D+/D- and power pins carefully on your PCB layout.
