Overview

The CP2102N-A02-GQFN24 is a highly integrated USB-to-UART bridge designed to provide a simple solution for updating RS-232 designs to USB. It includes a USB 2.0 full-speed function controller, USB transceiver, oscillator, and UART in a compact 4x4 mm QFN24 package. The device eliminates the need for external crystals or resistors, significantly reducing BOM count and PCB footprint.

Why Choose This Part

This bridge offers baud rates up to 3 Mbaud and features 5V tolerant I/O, making it compatible with a wide range of logic levels. The integrated voltage regulator and internal clock source simplify hardware design by removing the need for external timing components. Additionally, it supports USB Battery Charger Detection (BCS 1.2) to help optimize power delivery in portable applications.

Applications

Legacy RS-232 to USB Upgrades
Easily replace bulky serial connectors with a modern USB interface without modifying existing system firmware.
USB Dongles and Flash Drives
Small form factor and low current consumption (9.5mA) make it ideal for portable bus-powered peripherals.
Medical Device Interfaces
Utilized in diagnostic equipment for reliable data transfer to host PCs via standard Virtual COM Port drivers.
Industrial Controller Debugging
Provides a robust serial bridge for PLC or motor controller programming interfaces in harsh environments.

Getting Started

Implementation requires no firmware development; the device is configured using the Silicon Labs Simplicity Studio Xpress Configurator GUI. Engineers can jump-start development using the CP2102N-EK evaluation kit. Virtual COM Port (VCP) drivers are available for Windows, macOS, and Linux to treat the USB interface as a standard serial port.
