SiLCP2102N-A02-GQFN20

Overview

The CP2102N-A02-GQFN20 is a highly integrated USB-to-UART bridge designed to provide a simple solution for updating RS-232 designs to USB. This fixed-function device eliminates the need for firmware development by utilizing a pre-programmed USBXpress controller that handles all USB protocol requirements. It features a compact 3x3 mm QFN20 package and supports data rates up to 3 Mbaud with an integrated clock and voltage regulator.

Why Choose This Part

This bridge reduces BoM cost and PCB footprint by integrating the USB transceiver, clock, and voltage regulator into a single package with no external crystal required. It simplifies development through a GUI-based configuration utility and royalty-free drivers, while supporting high-speed transfers up to 3 Mbaud and hardware handshaking.

Applications

Getting Started

To begin evaluation, use the CP2102N-EK development kit which provides header access to all GPIOs and UART signals. Configuration of internal parameters like Vid/Pid and power descriptors is performed via the Simplicity Studio Xpress Configurator tool. Silicon Labs provides royalty-free Virtual COM Port (VCP) drivers for Windows, macOS, and Linux to facilitate immediate host communication.
