Overview

The CP2102N-A02-GQFN24R is a highly integrated USB-to-UART bridge controller designed to provide a simple solution for updating RS-232 designs to USB. It eliminates the need for complex firmware development by providing a turnkey solution with an integrated USB 2.0 full-speed transceiver, voltage regulator, and internal oscillator. The device supports data rates from 300 baud up to 3 Mbaud and includes 960 bytes of user-programmable EEPROM for storing custom USB descriptors.

Why Choose This Part

This controller minimizes PCB footprint by integrating the USB transceiver and clock, requiring no external crystal. Its 5V tolerant I/O and on-chip 3.3V regulator simplify interfacing with various logic levels, while the GUI-based Xpress Configurator tool allows engineers to customize VID/PID and string descriptors without writing any code.

Applications

Legacy RS-232 to USB Upgrades
Replacing bulky DB9 connectors with modern USB interfaces in existing industrial or consumer designs without rewriting system firmware.
USB Dongles and Adapters
Creating compact USB-to-TTL serial adapters for debugging and interfacing with microcontroller UART ports.
Battery-Powered Handheld Devices
Utilizing USB Battery Charger Detection (BCS 1.2) to identify power source capabilities for optimized charging cycles.
Industrial Control Modules
Providing a robust serial communication link for PLC programming ports or sensor hub data logging.
