Overview

FT232RNQ-REEL is FTDI's FT232R USB-to-UART bridge IC in a QFN-32 package. It lets a microcontroller or other serial device appear as a USB serial port on a PC, with the USB full-speed interface, clock generation, and EEPROM support built into the chip. This reduces external component count for USB-to-serial designs.

Why Choose This Part

The FT232RNQ-REEL combines the USB interface, oscillator, and EEPROM support in one device, which can simplify the surrounding BOM and PCB layout. It is a practical choice when you want a well-known USB-to-UART bridge with minimal external parts and straightforward integration into embedded designs. The QFN package also suits compact hardware where board area matters.

Applications

USB-to-UART adapters
Create compact bridge boards that convert USB to TTL serial for firmware upload, debug consoles, and terminal access.
Embedded board serial ports
Add a PC-facing USB port to microcontroller, FPGA, or ASIC designs that already use UART for control or logging.
Industrial service interfaces
Provide maintenance and configuration access on equipment that exposes a UART for setup, diagnostics, or production test.
Prototype and development hardware
Use on custom breakouts and dev boards where a simple, reliable USB serial interface is needed.
Legacy device PC connectivity
Bridge older serial peripherals into USB-based systems without redesigning the target-side UART interface.

Getting Started

Design it as a standard USB-to-UART bridge and follow FTDI's reference design and driver guidance. On the host side, common operating systems typically recognize FTDI-based USB serial devices through vendor-provided or built-in drivers, and on the target side you connect TX, RX, and GND like any UART link. For first hardware bring-up, verify USB power, connector routing, and UART logic levels before relying on automatic enumeration.
