Overview

The FT232RNL-REEL is a highly integrated USB-to-UART bridge IC that simplifies the implementation of USB 2.0 full-speed connectivity in embedded systems. It features an onboard oscillator, 1024-bit EEPROM, and termination resistors, significantly reducing the external Bill of Materials. The device supports data rates from 300 baud to 3 Mbaud and includes configurable CBUS pins for custom I/O functions.

Why Choose This Part

This IC eliminates the need for an external crystal and provides integrated level shifting to support I/O voltages down to 1.8V. The availability of royalty-free drivers for Windows, Mac, and Linux ensures rapid software deployment and long-term OS compatibility.

Applications

USB-to-RS232/RS485 Converters
Providing a reliable bridge between legacy serial protocols and modern USB-enabled host systems.
Microcontroller Debugging
Integrating onto development boards to provide a robust serial console for firmware debugging and programming.
Industrial Data Logging
Interfacing sensors and industrial equipment to PCs for high-reliability data acquisition over USB.
