Overview

The FT232RNL-TUBE is a USB 2.0 to UART bridge IC designed for converting USB data to a serial UART interface. It simplifies the integration of USB connectivity into embedded systems that traditionally use a serial port. This single-chip solution eliminates the need for an external crystal and includes an integrated EEPROM for configuration.

Why Choose This Part

This device offers a high level of integration, featuring an internal clock generator, power-on-reset circuit, and USB termination resistors, which reduces external component count. The integrated 128-byte EEPROM allows for device configuration and customisation. Its full-speed USB 2.0 compatibility ensures reliable data transfer up to 300 baud.

Applications

USB to RS232/RS422/RS485 Converters
Enables easy creation of USB-to-serial adapters for legacy devices and industrial control systems requiring different serial standards.
Microcontroller USB Connectivity
Provides a straightforward method for microcontrollers without native USB capabilities to communicate with a host PC via USB for programming, debugging, or data logging.
USB Instrumentation
Ideal for developing USB-based measurement equipment, data acquisition systems, and other laboratory instruments.
Embedded System Debugging
Offers a reliable USB serial port for console output, command input, and general debugging in embedded development.
Industrial Control Systems
Facilitates USB communication for industrial automation devices, allowing for monitoring and control from a host computer.
