TTL-232RG-VSW3V3-WE

FTDI, Future Technology Devices International Ltd
USB to TTL Serial 3.3V Cable 5.90' (1.80m) Unshielded
Active

Overview

The TTL-232RG-VSW3V3-WE is a USB to serial UART converter cable incorporating the FT232RQ interface IC. It provides a simple method for connecting asynchronous serial devices to USB while handling all USB signaling and protocols. The cable is 1.8 meters long and features 6 wire leads for easy integration into custom projects or existing hardware.

Why Choose This Part

This cable integrates the entire conversion circuit into the USB connector, saving PCB space in the target application. It provides a fixed 3.3V output on the VCC wire with up to 50mA current capability to power small downstream circuits. The wire-ended design offers maximum flexibility for engineers to add their own proprietary or application-specific connectors.

Applications

Embedded System Debugging
Direct connection to microcontroller UART pins for real-time firmware debugging and log monitoring.
Legacy Peripheral Support
Updating older RS-232 based equipment to interface with modern USB-only host computers.
Custom Industrial Interfaces
Permanent installation in industrial enclosures where a standard header is not present, utilizing the wire-ended leads for direct soldering.
3.3V Logic Level Interfacing
Safely communicating with low-voltage sensors and processors that require 3.3V TTL logic levels.

Getting Started

To use this cable, install the FTDI VCP (Virtual COM Port) drivers to make the device appear as a standard serial port in your operating system. Connect the Black (GND), Yellow (RXD), and Orange (TXD) wires to your target system, ensuring the logic levels match the 3.3V rating. Terminal software such as PuTTY or Tera Term can be used to initiate serial communication at various standard baud rates.
