FT230XQ R USB to UART Converter Specifications Applications and Suppliers

ElecSuppliers Part Number GuideAug 15, 2026

FT230XQ R is a USB to UART interface IC from FTDI designed to provide USB connectivity for systems that use a UART serial interface.

It is particularly useful when an embedded device needs to communicate with a computer through USB without requiring the main microcontroller to handle the USB protocol directly.

The complete part number is important when sourcing the device because USB interface ICs can differ in package, interface configuration and supported functions even when they serve a similar purpose.

What Does FT230XQ R Do

The main function of FT230XQ R is to convert data between a USB interface and a UART serial interface.

On one side, the device communicates with a USB host such as a computer. On the other side, it provides UART signals that can connect to a microcontroller, embedded processor or other serial device.

This makes it useful for adding USB connectivity to products that already have a UART based communication architecture.

FT230XQ R in Embedded Systems

Many microcontrollers provide UART interfaces but do not necessarily include the USB functionality required for direct connection to a computer.

FT230XQ R can bridge this gap.

A typical design can connect the UART pins of the FT230XQ R to a microcontroller while the USB side is connected to a USB connector. The host computer can then communicate with the embedded system through the USB interface.

This approach can simplify the hardware design when USB is mainly required for configuration, debugging, firmware communication or data transfer.

FT230XQ R Applications

FT230XQ R can be used in a range of embedded and industrial electronic products.

Possible applications include USB serial adapters, development boards, embedded controllers, instrumentation equipment, industrial interfaces and products that require a USB connection to an existing UART based system.

It can also be useful during product development when engineers need a convenient way to communicate with a microcontroller through a computer.

FT230XQ R Interface Design

When designing with FT230XQ R, engineers need to consider both sides of the interface.

The USB connection requires appropriate USB routing and supporting components, while the UART side needs to match the voltage levels and communication requirements of the connected processor.

The power supply arrangement, USB connector, signal routing and PCB layout should follow the manufacturer's design recommendations.

FT230XQ R Package

The package is an important consideration when placing FT230XQ R on a PCB.

Engineers should verify the package dimensions, pin assignment and recommended PCB footprint before starting the board layout.

For compact embedded products, the package size can also influence the placement of the USB connector and the routing between the USB interface IC and the main controller.

FT230XQ R Supplier Information

When searching for FT230XQ R suppliers, buyers should use the complete manufacturer part number to avoid confusion with other FTDI USB interface products.

Supplier quotations should be checked for the exact MPN, package, product status and required quantity.

For an existing BOM, replacing FT230XQ R with another USB UART device should not be based solely on the fact that both components provide USB to serial conversion. Pin compatibility, software support, electrical characteristics and PCB requirements should also be evaluated.
