FT234XD-R

Controllers Overview

The FT234XD-R is a USB to UART Bridge Controller manufactured by FTDI. It supports USB 2.0 Full Speed at 12 Mbps and provides a basic UART interface with programmable baud rates ranging from 300 bps to 3 Mbps. The device operates within a supply voltage range of 1.8 V to 5.5 V, with typical operation at 3.3 V or 5 V. It features an integrated +3.3 V LDO regulator and supports hardware flow control via RTS# and CTS# pins. The component is housed in a 12-pin DFN EP package with exposed pad for surface mount mounting. It functions within an industrial temperature range of -40°C to 85°C and has a maximum supply current of 8.3 mA.

Controllers Feature Summary

• Integrates USB 2.0 full-speed controller with basic UART bridge functionality
• Includes built-in +3.3V low-dropout regulator for I/O power
• Supports configurable hardware flow control signals
• Provides flexible I/O voltage compatibility

Controllers Applications

• USB to serial communication interfaces for embedded systems
• Development and debugging tools for microcontroller platforms
• Industrial data acquisition modules requiring serial connectivity

Controllers Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's latest datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure proper ESD handling procedures are followed during storage and assembly due to the small form factor.

Controllers Selection Notes

Select this component when a compact USB-to-serial solution is required for space-constrained designs. Consider the 12-pin DFN package dimensions and thermal dissipation characteristics relative to the PCB layout. Verify that the required I/O voltage levels align with the target system's logic standards before finalizing the bill of materials.

Controllers Part Context

This part belongs to the FT234x family of USB-UART bridge controllers designed for cost-sensitive and space-efficient applications. It serves as a direct replacement for legacy USB-to-serial adapters while offering improved integration through internal regulation. The series is widely used in consumer electronics and industrial automation for reliable serial data transmission over USB connections.

Controllers Replacement Considerations

The FT230XQ-R is a related component within the same product family, offering similar USB-to-UART functionality but in a 16-pin QFN EP package. Designers should verify pinout compatibility and package footprint differences when considering substitution between these variants.
