FT230XQ-T

Controllers Overview

The FT230XQ-T is a USB to UART Bridge Controller from FTDI, designed for compact PCB integration. It operates on a single +5V supply with internal LDO regulators for 3.3V and 1.8V outputs. The device supports data rates from 300 baud to 3 MBd across RS232, RS422, RS485, and TTL levels. It features 512-byte receive and transmit buffers, integrated MTP memory for configuration, and built-in clock generation without external crystals. The component is housed in a 16-pin QFN EP package and complies with USB 2.0 Full Speed standards.

Controllers Feature Summary

• Integrated MTP memory stores device descriptors and CBUS I/O configurations without external components.
• Built-in clock generation eliminates the need for external crystal oscillators.
• Supports configurable CBUS I/O pins for custom functionality and LED driving.
• Includes USB battery charger detection for optimized power sourcing.

Controllers Applications

• Converting USB host ports to asynchronous serial interfaces for legacy devices.
• Connecting microcontrollers or FPGAs via synchronous/asynchronous bit-bang modes.
• Implementing low-power USB peripherals with bus-powered or self-powered configurations.

Controllers Procurement Notes

Verify the suffix 'T' indicates tray packaging when ordering. Confirm the specific voltage variant matches system requirements, as the FT230X series includes options for different supply ranges. Ensure ESD protection measures are adequate during handling of the QFN EP package. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Controllers Selection Notes

Select the FT230XQ-T over tape-and-reel variants when manual placement or small-batch prototyping is required. Consider the FT230XS if SSOP packaging is preferred for through-hole assembly. Evaluate the FT230H or FT2232H if higher speeds or multiple channels are necessary. Verify that the 16-pin QFN footprint aligns with the target PCB layout constraints.

Controllers Part Context

The FT230XQ-T belongs to the FT-X series, which focuses on cost-effective USB-to-serial solutions. It shares core architecture with the FT230XQ-R but differs in packaging format. This series extends FTDI's portfolio by offering optimized pin counts and reduced PCB real estate compared to older FT232R models.

Controllers Replacement Considerations

The FT230XQ-R is the direct functional equivalent in tape-and-reel packaging. The FT230XS offers identical electrical performance in an SSOP package. No direct pin-compatible alternatives exist outside the FT-X family without schematic modifications.
