FT201XQ-T

Controllers Overview

The FT201XQ-T is a USB to I2C interface integrated circuit manufactured by FTDI. It supports Full Speed USB 2.0 communication with a maximum data rate of 3.4 Mbps. The device operates on a single 3.3V power supply and features 512-bit transmit and receive FIFOs. It is housed in a 16-pin QFN package with dimensions of 4x4 mm and a height of 0.9 mm. The component functions as an asynchronous receiver/transmitter for serial communication.

Controllers Feature Summary

• Provides USB 2.0 to I2C bridge functionality
• Includes dedicated battery charger detection capability
• Integrates 512-bit transmit and receive FIFO buffers

Controllers Applications

• Evaluation of FT201XQ interface capabilities
• Development of USB-to-I2C conversion systems
• Integration into devices requiring battery charging port detection

Controllers Procurement Notes

Verify the specific suffix 'T' indicates tray packaging when sourcing. Confirm the active status of the component, as related development boards like UMFT201XA-02 are marked obsolete. Ensure compatibility with 3.3V logic levels during integration planning.

Controllers Selection Notes

Select this part for applications requiring a compact USB-to-I2C solution with built-in FIFO buffering. Compare against the SSOP variant (FT201XS-R) if surface mount footprint constraints differ. Verify that the 3.4 Mbps speed meets system timing requirements.

Controllers Part Context

This component belongs to the FT-X series of USB interface ICs from FTDI. It is designed to replace legacy UART interfaces with modern USB connectivity while maintaining simple I2C protocol support. The QFN package allows for low-profile board designs.

Controllers Replacement Considerations

The FT201XQ-R is available in tape and reel packaging instead of trays. The FT201XS-R offers the same functionality in an SSOP-16 package.
