FT245RQ-TRAY

Controllers Overview

The FT245RQ-TRAY is a USB to parallel FIFO bridge controller manufactured by FTDI. It implements the USB 2.0 Full Speed protocol with a data rate of 12 Mb/s. The device operates on a supply voltage range of 1.8V to 5.25V and draws a typical supply current of 15mA. It is housed in a 32-VFQFN package with exposed pad, measuring 5x5 mm. The component supports an operating temperature range from -40°C to +85°C. This specific tray-packaged variant is designated as obsolete and no longer manufactured.

Controllers Feature Summary

• Provides a bridge interface converting USB signals to parallel FIFO data for microcontroller integration.

Controllers Applications

• USB to parallel data acquisition systems
• High-speed serial-to-parallel conversion interfaces

Controllers Procurement Notes

This part number is officially obsolete and no longer manufactured by FTDI. Verification of availability requires checking secondary market distributors or authorized surplus suppliers. Engineering teams should review the Product Change Notification (PCN) regarding obsolescence dated March 1, 2024, and assess long-term supply risks before finalizing designs.

Controllers Selection Notes

Designers requiring active inventory should consider alternative FTDI USB-to-FIFO controllers such as the FT245RL or FT245RN series. Selection must account for package differences, as the FT245RQ uses a 32-QFN form factor while other variants may utilize SSOP or TQFP packages. Ensure the replacement part matches the required voltage range and thermal specifications for the target application environment.

Controllers Part Context

The FT245RQ belongs to the FTDI R-CHIP family of USB interface ICs. It serves as a single-channel Full Speed USB controller designed for applications requiring high-throughput parallel data transfer. The 'TRAY' suffix indicates tube packaging, distinct from the reel packaging found in other variants like the FT245RQ-REEL.

Controllers Replacement Considerations

Public confirmed substitute part numbers include FT240XQ-R and FT245RNQ-REEL. Engineers must verify pin compatibility and software driver support when migrating from the obsolete FT245RQ to these alternatives.
