FT2232H-56Q-TRAY

Controllers Overview

The FT2232H-56Q-TRAY is a dual-channel USB-to-UART/FIFO interface controller manufactured by Future Technology Devices International Ltd. It supports the USB 2.0 High-Speed standard with a maximum data rate of 480 Mbps. The device integrates two independent channels capable of operating as UARTs or FIFOs, housed in a compact 56-pin VQFN package measuring 8x8 mm with a height of 0.9 mm. It operates on a single 3.3V power supply and functions within an industrial temperature range of -40°C to 85°C.

Controllers Feature Summary

• Dual-channel architecture supporting simultaneous independent operation of two ports
• Integrated USB 2.0 protocol engine eliminating the need for external firmware development
• Supports multiple interface modes including UART, high-speed FIFO, and MPSSE for synchronous serial protocols

Controllers Applications

• USB-based instrumentation and measurement devices
• Industrial control systems requiring robust serial communication
• Smart card readers and barcode scanners
• Portable storage devices and multimedia players

Controllers Procurement Notes

Verify the specific suffix 'TRAY' indicates tray packaging when sourcing components. Confirm that the 56-pin VQFN variant matches the required footprint, distinct from the legacy 64-pin LQFP version. Ensure compatibility with the intended operating system drivers for Windows, Mac, or Linux environments.

Controllers Selection Notes

Select this component when space constraints necessitate a smaller footprint compared to the standard 64-pin LQFP version while maintaining dual-channel functionality. Consider the FT4232H if four independent UART channels are required instead of two. Verify that the host system can support the necessary USB 2.0 High-Speed bandwidth requirements.

Controllers Part Context

This part belongs to the FT2232H series, representing a pin-compatible, reduced-footprint evolution of the original 64-pin LQFP design. It retains the core functionality of the family while optimizing board space through the 56-pin VQFN package. It serves as a direct upgrade path for designs previously utilizing larger packages without changing logical interface capabilities.

Controllers Replacement Considerations

The FT2232H-56Q-REEL offers identical electrical characteristics but utilizes reel packaging instead of trays. For applications requiring four channels, the FT4232H-56Q-TRAY is the appropriate alternative within the same package family.
