FT4232H-56Q-TRAY

Controllers Overview

The FT4232H-56Q-TRAY is a USB 2.0 High-Speed (480 Mb/s) to Quad UART/MPSSE bridge controller manufactured by FTDI. It integrates four independent interfaces within a VQFN-56 package, supporting data rates up to 480 Mb/s on the USB bus and asynchronous serial transmission up to 12 Mbaud. The device operates on a single 3.3V supply with a voltage range of 1.62V to 3.63V and consumes approximately 70 mA of operating current. It functions across an industrial temperature range from -40°C to +85°C. The component supports multiple interface protocols including UART, FIFO, JTAG, SPI, and I2C, eliminating the need for specific USB firmware programming.

Controllers Feature Summary

• Integrates four independent channels configurable as asynchronous UART or synchronous MPSSE engines
• Handles complete USB protocol processing internally without requiring external microcontroller firmware
• Supports hardware flow control and modem interface signals for reliable serial communication
• Includes built-in clock generator and programmable baud rate generation capabilities

Controllers Applications

• Converting USB connections to multiple independent RS232/RS422/RS485 serial ports
• Implementing USB-to-JTAG, SPI, or I2C interfaces using MPSSE engine modes
• High-speed data acquisition systems requiring FIFO buffering
• Embedded system debugging and programming interfaces

Controllers Procurement Notes

Verify the specific suffix 'TRAY' indicates tray packaging rather than reel configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the VQFN-56 package dimensions match the target PCB footprint. Check moisture sensitivity level requirements for assembly processes. Validate that the 3.3V logic levels align with the host system design.

Controllers Selection Notes

Select this component when four independent serial or synchronous interfaces are required from a single USB connection. Compare against FT2232H if only two channels are needed or FT4232HAQ for automotive temperature grades. Consider the VQFN-56 package constraints for thermal management and board space. Verify driver compatibility with the target operating system environment before finalizing the design.

Controllers Part Context

This part belongs to the FT4232H series, representing FTDI's fifth-generation USB devices. It serves as a bridge between USB hosts and various serial peripherals. The standard variant differs from the automotive-grade FT4232HAQ in temperature rating and qualification standards. It is commonly paired with evaluation modules like the FT4232H-56Q MINI MDL for rapid prototyping.

Controllers Replacement Considerations

FT4232HL-REEL offers identical functionality but in a 64-LQFP package with reel packaging. FT2232H-56Q-TRAY provides dual-channel capability in the same VQFN-56 package. FT4232HAQ-TRAY is the automotive-qualified version with extended temperature ranges.
