FT2232H-56Q-REEL

Controllers Overview

The FT2232H-56Q-REEL is a dual high-speed USB to UART/FIFO integrated circuit manufactured by FTDI. It supports USB 2.0 High Speed (480 Mb/s) and Full Speed (12 Mb/s) protocols, handling the entire USB protocol internally without requiring specific firmware programming. The device features two independent channels that can be configured as UARTs or FIFOs, with data rates up to 12 Mbaud for UART and 8 MB/s for FIFO. It operates on a 3.3V supply voltage within a -40°C to +85°C temperature range and is housed in a 56-pin VQFN package.

Controllers Feature Summary

• Dual-channel architecture supporting simultaneous independent operation of UART and FIFO interfaces.
• Integrated Multi-Protocol Synchronous Serial Engine (MPSSE) for simplified JTAG, SPI, I2C, and bit-bang designs.
• Hardware-based USB protocol processing eliminates the need for custom microcontroller firmware.
• Built-in 1.8V LDO regulator and clock multiplier PLL for efficient power management.

Controllers Applications

• USB-to-UART bridge modules for RS232/RS422/RS485 communication.
• High-speed parallel FIFO interfaces for FPGA and DSP data acquisition.
• In-circuit programming and debugging via JTAG and SPI protocols.
• Industrial automation controllers requiring reliable serial connectivity.

Controllers Procurement Notes

Verify the specific suffix 'REEL' indicates tape-and-reel packaging when sourcing components. Confirm the manufacturer is Future Technology Devices International Ltd. Ensure the part number matches the 56-pin VQFN footprint requirements for your PCB layout. Check RoHS compliance status if required for your manufacturing standards.

Controllers Selection Notes

Select this component when dual-channel high-speed USB connectivity is required without external firmware. Compare against the FT2232HL for LQFP-64 options if through-hole mounting is preferred. Consider the FT4232H if four channels are needed instead of two. Verify voltage levels match the target system's I/O requirements.

Controllers Part Context

This part belongs to the FT2232H series, representing FTDI's fifth-generation USB interface devices. It succeeds older models like the FT2232D by offering higher speeds and additional protocol support. The series is widely used in embedded systems requiring versatile serial communication capabilities.

Controllers Replacement Considerations

The FT2232H-56Q-TRAY is a tray-packaged equivalent of the same functional device. For different package types, consider the FT2232HL-REEL which uses an LQFP-64 package but maintains identical electrical characteristics.
