Overview

The FT2232H-56Q-REEL is a high-speed USB 2.0 to dual-channel multipurpose UART/FIFO IC. It utilizes the FTDI Multi-Protocol Synchronous Serial Engine (MPSSE) to simplify synchronous serial protocol designs like SPI, I2C, and JTAG at speeds up to 30Mbps per channel.

Why Choose This Part

This 56-pin VQFN variant provides a compact 8x8mm footprint for space-constrained designs while maintaining dual-channel flexibility. It supports 5V tolerant I/O and features an integrated 1.8V LDO regulator, reducing the total bill of materials for 3.3V systems.

Applications

High-Speed USB to JTAG
Converting USB signals to dual JTAG interfaces for FPGA programming and processor debugging.
Industrial USB to RS-485/RS-422
Implementing robust long-distance serial communication links with minimal external logic.
Legacy Peripheral Migration
Updating older FIFO or 8-bit parallel bus designs to modern USB 2.0 High Speed standards.
USB to Fast Serial Optical Interface
Interfacing high-speed optical data links to a PC via the synchronous FIFO mode.
