Overview

The FT2232HL-REEL is a high-speed USB 2.0 to dual-channel UART/FIFO bridge IC capable of handling data rates up to 480 Mbits/s. It features two independent interfaces that can be configured for various serial or parallel protocols, such as JTAG, SPI, I2C, or bit-bang modes via its Multi-Protocol Synchronous Serial Engine (MPSSE). This chip is widely used for adding high-bandwidth USB connectivity to embedded systems and as a bridge for programming FPGAs and microcontrollers.

Why Choose This Part

This IC offers a highly integrated solution with a built-in 1.8V LDO regulator and an on-chip clock multiplier PLL, reducing external component count. Its 5V tolerant I/Os and wide operating temperature range from -40degC to 85degC make it suitable for robust industrial environments. The dual-channel architecture allows for simultaneous operations, such as debugging via one port while transmitting data over the other.

Applications

FPGA Programming and Debugging
Utilizing the MPSSE to implement JTAG interfaces for loading bitstreams and debugging high-speed FPGA designs.
High-Speed USB to UART Bridge
Providing two independent high-speed serial ports for system logging and command-line interfaces.
USB to Fast Parallel FIFO
Interfacing with external logic or microcontrollers to transfer large datasets at high speeds via the 4KByte Tx/Rx buffers.
USB to SPI/I2C Gateways
Creating custom PC-based tools to interface directly with peripheral ICs for testing or configuration.

Getting Started

To begin development, engineers often use the UM2232H-B evaluation module to test the chip's various modes. FTDI provides D2XX direct drivers and VCP (Virtual COM Port) drivers, along with comprehensive C++ and Python libraries for controlling the MPSSE. An external EEPROM can be added to customize USB descriptors and device IDs, though the IC functions with default settings for standard UART modes.
