Overview

The FT4232HL is a USB 2.0 High Speed (480Mb/s) to UART/MPSSE IC featuring four independent channels. Two of these channels can be configured as Multi-Protocol Synchronous Serial Engines (MPSSE), allowing for the emulation of JTAG, SPI, and I2C protocols directly from a USB host.

Why Choose This Part

This bridge IC eliminates the need for complex USB firmware development by handling the entire USB protocol on-chip. Its high-speed 480Mbps interface and flexible MPSSE engines provide significantly higher throughput and lower latency than standard Full-Speed USB-to-serial converters.

Applications

USB to Quad UART
Enables a single USB port to control four independent RS232, RS422, or RS485 serial interfaces with data rates up to 12 Mbaud.
Integrated Debug Port
Commonly used on development boards to provide a simultaneous JTAG/SWD interface for programming and a UART interface for terminal logging.
USB to SPI/I2C Bridging
Utilizes the MPSSE engines to communicate with sensors, EEPROMs, and flash memory directly from a PC application.
Legacy Peripheral Upgrading
Provides an efficient path for upgrading industrial equipment with multiple serial ports to modern USB connectivity.

Getting Started

For rapid prototyping, engineers often use the FT4232H Mini Module. Development requires the FTDI D2XX drivers for custom protocol implementation or Virtual COM Port (VCP) drivers for standard serial communication.

Also Consider

FT2232HL-REEL FTDI - A dual-channel version of the same architecture, ideal for designs that only require two serial or MPSSE interfaces.
