FT2232H-56Q MINI MDL

Overview

The FT2232H-56Q MINI MDL is a compact evaluation module featuring the FT2232H dual-channel USB interface IC. It supports USB 2.0 High Speed (480 Mbps) and provides two independent channels configurable as UART, FIFO, or MPSSE interfaces. The module operates on a 3.3V supply and functions within an industrial temperature range of -40°C to +85°C. It utilizes a 56-pin VQFN package footprint for the host controller. This design facilitates rapid prototyping for applications requiring simultaneous serial communication, data buffering, or JTAG/SPI programming via standard USB connections.

Feature Summary

• Dual-channel architecture enabling independent configuration of each port for distinct protocols such as UART, FIFO, or MPSSE.
• Supports USB 2.0 High Speed connectivity with backward compatibility for Full Speed and Low Speed devices.
• Integrated MPSSE engine allows direct control of synchronous protocols including JTAG, SPI, and I2C without external logic.

Applications

• FPGA configuration and debugging via JTAG interfaces.
• High-speed data acquisition systems requiring FIFO buffering.
• Prototyping multi-port serial communication solutions.

Procurement Notes

Verify the specific revision suffix and manufacturing date code against the current FTDI datasheet to ensure component availability and compliance with RoHS directives. Confirm that the mini-module form factor matches the target PCB layout requirements, as pin assignments are fixed by the integrated FT2232H controller design.

Selection Notes

Select this module when dual independent serial or parallel interfaces are required from a single USB connection. It is suitable for designs needing flexible protocol support across two channels. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range and that the 3.3V power supply meets the current consumption specifications outlined in the official electrical characteristics.

Part Context

This mini-module integrates the FT2232H chip, part of the FTDI H-Series family known for high-speed USB-to-serial conversion. Unlike the larger LQFP packages, the 56-pin VQFN variant offers a reduced footprint while maintaining full functionality. The mini-module format serves as a reference design and evaluation tool for engineers developing embedded systems requiring robust USB connectivity.
