Overview

The UMFT201XB-01 is a compact evaluation module for the FT201X USB to I2C bridge IC. It functions as a bridge between a USB 2.0 Full Speed port and an I2C slave interface, allowing easy integration of USB connectivity into existing I2C-based systems.

Why Choose This Part

The module features a small form factor that plugs directly into standard 0.1-inch pitch sockets, making it ideal for rapid prototyping. It handles the entire USB protocol on-chip, requiring no USB-specific firmware development for the target microcontroller.

Applications

USB to I2C Bridge
Allows a USB host to communicate with I2C slave devices like sensors, EEPROMs, or motor controllers.
Battery Charging Detection
Utilizes the FT201X internal logic to detect USB dedicated charging ports for high-current battery charging applications.
Legacy Migration
Provides a low-risk path for adding USB support to legacy microcontroller designs that only feature I2C interfaces.
System Monitoring
Enables PC-based diagnostic tools to read system telemetry directly over an I2C bus.
