Product Summary

The Universal Serial Bus hub PDIUSBD11D is a cost and feature-optimized USB interface device. The PDIUSBD11D is used in microcontroller-based systems and communicates with the system microcontroller over the high speed I2C serial bus. This modular approach to implementing USB functions allows the designer to choose the optimum system microcontroller from the available wide variety. The PDIUSBD11D is ideally suited for computer monitors, docking stations, keyboards, and many other applications that use the I2C or the SMBus-based architecture.
