The USX2016-NU-01 is a USB 2.0 hub controller manufactured by SMSC Corporation (Standard Microsystems Corporation, now Microchip Technology). It functions to extend the number of USB ports available in a host system. These controllers are vital for scenarios where the native USB ports are insufficient to accommodate all connected peripherals.

Applications

• PC Motherboards
• Laptop Docking Stations
• Standalone USB Hubs
• Embedded Systems
• Industrial Control Systems

Features

• Compliant with USB 2.0 specifications.
• Supports high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) data transfer rates.
• Integrated USB transceivers for efficient data communication.
• Typically features 4 downstream USB ports.
• Includes per-port over-current protection to prevent damage from faulty devices.
• Supports both bus-powered and self-powered modes of operation.

Benefits

• Increases the number of available USB ports, enabling the connection of more peripherals.
• Offers flexible connectivity options for various USB devices.
• Safeguards the hub and connected devices from over-current situations.
• Streamlines USB connectivity by consolidating multiple devices through a single hub.
• Provides options for power management, adapting to different system requirements.

Additional Details

The USX2016-NU-01 is typically packaged in a QFP or similar surface-mount package. External components such as crystal oscillators and passive components are required for correct operation. Specific details, including the number of downstream ports and power consumption, can be verified by consulting the official datasheet from Microchip Technology (formerly SMSC). Careful implementation is necessary to adhere to USB specifications and ensure robust performance.
