LPC-LinkII UCom Port (COM3) Driver

The LPC-LinkII UCom Port (COM3) driver helps Windows recognize the USB communication port associated with an NXP LPC-LinkII development interface, allowing compatible software to communicate through a virtual COM port. It is intended for developers and technicians who need to connect supported hardware to a PC for serial communication during embedded development or troubleshooting.

Key Features

• USB communication support: Enables Windows to identify the UCom interface and make it available to compatible serial applications.
• Virtual COM port access: Provides a numbered port that development tools or terminal software can select. Although this device is listed as COM3, Windows may assign a different number.
• Support for listed Windows systems: Driver packages may cover Windows 10, 8.1, 7, Vista, and XP; check the individual package for your operating system and architecture.
• Device recognition and setup: Installing the appropriate package can help resolve a missing-driver warning when the hardware is otherwise working correctly.

How to Install LPC-LinkII UCom Port (COM3) Driver

1. Check your Windows version. Confirm your operating system and whether it is 32-bit or 64-bit. For Windows 10/11 systems, note that Windows 10 is listed as supported here, while Windows 11 compatibility requires confirmation from NXP.
2. Choose a compatible package. Before starting your LPC-LinkII UCom Port (COM3) driver download for Windows, review the package details. Look for the latest version compatible with your setup, and use an official or trusted source when choosing a free download.
3. Prepare the files. Extract the downloaded archive if necessary. Follow any included instructions about when to connect or disconnect the LPC-LinkII hardware.
4. Install the driver. Run the supplied installer, if provided. For a manual installation, open Device Manager, locate the UCom interface or unidentified USB device, select Update driver, and browse to the extracted driver folder.
5. Verify the connection. Reconnect the hardware if instructed, then check Device Manager for the port and any warning icons. Select the assigned COM number in your serial application and use the communication settings required by your hardware.

Keep the driver updated when NXP provides a compatible release that addresses your needs. Before you update, review compatibility notes and retain a working installer if possible. A newer package is not automatically the best choice for older Windows versions.
