Nuvoton's Gerda IC and Qt for MCUs: A Breakthrough in Human-Machine Interfaces

On November 5, 2026, a remarkable collaboration between Nuvoton Technology Corporation Japan and Qt Group has set new standards in the creation of graphical user interfaces (GUIs) for various applications. Introducing the Gerda™ IC, this HMI (Human-Machine Interface) controller platform delivers premium graphical interfaces without relying on external memory, thus catering to the economics of high-volume production.

The Gerda™ IC is set to transform key areas such as automotive displays and home appliance interfaces by enabling an array of advanced features. With its ability to support high-resolution graphics, smooth animations, and interactive touch capabilities, Gerda™ is engineered to meet the growing demands of industries transitioning towards more sophisticated user experiences. As software-defined vehicles evolve and connected appliances increase in prevalence, the expectation for responsive, visually appealing interfaces is more significant than ever.

Efficiency without Compromise

What makes the combination of the Gerda™ IC and Qt for MCUs particularly compelling is the powerful integration that eliminates the complexities typically associated with GUI development. The comprehensive component library and advanced graphics engine provided by Qt for MCUs allow development teams to craft visually stunning and intuitive interfaces efficiently. By leveraging the extensive built-in RAM of the Gerda™ IC alongside Qt’s optimization capabilities, developers can achieve a reduction in memory footprint while delivering high-performance user experiences.

Equipped to function independently without the necessity for external memory, Gerda™ facilitates an economical solution that can lower both component counts and total system costs. This is increasingly vital for products produced in large batches where manufacturing expenses directly influence market competitiveness.

The Rising Standard of Over-the-Air Updates

The trend toward connected devices comes with the necessity for software updates, especially in the automotive sector. Over-the-air updates for features and GUI enhancements are becoming standard. The collaboration between Nuvoton and Qt for MCUs responds to these demands, ensuring that developers can introduce changes and new features seamlessly even after product launch. As a result, businesses can stay agile and responsive to user feedback and advancing technology.

Gerda’s security features align perfectly with the requirements for safe and efficient updates, providing peace of mind for manufacturers and end-users alike. The integrated development environment supported by Qt offers ready-made GUI components and facilitates a smooth partnership between design and software engineering teams, further streamlining workflows from conceptualization to execution and testing.

Insights from Industry Leaders

Yoshihide Kanakubo, Vice President of Battery and Automotive Business Group at NTCJ, emphasized the growing significance of user experience: “The quality of the user experience has become a key differentiator for modern products. By combining Gerda™ with Qt for MCUs, customers can deliver premium graphical user experiences while balancing performance, memory efficiency, and system cost.”

Furthermore, Michele Rossi, Director of Qt MCUs Product Management at Qt Group, pointed out the historical challenges facing Interface developers: “For years, the choice of a microcontroller was between an interface people enjoy using and a system cost the product could carry. That trade-off is what we set out to remove.” With this new partnership, the market now has access to a means of offering users high-quality interfaces, made possible with hardware tailored for high-volume production.

Conclusion

The collaboration between Nuvoton's Gerda™ IC and Qt for MCUs is a significant milestone in the advancement of user interfaces across multiple industries. By bringing together top-tier technology that addresses both functionality and cost-efficiency, Nuvoton and Qt are paving the way for the next generation of smart devices. As we move forward into an age where connectivity and UX dictate market success, the importance of innovations like these will only continue to grow.
