KYOTO – November 05, 2026 -- Nuvoton Technology Corporation Japan (NTCJ) and Qt Group (Nasdaq Helsinki: QTCOM) have added Nuvoton's Gerda HMI controller platform as target hardware for Qt for MCUs, enabling premium graphical interfaces without external memory.
Built-in RAM removes external memory from the bill of materials
Gerda's large built-in RAM and its display, connectivity and control interfaces allow standalone HMI systems with no external memory. Qt for MCUs' graphics optimization and Gerda's texture compression shrink the GUI memory footprint. The companies say the result is a lower component count and lower total system cost, which matters most in high-volume products.
Target applications range from automotive and motorcycle instrument clusters and head-up displays to home appliance display panels. The companies demonstrated a motorcycle instrument cluster and a washing machine interface.
Over-the-air updates become a design requirement
The companies point to software-defined vehicles, connected appliances and two-wheelers as drivers of over-the-air feature and GUI updates. Qt for MCUs' development environment and Gerda's security features support secure updates, so developers can change interfaces and add features after a product ships. Memory costs continue to weigh on system budgets, according to the release.
Tooling targets shorter GUI development cycles
Qt for MCUs combines an integrated development environment, ready-made GUI components, the QML language, simulation and agentic AI skills. Nuvoton and Qt say the toolchain streamlines work from design through implementation and verification and helps teams build applications in less time and at lower cost.
Yoshihide Kanakubo, Vice President of the Battery and Automotive BG at NTCJ, said user experience quality has become a key differentiator, and that customers can now balance performance, memory efficiency and system cost.
Michele Rossi, Director of Qt MCUs Product Management at Qt Group, said teams can build the interface users expect on "hardware priced for high-volume production."
