Q1
Which household appliance typically consumes the most electricity during summer?
-
Robotic vacuum cleaner
-
Television
-
Microwave oven
-
Air conditioner

Q2
Why are some stores still able to supply eggs during a shortage?
-
They have larger stores
-
They have multiple sources of supply
-
They have more employees
-
They operate longer hours
正解！
When one supplier encounters disruptions, having multiple supply sources helps reduce the risk of shortages. This is the core concept of supply chain resilience.
In 2025, Nuvoton continued to strengthen supply chain resilience, promote responsible procurement, and advance a sustainable supply chain. Key achievements included:
- Nuvoton 100% adopted smelters certified by the Responsible Minerals Initiative (RMI) organization
- 93% of major suppliers published ESG reports
- 100% of major suppliers passed ISO 14064 or equivalent international standards verification
- Major suppliers have achieved a 20% reduction in greenhouse gas emissions compared with the 2021 baseline year.
- By adjusting procurement specifications for PVC cling film, there has been an annual reduction of 36.29 kilograms in CO2e emissions.
Nuvoton continues to strengthen supply chain resilience and responsible procurement practices. For more information, please visit サプライヤ管理.

Q3
Which of the following is one of the most important factors affecting a smartphone's power consumption?
-
Chip power
-
Phone color
-
Brand name
-
Packaging material
正解！
The chip is one of the key factors affecting power consumption in electronic products. Lower chip power consumption helps extend battery life and reduce energy consumption throughout a product's life cycle.
Nuvoton continues to develop low-power products that help customers achieve energy-saving goals. The low-power, high-performance NuMicro® M2L31 series microcontroller incorporates multiple power-saving modes in chip design. Compared to the previous generation NuMicro® M253 series, the M2L31 has achieved a substantial reduction in unit operating power consumption from 130 μA/MHz to 60 μA/MHz, achieving an energy efficiency enhancement of 54%. The maximum operating frequency has been upgraded to 72 MHz.
Nuvoton continues to develop high-performance, low-power products and improve energy efficiency through technological innovation. For more information, please visit グリーン製造.
