Nuvoton Technology Corp., a leading microcontroller platform provider, was the direct exhibitor at Embedded World 2019 in Nuremberg, Germany, an exhibition that took place in February this year. Nuvoton presented there three major themes of reference applications incorporating newly launched microcontrollers with Cortex^®-M0/ M4/ M23, and ARM9 cores. These three themes were: Industrial Control, IoT Security, and Smart Home Appliances. Industrial Control included factory remote data collecting, environment monitoring, smart number recognition, and interactive Human Machine Interface (HMI) Solution. IoT Security included USB FIDO key for identity security and fingerprint secure IoT door lock. Smart Home Appliances included intelligent power outlet.

Nuvoton Industrial Control reference applications included: Remote Terminal Unit, Smart Number Recognition, Interactive HMI Solution, and DALI-2 Digital Lighting Control. Industrial Remote Terminal Unit adopts ARM9 based NuMicro^® NUC980 series microcontroller. The NUC980 series operates up to 300 MHz and has internal crypto accelerators as well as Ethernet. It could be used for factory monitoring and automation control with Wi-Fi/ 4G LTE/ NB-IoT modules. Smart Number Recognition adopts Arm^® Cortex^®-M4 based NuMicro^® M480 series microcontroller. This demo captures water, electricity, and gas meter numbers, using machine learning neural network algorithms to identify. The information can be transmitted to the cloud through Wi-Fi or NB-IoT to realize the auto meter reader function after the identification. Based on the experience with clients, the demand for interactive HMI is increasing. Therefore, Nuvoton released N9H20/30, M480 series microcontrollers, and free emWin graphics software tool. Nuvoton provides HMI solution to help clients save development time and complete interactive graphics interface with high quality and efficiency. DALI-2 Digital Lighting Control adopts Arm^® Cortex^®-M0 based NuMicro^® NDA102 series microcontroller. The solution is based on Digital Addressable Lighting Interface (DALI) technology. This solution includes certified DALI-2 library built by Nuvoton.

Nuvoton IoT Security included: Arm^® Pelion Secure IoT Device Management supported by M2351, USB FIDO Key for Identity Security, and Fingerprint Secure IoT Door Lock. The NuMicro^® M2351 series is one of the first Arm^® Cortex^®-M23 based MCUs that has been Platform Security Architecture (PSA) Certified™ Level 1. The Platform Security Architecture keeps the system secure from booting to operating, also keeping data and codes secure. The Pelion IoT Platform is a flexible, secure, and efficient foundation spanning connectivity, device, and data management. It accelerates the time to value of your IoT deployments by helping you easily connect trusted IoT devices on global networks, invisibly administer them, and extract real-time data from them to drive competitive advantages. The Fast Identification Online (FIDO) Identity supported USB Flash memory drive with dual security features of the NuMicro^®M2351 microcontroller and SunASIC^® fingerprint sensor module, compliant with the Universal 2nd Factor (U2F) protocol. It could be applied to identity identification applications.

Smart Home Appliances included Intelligent Power Outlet and OLED Display Solution. Intelligent Power Outlet shows Nuvoton's versatile technical capabilities. This reference design uses the emWin engine based HMI, incorporating the TFT LCD touch screen input to control the power switches of AC and USB outlets. The power station's screen shows the real-time current and power consumption of every turned-on power outlet. The ON/OFF state is also available on a remote cell phone. OLED Display Solution is based on NuMicro^® M480 series which controls a 2" OLED display and plays GIF on the screen. M480 series operates up to 192 MHz with 160 KB embedded SRAM. The high-performance microcontroller decodes GIF motion graphics smoothly. In addition, the library has built-in fonts. Users can load various font libraries through the Nuvoton font conversion tool.
