Nuvoton Technology Corporation presents three major themes of reference applications incorporating newly launched microcontrollers with ARM Cortex-M0/ M4/ M23, and ARM9 cores. The three themes are: Industrial Control, IoT Security, and Smart Home Appliances. Industrial Control includes factory remote data collecting, environment monitoring, smart number recognition, and interactive Human Machine Interface (HMI) Solution. IoT Security includes USB FIDO key for identity security and fingerprint secure IoT door lock. Smart Home Appliances include intelligent power outlet. Industrial Control – incorporating NuMicro NUC980, N9H20, M480, NDA102 microcontrollers Nuvoton Industrial Control reference applications include: 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. IoT Security – incorporating PSA Certified Level 1 Arm Cortex-M23 Based NuMicro M2351 microcontroller Nuvoton IoT Security includes: 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 and more.
Nuvoton M2351 is a secure microcontroller platform powered by ARM Cortex-M23 core with ARMv8-M architecture, TrustZone technology, security technologies, peripherals and tools. The ultra-low-power 32-bit microcontroller works in low voltage range from 1.62V to 3.6V and can operate at up to 48 MHz frequency, with up to 512 Kbytes embedded Flash memory in dual bank mode supporting OTA firmware update and up to 96 Kbytes embedded SRAM. It is suitable for applications such as IoT secure connections, fingerprint authentication, EMV card reader, security alarm system, smart home appliance, wireless sensor node device (WSND), auto meter reading (AMR) and portable wireless data collector.
The M2351 series is equipped with 32 Kbytes Secure Boot ROM as root of trust, multiple firmware programming tools by In-System Programming (ISP), In-Circuit Programming (ICP) and In-Application Programming (IAP). In addition to TrustZone software protection mechanism, it also supports eXecution Only Memory (XOM), LDROM (user program loader) and multiple cryptographic hardware accelerators which are used to protect the core software and data assets on a microcontroller system. The M2351 series also integrates a 8 COM x 40 SEG controller with internal charge pump for segment LCD panel and provides high performance connectivity peripheral interfaces such as UART, SPI, I²C, GPIOs, USB and ISO 7816-3 for smart card reader.
