Hi everyone, I'm Aaron. The FAE of Nuvoton technology. Today, I'm glad to show you the Nuvoton secure development board, NuMaker-IoT-M2354. The NuMaker-IoT-M2354 is an IoT evaluation board powered by the NuMicro® M2354 series. Before the introduction of NuMaker-IoT-M2354, I will take you to a quick understanding of NuMicro M2354. The M2354 is the latest NuMicro IoT series product which is based on Arm® Cortex®-M23 CPU core technology. The TrustZone® technology based on Armv8-M architecture is a CPU system-wide approach to microcontroller security. The M2354 series carry 1 Mbytes embedded Flash memory and 256 Kbytes SRAM. It's essential for IoT devices with real-time OS requirements. And you can focus on software development without warring about the flash and SRAM resource. The M2354 series is equipped with plenty of peripherals. In addition to providing UART I2C SPI Timer, it also supports the Quad SPI, USB FS OTG, and CAN BUS. Furthermore, to satisfy the IoT device's display development, the M2354 series built-in 8 COM x 40 SEG LCD controller drives up to 320 dots to meet various smart home and IoT appliances. In addition to providing many peripherals, the critical feature of M2354 is supporting many security functions. The secure boot ensures the legality and integrity of the running firmware. The hardware crypto with RSA/ECC/AES/SHA accelerators can help the device connect to the cloud fast and safely. Moreover, the M2354 is equipped with Key Store, which could be used with crypto accelerators to enhance the chip security level. To comply with Arm PSA CertifiedTM Level 3, the M2354 has implemented some countermeasures to protect against non-invasive attacks like side-channel attacks or fault injection attacks. The NuMaker-IoT-M2354 equips a Bosch environmental sensor, BME680, which contains temperature, humidity, barometric pressure, and VOC gas sensing capabilities. After getting data from the sensor, users can send data to the cloud, such as Pelion or AWS, by Mbed OS. Because M2354 supports hardware crypto, the data can be sent more efficiently and safely. The data could be shown on the LCD panel by the LCD library provided in the M2354 BSP. The NuMaker-IoT-M2354 contains a Wi-Fi module and LoRa module for wireless applications. Depending on the data throughput and power consumption, you can choose one of them for your IoT applications. In the LoRa network, each node is not connected but must be connected to the gateway before being linked back to the central host, or data can be transmitted to another node through the central host. For example, if choosing the LoRa module for the cloud development, you could use NUC980 LoRa Gateway for your gateway platform. The NuMaker-IoT-M2354 supports the radio frequency band of the LoRa module on 915MHz and 433MHz, depending on the customer's requirement. In addition to providing the rich peripheral, the NuMaker-IoT-M2354 also equips the Arduino UNO connector and mikroBUS™ connector for flexible applications. Suppose you want to develop other wireless connecting features like 4G-LTE or NB-IoT. In that case, the Nuvoton also provides a UNO-to-PCI adapter board to supports Quectel EC21 4G/LTE and Quectel BG96 NB-IoT modules. The NuMaker-IoT-M2354 also provides multiple power supplies by external power connectors and an ammeter connector that can instantly measure power consumption. In addition, the Nu-link2-Me on the board is a debugger and programmer supporting development on Keil, IAR, GCC, and Mbed IDE. #en #Learning #Basic #Application #Product - Online Purchase Development Tools： ● M2354 Series https://www.nuvoton.com/products/microcontrollers/arm-cortex-m23-mcus/m2354-series/index.html ● NuMaker-LoRa-NUC980 https://www.nuvoton.com/products/iot-solution/lora-platform/ ● NuMaker-M2354 https://direct.nuvoton.com/tw/numaker-m2354 ● Quectel-BG96A https://direct.nuvoton.com/en/quectel-bg96a ● Quectel-EC21A https://direct.nuvoton.com/en/quectel-ec21a - For more information, please visit Nuvoton Technology Website: https://bit.ly/3hVdcmC buy now: https://direct.nuvoton.com/ contact us: SalesSupport@nuvoton.com

Secure Smart Metering Communication Reference Design Hi everybody, today we are going to introduce a reference design of Smart-Metering communication card based on NuMicro M2351 Series microcontroller. You can find useful security features based on the Arm Cortex-M23 CPU core with Nuvoton’s in-house technology integration. The auto-metering is an infrastructure for automatic, remotely, wire or wireless meter data reading. It’s highly possible to be intervened if there is no security mechanism. That is a very typical IoT security issue in the IoT era. In many countries, there are a lot of Auto-Metering Infrastructure (AMI) projects being undertaken by main electricity power companies worldwide. Most projects start from upgrading the communication modem cards as the first step rather than retiring the meters. The modem card can play as a gateway to monitor the incorrect device operation and data transmission security. Issues of modem card security are covering: First, a limited performance due to crypto computation efficiency Second, speed limitation due to interface choice The third, cost burden due to extra hardware modules for different communication protocols Nuvoton’s reference design of Secure Smart Meter Communication is an end-to-end security solution for AMI. With the collaboration with SPI-Korea, the solution incorporates a lot of advantages such as TrustZone security for firmware, a range of interfaces for device communication, secure over-the-air firmware update, and remote management. With the complete hardware specification of M2351, a security software company, SPI-Korea, can easily implement their secure AMI solution for modem card which connects meters and cloud servers. M2351 also contributes the crypto acceleration during the cryptographic computing in order to save CPU time for different communication protocol modules by its powerful hardware functionalities during message transmission outside of a microcontroller unit. SPI-Korea has developed a range of Armv8-M TrustZone based technologies. Her expertise covers Boot Manager, Key Manager, and Device Manager, which is very useful for microcontroller security and certainly shows the stability of a microcontroller device. Also, they are certified by Korea Electricity Company. We hope this successful experience can be further adopted in other areas worldwide because it’s a secure, accurate and environmentally safe solution for AMI. This slide is a picture for SPI-Korea AMI modem card design. NuMicro Family microcontrollers can be utilized for designs of auto-metering infrastructure devices. We start from AMI modem card and we are confident to support meters of any next-generation of AMI. We now integrate M23-based microcontroller with M4-based or Arm9-based microcontroller as a proposal for next-generation modem card of Korea AMI and we hope to provide high-performing cost-effective solution for all AMI devices in the future. - For more information, please visit Nuvoton Technology Website: https://bit.ly/3hVdcmC contact us: SalesSupport@nuvoton.com
