The ML51 is a Flash embedded 1T 8051-based microcontroller. The instruction set of the ML51 is fully compatible with the standard 80C51 with performance enhanced and low power consumption. The ML51 runs up to 24 MHz at a wide voltage range from 1.8V to 5.5V, and contains up to 64/32/16/8 Kbytes Flash called APROM for programming code. The ML51 Flash supports In-Application-Programming (IAP) function, which enables on-chip firmware updates. The ML51 includes an additional configurable up to 4/3/2/1 Kbytes Flash area called LDROM, in which the Boot Code normally resides for carrying out the In-System-Programming (ISP). - For more information, please visit Nuvoton Technology Website: https://bit.ly/3hVdcmC buy now: https://direct.nuvoton.com/en/low-power-ml51-series/ contact us: SalesSupport@nuvoton.com #Product #Learning #Basic #en 0:00 簡介 0:20 Agenda 0:45 NuMicro Product Portfolio 1:28 2019 Brand New MCU Platform 2:06 ML51/ML54/ML56 Series Portfolio 3:29 ML51 Series Low 4:50 NuMicro Naming Rule 6:06 NuMicro® ML51 Features 8:19 4 Different Power Modes 10:44 Low Power Mode Features • Wake up resource: WKT, ACMP, GPIO 12:37 Low Power VS Battery Life 13:28 ADC 15:00 Comparison of 8-bit Products Feature 17:13 Fire Fighting System 21:30 Battery Management System (BMS) 22:30 Gaming Phone 23:36 Development Board 24:13 Development Environment

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

This video is going to show you our latest Low power ML51 series microcontroller. The ML51 platform features high performance and pin-to-pin compatibility with our 32-bit microcontrollers, such as M480, M031, and M261 series . ML51 series supports up to 24MHz operation frequency, and 1.8V to 5.5V operating voltage, it provides four power modes: normal run mode, low power run mode, low power idle mode, and power down mode. In power down mode with multiple wake-up sources. The power consumption in low power idle mode is down to 13 μA and in power down mode it is less than 0.8 μA. When the clock runs at internal RC oscillator can also allow 9600 baud rate for UART communication. ADC supports up to 8 channels of 12-bit ADC, analog comparator and five levels of the internal reference voltage, ML51 provide two channels of PDMA, strong immunity like 8 kV ESD and 4.4 kV EFT. - For more information, please visit: http://www.nuvoton.com buy now: NuMaker-ML51PC/ http://direct.nuvoton.com/numaker-ml51pc NuTiny-ML51EB9AE/ http://direct.nuvoton.com/nutiny-ml51eb9ae contact us: SalesSupport@nuvoton.com #Product #Learning #Basic #en
