Carte IoT Azure Sphere MT3620

Azure Sphere provides three levels of security technology:

• 1.Secured MCU: Secured from the silicon up. The new MT3620 crossover class of MCUs combines for the first time both real-time and application processors with built-in Microsoft security technology and connectivity.
• 2.Secured OS: An OS built for security and agility to create a trustworthy platform for new IoT experiences. Our secured OS builds security innovations pioneered in Windows into an HLOS small enough for MCUs.
• 3.Cloud Security: Protect devices with a cloud built for IoT security. The Azure Sphere Security Service renews device security, identifies emerging threats, and brokers trust between device, cloud, and other endpoints.

About Azure Sphere MT3620 Development Kit:

Azure Sphere MT3620 Development Kit is specially designed to support rapid prototyping and to enable developers to experience Azure Sphere technology. MT3620 is the first Azure Sphere certified MCU. Azure Sphere certified MCUs are a new class of secured, connected crossover microcontrollers. MT3620 features three user-accessible microcontroller cores: one ARM Cortex-A7 core and two general purpose ARM Cortex-M4F cores. The MT3620 is designed to support real-time requirements when interfacing with a variety of on-chip peripherals including GPIO, UART, I2C, SPI, I2S, PWM and ADC. It has a built-in security subsystem with its own dedicated CM4F core for secure boot and secure system operation, along with dual-band 802.11 b/g/n Wi-Fi.

Please note that the current Azure Sphere software release does not support all features of the MT3620 hardware, including the two general purpose ARM Cortex-M4F cores, some peripheral interfaces (ADC, I2C, I2S, PWM and SPI), Wi-Fi 802.11a, and RTC with clock selection and battery backup. For ADC and I2C, customers can use MT3620 Grove Shield board, which has a UART to I2C chip and a I2C12-bit ADC chip.​

The Azure Sphere operating system is pre-installed on the MT3620 and is designed to work with the Azure Sphere Security Service to create a secured IoT platform. 

MT3620 software development is supported using the powerful Microsoft Visual Studio IDE:​
Install Visual Studio (Support Community, Enterprise or Professional) and the Azure Sphere extension, plug the development board into a PC over USB, and start developing IoT applications with unprecedented levels of security.
To use the MT3620 Dev Board for Azure Sphere, you’ll need a Windows 10 PC with the latest Windows Updates, along with Azure Sphere software development kit (SDK). 

Important notes:
- It's nécessaire to manualy update the Azure Sphere and the SDK to the lastest version (18.11.1) while you run the card for the first time. This update add security fixes and new features. This up^date is only available via the SDK and can't be realised in OTA (Over The Air). Release Notes for Azure Sphere.


- Il est nécessaire de mettre à jour manuellement la carte Azure Sphere ainsi que d'installer le dernier SDK (version 18.11.1) lors de la première utilisation. Ceci permet principalement de disposer des derniers correctifs de sécurité et de profiter de nouvelles fonctions. La mise à jour pour Azure Sphere est uniquement manuelle via le SDK et n'est pas disponible en OTA (Over The Air). Voir les notes de publications des mises à jours.
 
- this development board can only be used for prototyping. It can not be integrated into a product for commercial distribution. It can not be resold or used in a production environment.
 
- For a commercial project, it is necessary to request Microsoft via the online tools in order to get an Original Design Manufacturer.
 
- this product is subject to marketing and use restrictions. A license agreement is to be accepted and signed by the end user in order to comply with this regulation.
