The Avnet Azure Sphere MT3620 Modules support Microsoft’s Azure Sphere end-to-end solution for highly secured, Wi-Fi connected Microcontroller (MCU) devices. The production-ready, certified modules come in two versions: an on-board chip antenna module for cost-optimized systems and an external U.FL antenna module supporting two external antennas for applications requiring higher performance, external antennas. Both modules are pin and footprint compatible, allowing for easy design migration and end-product enhancements.
By integrating all the necessary support and RF front end circuitry onto the small 33 mm x 22 mm module, Avnet has reduced the design time for implementing Sphere-based solutions. More importantly, developers can leverage the modules wireless certifications (pending) for their end product, saving considerable certification costs and testing time.
The Azure Sphere MT3620 modules are based on the MT3620AN SoC, which supports dual-band 802.11 a/b/g/n Wi-Fi connectivity, a 500 MHz Arm® Cortex™-A7 core for user applications, and two general purpose 200MHz Arm Cortex-M4F I/O subsystem cores designed to support real-time requirements. The on-chip peripherals (GPIO, UART, I2C, SPI, PWM and ADC) can be mapped to dedicated I/O pins on the module for connection to external sensors, I/O connectors, or other user application circuits.
Microsoft’s end-to-end security, OTA update service, and userfriendly Visual Studio development environment add significant value when compared to traditional MCU solutions.
For development with these Avnet modules, Avnet’s Azure Sphere MT3620 Starter Kit (based on the chip antenna version Azure Sphere MT3620 module) provides extremely versatile expansion options using a wide-range of inexpensive add-on boards to facilitate rapid prototyping and fast time-to-market.
