Microsoft Azure Sphere Module V3

Comprehensive IoT Security

The AES-MS-MT3620-M-G-3 is a small form-factor, tri-core Wi-Fi SoC module, intended for use as a secure Wi-Fi client, in internet-connected IoT applications. Avnet’s production-ready, certified module comes fitted with a dual-band chip antenna and is ideal for secure applications in 2.4 GHz or 5GHz Wi-Fi networks. Based on the MT3620AN SoC, this is a new class of connected SoC IoT device that facilitates “end-to-end security”. User applications can target it’s 500 MHz ARM Cortex-A7 core as well as two general purpose 200 MHz ARM Cortex-M4F I/O subsystem cores designed to support real-time requirements. The on-chip peripherals (GPIO, UART, I2C, SPI, I2S, PWM and ADC) can be mapped to any of these three user-accessible processor cores.
