Tizen-enabled SOM [SDT-A7X2-M4]

Tizen-enabled System-on-Module (SOM) [SDT-A7X2-M4] is a gateway SOM based on Arm® Cortex®-A7 dual core and Arm® Cortex®-M4 core. Arm® Cortex®-A7 dual core is for high performance and Arm® Cortex®-M4 core is for real-time application performance. SDT-A7X2-M4 also provides 512MB DDR3L-1600 DRAM and 8GB eMMC NAND Flash.


SDT-A7X2-M4 uses Secure Element (SE) to provide high security. The modules support Arm Mbed Linux OS and Samsung Tizen, and can be directly connected to Arm Pelion and Samsung SmartThings.
