Samsung’s ARTIK™ Module is a highly integrated module for
secure Internet of Things (IoT) devices that require Wi-Fi. It is
based on an ARM® Cortex® R4 core with on-chip memories,
an ARM® Cortex® M0+ core, a complete 2.4GHz Wi-Fi Phy,
MAC layer processing, a large complement of standard digital
buses including audio (I2S), and power management. The
module is packaged with additional external Flash memory, a
hardware Secure Element and a single integrated 2.4GHz
structural antenna.
The application processor is fully available for applications
since the Wi-Fi stack, through the MAC layer, is handled by a
co-processor. Aimed especially at power-sensitive devices
needing Wi-Fi, the CWAM210S Module provides excellent
performance in a variety of environments, with a feature set
tailored specifically for IoT end nodes.
