A short guide on IoT Microcontroller chip selection

IoT Microcontroller Chip Selection The IoT structure is comprised of the edge nodes, the gateway nodes/hubs, and the cloud/datacenter. The interface between the virtual, digital world of the Internet or local network, and the real, analog world is provided by the edge nodes. An edge node is the "thing" in the IoT. Based on the type of application, the edge node can gather and/or receive sensed data, process and transmit it to the network. Hence, the functionality of the edge node can be described in terms of its integrated microcontroller and the associated transducers, interfaces, processing and communication to the network. The IoT microcontrollers(MCU) with Ultra Low Power (ULP) are the computing engines that powers the edge of the Internet of Things (IoT). The ‘things’ living on the edge utilize Microcontrollers (MCUs) to handle user interfaces, collect and transmit sensor data, and provide security features. Hence, the application developers are challenged with a number of optimization challenges to ensure the very low power operation over periods of years and decades. The MCU market has a strong relationship with the IoT trend, as the small nodes used for connectivity, and sensor hubs to collect and log data, are primarily based on MCU platforms. The IoT related MCU market is predicted to reach US $2.8 billion in 2019. Security – Inarguably a prime factor to c...
