Keyoke, they very much are blurring the line. What is considered high end mcu like the Cortex-M4 I used to consider to be a CPU. However, CPU's like desktops still use distributed RAM, external drives, everything isn't integrated into a single package. I consider an MCU to be resource constrained!
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
