Yes - it will be interesting to see which way the industry moves. I think we are facing more physical limitations and challenges than we ever have in the past and it would be amazing if the whole industry always picked the same way.
I know this isn't the theme of the article, Brian, but one can avoid--or at least postpone for a couple generations--many of these challenges by moving to FD-SOI at 28nm or 14nm. FD-SOI is Faster, Cooler, and Simpler than alternate processes and, because it is planar, doesn't require the different design and processing that FinFETs need.
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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
