I would agree with Mr. Nenni 100% on that. I checked with several sources and found that it was highly unlikely that TSMC shut down 28-nm production. I reported this in the EE Times Forum, also in March:
The point of mentioning this rumor in the story was to support the statement that TSMC has been dogged by rumors about it's 28-nm process.
Mr. Nenni of SemiWiki has been saying since March that the 28nm rumors about TSMC shutting down production were false, http://www.semiwiki.com/forum/content/1091-tsmc-absolutely-did-not-halt-28nm-production.html
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.
