Your blog inspired me to update a long-forgotten page on EDN, Home-Made Digital Clock Keeps on Ticking. It's about a digital clock I built in college that's based on a National Semi MM5316 clock chip. You can download a PDF of the data sheet there.
Try your search and see if you have the MM5316. If you do, your scanned version is probably of better quality than mine. That scan was from a fuzzy photocopy made long ago.
I will do it tonight- I don't have the Adobe PDF reader here. Although I must say it doesn't look promising- I don't seem to have a National MOS data book- in amongst the multitude of others. Colour me disappointed.
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.
