Connectivity is everything these days. If you canít talk to the outside, itís hard to make a compelling case for a product. Devices need to be connected either to the Internet, to an intranet, or some other outside medium. Component makers have gotten much better simplifying this process. One example is the latest 32-bit MCU family announced by Microchip. The companyís 24-member PIC32MZ Embedded Connectivity (EC) family offers a performance level of 330 DMIPS and 3.28 CoreMarks/MHz.
Note that the inclusion of a 10/100 Ethernet MAC, a Hi-Speed USB MAC/PHY, and dual CAN ports help support those communications applications. The family also offers a broad set of wired and wireless protocol stacks. Thatís combined with a full-featured hardware crypto engine with a random number generator for high-throughput data encryption/decryption and authentication, a key for applications that need to communicate.
The PIC32MZ is Microchipís first MCU to employ Imaginationís MIPS microAptiv core, which adds 159 new DSP instructions that enable the execution of DSP algorithms at up to 75 percent fewer cycles than the PIC32MX families. This core also provides the microMIPS instruction-set architecture, which improves code density while operating at near full rate.
The first 12 members of the family are expected to sample in December, with the remainder coming by sometime next spring. Pricing starts at $6.68 each in 10,000-unit quantities.
You're right, Rob. Security will be an Achilles heel for the Internet of Things. I mentioned this a few days ago and I'll say it again: In 2012, Mitt Romney's election campaign set up a special "clean room" where their most important computers couldn't get hacked. Their solution was simple and virtually foolproof: The computers were not connected to the Internet. That speaks volumes about the real solutions to security issues.
Mydesign: I didn't specifically mention IoT when I wrote that piece, but it was definitely on my mind. It's come up more and more lately. In fact, I'm writing a piece on that topic as we speak, so stay tuned.

Richard, connectivity is very important. Now a day's self talking devices are gaining momentums in market and this has been achieved through IoT (Internet of Things) and last mile connectivity.
There is currently much discussion around the term "platform," which may be preceded by the adjectives "mobile," "wearable," "medical," "healthcare," etc. However, regardless of the platform being discussed, they usually have one key aspect in common: They tend to be wireless. So, why is this one aspect so fairly universal? The answer is convenience.
Everyone has a MEMS story. For most of us itís probably the airbag that saved our lives or the life of a loved one. Perhaps itís the tire pressure sensor that alerted us about deflation before we were stranded alone on a dark muddy road.
Bioimimicry is not merely a helpful design tool -- it also encourages designers to think not only about how to solve design problems by imitating nature, but how to make the products, materials, and systems they design more ecologically sound and nature-friendly.
