Hi, Max. Thanks for detailing Spansion's announcement.

Here's the background in case if anyone missed it:

Spansion Exec Reassures Fujitsu Customers


http://www.eetimes.com/document.asp?doc_id=1320210

The stuff Spansion didn't detail in its press relesae is this:

Spansion's proprietary eCT technology goes inside embedded MCUs by 2015

Impressive range. What about pricing?

I can hardly see what is specific to IoT business. Any idea ?

My understanding is that the M3 and M4-based MCUs, although extremely powerful and efficient, may be overkill (and consume too much power) for a lot of IoT applications. The C0+ based MCUs are more applicable to a wide range of IoT applications.

Thanks Max. That means that CPU throuput is far less critical than connectivity.

Well... I guess it sort of depends. Like many people, when I hear "IoT" I tend to think of hundreds of millions (billions, in the not-so-distant future) of teeny-weeny devices (small processors coupled with sensors and/or actuators) connected to the internet. In this case, connectivity and low power consumption will often trump raw processing power (the Cortex C0+ MCUs will score here).

However, the IoT isn't restricted to teeny-weeny devices -- there will be lots of other devices that are physically larger and/or do require more processing power (the Cortex M3/M4 MCUs will score here).

So I think Spansion's point of view is that the fact they offer 700+ processors spanning the M0+, M3, and M4 cores means they can address a wire range of IoT  applications.

interesting interpretation of the FM acronym, flexible micontrollers...I think 99% people think frequency modulation...I would think every microcontroller is flexible by definition...and intersting enough they make 700 of them, so they are not that flexible after all!

@krisi: interesting interpretation of the FM acronym...

I might have known you would have a comment about that (LOL)

Did I ask you if you are planning on going to EE Live! 2014?

I was trying to wrap my mind around this MCU and figured that perhaps it was for use with the new wraparound displays that phones are sporting.  Silicon?  No, sillycon putty.

Krisi, They mean flexilbility at their factory , when they limit the capabilities of each unit and then sell it under a different number.

Of all the exhibits in the Pre-Apocalypse Era Museum, Breek was always in awe of the unearthed details and true-to-scale reproduction of a technological creation space that the long gone humans had once inhabited.
