Great MCU but really like the Harmony story too

Hey Max, I really liked the features of the MCU too, great core performance, 28Msample/s ADC, crypto engine, and field upgradability via 2MBytes of internal flash, but I was also excited by MPLAB Harmony effort that Microchip co-announced with the 'MZ 32.

This is an Integrated Software Framework for PIC32 that essentially integrates the licensing, resale, and support of both Microchip as well as third-party middleware, drivers, libraries and RTOSes.

I like this bringing together of an ecosystem so developers don't have to spend half their time looking for compatible code and paying licence fees and get off the ground quicker - big deal these days (or any day).

I agree -- in fact that's right at the top of my list of columns to write and post -- it comes just after fighting all of the fires that are surrounding me :-)

you better watch out max! You'll end up in the never ending cycle of persuing the next biggest/fastest thing and never even get that bot off the ground!

Glad Microchip decided to join the party

I am glad that Microchip has actually started to do something with their 32bit line of products.  FOr the longest time, they were not really all that great compared to their dsPIC line of products.  I still am hoping that they might decide to come out with something that has a FPU on it.  As for their claim as the fastest 32bit device, I will have to dig into that a bit more.

It certainly isn't the fastest 32-bit MCU. While it might outperform Cortex-M4 when not using floating point, it has caches and doesn't run from flash. So it should be compared to Cortex-R4/R5, which run at much higher frequencies (Samsung SSDs use 3 at 400MHz) and have better IPC as well.

What does faster mean really in this contest?  Should we consider ARM7 and ARM9 as microcontrollers, in which case this Microchip's product would pale into insignificance? We should consider performance per Watt, performance per Dollar among other factors such as software eco-systems, security of supply etc. It's not just about an arbitrary CoreMark number alas....

Targeting IoT market?

Microchip's new 32-bit connectivity MCU might well be targeted for the IoT applications where power is not a problem. The features look interesting. I would like to evaluate how the DSP engine along with 159 additional DSP-centric instructions helps in improving the performance of the MIPS microAptiv Core.

Let me know when you've done that evaluation ... it would make a great article :-)

How come this be the fastest 32 bit MCU at 200MHz??

I'll ask the folks at Microchip to comment
