STM32N6 and general MCU questions.

[etheory]

There was discussion of a new 20nm process with more reliability and a new MCU created using it that would be released.

Is this the STM32N6?

What ARM Cortex M-series will the N6 be? M55 or M85?

Will there be an M85 line at some point? What clock speed will it go up to?

Will there ever be a 1GHz H7 line to compete with the NXP 1GHz M7 i.MX RT1170 Crossover MCU range?

Will there be a faster M33 line (I'm thinking 300MHz to match the NXP i.MX RT600 Crossover MCU series)?

Will there be a dual-core M33 line in the performance series?

Are you considering adding a dedicated FFT processor that can run synchonously with the MCU?

Are you considering adding a math coprocessor like the NXP PowerQuad for synchonous complex/trig/fft/matrix math?

Thank you!

Hello Luke,

thank you for your interest in STM32 products and thank you for all your questions.
Let me try to answer some of them.
The incoming STM32N6 is not based on the announced technology, but another one. 
Yes, there will be STM32 products series based on CM-85. Stay tuned to learn more already during 2024.
The clock speed will clearly be increased to the region >500MHz and attacking 1GHz.
The STM32 roadmap will bring lot of new and highly competitive products, full of innovative IP's, efficient architecture and state of art, in-house, technologies.
Sorry, we can't disclose more now, but surely we'll be informing all STM32 users in the right time.

Have a nice day,
Roman

Thanks @Roman LUDIN I appreciate the limitations of what you can tell me, but the above is definitely heading in the direction I was hoping, so thank you very much for that.

It is now public and available at distributors : https://www.st.com/stm32n6

Thanks for the update! That's amazing news.

No M85? Will there be an M85 option coming? The M55 is a nice option compared to an M7 but the M85 is significantly faster and more capable.

What about LQFP packages? Are they coming also?

Thanks!

[Miguel CASTRO]

It will be no LQFP packages in the STM32N6 family. 
Regarding CM85 we cannot comment :)

[etheory]

That's incredibly disappointing to hear that there will be no LQFP packages since it means DIY projects with this chip are basically impossible if they are BGA-only. Are there any hobbyist friendly packages on the horizon? Even maybe QFN?

r.e. CM85, it's fine, you don't need to comment here, you already did at the STM32 Summit last week where you said that there will me a CM85-based product but it "wouldn't be ready any time soon".

Thanks.

Hi @Miguel CASTRO , @etheory and @Roman LUDIN 

Thank you very much - STM32N6 is a hugely exciting development - particularly with its MIPI CSI-2 support - very few μCs provide this.

Are there any reference implementations or other information on using STM32N6 with image sensors - perhaps with ST's range of image sensors?

Wishing you all a great Christmas and all the best for 2025!

Will
