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 w...

During the summit it was stated that all unanswered Q&A questions would be copied to this thread and answered. Is that not still the case?Thanks.

Hi there!I'm reporting a general documentation error for all instances of the STM32 CORDIC hardware.For the modulus parameter m, the documentation lists the following:But this is not correct. The hardware supports the range [-1,1] for the modulus val...

Hi ST!I am writing to ask if any ST MCU's will be released with 2x independent FMAC units?At the moment, doing stereo audio processing with a single FMAC is problematic (and ST MCU's ONLY have a single FMAC unit), especially being unable to load the ...

The STM32U5 has HS PHY and it's slower than the STM32H5 so why doesn't the H5 have HS PHY or any HS USB support? Will a version that does be released in future? Its almost the perfect chip to use for a future project I have in mind aside from the lac...

@STTwo-32 still waiting on an update for this please.

@ManishNair you are after the MP1 or MP2 series for that type of thing.Microcontrollers simply don't have the speed and performance to handle that much data. The H7 is for a different purpose. Gigabit doesn't fit the intended use cases of these produ...

Absolutely it can. The CORDIC has a specific function for just that purpose. But you'll need to pipeline your operations to get the best performance. The chip specific documentation from ST covers this directly. Just read the CORDIC section thoroughl...
