Is the STM32H7 intended to replace F7 family? I want to start a design and considered the F7 family but will it disappear when the H7 is in full production?
I doubt it, the variety of parts allows for price stratification, and attack different markets.
The 400 MHz speed makes it competitive against the ATMEL/MICROCHIP CM7 parts which have been 300 MHz FPU-D since inception.
Also publically committed to the STM32F7 thru January 2027

Hello John F. ,
The STM32F7 and STM32H7 are two distinct families. They will coexist on the market.You can pursue your design based on our STM32F7 device without concerns.
We know that the ST will not stop producing STM32F7 that have already been released. The question is: Will all future cortex-m7 releases be in the STM32H7 family? Or will there be new releases in the STM32F7 family as well?
We are providing different STM32F7 lines offering various features.Shall I understand that you have a particular use case that can not be realized using the STM32F7 MCUs already existing on the market?
I hope for a STM32 for high-end Motor control and digital power convertion. Something like the STM32F303/334 but using a cortex-m7 core and with ethernet peripheral. STM32H7 do the job, but it is very expensive and complex for that.
Thanks Clive and Khouloud for the quick replies and helpful information.
as far as I can see, the H7 will drop in on an existing F7 PCB.
I checked the 208pin LQFP, and every pin looks good. FMC pins, Ethernet MII, USB Device/Host, Spi,IIC,Uarts,DSI all line up, pin for pin.
The STM32F7 family is a large portfolio covered by the 10 years longevity comittment as advertized by ST for the whole STM32 family so there is absolutely no issue to start a new design with any member of this series. The many STM32 series are based upon different technology nodes depending on the objectives that are targeted for the given series, be it the performance, be it the low power consumption or any other combination. On the high performance path, the STM32H7 platform will see some other variants proposed in the future to expand the offering.
Multi-core, DSI and SWV that works? SDMMC seems a bit marginal at times, much more touchy at 4-bit than F7 implementation, perhaps related to change in IP for DDR/UDR? Documentation that lacks a good technical editor?
Core/process seems viable to 500 MHz, so head room there.
I wish ST would be more forward in their presentation about what is happening about the H7, seems like the abandoned step-child 18 months in here.
I read in a chinese presentation something like a dual-core 480MHZ M7 + 240MHZ M4 for next H7. So the H7 should only grow to higher-ends.
