N6 peripherals compatibility to other STM32 / H7 ?

Heyho,

just found that the N6 has gigabit ethernet - which might help me staying away from the monstrous MPUs... :D

Is there kinda compatibility list between the STM32 families for the peripherals?

  • ethernet interface, surely different HW concerning GbE vs 100M, but maybe the registers / descriptors work basically the same?
  • CANFD and the SAIs?
  • OCTOSPI / XSPI with memory-mapped HyperRam? 
  • the (partly) more simple peripherals like ADC, timers, UART?

Merci!

Hello,

Not obvious to provide an exhaustive list of peripherals compatibility between N6 and H7.

Generally speaking, new products feature either the same previous versions of the peripherals from older products, or newer versions with new features or completely new architecture features which is the case of the Eth.

For ADC, Timers, UARTs most probably they are the same, may be with a slight difference in term of triggers and connections with other DMAs. 

I think better, to speed up your findings, is to look at the first chapter "main features" in the RMs of each peripheral description and compare + do a comparison of register mapping at the end of the chapter.

More generally, it would be useful to have this across all families for all the IP blocks.

I think @waclawek.jan has brought this up before ...

 

PS:

Might be a good question to ask the new ST Sidekick AI agent ...

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
