Advice on choosing the right STM32 for high ADC sample rate and large RAM

[Magal]

Hi everyone,

For my current project, I am working with an STM32WB55RGV. I am using all 256 KB of its RAM and running the ADC1 at a sample rate of 5.8 MSPS with 8-bit resolution.

I am looking to migrate to a newer STM32 family that provides equivalent (or more) RAM and supports this high ADC performance. I plan to order some standalone chips and devkits for prototyping. Compact devkits would be a huge plus.

During my research, I found the STM32H523CCT6 chip and the NUCLEO-H533RE devkit at a good price. Do you think this is the best choice for my needs? Also, are there other "mini" devkit options (like the Nucleo-32) that come with a large amount of RAM?

Thanks in advance!
