Which MCU in STM32 family is the best selection for using SAR 16-bit ADC related project

[RongShengWang]

Questions:

1. How many STM32 families offer SAR 16-bit ADCs?

2. Which MCU in STM32 family is the best choice for using SAR 16-bit ADC related project with the lowest cost?

Thanks

Yes you can, but NUCLEO-H753ZG is cheaper ;).

Edited: it's the NUCLEO-H753ZI  But the hyperlink is correct!

Also, for the NUCELO-H753ZI, we have a lot of ADC examples here.

I can't find " NUCLEO-H753ZG" . But there is NUCLEO-H753ZI - when you searchNUCLEO-H753ZG on Google

Are they same?

What do ZG/ZI mean?

What do H753/H723 mean?

Thanks

[RongShengWang]

Thanks a lot

This is just a typo from my college @SofLit .

For the H753/H723, H is the Product type with H = High performance and 723/753 is the device subfamily. You can find it explained on the Ordering information of each datasheet of an MCU.

Hope you enjoy our support.

Best Regards.

There are two under H753

NUCLEO-H753ZI   and   NUCLEO-H7S3L8

What is the difference between the two?

Why NUCLEO-H7S3L8 costs $9+ more than NUCLEO-H753ZI?

Which one has the better noise immunity?

Thanks,

Rong

For the naming of the MCU, PLease refer to the Ordering information chapter of each MCU on a board. For the price it should be normal since the STM32H7S3 is the newest product on the STM32H7 Familly (just released on march 2024). 

This post became so long and we are not tooking anymore about the original topic. So please close it by selecting a best answer for it(using the accept as solution button). The best answer should be the comment that answer your original request. 

For your comming questions, you can add new posts to the ST Community and we will be happy to help.

You need to refer to the related datasheets to get the differences.

Please contact your local sales for that question.

For that question related to EMC / EMI please submit ols ticket: https://ols.st.com/

Thank you

SAR ADC in STM32H7S3 has ONLY 12-bit.

SAR ADC in STM32H753 has 16-bit.

We need 16-bit.
