choose of a MCU

Jad · ‎2024-10-11

Good morning.

I used the CUBEMX board selector because I wanted an MCU with many ADC. I chose the U family because it was written that it has 25 ADC and one CAN.

Unfortunately, I did not find these ADC while using the wizard. I only saw 3. how could i get more?

best regards

Hello,

You are confusing the number of channels and the number of ADC instances.

Each ADC has many ADC channels it could be up to 25 depending on the MCU part number.

The number of ADC instances is provided in the datasheet:

1 x 12 bit and 2 x 14-bit. The number of the channels depends on the package.

But in CubeMx I think there is a mistake: ADC total (Converters) needs to be equal to 3.

I'm getting back to you to confirm the issue.
