STM32F411C minimal wiring?

BSchm.6 · ‎2023-05-03

Hi,

I'm currently moving a project from STM32F446 to an STM32F411CEU and stumble upon some strange things in the wiring which is not known from the F446.

So from the manual it is not clear to me how to deal with the VCAP_1 and PA0-WKUP inputs.

So my question: is there some documentation/schematic available that shows the minimal wiring of the 48-pin F411? I know there are some eval-boards out there but their schematics are far away from being "minimal".

Thanks!

Hi @BSchm.6 ,

Looking for documentation, you need to refer to AN4488: Getting started with STM32F4xxxx MCU hardware development.

Basically supplies, ALL

VCAP single pin 4u7 or 2u2 on each. Expect to see 1.25V on them when working.

Pull BOOT0 LOW

And then whatever programming interface you use.

OK. And how about VREF+ (when no VREF- is available?) Connect with 3.3V?
