Vref of STM32U585RIT6

YFANG.2 · ‎2024-04-07

The part STM32U585RIT6 do not have a reference power + pin.

How can I connect an external reference power to this Micro?

Thanks!

As you can see on the DS13086:

"VREF- and VREF+ pins are not available on all packages. When not available, they are bonded to VSSA and VDDA, respectively.

When the VREF+ is double-bonded with VDDA in a package, the internal voltage
reference buffer is not available and must be kept disabled."

Best Regards.
