STM32G474RET6 VREF connection

flying_car · ‎2026-02-04

Hello,

I am planning to use the STM32G474RET6 and would like to confirm whether I can use the internal VREFBUF. This product's package is LQFP-64 and while reading the datasheet I noticed the note : ''The VREF+ pin is double-bonded with VDDA on some packages''. Could you verify whether the internal reference voltage can be used with this package?

Thanks.
