I am designing a custom PCB using STM32F722RET6. How to connect the VREF+ pin(13) on the SMT32F722RET6?.
As per the hardware development manual, it says
"The VREF+ pin can be connected to the VDDA external power supply"
and then, "VDDA=VDD and VSSA=VSS."
can I connect it to 3.3V external supply?
Welcome, @VKoga.1, to the community!
yes, you can connect it to VDD. Please also read the General PCB Design Guidelines with figure 51 in the datasheet.
