Where are the VDDA/GNDA pins in the STM32F205RG?

Hello,

I'm using the STM32F205RG chip (WLCSP64 package)

This chip has no dedicated pins for VDDA/GNDA. Are these connections shared with a specific VDD/GND pin? If so which one?

The goal of my question is to make a nice ground separation for analog and digital and improve ADCs/DACs performance.

Cheers,

Simon

But it does have dedicated Vcap1 & Vcap2 pins. See Figure 19 in the data sheet.

Cheers, Hal
