Decoupling & Vcc Pin Configuration for STM32 MCUs

Chubs
Associate III

Hello Community,

Reaching out to you for feedback on the attached configuration for Vcc on my new STM32 based DAQ board.

My objective was to reduce the inductance to the Vcc pins of the MCU (STM32G0B0RET6 64 LQFP package). Hence I clubbed three pins:

A) VBAT

B) VREF+

C) VCC

Altogether & decoupled them as attached in the following layout. Now it makes sense to do this, however are there any obvious aspects that I might've missed here? Your insights would be invaluable!

I plan to use the ADC on board in some future cases, apart from that mostly everything is
