Power Up a STM32H757IIT6

[taj]

I’m designing a minimal breakout board for the STM32H757IIT6 to power it up and access a few GPIOs. The purpose is purely learning both about the STM32 dual-core system and PCB design. Since I’m a beginner, I’d like suggestions on anything essential I should include to reliably power up the MCU and reduce the chance of errors on the PCB.

Hello @taj and welcome to the community;

 

I recommend you referring to Getting started with STM32H74xI/G and STM32H75xI/G MCU hardware development application note and precisely "9 Recommended PCB routing guidelines for STM32H74xI/G and STM32H75xI/G devices".

This application note is intended for system designers who develop applications based on the STM32H750 Value line, STM32H742, STM32H743/753, STM32H745/755, and STM32H747/757 lines, and who need an implementation overview of the following hardware features:
• Power supply
• Package selection
• Clock management
• Reset control
• Boot mode settings
• Debug management.

 

I hope this help you.

Thank you.
