Designing Custom Board from STM32MP157 Eval Board – Power Budget Estimation Help

Hi everyone,

 

Hi everyone,

I’m currently designing a custom board based on the STM32MP157FAC1 evaluation board, and as part of the process, I’m working to estimate the power budget for the design.

However, I’m finding it difficult to locate clear information on load current requirements in the STM32MP1 datasheet, likely due to the MPU’s complex architecture.

Does ST provide any power estimation tools or official guidelines to help calculate power consumption when transitioning from the evaluation board to a custom design?

Any advice or references would be greatly appreciated. Thanks in advance!
