What are the benefits of using LPBAM

[DK3]

Hi,

I'm using STM32U575I-EV and CubeMX.

Please tell me about benefits using lpbam in CubeMX.

I thought that if I properly set up the peripherals that support LPBAM on the "Pinout & Configuration" screen, I could do the same thing as LPBAM Scenario.

When is it better to use LPBAM Scenario ?

Best regards.

Hello @DK3 

Two major advantages result from using LPBAM subsystem mechanisms:

• Power consumption is optimized:

        Bus and kernel clocks are distributed only when needed.
        Most of the product parts can be shut down.
        Analog peripherals or oscillators are powered on only when necessary.

• CPU bandwidth is offloaded:

        Peripheral configurations are done by DMA instead of CPU.
        Data transfers are done by DMA instead of CPU.

For more details, I suggest you refer to this WIKI and the AN5645.

Best Regards.
