Question

What is the peripheral (circuit label ) diagram of STM32L476RGT6U?

I'm working with STM Nucleo-L476. I want to mount the IC STM32L476RGT6U on my PCB. I got the footprint successfully; however, I'm unable to find the peripheral connection of the particular IC. I got the pin diagram clearly and know exactly where my sensor pins should be connected but what about circuit label peripheral means where R, C, L, crystal oscillator should be connected? I did not find any material related to this. Please help and provide a peripheral connection diagram.

    It is an LQFP-64 packaging.

    Pinout information is in the datasheet.

    CubeMX is a good resource for doing pinout allocation.

    Please let me know, where is the peripheral circuit diagram. I have seen these materials but where is the exact board-level diagram?

    Board schematics are available under CAD Resources on the product page.
    If that’s not it, not sure what you’re looking for. You linked a chip, not a board. All the peripheral pin linkages are in the datasheet.
