Do you know I can find the symbol and the footprint of the renesas R5F5631PDDFL PLQP0048KB-A for KiCad software ?
Have you already found KiCad library for your device? Your device is a 48pin LFQFP package type. Maybe you can try creating the footprint and symbol yourself or find a footprint that's compatible.
