I am looking for pin to pin compatible chipset from both STM32H7 & STM32L4 series.

As per my comparison the STM32H743ZI - LQFP144 and STM32L4R5/R7ZI - LQFP144 finds pin to pin compatible. please suggest your feedback

    As H7 needs some VCAP capacitors and L4 has a sepaerate VDDUSB rail, H7 and L4 are nor pin compatible. If you really want to put either L4 or H7 on your board, you need to carefully design comatibilty by externel places parts.
