The choice between STM32H753VI and STM32H753ZI isn’t a trade-off in CPU performance or core features, it’s about package and pin availability. The ZI variant, with a larger package like LQFP144, makes full peripheral access possible and simplifies design for demanding applications, while the VI variant is compact and cost-effective for less I/O-intensive use cases.
