Brown-out detect, POR, and a programmable watchdog are on-chip — the sort of supervision that saves an external reset supervisor in cost-sensitive BOMs.
This is a mainstream STM32L4S part, so second-source equivalents are not officially cross-referenced, but the STM32L4S family shares pin-compatibility across density options in the same package — good for dual-sourcing planning if you qualify the adjacent Flash/RAM variants.
It uses an ARM Cortex-M4 core with FPU running at up to 120 MHz.
