What this STM32F413ZHT6 brings to the bench
The 144-LQFP package (20x20 mm) gives you 114 I/O lines, making it a solid fit for industrial control panels, motor drives, or gateway boxes that need a bunch of sensors and actuators hanging off a single chip.
Peripheral mix — what is on the pins
The QSPI interface lets you attach a serial NOR Flash for code shadowing or data logging. The peripheral set also includes a DMA controller, PWM timers, a watchdog timer, and a brown-out detect/reset block. That brown-out detect is useful for keeping the system from corrupting Flash if the supply dips below the 1.7 V minimum operating voltage.
