What the 100 MHz Cortex-M4 and 512 KB Flash mean for your BOM
The STM32F411VEH6U is an STMicroelectronics ARM Cortex-M4 MCU in the STM32F4 family, clocked at 100 MHz with a single-precision FPU that handles DSP and control loops without a separate coprocessor. The 100-UFBGA package (7x7 mm) keeps the board area tight, but the fine-pitch BGA means a four-layer PCB with microvias is the practical floor for routing the 81 I/O and USB OTG signals.
The internal oscillator means you can bring up the core without an external crystal for cost-sensitive builds, though the USB OTG peripheral will still want a precision clock source for full-speed operation.

Peripheral set — what is on-chip
The 16-channel 12-bit ADC covers analog inputs like current-sense or thermistor readings.
Package considerations for the BGA variant
The 100-UFBGA (7x7 mm) is a 0.5 mm pitch BGA. That footprint saves board space versus a 100-pin LQFP, but it demands a solder-mask-defined pad and a stencil aperture sized for the ball diameter. Reflow profile follows the standard JEDEC MSL rating — no special bake if the sealed moisture-barrier bag is intact. For rework, a bottom-side preheat at 150°C and a focused hot-air nozzle on the BGA body lifts the part cleanly; the 7x7 mm body is small enough that thermal gradient across the package is manageable.
