The STM32F302VBT6: The Cortex-M4 core includes a single-precision floating-point unit (FPU) and DSP instructions, which offloads math-heavy control loops in motor drives and digital power conversion without an external coprocessor.
For dual-sourcing resilience, the STM32F302 family includes pin-compatible density variants (e.g., 64 KB and 256 KB Flash options) that share the same 100-LQFP footprint.
The STM32F302VBT6 is rated for a maximum core clock of 72 MHz. At this speed the Cortex-M4 FPU and DSP instructions execute single-cycle for many operations, which matters for time-critical control loops.
