Cortex-M4 at 72 MHz — where the throughput lands
The STM32F302C8T6 runs an ARM Cortex-M4 core with single-precision FPU at 72 MHz — enough headroom for a sensor-fusion loop reading three 12-bit ADC channels and executing a PID filter inside 10 µs without cycle-counting. The 64 KB on-chip flash and 16 KB SRAM leave room for a modest RTOS kernel plus application stack; a typical motor-control firmware with Hall-sensor commutation and UART logging fits in about 40 KB of flash.
Peripheral mix for industrial and sensor interfaces
The 11-channel 12-bit ADC and single 12-bit DAC handle multi-sensor acquisition and analog output without an external converter. DMA and PWM peripherals offload the core for time-critical tasks like waveform generation or stepper-motor pulse trains.
