72 MHz Cortex-M4 with on-chip analog — what this MCU delivers
The STM32F301K8U7TR is a 32-bit ARM Cortex-M4 microcontroller running at 72 MHz, with 64 KB of Flash program memory and 16K x 8 of SRAM.
Where it fits — mixed-signal control in industrial and light-duty automotive
The STM32F301 targets applications that need a DSP-capable Cortex-M4 core with real-time analog I/O on a single chip: motor-control feedback loops (PWM + ADC), sensor conditioning with the 12-bit ADC, and analog output generation via the 12-bit DAC.
