The STM32F303 are mixed-signal MCUs with an Arm® Cortex®-M4 core (with FPU and DSP instructions) running at 72 MHz.
These are the superset devices in the STM32F30x series.

The devices are equipped with:

  • Up to 7x fast- and ultra-fast comparators (25 ns)
  • Up to 4x Op-Amp with programmable gain
  • Up to 2x 12-bit DACs
  • Up to 4x ultra-fast 12-bit ADCs with 5 MSPS
  • Up to 3x fast 144 megahertz motor control timers (resolution < 7 ns)
  • Full-speed USB and CAN 2.0B communication interfaces
  • Core Coupled Memory SRAM (Routine Booster), a specific memory architecture boosting time-critical routines, accelerating the performance by 43% compared to Flash execution

The STM32F303 microcontrollers operate from 2 to 3.6 Volts.
Memory ranges from 32 to 512 Kbytes and packages from 32 to 144 pins.
Temperature range from -40 to 85° C or from -40 to 105° C (with a junction temperature of 125° C).
