STMicroelectronics STM32F3 High-Performance ARM® Cortex™-M4 MCUs

STMicroelectronics STM32F3 High-Performance ARM® Cortex™-M4 MCUs are based on the ARM® Cortex™-M4 32-bit RISC core operating at a frequency of up to 72 MHz, and embedding a floating point unit (FPU), a memory protection unit (MPU) and an embedded trace macrocell (ETM). The family incorporates high-speed embedded memories (up to 256 Kbytes of Flash memory, up to 48 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses. The devices offer up to four fast 12-bit ADCs (5 Msps), up to seven comparators, up to four operational amplifiers, up to two DAC channels, a low-power RTC, up to five general-purpose 16-bit timers, one general-purpose 32-bit timer, and two timers dedicated to motor control.

  • 72 MHz/62 DMIPS (from Flash) or 94 DMIPS (from CCM-SRAM*) Cortex-M4 with single cycle DSP MAC and floating point unit
  • Real-time performance
    • CCM-SRAM* (core coupled memory): 8 Kbytes of SRAM mapped to the instruction bus; critical routines loaded in the 8-Kbyte CCM at startup can be completed at full speed with zero wait states, achieving 94 Dhrystone MIPS and CoreMark score 155 at 72 MHz
