STM32F3 in STM32 Family
The STM32F3 series by STMicroelectronics is a family of 32-bit mixed-signal microcontrollers based on the ARM Cortex-M4 core with Floating Point Unit (FPU) and DSP instructions. Positioned as a high-performance analog alternative to the mainstream F1 and F4 lines, these MCUs integrate advanced analog peripherals such as fast 12-bit ADCs, precise DACs, and ultra-fast comparators. They are engineered for applications requiring high-speed data acquisition and precise control loops in compact embedded systems.
Variants in This Sub-Family
Variants within the STM32F3 family are primarily distinguished by their specific analog peripheral density and package size. The F303 line offers the highest performance and peripheral richness, while the F301 and F302 lines provide cost-optimized solutions with fewer features. Specialized variants like the F334 include high-resolution timers specifically for digital power applications, and the F373 incorporates 16-bit Sigma-Delta ADCs for high-precision sensing requirements.
