STM32F3 High-Performance ARM® Cortex™-M4 MCUs

STMicroelectronics STM32 F3 Mixed-Signal MCUs combines a 32-bit ARM® Cortex®-M4 core (with FPU and DSP instructions) running at 72MHz with a high number of integrated analog peripherals leading to cost reduction at the application level and simplifying application design. Peripherals include ultra-fast comparators, op-amp with programmable gain, 12-bit DACs, ultra-fast 12-bit ADCs, precise 16-bit sigma-delta ADCs, core coupled memory SRAM, 144MHz advanced 16-bit pulse-width modulation timer, and high-resolution timer. It also includes a flexible interconnect matrix that allows autonomous communication between peripherals and saves CPU resources and power consumption. A high degree of compatibility with the STM32 F0 series guarantees outstanding efficiency when designing derivatives of applications at different performance levels.
