The STM32 F3 series of microcontrollers combines a 32-bit ARM Cortex-M4 core with a DSP and FPU instructions running at 72 MHz with advanced analog peripherals for more flexibility. This series innovates in embedded DSC design by combining a Cortex-M4 core with fast 12-bit 5 MSPS and precise 16-bit sigma-delta ADCs, programmable gain amplifiers (4 gains, 1% accuracy), fast 50 ns comparators and versatile time control units running at 144 MHz, giving optimum integration.
The STM32 F3 series allows designers to tackle mixed-signal control applications. The devices are optimized for efficient handling and processing of mixed signals in circuits such as 3-phase motor controllers, biometrics and industrial sensor outputs or audio filters. They help simplify design, cut power consumption and reduce PCB size in consumer, medical, portable fitness, system monitoring and metering applications.
Pin compatible with the STM32 F1 series, the new STM32 F3 series enlarges the STM32's Cortex-M4 portfolio which now offers both entry-level cost with the F3 series and highest performance with the F4 series.
