STMicroelectronics STM32 F3 Series of MCUs

STMicroelectronics’ STM32 F3 Series of MCUs combines the 32-bit ARM Cortex-M4 core with a DSP, FPU instructions and advanced analog peripherals.

The series combines 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 time control units running at 144 MHz. The devices are optimised for efficient handling and processing of mixed signals in circuits such as three-phase motor controllers, biometrics and industrial sensor outputs or audio filters, allowing designers to tackle mixed-signal control applications.

The devices help simplify design, cut power consumption and reduce PCB size in consumer, medical, portable fitness, system monitoring and metering applications.

STM32 F3 Series Mixed-Signal MPUs are pin compatible with the STM32 F1 series, and the STM32 F3 series enlarges the STM32’s Cortex-M4 portfolio to now offer both entry-level cost with the F3 series and highest performance with the F4 series. The STM F3 Series includes devices with 64 to 256 KB of on-chip Flash memory, up to 48 KB of SRAM and is available in WLCSP66 (<4.3 x 4.3 mm), LQPF48, LQFP64, LQFP100 and UFBGA100 packages.
