The STM32F3 Series combines a 32-bit Arm® Cortex®-M4 core (with FPU and DSP instructions) running at 72 MHz with a high number of integrated analog peripherals leading to cost reduction at application level and simplifying application design, including:

• Ultra-fast comparators (25 ns)

• Op-amp with programmable gain

• 12-bit DACs

• Ultra-fast 12-bit ADCs with 5 MSPS (Million Samples Per Second) per channel (up to 18 MSPS in Interleaved mode)

• Precise 16-bit sigma-delta ADCs (21 channels)

• Core Coupled Memory SRAM (Routine Booster), a specific memory architecture boosting time-critical routines, accelerating the performance by 43%

• 144 MHz Advanced 16-bit pulse-width modulation timer (resolution < 7 ns) for control applications

• High resolution timer (217 picoseconds), self-compensated vs power supply and temperature drift

A flexible interconnect matrix allows autonomous communication between peripherals and saves CPU resources and power consumption.

A high degree of compatibility with STM32F0 Series guarantees outstanding efficiency when designing derivatives of applications at different performance levels.

The STM32F3 Series of mixed-signal microcontrollers consists of:

• The STM32F301, STM32F302, STM32F303 general-purpose product lines ranging from a basic, cost-efficient peripheral set, up to more performance and analog functions able to manage up to triple FOC motor control,

• The STM32F334 with high-resolution timer (217 picoseconds) and complex waveform builder plus event handler (HRTIM) for digital power conversion, such as digital switched-mode power supplies, lighting, welding, solar and wireless charging,

• The STM32F373, with 16-bit sigma-delta ADC and 7 built-in
