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 STM32 F3 series 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 gains for high-precision measurements in applications such as biometric sensors or smart metering.
The STM32F3x8 line, supporting 1.8 volt operation.
