The STM32F3 family of mixed‑signal MCUs with DSP and FPU instructions

with a high number of integrated analog and digital peripherals leading to cost reduction at application level and simplifying application design.

The STM32F3 Series consists of six lines:

•

The

STM32F301, STM32F302, STM32F303 lines are general‑purpose MCUs ranging from a basic, cost‑efficient

peripheral set to devices with more performance and analog functions.

•

The

STM32F334 line includes a versatile high‑resolution timer (217 ps) for digital power conversion applications,

such as D‑SMPS, lighting, welding, solar and wireless charging.

•

The

STM32F373 line with its 16‑bit sigma‑delta ADC is designed for high‑precision measurements in applications

such as biometric sensors or smart metering.

•

The

STM32F3x8 line supporting 1.8 V operations.

The same system implementation is common

within the STM32F3 series. Migration across

product lines is facilitated as the same

peripheral, IP‑set and pinout are shared.
