STM32F3 Series

STM32 F3 series of mixed-signal MCUs with DSP and FPU instructions

The STM32 F3 series combines a 32-bit ARM Cortex-M4 core (DSP, FPU) running at 72MHz with an advanced analog peripheral set to reduce BOM cost and simplify application board design, including:

  • Fast comparators (50 ns)
  • Programmable gain amplifiers (4 gain ranges)
  • 12-bit DACs
  • Fast 12-bit ADCs (5 MSPS per channel with up to 18 MSPS in interleaved mode)
  • 16-bit sigma-delta ADCs
  • Fast 144 MHz motor control timers, timing resolution better 7 ns

This series allows you to easily upgrade from the STM32 F1 series by adding a higher performance core and enhanced peripherals. It consists of:

  • The STM32F302 line to give general-purpose applications a competitive edge, and pin compatible with the corresponding STM32 F1 devices
  • The STM32F303/313 line, offering even more performance thanks to a specific memory architecture allowing execution of time-critical routines in ultra-fast RAM memory
  • The STM32F373/383 line with an on-board, 3-channel, 16 bit sigma-delta ADC for high precision sensing in applications such as biometric sensors or smart metering

Package options are WLCSP66 (less than 4.3 x 4.3 mm), LQPF48, LQFP64, LQFP100 and UFBGA100 for the devices ranging from 64 to 256 Kbytes of Flash.
