STM32® 32-bit MCU Family

Leading supplier of ARM® Cortex®-M microcontrollers

STM32F3 Series of Mixed-Signal MCUs with DSP and FPU Instructions

STMicroelectronics' 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 peripherals including:

  • Analog: fast 12-bit ADC at 5 Msymb/s (0.2 μs), precise 16-bit sigma delta ADC, fast and ultra-fast comparators (25 ns), op amp with PGA (4 gains, 1% accuracy) and 12-bit DACs
  • Up to 18 timers with 16- and 32-bit resolution running up to 144 MHz
  • Audio: simplex or full-duplex I²S interfaces
  • Large set of communication interfaces including USART (9 Mbit/s), SPI/I²S (18 Mbit/s), I²C (1 MHz in Fast+ mode), CAN (1 Mbit/s), and full-speed USB
  • Cyclic redundancy check (CRC)
  • Capacitive touch sensing (24 keys)
  • High-resolution timer (217 ps) with complex waveform builder and multi-event handler

Package options are LQPF48/64/100, UFBGA100, UQFN32 and WLCSP66/49.
Temperature range from -40 to 85 °C or from -40 to 105 °C
