Présentation

Description

The STM32F303VBT6 is a mixed-signal MCU from STMicroelectronics, based on the ARM Cortex-M4 core (with FPU) running at 72 MHz. It features 128 KB Flash, 40 KB SRAM, and a rich set of peripherals including:
- Analog: 4x 12-bit ADCs (5 Msps), 2x 12-bit DACs, comparators.
- Timers: 12x 16/32-bit timers, including motor control and HRTIM.
- Communication: 3x USART, 2x SPI, 3x I²C, CAN, USB FS.
- Digital: GPIOs (up to 80), DMA, CRC, and hardware encryption.
It operates at 2.0–3.6V and is ideal for industrial, consumer, and medical applications requiring high-speed analog processing or motor control. Packaged in a LQFP100 form factor, it balances performance and power efficiency.
Key strengths: High-speed ADCs, FPU support, and versatile peripherals.
