Overview
Description
STM32F303VCT6TR is a 32‑bit microcontroller from ST’s STM32F3 family, optimized for mixed‑signal and control applications. It uses an ARM Cortex‑M4F core with floating‑point DSP up to 72 MHz. Memory and peripherals are geared for compact, sensor/drive systems: up to 256 KB of flash and about 40 KB of RAM (package‑dependent); rich peripherals including USB Full‑Speed device, CAN, I2C, SPI, USART, and multiple timers. On‑chip analog capabilities include dual 12‑bit ADCs (with DMA), plus on‑chip analog conditioning features. The VCT6 suffix indicates a specific package variant (and TR denotes tape‑and‑reel). Development is streamlined with ST’s HAL/LL libraries and STM32CubeMX. Common applications include motor control, power electronics, data acquisition, USB devices, and other mixed‑signal sensing tasks.
