STM32F303RDT6

STM32F303RDT6 is a mid‑range STM32F3 MCU from STMicroelectronics. It uses a 32‑bit ARM Cortex‑M4F core with DSP/FPU, optimized for fast control and signal processing tasks. It runs up to about 72 MHz and includes on‑chip Flash and RAM, plus rich mixed‑signal peripherals.
In the 64‑pin LQFP variant (RDT6), you typically get:
- 12‑bit ADCs, 12‑bit DACs, and analog front‑ends (comparators/op-amps)
- multiple timers (including advanced motor-control timers) and PWM
- memory: on‑chip Flash and RAM (sizes vary by exact part)
- communications: USART/UART, I2C, SPI, USB FS on supported devices, and CAN on some variants
- DMA, CRC, and power-management features
Commonly used for motor control, power electronics, sensor processing, audio, and mixed-signal applications. Supply voltage ~2.0–3.6 V; multiple low‑power modes are available.
Development workflow: STM32CubeMX for configuration, HAL/LL libraries, and standard IDEs (Keil, IAR, STM32CubeIDE). Always verify exact Flash/RAM and peripherals from the specific datasheet for F303RDT6.
