STM32G474RCT3

STM32G474RCT3 is a 32‑bit MCU from STMicroelectronics’ STM32G4 family, based on the ARM Cortex‑M4F core (DSP instructions and single‑precision FPU). It’s aimed at motor control and mixed‑signal applications, offering a good balance of performance, peripherals, and energy efficiency.
Typical features (high level):
- Cortex‑M4F core with DSP and FPU
- Advanced timers (including motor‑control/PWM)
- Analog peripherals: ADCs, DACs, op‑amps, comparators
- Communications: USB Full‑Speed, CAN, USART/UART, SPI, I2C
- DMA and memory protection (and often CRC/security features)
- On‑chip Flash and RAM (sizes vary by exact part)
- 48‑pin package (RC variant) and specified operating temperature range
For exact Flash/RAM sizes, pinout, and electrical specs, see the STM32G474RCT3 datasheet and reference manual on ST’s website.
