概述

Description

STM32G474RCT3 is a 32‑bit MCU from ST’s STM32G4 family, designed for mixed‑signal and motor‑control applications. It combines an ARM Cortex‑M4F core (DSP instructions and FPU) up to about 170 MHz with rich analog and timing peripherals. On‑chip analog includes multiple 12‑bit ADCs, DACs, and programmable op‑amps/comparators, plus advanced control timers suitable for motor control. It provides DMA and multiple connectivity options (USART/UART, SPI, I2C, CAN FD, USB, etc.). Memory options cover flash and RAM sized to fit mid‑volume products; check the exact variant for precise quantities. The G4 feature set emphasizes motor control accelerators, digital filtering, and integrated power‑stage support. The RCT3 suffix specifies a particular package and temperature grade; see the datasheet for pin count and footprint. Development is supported by STM32CubeMX, HAL/LL libraries, and common IDEs (Keil, IAR, SW4STM32). Suitable for motor control, power electronics, audio, and other mixed‑signal applications.
