STM32G473QE

The STM32G473QE is a high-performance microcontroller from STMicroelectronics, based on the Arm Cortex-M4 core running at up to 170 MHz. It features a 1 MB Flash memory and 192 KB of SRAM, enabling efficient storage and execution of complex applications. The device supports single-cycle multiply-accumulate (MAC) operations and floating-point unit (FPU), making it well-suited for real-time signal processing tasks. This microcontroller integrates a rich set of peripherals including two advanced analog-to-digital converters (ADCs) with up to 16 channels each, supporting fast sampling rates and high precision. It also includes a digital-to-analog converter (DAC), operational amplifiers, and comparators for sensor interfacing and analog signal conditioning. Communication interfaces include up to three USARTs, two SPIs, two I2Cs, and a CAN FD controller, facilitating robust connectivity in industrial and automotive systems. Security features such as hardware encryption (AES), secure boot, and read-out protection enhance system integrity and protect intellectual property. The STM32G473QE operates across a wide voltage range (1.71–3.6 V), ensuring compatibility with various power supply configurations. Its low-power modes—sleep, stop, and standby—enable energy-efficient operation in battery-powered or portable devices. Designed for demanding applications, the STM32G473QE excels in motor control, power conversion, and industrial automation due to its integrated high-resolution timers and PWM generators. It also supports advanced control algorithms through its DSP instructions and FPU, making it ideal for real-time control of BLDC and PMSM motors. Additionally, it can be used in medical devices, consumer electronics, and IoT gateways where reliability, performance, and peripheral integration are critical. The chip is packaged in a 64-pin LQFP package, offering a balance between pin count and board space efficiency. It is supported by ST’s comprehensive development ecosystem, including STM32CubeMX for configuration, STM32CubeIDE for development, and a wide range of evaluation boards and reference designs. This ensures rapid prototyping and seamless integration into diverse embedded projects.
