STM32G483RE

The STM32G483RE is a high-performance 32-bit microcontroller from STMicroelectronics, based on the ARM Cortex-M4 core with FPU (Floating-Point Unit), operating at up to 170 MHz. It features 512 KB of Flash memory and 128 KB of SRAM, enabling efficient execution of complex control algorithms and real-time processing tasks. The device supports a wide supply voltage range from 1.7 V to 3.6 V, making it suitable for diverse power environments. This microcontroller includes advanced analog peripherals such as two 12-bit ADCs with up to 16 channels each, supporting simultaneous sampling and hardware oversampling for enhanced precision. It also integrates two operational amplifiers and a comparator, ideal for sensor interfacing and signal conditioning in industrial and consumer applications. Additionally, the STM32G483RE offers a rich set of communication interfaces, including USART, SPI, I2C, and USB 2.0 FS, facilitating seamless connectivity with external devices and systems. Security is addressed through built-in features like a true random number generator (TRNG), secure boot, and read-out protection, ensuring robust protection against counterfeiting and unauthorized access. The device supports low-power modes—including Stop, Standby, and Shutdown—allowing optimized energy consumption in battery-powered or energy-sensitive applications. The STM32G483RE is designed for motor control, power conversion, and industrial automation, where high-speed processing and precise analog control are critical. Its integrated digital-to-analog converter (DAC) and programmable timers support field-oriented control (FOC) algorithms, making it well-suited for brushless DC motor (BLDC) and PMSM applications. Furthermore, the inclusion of a flexible watchdog timer and error correction code (ECC) for memory enhances system reliability in harsh environments. With a comprehensive set of development tools and support from ST’s ecosystem—including STM32CubeMX, STM32CubeIDE, and HAL libraries—the STM32G483RE enables rapid prototyping and efficient software development. Its scalable architecture allows migration across the STM32G4 series, offering flexibility for future design expansions.
