STM32G473ME

The STM32G473ME is a high-performance microcontroller from STMicroelectronics, part of the STM32G4 series based on the ARM Cortex-M4 core running at up to 170 MHz. It features a 32-bit RISC architecture with floating-point unit (FPU) support, enabling efficient execution of complex mathematical operations essential for real-time control applications. The device offers up to 1 MB of Flash memory and 192 KB of SRAM, providing ample space for firmware storage and fast data processing. This microcontroller integrates advanced analog peripherals including two 12-bit ADCs with up to 16 channels each, supporting differential and single-ended input modes, as well as a dual-channel DAC for precise signal generation. It also includes multiple operational amplifiers and comparators, making it ideal for sensor interfacing and signal conditioning in industrial and consumer systems. Communication interfaces consist of up to four USARTs, three SPIs, three I2Cs, one CAN FD, and one USB 2.0 full-speed interface, facilitating flexible connectivity in multi-node environments. The STM32G473ME supports low-power operation through various power-saving modes, including Stop, Standby, and Shutdown, with fast wake-up times, which makes it suitable for battery-powered or energy-efficient designs. It includes an embedded security module with hardware encryption engines (AES-256, RNG), secure boot, and tamper detection, enhancing system integrity and protection against unauthorized access. Designed for demanding applications, this MCU excels in motor control, power conversion, and industrial automation, where precision timing, fast response, and robust analog integration are critical. Its rich set of peripherals—such as timers with PWM outputs, quadrature encoder interface, and event management units—enables precise control of BLDC motors, inverters, and servo systems. Additionally, the integrated digital filters and programmable logic blocks allow for custom signal processing without external components. The device operates across a wide supply voltage range (1.8 V to 3.6 V), ensuring compatibility with diverse power architectures. It is available in a 64-pin LQFP package, offering a balance between pin count and integration for compact PCB designs. With comprehensive development tools from ST, including STM32CubeMX for configuration and STM32CubeIDE for coding and debugging, the STM32G473ME accelerates time-to-market for engineers developing high-efficiency, safety-critical embedded systems.
