Product Details The STM32G474RBT3 is a 32-bit microcontroller from STMicroelectronics' STM32G4 series, based on a high-performance Arm Cortex-M4 core with floating-point and DSP capabilities. It operates at frequencies up to 170MHz and combines processing performance with advanced analog, timing and control peripherals for demanding embedded applications.The STM32G474RBT3 provides 128KB of Flash memory and 128KB of SRAM. The integrated memory resources can be used for application firmware, control algorithms, runtime data and embedded communication functions. The device operates from a 1.71V to 3.6V supply range, supporting a variety of embedded system power architectures.The microcontroller includes hardware acceleration functions such as CORDIC for trigonometric calculations and FMAC for filter-related mathematical operations. These accelerators can help reduce CPU workload in real-time control, motor-control and digital signal-processing applications.The STM32G474RBT3 also integrates a wide range of analog peripherals, including high-performance ADCs, DACs, operational amplifiers and comparators. This high level of integration allows designers to combine measurement, signal conditioning and control functions within a single microcontroller-based system.Advanced timer resources make the device suitable for applications requiring precise PWM generation and real-time control. The STM32G4 architecture also provides communication peripherals for connecting the MCU with sensors, drivers, displays, external controllers and other electronic devices.The STM32G474RBT3 is supplied in a 64-pin LQFP package measuring approximately 10mm × 10mm, making it suitable for surface-mount control boards where a combination of processing capability and peripheral integration is required. ST specifies the T3 ordering variant for an operating temperature range of -40°C to +125°C.Typical applications include motor control, digital power conversion, industrial automation, robotics, energy management and smart appliances. The combination of a 170MHz Cortex-M4 core, mathematical accelerators, high-performance analog functions and advanced timers makes the STM32G474RBT3 particularly useful for embedded systems requiring real-time processing and precise control.For hardware designers, the STM32G474RBT3 provides a highly integrated platform for developing control boards and embedded electronic equipment. Its processing performance, memory resources and specialized peripherals allow multiple control and measurement functions to be implemented with a reduced number of external devices.
