STMicroelectronics — STM32G474 Series Microcontrollers

STMicroelectronics STM32G474 Series Microcontrollers

32-bit MCUs offer integrated feature set for digital power-system control

The STM32G474 microcontrollers from STMicroelectronics enable the implementation of high-performance power systems which use digital control to achieve high precision and to provide design flexibility.


Key features for digital power control in the STM32G474 include a filter-math accelerator (FMAC) to handle functions such as 3p/3z compensation, and to ensure high efficiency across the load range. The STM32G474 can also perform digital slope compensation, freeing CPU cycles for other functions. The MCUs provide a rich set of analog features, including five fast 12-bit ADCs, seven comparators, six operational amplifiers, seven DAC channels, an internal voltage reference buffer, a low-power real-time clock, and multiple high-resolution timers.


The STM32G474 devices are based on the Arm® Cortex®-M4 core operating at a frequency of up to 170 MHz. The Cortex-M4 core features a single-precision floating-point unit which supports all the Arm single-precision data-processing instructions and all the data types. It also implements a full set of DSP instructions, and a memory protection unit for enhanced security.


High-speed memory provision includes either 128 kbytes, 256 kbytes or 512 kbytes of Flash, and 128 kbytes of SRAM. The STM32G474 also features a quad SPI to external Flash memory. It includes several protection mechanisms for its embedded Flash memory and SRAM:

  • Read-out protection
  • Write protection
  • Secure memory area
  • Proprietary code read-out protection

The STM32G474 MCUs are available in ten package options which have up to 128 pins.


  • High resolution timer and wave form builder with 184 ps resolution
  • Three CAN-FD controllers
  • Four I2C interfaces
  • Four serial peripheral interfaces
  • Serial audio interface
  • USB 2.0 Full-Speed interface
  • IRTIM infrared interface


  • Drones
  • Small electric vehicles
  • Radio-controlled vehicles

Development Board

Board Part Number: B-G474E-DPOW1

The B-G474E-DPOW1 Discovery kit is a digital power solution and development platform for the STM32G474RET6 MCU. The kit, based on the USB 2.0 FS Type-C™ connector interface, helps the designer to develop digital power applications such as a buck-boost converter, RGB power LED lighting, or a Class D audio amplifier.
