Product Introduction

Overview

The STM32G474RET6U is a high-performance microcontroller from STMicroelectronics, based on the Arm® Cortex®-M4 32-bit RISC core. This device operates at a frequency of up to 170 MHz and features an Adaptive Real-Time (ART) accelerator, allowing 0-wait-state execution from Flash memory. The Cortex-M4 core includes a single-precision floating-point unit (FPU), digital signal processing (DSP) instructions, and a memory protection unit (MPU) for enhanced security. The microcontroller is equipped with 512 Kbytes of Flash memory and 128 Kbytes of SRAM, along with various protection mechanisms for embedded memory.
