Product Introduction

Overview

The STM32H755XIH3 is a high-performance microcontroller from STMicroelectronics, part of the STM32H7 series. It is based on the dual-core architecture of the Arm® Cortex®-M7 and Cortex®-M4 32-bit RISC cores. The Cortex®-M7 core operates at up to 480 MHz, while the Cortex®-M4 core operates at up to 240 MHz. Both cores feature a floating-point unit (FPU) and support Arm® single- and double-precision operations, along with a full set of DSP instructions and a memory protection unit (MPU) for enhanced security.

This microcontroller is equipped with high-speed embedded memories, including a dual-bank Flash memory of 2 Mbytes and up to 1 Mbyte of RAM. It also features an extensive range of enhanced I/Os and peripherals connected to APB, AHB buses, and a multi-layer AXI interconnect.
