STM32H755ZIT6
Overview
The STM32H755ZIT6 is a high-performance dual-core microcontroller featuring an ARM Cortex-M7 core running at 480MHz and a Cortex-M4 core running at 240MHz. It integrates 2MB of Flash memory and 1MB of RAM, providing the computational overhead required for complex real-time applications and rich graphical interfaces. This device utilizes a dual-core architecture to offload communication and housekeeping tasks to the M4 core while the M7 handles intensive processing.
Why Choose This Part
The dual-core architecture allows for hardware-level isolation between safety-critical code and communication stacks. It features extensive connectivity including Dual-mode Quad-SPI, Ethernet, and USB OTG, alongside advanced security features like secure firmware upgrade support and active tamper detection. The 480MHz clock speed combined with L1 cache and the ART Accelerator ensures zero-wait-state execution from Flash.
Applications
Key Specifications
Getting Started
Start development with the NUCLEO-H755ZI-Q evaluation board, which provides an on-board ST-LINK debugger and easy access to all I/O. Use the STM32CubeIDE for integrated code generation and debugging, and leverage the STM32CubeH7 software package for middleware and dual-core communication examples. Ensure the power strategy accounts for the SMPS step-down converter to optimize efficiency at high clock speeds.
