STM32H7A3VGT6
Overview
The STM32H7A3VGT6 is a high-performance ARM Cortex-M7 microcontroller operating at up to 280 MHz. It features 2 MB of Flash memory and a massive 1.4 MB of SRAM, providing the computational density required for sophisticated embedded systems without external memory.
Why Choose This Part
This MCU offers a unique balance of high-speed processing and power efficiency with its specialized switch matrix and Chrom-GRC for reduced memory footprint in circular displays. The 1376 KB of internal RAM allows for large data buffers and complex algorithms without the power or PCB space penalties of external SDRAM.
Applications
Getting Started
Development is best supported by the STM32CubeH7 MCU Package and the STM32CubeIDE ecosystem. For hardware evaluation, the NUCLEO-H7A3ZI-Q provides a standardized platform with full access to the internal peripherals and on-board ST-LINK debugger.
