Description
STM32H7A3IGT6 is a high-performance MCU from STMicroelectronics in the STM32H7 family. It uses a dual-core Arm Cortex-M architecture (Cortex-M7 main core with a Cortex-M4 partner) for compute-intensive real-time control, signal processing and mixed workloads, with peripherals kept responsive.
Key features:
- Dual-core: M7 up to ~480 MHz and M4 up to ~240 MHz (configurations vary by package)
- Large memory and flexible protection for safety and reliability
- Rich peripherals: USB, Ethernet, CAN, multiple serial interfaces, LCD-TFT controller, multiple ADCs/DACs, timers, and advanced DMA
- Security/safety: hardware crypto engine, MPU, secure boot (where supported)
- Development: supported by STM32CubeIDE, CubeMX, HAL/LL drivers and evaluation boards
Typical applications: motor control, industrial automation, automotive and safety-critical systems, embedded vision and price/performance-sensitive devices.
Package: IGT6 variant (pinout/package specifics in the datasheet). For exact specs, consult the STM32H7A3 datasheet and reference manuals.
