STM32H747AII6

STM32H747AII6 is a high‑performance microcontroller from STMicroelectronics’ STM32H7 family. It uses a Cortex‑M7 core (up to about 480 MHz) and, in this family variant, a secondary Cortex‑M4 core for real‑time tasks, delivering strong DSP and control performance with efficiency. It’s designed for demanding applications such as motor control, multimedia, imaging, and graphics, demanding compute and I/O throughput.
Key features (typical):
- Large on‑chip memory with external memory support (Flash/RAM, FSMC/LCD interfaces).
- Rich peripherals: USB (OTG HS/FS), CAN FD, SDIO, Ethernet, LCD‑TFT controller, camera interfaces, audio, timers, ADC/DAC, cryptography accelerators and RNG.
- Modern memory/subsystem: caches, MPU, security features, flexible power/performance modes.
- Package: AI I6 variant (specific pinout/footprint); supported by STM32CubeIDE/CubeMX with HAL/LL drivers.
For exact specs (core speeds, memory sizes, peripheral counts) see the official datasheet/product page.
