STM32H7A3IIK6Q

STM32H7A3IIK6Q is a high‑performance microcontroller from STMicroelectronics’ STM32H7 family. It features a dual‑core architecture: Cortex‑M7 main core (up to ~480 MHz) and a Cortex‑M4 companion core (up to ~240 MHz) for real‑time control and signal processing. The A3 subfamily targets demanding automotive/industrial applications, offering multi‑megabyte Flash, large RAM, and a rich I/O/peripheral mix. Peripherals typically include USB, Ethernet, CAN FD, SPI/QPI, SDIO, LCD controller, and external memory interfaces, plus cryptography accelerators (AES, SHA, RSA) and RNG. It supports various power modes for energy efficiency. Development is via STM32CubeMX/HAL/LL tools in STM32CubeIDE with ST‑LINK debugging. The IIK6Q suffix denotes a specific package and configuration; check the datasheet for exact pinout, memory, and temperature range.
