概要
Description
STM32F746IET6 is a high‑performance 32‑bit MCU from STMicroelectronics in the STM32F7 family. It targets demanding embedded apps with a Cortex‑M7 core.
- Core and speed: ARM Cortex‑M7, up to 216 MHz, with single‑precision FPU, DSP instructions, and caches (plus an ART accelerator) for fast execution.
- Memory: device‑dependent; typical F746 parts offer up to 1 MB Flash and hundreds of KB RAM.
- Peripherals: wide I/O including USB (OTG), CAN, SDIO, multiple USART/SPI/I2S, ADCs, DAC, timers, etc. Includes LTDC for LCD/TFT graphics on many F7 parts.
- Package/grade: IET6 denotes a specific package (LQFP style) and temperature grade (industrial/extended range) per ST naming.
- Development: supported by STM32CubeMX/CubeIDE with HAL/LL drivers, with abundant examples and ecosystem.
- Use cases: HMI and graphics, high‑end audio/multimedia, motor control, embedded vision, and other CPU‑intensive tasks requiring Cortex‑M7 performance.
Note: exact flash/RAM sizes and peripherals vary by package; check the datasheet for your device variant.

Equivalent
Within ST’s line, the closest equivalents are other STM32F7 devices with a similar Cortex‑M7 core and the same 100-pin footprint, such as STM32F745, STM32F756, STM32F767 and STM32F769 variants. They mainly differ in flash/RAM, peripherals, and max speed. For drop-in compatibility, check exact pinout and memory in the datasheet. If more performance is required, consider higher-end H7 parts (e.g., STM32H745/747).
