STM32F746IET6

STM32F746IET6 is a high‑performance MCU from ST’s STM32F7 family, built around the ARM Cortex‑M7 core. It delivers strong single‑thread performance (up to 216 MHz) with a single‑precision FPU and DSP instructions, I/D caches, and a memory protection unit for real‑time control and graphics tasks.
Key specs (typical for this device variant):
- Memory: up to around 1 MB Flash and up to ~320 KB RAM (exact amounts depend on package).
- Peripherals: USB OTG, CAN, multiple USART/UARTs, SPI, I2C, SDIO, timers, 12‑bit ADCs, DACs, plus an LCD‑TFT controller (LTDC) with graphics support.
- Memory interfaces: external memory interface options (FSMC/SDRAM) for large RAM/frames.
- Development: supported by STM32Cube HAL/LL libraries and tools; compatible with common IDEs (MDK, IAR, SW4STM32) and CubeMX for code generation.
- Power modes: various low‑power options for battery or embedded applications.
Applications: graphics/UI displays, multimedia, motor control, industrial automation, and other high‑performance embedded roles.
Note: exact memory sizes, peripherals, and package details vary by part and package. Refer to the datasheet for precise specs of the IET6 variant.
