STM32F427AIH6

STM32F427AIH6 is a high‑performance 32‑bit MCU from ST’s STM32F4 family. It uses an ARM Cortex‑M4 core with a floating‑point unit and DSP instructions, typically clocked up to about 180 MHz, and includes flash access acceleration (ART). It offers a rich peripheral set: USB OTG, CAN, SDIO, SPI/I2C/UART, multiple timers, ADCs/DACs, and a TFT LCD controller; it also supports camera interfaces (DCMI) and, on some variants, Ethernet MAC. It provides DMA, memory protection, and configurable power modes for efficient operation, with flexible flash and RAM options. The AIH6 suffix indicates a specific package/temperature grade; consult ST’s datasheet for exact pinout, package type (e.g., LQFP) and electrical specs. Applications include motor control, industrial automation, multimedia, and general embedded systems requiring performance and peripherals beyond entry‑level MCUs. Development is supported via STM32CubeMX/CubeIDE with HAL/LL drivers. If you need precise specs (flash RAM sizes, package details, or peripherals for this exact SKU), I can pull the official datasheet snippet.
