480 MHz Cortex-M7 — what the core clock buys the design
The STM32H743IGT6: The ARM Cortex-M7 core runs at 480 MHz, with 1 MB of Flash and 1 MB of RAM, both organised as 1M x 8.
Connectivity and peripheral set — Ethernet, CAN, and beyond
This MCU integrates Ethernet MAC, two CAN interfaces (CANbus), USB OTG, and a broad serial complement: SPI, I²C, UART/USART, I²S, SAI, SPDIF, and SWPMI. For display-driven designs, the LCD controller and DMA engine offload pixel data movement from the core. The 140 I/O count in the 176-LQFP package gives enough headroom for sensor arrays, actuator banks, and parallel buses without needing a larger footprint.
It is not AEC-Q100 qualified, so it is not a direct fit for under-hood automotive modules, but it is fine for cabin or infotainment systems that operate within the industrial temperature envelope. The 176-LQFP (24x24 mm) package is a standard QFP with 0.5 mm pitch — hand-solderable in rework, no BGA X-ray inspection needed. The tray shipping medium is typical for this package size; reeling is available through alternate order codes if pick-and-place volume demands it.
