The STM32H743ZGT6 is an STMicroelectronics STM32H7 series MCU built around a single ARM Cortex-M7 core clocked at 480 MHz. That core speed, combined with 1 MB of program Flash and 1 MB of RAM, puts it in the high-performance tier for real-time control, audio processing, and communications-intensive applications. The part integrates a rich peripheral set including dual CAN, Ethernet, multiple SPI/I2C/UART interfaces, a parallel EBI/EMI bus, and USB OTG — enough connectivity to serve as the system controller in a motor drive, an HMI gateway, or an industrial automation node. On-chip data converters (36-channel 16-bit ADC, dual 12-bit DAC) reduce external analog front-end components.
Memory and I/O headroom
The 114 general-purpose I/O pins, available in the 144-LQFP package, provide ample GPIO for parallel displays, sensor arrays, and external bus interfaces.
Package and thermal considerations for layout
The STM32H743ZGT6 ships in a 144-pin LQFP with a 20x20 mm body (0.5 mm pitch). This is a standard surface-mount footprint — no hidden balls, no via-in-pad required.
