480 MHz Cortex-M7 — what it means for the control loop
The STM32H743IIT6 runs a single ARM Cortex-M7 core at 480 MHz. It has 2 MB Flash and 1 MB RAM. The 140 I/O pins in a 176-LQFP package give plenty of GPIO for parallel displays, external memory buses, or sensor arrays. Connectivity covers CANbus, Ethernet, USB OTG, multiple SPI/I²C/UART, and SDIO — so this MCU can act as a central gateway on a factory floor or a smart display controller in an HMI panel.
Industrial temperature range and environment
Rated for -40°C to 85°C ambient. Internal oscillator and brown-out detect are included.
Lifecycle and sourcing reality
The STM32H743IIT6 is listed as active in production, but the STM32H7 series has seen EOL notices on some density variants. For a BOM freeze, confirm the latest PCN status at quote time. This part is sourced and quoted to order through independent distribution — availability and current pricing confirmed when you submit an RFQ.
