Product details

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

Internal oscillator and brown-out detect are included.
