STM32H7R3/S3 Microcontrollers

STMicroelectronics STM32H7R3/S3 Microcontrollers feature an Arm® Cortex®-M7 processor with a clock speed of 600MHz. The STMicroelectronics STM32H7R3/S3 MCUs are cost-effective solutions that feature Bootflash MCUs with high-speed external memory interfaces, ensuring real-time eXecute-in-Place (XiP) capabilities. Additionally, the microcontrollers support 2D GUI up to WSVGA resolution with limited CPU load, allowing more resources for real-time tasks.
